TECHNICAL FIELD 
     The present invention relates to television systems, broadcast reception devices and operation terminals, such as television broadcast reception devices and set top boxes, which receive television broadcast programs, streaming data and the like, and recommend programs to the user&#39;s taste. 
     BACKGROUND ART 
     In recent years, digital broadcasting has progressed, and it has become possible for different programs to have extra information. There is a program recommending function for recommending programs to the user&#39;s taste and showing this program information using the above described extra information and the viewer&#39;s viewing history. Unexamined Japanese Patent Publication No. 2002-112186 discloses a technology for showing information on recommended programs in a display format in accordance with the degree of recommendation of the programs. 
       FIG. 17  shows a TV screen displaying conventional recording recommending program table  101 , which is a list of recommendations for programs for recording. In addition,  FIG. 18  shows a remote control for operating the list of recommendations. Recording recommending program table  101  in  FIG. 17  is a table formed of axis of degree of recommendation  102  along which programs for recording are shown in order from the highest degree of recommendation at the top to the lowest degree of recommendation at the bottom, and axis of time for recording  103  along which the time for recorded programs is shown. In addition, the remote control in  FIG. 18  is an operation terminal having recording recommending program table button  105  for displaying recording recommending program table  101 , selection button  106  for moving program selection cursor  104  which highlights parts of the program table, and determination button  107  for determining the program to be viewed. 
     The user presses recording program table button  105  on the remote control, and thus, recording recommending program table  101  is displayed. Then, the user presses selection button  106  in the case where there is a program they desire to view among the programs for recording, so that program selection cursor  104  is adjusted to a point where the program the user wishes to view is displayed. In the case where the program to which program selection cursor  104  is adjusted is viewed, the user presses determination button  107  and views the recommended program. In this configuration, while a recommended program can be selected in the list of recommendations and viewed, the operation for selecting a recommended program by moving the selection cursor in the list of recommendations displayed on the screen is complicated. 
     There is the following problem with the prior art shown in Unexamined Japanese Patent Publication No. 2002-112186. 
     In accordance with the method for informing the user of recommended programs through the conventional program recommending function, a list of recommendations is displayed on the screen, and the selection cursor is moved in the displayed list of recommendations, so that a recommended program is selected. That is to say, a number of operations are required in the operation terminal in order to view a recommended program. Furthermore, as television broadcast reception devices have progressed, the number of functions has increased, making operation using the operation terminal complicated, and therefore, there is a problem, such that the user cannot smoothly operate the operation terminal. In addition, the list of recommendations is displayed on the screen, and therefore, the user cannot be informed of recommended programs while viewing TV images. 
     DISCLOSURE OF THE INVENTION 
     The present invention solves the above described problems with the prior art, and provides a television system made up of a television broadcast reception device and an operation terminal, which makes programs to the user&#39;s taste easy to view. 
     The television system according to the present invention allows the television broadcast reception device to transmit information on the user&#39;s taste for programs to the user&#39;s taste to the operation terminal, outputs the information that a program to the user&#39;s taste exists in the operation terminal so that the user can select a program they like, and transmits the selected program information to the television broadcast reception device. As a result, it can be seen on the operation terminal that there is a program to the user&#39;s taste, and thus, it becomes possible to view a program to the user&#39;s taste with a simple operation. 
     In addition, in the television system according to the present invention, in the case where the operation terminal receives a number of pieces of information to the user&#39;s taste from the television broadcast reception device, the respective pieces of information showing that programs to the user&#39;s taste exist are outputted in different formats when information showing that programs to the user&#39;s taste exist is outputted. As a result, when information showing that a number of programs to the user&#39;s taste exist is outputted, the user can easily see the difference between the number of outputted programs to the user&#39;s taste. 
     In addition, the television system according to the present invention has a determination part for determining the degree of the user&#39;s taste for programs, and outputs information showing that programs to the user&#39;s taste exist in different formats based on the determined degree of the user&#39;s taste for programs. As a result, when the degree of the user&#39;s taste for programs is determined, this can be used to detect programs to the user&#39;s taste, and in addition, when the degree of the user&#39;s taste for programs is used, the order for recommending the programs to the user can be set. 
     In addition, the operation terminal of the television system according to the present invention has numbers corresponding to respective channels of television broadcasts, and information on the user&#39;s taste for detected programs is allocated to numbers corresponding to the respective channels. As a result, the user can see which channel on the operation terminal is for the recommended program. 
     In addition, the television system according to the present invention has a location change detecting part for detecting if the location of the operation terminal has changed, so as to detect programs to the user&#39;s taste and output information showing that a program to the user&#39;s taste exists when a change in the location of the operation terminal is detected. As a result, programs to the user&#39;s taste can be recommended to the user with appropriate timing. 
     In addition, the television system according to the present invention detects programs to the user&#39;s taste when the power of the television broadcasting apparatus is turned on, and outputs information showing that programs to the user&#39;s taste exists. As a result, programs to the user&#39;s taste can be recommended to the user with appropriate timing. 
     In addition, the television system according to the present invention outputs information showing that programs to the user&#39;s taste exist, and stops outputting information showing that programs to the user&#39;s taste exist a program to the user&#39;s taste is selected. As a result, a situation where the information showing that programs the user&#39;s taste exist continues being outputted can be avoided, and the power consumed by the operation terminal can be reduced by stopping output. 
     In addition, the television system according to the present invention outputs information showing the programs to the user&#39;s taste exist, and then stops outputting information showing the programs to the user&#39;s taste exist in the case where no program to the user&#39;s taste is selected after a predetermined period of time or more has elapsed. As a result, a situation where the information showing that programs the user&#39;s taste exist continues being outputted can be avoided, and the power consumed by the operation terminal can be reduced by stopping output. 
     In addition, the television system according to the present invention determines whether or not the detected program to the user&#39;s taste and the program the user is viewing are the same, and in the case where the program to the user&#39;s taste and the program the user is viewing are the same, the information on the user&#39;s taste for the detected program is not transmitted to the operation terminal. As a result, the television broadcast reception device does not transmit the information on the user&#39;s taste to the operation terminal, and thus, the power consumed by the television broadcast reception device can be reduced. Furthermore, the operation terminal does not receive the information on the user&#39;s taste or output information showing that programs to the user&#39;s taste exist, and therefore, the power consumed by the operation terminal can also be reduced. 
