## Abstract

Information relating to print contents is presented to the user in an easily understandable manner. A demultiplexer separates picture data, speech data and other data from received data. Such data include EPG data, data broadcast data, print contents data and supplementary information on the print contents data. A data stream process unit decodes the supplementary information on the print contents data and the print contents data. An image construction unit constructs an image signal of an image frame, providing a list display of transmission schedule and supplementary information of the print contents. The image signal is supplied through a display controller to an image display unit and displayed as an image.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a data processing apparatus and a system in a television broadcasting receiver which supports data broadcasting reception for receiving data broadcast contents multiplexing, for example, a character, an image, a speech, a picture and the like and executing display and reproduction.
2. Related Background Art
Data broadcasting is now operated in the ground wave television broadcasting, and is going to be operated also in the satellite digital broadcasting. Such data broadcasting is broadcast from a broadcasting station by superposing data with a broadcasting wave. A receiving terminal fetches the received and accumulated data into a personal computer or an exclusive terminal, and a display is given by a general WWW (world wide web) browser software or an exclusive browser software.
Recently, new services are anticipated by rendering such data broadcasting receivable not only in a personal computer but also in a television receiver. By providing the television receiver itself with a data broadcast receiving function and a browser software, even a user not having a personal computer can easily view the information of the data broadcasting, thereby enjoying a service of displaying information relating to the television program by characters and image.
As an example, a novel news service utilizing the data broadcasting is proposed. In such service, a picture of a news is recorded in advance in an accumulating apparatus of a television receiver, then a data broadcasting image composed of characters and image is presented as “a news item” to the user, and a picture of a news item selected by the user, for example by a remote control, is reproduced. Such service allows the user to observe, at any time, a news program that has been available only at predetermined times, and allows the user to observe the desired news items only. In this manner, novel services that have not existed become available. Reference is to be made, for example, to Japanese Patent Application Laid-open No. 2001-285815 (US AA2002016964).
In case the television receiver is given a receiving function for such data broadcasting, a font of a somewhat larger size is usually employed for improving the legibility of characters. As a result, an amount of character information that can be displayed at a time is naturally reduced. For example, in a news service, only three to five news contents can be displayed at maximum on an image area, and it is difficult to display many news items in summary and with photographs.
It is possible to display the information that cannot be displayed at one time by scrolling or by page switching, but this requires the user to execute an unnecessary operation. Such operation cannot be considered adequate, in consideration of the user who is not accustomed with an operation environment of a personal computer or a video game machine.
Also the convenience to the user can be improved by printing useful contents of the broadcasted picture program or the data broadcasting on a paper for reviewing afterwards. In such case, it is conceivable to connect a video printer to the television receiver and to capture and print an image displayed on the television receiver. However, since a larger font is usually used for increasing the legibility of the characters, the printed characters become inevitably large. In such case, it is not possible to exploit the advantage of paper that generally has a higher character legibility than in a television image.
Data printing of data broadcasting is described in patent references 1 to 7. Also a technology including print data in the data broadcasting is described in patent reference 8.

In order to resolve such drawbacks, it is also conceivable to broadcast, together with the data of picture-speech program or the data of data broadcasting, printable data such as more detailed character data and image data as a transport stream (TS) and to use such data for printing with a printer as a peripheral equipment. In such case, following drawbacks are encountered.
Firstly, it is difficult for the user to judge when the printing data are transmitted and until when the data is printable. Secondly, it is difficult for the user to judge the contents of the transmitted printing data. Thirdly, it is difficult for the user to understand the type of the transmitted printing data. Fourthly, it is difficult for the user to estimate the volume of printing. Fifthly, it is difficult for the user to judge whether the printing is charged or not. Sixthly, it is difficult for the user to judge the printing time required by the printer connected to the receiver. Seventhly, it is difficult for the user to judge whether the transmitted data can be accumulated. Eighthly, it is difficult for the user to judge, in case the printing data are related with a picture-speech program or a data broadcasting, the picture-speech program or the data broadcasting to which the printing data are related.
In consideration of the foregoing, the present invention is to provide a data receiving-processing apparatus capable of a list display of contents data that can be outputted to a peripheral equipment. The peripheral equipment may be separated from the television receiver or may be integrally incorporated therein.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
In the following, embodiments of the present invention will be explained in detail with reference to accompanying drawings.
Embodiment 1
FIG. 1 is a schematic block diagram of a digital television receiver 100 constituting a first embodiment of the present invention.
A signal received by an unillustrated antenna is entered into a tuner 101. The tuner 101 demodulates the entered signal, and executes a process such as error correction to generate a digital data in a format called transport stream. The generated transport stream (TS) data are inputted into a descrambler 102.
In case the TS data, scrambled for audio-visual restriction, are entered from the tuner 101, the descrambler 102 executes a descrambling based on descrambling key information generated in an IC card controller 117, and outputs the data to a demultiplexer 103. The IC card controller 117 has an IC card containing contract information of a user and key information for descrambling key information contained in the TS data. Also in case the non-scrambled TS data are entered from the tuner 101, the descrambler 102 outputs such data, without change, to the demultiplexer 103.
In the TS data outputted from the descrambler 102, picture data and speech data of plural channels, electronic program guide (EPG) data, data of data broadcasting, printing contents data, supplementary information data relating thereto, etc., are time-sharing multiplexed.
The demultiplexer 103 separates, from the TS data outputted from the descrambler 102, picture data D1 and speech data D2 of a channel selected by an operation unit 114 or a remote control 116, and data D3 constituted of electronic program guide (EPG) data, data of data broadcasting, printing contents data, and supplementary information data relating thereto.
FIG. 2 is a view showing the function of the demultiplexer 103 for separating the picture data D1, the speech data D2, and the data D3 constituted of electronic program guide (EPG) data, data of data broadcasting, printing contents data, and supplementary information data relating thereto.
201 indicates TS data in which picture and speech data of plural channels, EPG data, data broadcasting data, printing contents data, and supplementary information data relating thereto are time-sharing multiplexed. The TS data 201 are transmitted in the unit of a packet represented by TSP in FIG. 2, and, in a header 202 of the TS packet TSP, a packet identifier PID is provided.
The demultiplexer 103, utilizing a PID filter 204 and a section filter 205, extracts PSI (program specific information) information 206 in a payload 203 of a specified TS packet and sends it to a data stream process unit 106. The PSI information defines the content of the entire TS data. Utilizing such information, the demultiplexer 103 extracts the picture data D1 and the speech data D2 of the designated channel, and sends them respectively to a video decoder 104 and an audio decoder 105. The demultiplexer 103 sends, by a similar process, the data broadcast data and the print contents data to the data stream process unit 106.
The demultiplexer 103, utilizing a PID filter 204 and a section filter 205, further extracts EPG data 208 and supplementary information 209 on the printing contents in the payload 203 of the specified TS packet and sends them to the data stream process unit 106.
Processing on the picture data D1 will be explained. The video decoder 104 executes an MPEG2 decoding on the picture data D1 entered from the demultiplexer 103, and outputs the decoded picture data on a display controller 109. The display controller 109 causes an image display 112 to display the output image of the video decoder 104, under switching of an image or superposing of another image and/or characters in response to an operation of the video decoder 104 or the remote control 115. An image construction unit 108 will be explained later. The image display 112 is provided with an image monitor and a picture signal input terminal.
Processing on the speech data D2 will be explained. The audio decoder 105 executes an MPEG2 decoding on the speech data D2 entered from the demultiplexer 103, and outputs the decoded speech data to a speech controller 110. The speech controller 110 converts the speech data entered from the audio decoder 105 into an analog signal and outputs it to a speech output