     In addition, the television system according to the present invention has a user identifying part for identifying the user, and detects programs to the user&#39;s taste based on the information on the identified user&#39;s taste when the user is identified by the user identifying part, and outputs information showing that detected programs to the user&#39;s taste exist. As a result, programs to different users&#39; tastes can be recommended, even in the case where the television is shared by a number of users. 
     The television system according to the present invention allows the television broadcast reception device and the operation terminal to communicate, making it possible for programs to the user&#39;s taste to be seen on the operation terminal, and thus, a program to the user&#39;s taste can be easily selected.

     In the following, the first embodiment of the present invention is described with reference to the drawings. 
       FIG. 1  is a block diagram showing the configuration of television system  1  according to the first embodiment of the present invention. Television system  1  shown in  FIG. 1  is formed of television broadcast reception device  2  and operation terminal  3 . In addition, television broadcast reception device  2  is formed of antenna part  4 , broadcast receiving part  5 , separation part  6 , decoding part  7 , program outputting part  8 , program recommendation controlling part  9 , detection part  10 , data transmitting and receiving part  11 , program information storing part  12 , input part  13 , channel table  14 , information on user&#39;s taste storing part  15  and time measuring part  16 . Operation terminal  3  is formed of operation terminal controlling part  17 , information on user&#39;s taste receiving part  18 , transmission part  19 , output part  20  and selection part  21 . 
     First, television broadcast reception device  2  is described. Digital television broadcasts received by antenna part  4  are inputted into broadcast receiving part  5 . Then, the channel desired by the user where the broadcast signal is modulated is selected through control by the below described program recommendation controlling part  9 . 
     The modulated signal outputted by broadcast receiving part  5  is inputted into separation part  6 , which extracts program information (information relating to programs, such as EPG information) from demodulated MPEG-2 transport stream. This program information is stored in the below described program information storing part  12 . In addition, it is well known in digital television broadcasting that MPEG-2 transport stream is modulated for broadcast. 
     The MPEG-2 transport stream outputted by separation part  6  is inputted into decoding part  7 , which extracts and decodes the streams of image and speech sound of the program desired by the user through control of program recommendation controlling part  9 , and after that, outputs image signals of analog Y/Pb/Pr and speech sound signals of analog L/R. 
     The image signals of analog Y/Pb/Pr from decoding part  7  are inputted into program outputting part  8 , which amplifies these image signals. In addition, program outputting part  8  extracts a synchronization signal which is multiplexed with the analog Y signal, and after that, outputs an image signal which is amplified in sync with this synchronization system to a monitor, not shown. Furthermore, speech sound signals of analog L/R are inputted into program outputting part  8 , which amplifies these speech sound signals and outputs the resulting signal to speakers, not shown. 
     Program recommendation controlling part  9  has a detection part  10  and a data transmitting and receiving part  11 , and is a microcomputer for controlling the components of television broadcast reception device  2 . In addition, program recommendation controlling part  9  is connected to the below described program information storing part  12  in such a manner that write-in into information on user&#39;s taste storing part  15  is possible. Furthermore, program recommendation controlling part  9  stores program information outputted by separation part  6  in program information storing part  12 . Input part  13  is an interface for accepting the operation for inputting information on the user&#39;s taste and the like. Here, information on the user&#39;s taste refers to program titles, genre, time when programs start, time when programs finish and keywords for programs, and includes also items set as emergency information. Here, emergency information refers to broadcast program information in the case where urgent special news on a disaster is broadcast. In addition, the emergency information may be set by the user through input part  13  or set in advance by the manufacturer at the stage where the television is manufactured. It is possible to use a remote control, a keyboard or the like as input part  13 . Here, the below describe operation terminal  3  may function as input part  13 , or input part  13  may be implemented using the below described terminal which is different from operation terminal  3 . Operation by the user, such as input of information on the user&#39;s taste or changing of the channel, is converted to an electrical signal by input part  13  so as to be inputted into program recommendation controlling part  9  and then stored in information on user&#39;s taste storing part  15 . 
     Channel table  14  stores the relationship between the respective channels of the broadcasts received by television broadcast reception device  2  and the values (preset numbers) for selecting programs used in television broadcast reception device  2  and operation terminal  3  in a memory, and is used for presetting channels in such a manner that the channels and the present numbers correspond to each other. In addition, this relationship can be changed by the user. Here, an example of channel table  14  is described with reference to  FIG. 7 .  FIG. 7  is a table showing the relationship between broadcast channels  14   a  received by television broadcast reception device  2  and preset numbers  14   b  for selecting programs used in television broadcast reception device  2  and operation terminal  3 . The present number which corresponds to channel  2   ch  received by television broadcast reception device  2  is 2, the preset number which corresponds to channel  4   ch  is 4, the preset number which corresponds to channel  6   ch  is 6, the preset number which corresponds to channel  8   ch  is 8, the preset number which corresponds to channel  10   ch  is 10, and the preset number which corresponds to channel  19   ch  is 5. 
     Time information is inputted into detection part  10  through time measuring part  16 . Thus, detection part  10  uses information on the user&#39;s taste that has been inputted in information on user&#39;s taste storing part  15  and detects a program to the user&#39;s taste which is desired by the user from among the group of programs at the time when viewed by the user in the information on the programs inputted into program information storing part  12 . Program recommendation controlling part  9  transmits information on the user&#39;s taste of the detected programs to the user&#39;s taste to date transmitting and receiving part  11 . Information on the user&#39;s taste refers to programs to the user&#39;s taste, channels for emergency programs, values corresponding to the channels for identifying the program when a program is selected using operation terminal  3  and the like. 
     Data transmitting and receiving part  11  receives information on the user&#39;s taste from detection part  10 , makes transmission and reception of data to and from operation terminal  3  possible, and transmits information on the user&#39;s taste that has been transmitted to data transmitting and receiving part  11  from detection part  10  to information on user&#39;s taste receiving part  18  in operation terminal  3 . In addition, data transmitting and receiving part  11  receives the below described selected program information gained when the user selects a program through operation, from operation terminal controlling part  17  of the below described operation terminal  3 . The received selected program information is controlled by program recommendation controlling part  9 . Program recommendation controlling part  9  detects the channel corresponding to the selected program information received by operation terminal  3  from channel table  14 , and allows decoding part  7  to decode the program on the detected channel as a program desired by the user. In addition, the selected program is a program desired by the user, and therefore, program information on the selected program is stored as information on the user&#39;s taste. Thus, program recommendation controlling part  9  reads in the program information corresponding to the program selected from program information storing part  12  and stores the program information in information on user&#39;s taste storing part  15 . 
     Next, the configuration of operation terminal  3  is described. Operation terminal controlling part  17  is a microcomputer which has information on user&#39;s taste receiving part  18  and controls the components of operation terminal  3 . Information on user&#39;s taste receiving part  18  receives information on the user&#39;s taste from data transmitting and receiving part  11 . In addition, operation terminal controlling part  17  outputs information on the user&#39;s taste to output portion  20 , receives the below described selected program information from selection part  21 , and allows transmission part  19  to transmit the selected program information to data transmitting and receiving part  11 . Selection part  21  has output part  20  for outputting information showing that programs to the owner&#39;s taste exist and a program selection button, not shown, which, when pressed, allows for selection of a program. Selection part  21  is an interface for accepting the operation for selecting a program by the user, and is controlled by operation terminal controlling part  17 . 
     This information showing that programs to the user&#39;s taste exist is information for making the user see that programs to the user&#39;s taste exist, and refers to information that is provided based on the information on the user&#39;s taste received by operation terminal controlling part  17  or the information on the user&#39;s taste. Operation for selecting a program by the user is converted to an electrical signal by selection part  21  and transmitted to data transmitting and receiving part  11  from transmission part  19  as selected program information. According to the present embodiment, output part  20  makes a program selection button for viewing the program corresponding to the program to the user&#39;s taste emit light based on the information on the user&#39;s taste received by operation terminal controlling part  17 . That is to say, output part  20  prepares and outputs information showing programs to the user&#39;s taste exist based on the information on the user&#39;s taste. Here, information showing that programs to the user&#39;s taste exist refers to an electrical signal indicating whether or not the program selection button is made to emit light, and in the case where there are a number of program selection buttons, an electrical signal including information on which program selection button is made to emit light. 
     Here, operation terminal  3  is formed so as to have numbers corresponding to respective channels of television broadcasts received by broadcast receiving part  5 , and allocates the information on the user&#39;s taste of programs to the user&#39;s taste detected by detection part  10  to numbers corresponding to the respective channels.  FIG. 4  shows a concrete configuration for operation terminal  3 ; that is, operation terminal  24 . In addition,  FIG. 5  is a diagram showing the configuration and illustrating the operation of the below described number buttons for emitting light on operation terminal  24  shown in  FIG. 4 . 
       FIG. 4  shows operation terminal  24 . Operation terminal  24  has POWER button  24   c  for turning on and off the power source, CH button  24   a  for sequentially selecting the channel, VOL button  24   b  for changing the volume, and number buttons  22  from “1” to “12” with which the channel can be directly selected. In addition,  FIG. 5  shows number button  22 . Number button  22  has light source  23  inside, and light source  23  is controlled by operation terminal controlling part  17  shown in  FIG. 1 . Then, light is emitted, when the program corresponding to number button  22  is recommended. In  FIGS. 4 and 5 , number buttons  22  are selection part  21  of  FIG. 1 , and light source  23  is output part  20  of  FIG. 1 . In addition, number buttons  22  can also be a program selection button, not shown in  FIG. 1 . 
     When operation terminal  24  receives the information on the user&#39;s taste, operation terminal controlling part  17  allocates the information on the user&#39;s taste to number button  22  corresponding to the recommended program and instructs the light source inside number button  22  to emit light. When channel  3   ch , for example, is preset to number button  22  “3,” operation terminal controlling part  17  makes light source  23  inside number button  22  “3” emit light, in the case where the information on the user&#39;s taste relates to the program of  3   ch , as shown in  FIG. 4 . 
     Here, though a system for illuminating number buttons  22  with light from light source  23  is shown in  FIG. 5 , the present invention is not limited to this system. Another method according to the present invention is described with reference to  FIGS. 15 and 16 . 
     In  FIGS. 15 and 16 , number button  22  is equipped with display part  229 . Display controlling part  231  is controlled by operation terminal controlling part  17 . Display controlling part  231  controls the contents of display on display part  229  following the instruction from operation terminal controlling part  17 . Display part  229  reflects display  22 DP, for example the name of the broadcasting station, the broadcast program title, the logo of the broadcasting station or the logo of the program, through the control by display controlling part  231 . 
     Here, this display system is not limited to the first embodiment, and can be applied to all embodiments of the present invention. 
     Next, the operation of television system  1  of the present invention is described.

The operation for recommending programs is described with reference to this  FIG. 2 . 
     Using channel table  14 , program recommendation controlling part  9  presets the channels so that the broadcast channels received by television broadcast reception device  2  and the preset numbers for selecting a program used in television broadcast reception device  2  and operation terminal  3  correspond to each other (Step S 0 ). The user inputs information on the user&#39;s taste through input part  13 , and program recommendation controlling part  9  allows the inputted information on the user&#39;s taste to be stored in information on user&#39;s taste storing part  15  (Step S 1 ). 
     Television broadcast reception device  2  receives digital television broadcasts through antenna part  4  (Step S 2 ). The time when the user is viewing a program is calculated by time measuring part  16 . Detection part  10  uses the program information acquired from broadcasts received in Step S 2  and the information on the user&#39;s taste inputted from information on user&#39;s taste storing part  15  to detect a program to the user&#39;s taste from among the programs being broadcast at that time and transmit the information on the user&#39;s taste of the above described program to the user&#39;s taste that is required to select the program to the user&#39;s taste to data transmitting and receiving part  11 . In addition, program recommendation controlling part  9  allows the program information to be stored in program information storing part  12  (Step S 3 ). 
     Program recommendation controlling part  9  allows the information on the user&#39;s taste to be transmitted to operation terminal  3  from data transmitting and receiving part  11  (Step S 4 ). The information on the user&#39;s taste that is transmitted from data transmitting and receiving part  11  in television broadcast reception device  2  in Step S 4  is received by information on user&#39;s taste receiving part  18  in operation terminal controlling part  17  (Step S 5 ). Operation terminal controlling part  17  allocates the information on the user&#39;s taste to number buttons  22  corresponding to the channels of the programs corresponding to the information on the user&#39;s taste received in Step S 5  (Step S 6 ). Operation terminal controlling part  17  makes light source  23  within number button  22  to which the information on the user&#39;s taste is allocated emit light. Here, the method for making light source  23  emit light is merely one display method for operation terminal  3 , and other methods may be used, as long as output part  20  can show that programs to the user&#39;s taste exist in a manner that the user can recognize (Step S 7 ). 
     The operation for recommending programs in television broadcast reception device  2  and operation terminal  3  is described above, and in the case where the user views the recommended program, television system  1  carries out the below described operation for selecting programs (C 1  and C 2 ). At this time, C 1  and C 2  in  FIG. 2  correspond to C 1  and C 2  in  FIG. 3 , respectively. In addition, it is not necessary to preset the channels in Step S 0  and input the information on the user&#39;s taste in Step S 1  every time the above described operation for recommending programs is carried out, but it is possible to freely change these. 
       FIG. 3  is a flow chart showing the operation for selecting programs in television system  1  according to the present invention. The operation for selecting programs is described with reference to this  FIG. 3 . 
     Television broadcast reception device  2  allows broadcast receiving part  5  to receive digital television broadcasts through antenna part  4  (Step S 10 ). Meanwhile, the user selects a desired program through selection part  21  on operation terminal  3 , into which selected program information converted to an electrical signal is inputted. This means that number button  22  having light source  23  which emits light outputting information showing that recommended programs to the user&#39;s taste exist inside is pressed, so that the operation for pressing number button  22  converts the selected program information to an electrical signal, which is then inputted (Step S 8 ). The selected program information that has been converted to an electrical signal and inputted in Step S 8  is controlled by operation terminal controlling part  17  and transmitted to data transmitting and receiving part  11  in television broadcast reception device  2  (Step S 9 ). 
     The selected program information transmitted in Step S 9  is received by data transmitting and receiving part  11  (Step S 11 ). Program recommendation controlling part  9  acquires the channel corresponding to the selected program information received from channel table  14  in Step S 11 . From here, the procedure branches to Step  13 , in which the program information on the selected program is stored as information on the user&#39;s taste, and Step  15 , in which the selected program is decoded (Step S 12 ). Program recommendation controlling part  9  reads out the program information on the program being broadcast on the channel gained in Step S 12  at the time from program information storing part  13  (Step S 13 ). The program recommendation controlling part stores the program information that is read out in Step S 13  in information on user&#39;s taste storing part  15  as information on the user&#39;s taste (Step S 14 ). Meanwhile, the program gained in Step S 12  is decoded in decoding part  7  and outputted by program outputting part  8  (Step S 15 ). 
     As described above, television system  1  according to the present first embodiment transmits information on the user&#39;s taste of the program to the user&#39;s taste to operation terminal  3  from television broadcast reception device  2  and outputs information showing that programs to the user&#39;s taste exist to operation terminal  3 , so that the user can select a program to the user&#39;s taste and the selected program information is transmitted to television broadcast reception device  2 , and thus, the user can view a desired program. As described above, two-directional communication between television broadcast reception device  2  and operation terminal  3  is possible, so that television broadcast reception device  2  can transmit information on the user&#39;s taste to operation terminal  3 , and operation terminal  3  can transmit selected program information to television broadcast reception device  2 , and thus, it becomes possible to see programs to the user&#39;s taste on operation terminal  3 , and it becomes possible to view a program to the user&#39;s taste with a simple operation. 
     In addition, unlike the prior art, the television system according to the first embodiment is not so complicated that a list of recommendations is displayed on the screen, from which a program is selected, and thus, no complicated operation on the operation terminal is required. Therefore, the user can smoothly operate the operation terminal and it is not necessary to select a program to the user&#39;s taste on the screen, and therefore, it can be easily known by looking at the operation terminal that a program to the user&#39;s taste is being broadcast, so that the program can be selected. In addition, according to the prior art, a list of recommendations is displayed on the screen so that a recommended program can be selected, and therefore, it is difficult to view broadcast images on the television while the list of recommendations is displayed. According to the present invention, however, information showing that programs to the user&#39;s taste exist is outputted to the operation terminal, and thus, no list of recommendations or the like is displayed on the television screen, and therefore, the user can be informed that recommended programs to the user&#39;s taste exist while viewing broadcast images on the television. Furthermore, according to the present invention, the television system automatically outputs and displays information showing that programs to the user&#39;s taste exist for the user, and in addition, the information showing that programs to the user&#39;s taste exist is outputted to the operation terminal, and therefore, the user is not prevented from viewing the television. 
     In addition, the information on the user&#39;s taste on the programs to the user&#39;s taste is allocated to numbers (number buttons) corresponding to the respective channels on operation terminal  24 , and thus, pieces of information on the user&#39;s taste and portions of selection part  21  correspond one-to-one on operation terminal  24 , so that conventionally used buttons for selecting programs which are not recommended programs can be used as selection part  21  for recommended programs. Therefore, in order to view a recommended program to the user&#39;s taste, a program to the user&#39;s taste can be selected through one-time operation for selecting a program; that is, by pressing a number button, in the same manner as for conventional selection of a program by pressing a number button once. 
     This corresponds to conventional methods for recommending a program according to which the user displays a list of recommendations on the screen in the case where there are recommended programs, and the user sees which programs are recommended programs on the screen, and after that, moves the selection cursor in the list of recommendation for selection, in order to select a program to be viewed, and then, views a recommended program. Therefore, a number of complicated operations are necessary. In contrast, according to the present embodiment, light source  23  within number button  22 , which is the output part, emits light in the case where there is a recommended program, and thus, information showing that programs to the user&#39;s taste exist is automatically outputted to operation terminal  3 , and the user can see which channel is for a recommended program on operation terminal  3  and presses the number button that is emitting light, and thus, a recommended program can be viewed. That is to say, the required operation is simple pressing down of the number button emitting light, and therefore, there is no operation for displaying a list of recommendations on the screen or selecting a program from the list of recommendations. Furthermore, in the configuration where number buttons  22  emit light, output part  20 , selection part  21  and buttons for conventionally selecting programs are integrated, and therefore, a program to the user&#39;s taste can be selected through on-time operation for selecting a program, in the same manner as in the operation for conventionally selecting a program by pressing a number button which is emitting light. 
     Second Embodiment 
     Next, the second embodiment of the present invention is described with reference to  FIGS. 10 and 11 . In this second embodiment, as shown in  FIG. 10 , television system  1  is further provided with determination part  101  for determining the degree of the user&#39;s taste for different programs in the configuration of television system  1  of the first embodiment, in the case where a number of programs to the user&#39;s taste are recommended. Detection part  10  detects a number of programs to the user&#39;s taste, information on the user&#39;s taste received by data transmitting and receiving part  11  is information on the user&#39;s taste for a number of programs to the user&#39;s taste, operation terminal  3  receives information on the user&#39;s taste for a number of programs to the user&#39;s taste, and output part  20  outputs information showing that a number of programs to the user&#39;s taste exist based on the received information on the user&#39;s taste, so that information showing the respective programs to the user&#39;s taste exist is in different formats. 
     As shown in  FIG. 11 , the second embodiment is provided with determination part  101  within detection part  10  in television broadcast reception device  2  of  FIG. 1 . In addition, determination part  101  is controlled by program recommendation controlling part  9 . Here, descriptions of parts in the configuration which are the same as those in the first embodiment are omitted. Here, output of information showing that different programs exist in different formats means that there are a number of program selection buttons which are the same as that described in the first embodiment, and when the program selection buttons emit visual light for output of the information, the color of light emitted from the program selection buttons varies, so that light emitted from the program selection buttons has variation. In the second embodiment, information showing that programs to the user&#39;s taste exist refers to an electrical signal indicating which program selection buttons emit light in what manner. 
     Here, variation in the color of emitted light means variation in the color of emitted light in accordance with the degree of the user&#39;s taste for programs, use of gradation by intensifying and weakening the emitted colored light, or emission of light having a special color, in the case where the information on the user&#39;s taste for the recommended programs is urgent information. In addition, in the case where a number of programs to the user&#39;s taste are recommended in operation terminal  24 , a number of channels are recommended, and therefore, operation terminal controlling part  17  allocates information on the user&#39;s taste to the number buttons corresponding to the channels of the respective programs that are recommended. Thus, operation terminal controlling part  17  allows the light sources inside the respective number buttons to emit different light in accordance with the degree of the user&#39;s taste for the programs. 
     Next, the operation of determination part  101  for determining the degree of the user&#39;s taste for programs is described. Detection part  10  detects programs to the user&#39;s taste based on program information at the time and information on the user&#39;s taste. Here, as an example of the operation of determination part  101 , a case can be cited where the method for determining the degree of the user&#39;s taste for programs in the determination part is a determination method through matching between respective elements of information on the user&#39;s taste and the program information. At this time, information on the user&#39;s taste is made up of five elements: program title, genre, start time, finish time and keywords for programs. In addition, program information on the respective programs is also made up of five elements: program title, genre, start time, finish time and keywords for programs. In addition, in determining the user&#39;s taste, elements are matched between information on the user&#39;s taste and information on the user&#39;s taste for different programs. In addition, in the second embodiment, the number of elements where the values coincide as a result of matching between the program information on different programs and the information on the user&#39;s taste is regarded as the degree of the user&#39;s taste for programs. 
       FIG. 9  shows the results of matching for different programs.  FIG. 9  is a matrix diagram with programs in the lateral direction and information on the user&#39;s taste in the longitudinal direction. “Y” in  FIG. 9  indicates that the value of the element of information on the user&#39;s taste and the value of the element of program information are the same, and “N” indicates that they are not the same. As shown in  FIG. 9 , the degree of the user&#39;s taste for program A is 4, the degree of the user&#39;s taste for program B is 2, the degree of the user&#39;s taste for program C is 1, the degree of the user&#39;s taste for program D is 5, and the degree of the user&#39;s taste for program E is 0. 
     In addition, it is assumed that detection part  10  detects programs to the user&#39;s taste using the degree of the user&#39;s taste for programs. According to this method, detection part  10  uses a predetermined threshold value to detect programs having the threshold value or higher as a program to the user&#39;s taste. Here, in the case where the threshold value is 3, program A of which the degree of the user&#39;s taste for the program is “4” and program D of which the degree of the user&#39;s taste for the program is “5” are detected as programs to the user&#39;s taste, from among programs A to E in  FIG. 9 . In addition, the degree of the user&#39;s taste for the detected programs to the user&#39;s taste may also be used as one piece of information on the user&#39;s taste when output part  20  shows that programs to the user&#39;s taste exist. In this example, a number of programs to the user&#39;s taste are detected, and therefore, output part  20  must have different expressions to show that programs to the user&#39;s taste exist when showing that a number of programs to the user&#39;s taste exist. At this time, it is shown that programs to the user&#39;s taste exist using the degree of the user&#39;s taste for programs. In the case where the method for showing that programs to the user&#39;s taste exist is to make output part  20  emit light, it is possible for operation terminal controlling part  17  to intensify or weaken the emitted colored light through gradation in accordance with the degree of the user&#39;s taste for programs, or to emit red, yellow and blue light in the order of the degree of the user&#39;s taste, from highest to lowest. 
     As described above, the television system according to the second embodiment is provided with determination part  101  for determining the degree of the user&#39;s taste for programs, and the output of output part  20  is different for different programs to the user&#39;s taste in the case where a number of programs to the user&#39;s taste are detected. In this manner, the degree of the user&#39;s taste for different programs is determined, and this is used for the detection of programs to the user&#39;s taste. In addition, the recommendations to the user can be ordered using the degree of the user&#39;s taste for programs, and therefore, operation terminal  3  outputs information showing that a number of programs to the user&#39;s taste exist. Thus, the output has different formats using the above described order for recommendation, in order to show that different programs to the user&#39;s taste exist, and the user can easily see the difference between the number of outputted programs to the user&#39;s taste. Here, use of determination part  101  for determining the degree of the user&#39;s taste for programs is not limited to when a number of programs to the user&#39;s taste are recommended, and it is possible to use determination part  101  when one program to the user&#39;s taste is recommended. 
     Third Embodiment 
     In the configuration of operation terminal  24 , as shown in  FIGS. 4 and 5 , in television system  1  according to the first and second embodiments, it is in some cases difficult to select a program. In the case where the number of channels is great, as with cable television, for example, the number of number buttons on operation terminal  3  for selecting a program is limited. Accordingly, the number of buttons is not sufficient, and in some cases, it is impossible to make one-to-one correspondence between buttons and channels. Therefore, in the third embodiment of the present invention, the manner in which correspondence is made between number buttons and channels on the operation terminal is shown, in the case where the number of broadcast channels is greater than that of the number buttons for the operation of selecting a program as described above. 
     The third embodiment is described in accordance with  FIGS. 6 and 8 . Here, descriptions for parts of the configuration which are the same as in the first and second embodiments are omitted. 
     Remote controls (operation terminal) for cable television have number buttons for selecting a program in ten-key form, and when a channel is selected, a numeral value is inputted for each digit of the number of a channel, by pressing ten keys. When the program of channel  35   ch  is desired to be viewed, for example, the user presses number button  223   a   0  “3,” so that the digit of tens is determined, and subsequently presses number button  225   a  “5,” so that the digit of ones is determined. The following is possible as a method for outputting information showing that programs to the user&#39;s taste exist in the third embodiment using an operation terminal as that described above. Appearance of remote control  3   a   0  and appearance of remote control  3   a   1  in  FIG. 6 , for example, show that channel  35   ch  is a program to the user&#39;s taste when information to the user&#39;s taste received by the operation terminal is information on the user&#39;s taste for channel  35   ch.    
     Appearance of remote control  3   a   0  and appearance of remote control  3   a   1  in  FIG. 6  show number buttons “0” to “9” used for selecting programs, and the respective number buttons are formed so as to emit light when operation terminal controlling part  17  allocates information on the user&#39;s taste to the respective number buttons. First, number button  223   a   0  “3” emits light, and number button  223   a   0  “3,” which is emitting light, is selected by the user, and then, number button  225   a   1  “5” emits light. Then, when number button  225   a   1  “5” is selected, the program being viewed is switched to channel  35   ch . This is a method for outputting information showing that a program to the user&#39;s taste exists in the case of multiple channels, for example with cable television according to which number buttons emit light in sequence, letting the user know how to navigate. 
     In addition, this method can be used in the case of a multi-tuner which can receive terrestrial wave digital broadcasts, terrestrial wave analog broadcasts, BS broadcasts and CS broadcasts. Appearance of remote control  3   b   1  and appearance of remote control  3   b   2  in  FIG. 6  show the operation of operation terminal  3  at this time. Appearance of remote control  3   b   0  and appearance of remote control  3   b   1  in  FIG. 6  show terrestrial wave A button  22 TA, terrestrial wave D button  22 TD, BS button  22 BS and CS button  22 CS for switching the type of broadcast waves, and number buttons “1” to “12” for selecting the channel of each type of broadcast wave. Terrestrial wave A button  22 TA is a button for terrestrial wave analog broadcast, terrestrial wave D button  22 TD is a button for terrestrial wave digital broadcast, BS button  22 BS is a button for BS broadcast, and CS button  22 CS is a button for CS broadcast. In addition, terrestrial wave A button  22 TA, terrestrial wave D button  22 TD, BS button  22 BS, CS button  22 CS and number buttons “1” to “12” are formed so as to emit light when operation terminal controlling part  17  allocates information on the user&#39;s taste. A case is assumed where, for example, when a terrestrial wave digital broadcast is being viewed, channel  5   ch  of BS broadcast is recommended as a program to the user&#39;s taste. First, BS button  22 BS emits light (see appearance of remote control  3   b   0  in  FIG. 6 ), and BS button  22 BS, which is emitting light, is selected by the user, and then, number button  225   b   1  “5” emits light (see appearance of remote control  3   b   1  in  FIG. 6 ). Then, when number button  225   b   1  “5” is selected, the program being viewed is switched to channel  5   ch  of BS broadcast. 
     As described above, the configuration allows buttons to emit light in the order in which the user should select, and thus, operation terminal  3  allows the user to navigate the operation for selecting a program, in such a manner that a sequential operation for selecting a program which is the same as in the prior art allows the program to the user&#39;s taste to be viewed. 
     Next, appearance of remote control  3   c   0  and appearance of remote control  3   c   1  in  FIG. 6  show the manner in which correspondence is made between number buttons and channels in accordance with a different method from the above described method in the case where the number of channels is great. In the case where there are many channels, as with the above described cable television, and the number of buttons is insufficient, as shown in appearance of remote control  3   c   0  and appearance of remote control  3   c   1 , number buttons “0” to “9” and tuning mode switching button  22 MS for switching between the below described normal tuning mode and the below described direct tuning mode are added in the configuration. In addition, the number buttons “0” to “9” and tuning mode switching button  22 MS are formed so as to emit light when operation terminal controlling part  17  allocates information on the user&#39;s taste. 
     In normal tuning mode, selection of buttons is carried out a number of times in order to view a program, in the same manner as in the tuning method for cable television. In the case where a program on channel  35   ch , for example, is viewed, channel  35   ch  is selected in accordance with a method for selecting number button  223   c   0  “3” and then selecting number button  225  c 1  “5,” so that the program can be viewed. In direct tuning mode, a number button is selected only once, so that the program on the channel corresponding to the number button that has been preset in advance can be viewed. When switched to direct tuning mode, television system  1  switches the program using channel table  14  for direct tuning mode in  FIG. 8 . 
       FIG. 8  shows the relationship between channels  14   ad  and preset numbers  14   bd  in direct tuning mode. Channel  8   ch  corresponds to the preset number “1” (number button “1”), channel  10   ch  corresponds to the preset number “2” (number button “2”), channel  52   ch  corresponds to the preset number “3” (number button “3”), channel  64   ch  corresponds to the preset number “4” (number button “4”), channel  49   ch  corresponds to the preset number “5” (number button “5”), channel  51   ch  corresponds to the preset number “6” (number button “6”), and channel  11   ch  corresponds to the preset number “7” (number button “7”). Here, the preset numbers “8,” “9” and “0” are not yet set so as to correspond to channels. 
     Here, in the case where channel  49   ch  is recommended as a program to the user&#39;s taste, channel  49   ch  is in channel table  14  in direct tuning mode, and therefore, tuning mode switching button  22 MS emits light (see appearance of remote control  3   c   0  in  FIG. 6 ). When running mode switching button  22 MS, which is emitting light, is selected, next, number button  225   c   1  “5” emits light (see appearance of remote control  3   c   1  in  FIG. 6 ). Then, when number button  225   c   1 , which is emitting light, is selected, channel table  14  in direct tuning mode is used to switch the program being viewed to the program on channel  49   ch.    
     As described above, tuning mode switching button  22  MS is provided on the operation terminal, and channel table  14  in direct tuning mode is used, so that information on the user&#39;s taste for programs to the user&#39;s taste is allocated to the corresponding number buttons on the operation terminal. As a result, one-to-one correspondence can be made between pieces of information on the user&#39;s taste and portions of selection part  21 , even in the case of multiple channels, by switching the tuning mode, so that a program can be selected through one-time operation for selecting a program in order to view a recommended program to the user&#39;s taste. 
     Here, channels in channel table  14  in direct tuning mode, which is used when the mode is switched to direct tuning mode, may be preset by the user, or the television broadcast reception device may automatically allocate the channels in the configuration. In the case where the television system is provided with determination part  10   a  for determining the degree of the user&#39;s taste for different programs, television broadcast reception device  2  allocates preset numbers in sequence starting from the channel for the program to the user&#39;s taste having a high degree of the user&#39;s taste for the program which has been determined by determination part  10   a . Concretely, when the channels for the recommended programs to the user&#39;s taste are  1   ch ,  3   ch ,  5   ch ,  11   ch ,  25   ch  and  35   ch , it is assumed that the degree of the user&#39;s taste for the programs broadcast on these channels is higher in the order of  1   ch ,  11   ch ,  35   ch ,  5   ch ,  25   ch ,  3   ch . In this case, the television broadcast reception device automatically presets the numbers in such a manner that the television broadcast reception device makes  1   ch ,  11   ch ,  35   ch ,  5   ch ,  25   ch  and  3   ch  correspond to the preset number “1,” the preset number “2,” the preset number “3,” the preset number “4,” the preset number “5” and the preset number “6,” respectively. 
     As described above, tuning mode switching button  22 MS is provided in the configuration, so that buttons emit light in the order for the user to select, and thus, operation terminal  3  allows the user to navigate the operation for selecting a program, so that a program to the user&#39;s taste can be viewed through a sequential operation for selecting a program. 
     Fourth Embodiment 
     The fourth embodiment is described with reference to  FIGS. 11 and 12 . The fourth embodiment is provided with location change detecting part  301  for detecting change in the location of operation terminal  3 , in addition to the configuration of television system  1  according to the first to third embodiments, in order to recommend programs to the user&#39;s taste to the user with appropriate timing. When change in the location is detected, operation terminal  3  transmits a signal indicating that change in the location of operation terminal  3  has been detected to television broadcast reception device  2 . Thus, television broadcast reception device  2  is formed so as to detect programs to the user&#39;s taste when it receives the signal and allow output part  20  of operation terminal  3  to output information showing that programs to the user&#39;s taste exist. Here, descriptions for parts of the configuration that are the same as in the first to third embodiments are omitted. The operation of this configuration is described below. 
     In the case where location change detecting part  301  of operation terminal  3  detects change in the location of operation terminal  3 , operation terminal controlling part  17  informs television broadcast reception device  2  of the change in the location of operation terminal  3 . Then, when program recommendation controlling part  9  in television broadcast reception device  2  learns of the change in the location of operation terminal  3 , it starts recommending the programs to the user&#39;s taste. 
     Separately from this, as shown in  FIG. 12 , television system  1  is formed in such a manner that when the power of television broadcast reception device  2  is turned on, information showing that programs to the user&#39;s taste exist is outputted. Here, the other parts in the configuration are the same as in the first to third embodiments. In accordance with the operation of this configuration, power ON detecting part  302  detects turning ON of the power when the power of television broadcast reception device  2  is turned on. As a result of this detection, program recommendation controlling part  9  starts recommending programs to the user&#39;s taste. Here, the power may be turned on through operation of operation terminal  3 , or the power may be turned on directly on television broadcast reception device  2 . 
     As described above, the television system according to these embodiments is formed so as to detect change in the location of operation terminal  3  and allow output part  20  to output information showing that programs to the user&#39;s taste exist when change is detected. In addition, when the power of television broadcast reception device  2  is turned on, information showing that programs to the user&#39;s taste exist is outputted in the configuration. This is in order to make it possible to recommend programs to the user with such timing that the probability of the user zapping the channel in order to determine the program to be viewed when the user picks up operation terminal  3  or the user starts viewing television. As a result, programs to the user&#39;s taste can be recommended to the user with appropriate timing. 
     Fifth Embodiment 
     The fifth embodiment is described with reference to  FIG. 12 . This fifth embodiment is formed in such a manner that output part  20  stops outputting information showing that programs to the user&#39;s taste exist when a program to the user&#39;s taste is selected in the case where output part  20  outputs information showing that programs to the user&#39;s taste exist in the configuration of television system  1  according to the first to fourth embodiments, in order to reduce the power consumed by operation terminal  3 . In the case where a program is selected through selection part  21  when output part  20  is outputting information showing that programs to the user&#39;s taste exist, operation terminal controlling part  17  instructs output part  20  to stop outputting. Here, descriptions for parts in the configuration that are the same as in the first to fourth embodiments are omitted. 
     In addition, in another possible configuration according to the present embodiment, output part  20  stops outputting information showing that programs to the user&#39;s taste exist in the case where no program to the user&#39;s taste is selected for a predetermined period of time or longer after output part  20  outputs information showing that programs to the user&#39;s taste exist. In this configuration, time measuring part  16  in television broadcast reception device  2  has a timer function and the timer is started at the point in time when program recommendation controlling part  9  recommends operation terminal  3  programs to the user&#39;s taste. Then, when the timer exceeds a predetermined period of time (for example 5 minutes), program recommendation controlling part  9  instructs operation terminal controlling part  17  in operation terminal  3  to stop output part  20 , and stops and resets the timer. In addition, in the case where a program is selected within the predetermined period of time and data transmitting and receiving part  11  receives selected program information, the timer is stopped by program recommendation controlling part  9  and reset. 
     As described above, in the television system according to these embodiments, output part  20  stops outputting information showing that programs to the user&#39;s taste exist when a program to the user&#39;s taste is selected by selection part  21  in the case where output part  20  outputs information showing that programs to the user&#39;s taste exist. In addition, in the case where no program to the user&#39;s taste is selected when a predetermined period of time or longer has elapsed after output part  20  outputs information showing that programs to the user&#39;s taste exist, output part  20  stops outputting information showing that programs to the user&#39;s taste exist. As a result, a situation where information showing that programs to the user&#39;s taste exist continues being outputted can be avoided, and the power consumed by operation terminal  3  can be reduced by stopping the output. In addition, a configuration where output part  20  does not output information showing that programs to the user&#39;s taste exist in the case where the program viewed by the user at the time is a program to the user&#39;s taste can also gain the effects of reducing the consumed power, in the same manner as the above described configuration. 
     Sixth Embodiment 
     The sixth embodiment is described with reference to  FIG. 13 . In the sixth embodiment, the power consumed by television broadcast reception device  2  is reduced. In order to do so, part for detecting whether programs are the same  203  determines whether or not the program to the user&#39;s taste detected by detection part  10  in television broadcast reception device  2  and the program outputted by program outputting part  8  at the time are the same in the configuration of television system  1  according to the first to fifth embodiments. In the case where it is determined that the program to the user&#39;s taste and the program outputted by program outputting part  8  are the same, data transmitting and receiving part  11  stops transmitting information on the user&#39;s taste for the programs to the user&#39;s taste detected by detection part  10  to operation terminal  3  in the configuration. Here, descriptions for parts in the configuration that are the same as in the first to fifth embodiments are omitted. 
     In the television system having the above described configuration according to the present embodiment, television broadcast reception device  2  does not transmit information on the user&#39;s taste to operation terminal  3  in the case where the program being viewed by the user and the detected program to the user&#39;s taste are the same, and therefore, the power consumed by television broadcast reception device  2  can be reduced. Furthermore, operation terminal  3  does not receive information on the user&#39;s taste, and therefore, output part  20  does not output information showing that programs to the user&#39;s taste exist, and thus, the power consumed by operation terminal  3  can also be reduced. 
     Seventh Embodiment 
     The seventh embodiment is described with reference to  FIG. 14 . In the seventh embodiment, programs to respective users&#39; tastes are recommended to the users in the case where the television is shared by a number of users. In order to do so, television system  1  has user identifying part  204  for identifying the user in the configuration of television system  1  according to the first to sixth embodiments. Output part  20  is formed so as to output information showing that programs to the identified user&#39;s taste exist. Here, descriptions for parts in the configuration that are the same as in the first to sixth embodiments are omitted. 
     The present embodiment identifies different users and provides information on the different users&#39; tastes, and thus, information on users&#39; tastes is stored in different regions in information on user&#39;s taste storing part  15  in advance for different users. Thus, user identifying part  204  may switch the information on the user&#39;s taste when it identifies information on individuals using identification numbers or through confirmation of fingerprints, or a button for switching the user may be prepared on operation terminal  3  or television broadcast reception device  2 . Here, switching of the user means switching of the information on the user&#39;s taste. Through this operation, the user is identified and the information on the identified user&#39;s taste is stored in a different region in information on user&#39;s taste storing part  15 , so that detection part  10  can detect programs to the user&#39;s taste based on the information on the identified user&#39;s taste. 
     As described above, the television system according to the present embodiment has user identifying part  204  for identifying the user, and output part  20  outputs information showing that programs to the identified user&#39;s taste exist. This is in order to make it possible to recommend programs to the taste of the user viewing the television at the time in the case where programs are recommended to one of a number of users, for example family members who share one television, and which user is viewing the television is not always determined. As a result, even in the case where a television is shared by a number of users, programs to different users&#39; tastes can be recommended. 
     Here, operation terminal  3  may have a function of detecting programs to the user&#39;s taste based on program information and information on the user&#39;s taste, instead of television broadcast reception device  2 . When operation terminal  3  has this function, it becomes unnecessary to transmit information on the user&#39;s taste from television broadcast reception device  2  to operation terminal  3  in order to recommend programs to the user&#39;s taste on operation terminal  3 , and programs to the user&#39;s taste can be recommended on the operation terminal even in a television broadcast reception device where programs are not recommended as in the present embodiment. 
     In addition, television broadcast reception device  2  according to the above described embodiment may be formed so that information on the user&#39;s taste can be transmitted using an electrical communication line, for example the internet, and operation terminal  3  can be made to receive television broadcasts and display this on a screen, like cellular phones. In the case of a configuration where the system can be connected to an electrical communication line, for example the internet, information on the user&#39;s taste that is transmitted from television broadcast reception device  2  using the electrical communication line is acquired by operation terminal  3  using the electrical communication line. Thus, information showing that programs to the user&#39;s taste exist is outputted based on the received information on the user&#39;s taste, and an outputted and recommended program to the user&#39;s taste is selected, so that the selected program to the user&#39;s taste can be displayed on the screen of the operation terminal  3  and viewed. In this manner, the present television system transmits information on the user&#39;s taste using an electrical communication line, for example the internet, so that a program to the user&#39;s taste can be viewed through a simple operation. 
     In addition, though the received television broadcasts are digital television broadcasts in the above described embodiments, analog television broadcasts may be received, or different types of broadcasts, such as terrestrial wave broadcasts, or satellite broadcasts, may be received, as long as the configuration allows for implementation of the present invention. 
     In addition, it is also possible for operation terminal  3  to have the same table as channel table  14  in television broadcast reception device  2  according to the first to seventh embodiments. Thus, the channel corresponding to the button selected by the user can be detected on the operation terminal, and the detected channel can be transmitted to data transmitting and receiving part  11  in television broadcast reception device  2  as information on the user&#39;s taste, so that it becomes possible to view the program to the user&#39;s taste without any steps for finding the channel using channel table  14  in television broadcast reception device  2 . 
     In addition, output part  20  for outputting information showing that programs to the user&#39;s taste exist may be able to show that programs to the user&#39;s taste exist according to the above descried embodiments. Accordingly, the method is not limited to one for illuminating program selection buttons, and which programs are programs to the user&#39;s taste and which selection buttons should be pressed may be shown to the user through speech sound or the like, and any apparatus which can show that programs to the user&#39;s taste exist in such a manner that the user can see this on operation terminal  3  may be used. That is to say, in the case where it is shown that programs to the user&#39;s taste exist through speech sound, the information showing that programs to the user&#39;s taste exist refers to a speech sound signal which is outputted through speakers for outputting speech sound or the like, and indicates which programs are programs to the user&#39;s taste and which selection buttons should be pressed. In the case where it is shown that programs to the user&#39;s taste exist through a speech sound or the like as described above, it is not necessary for selection part  21  to have output part  20  like in  FIGS. 1 and 5 , and selection part  21  and output part  20  may be arranged separately on operation terminal  3 . 
     In addition, a display may be arranged on operation terminal  3 , so that the display can show that programs to the user&#39;s taste exist. In this case, information showing that programs to the user&#39;s taste exist refers to an electrical signal indicating text information which shows which programs are programs to the user&#39;s taste and which selection buttons should be pressed. 
     INDUSTRIAL APPLICABILITY 
     The television system, the broadcast reception device and the operation terminal according to the present invention allow the user to be easily informed that a program to the user&#39;s taste is being broadcast when the user looks at the operation terminal, and it becomes possible to select the program, and therefore, are useful as a means for recommending programs to the user&#39;s taste.
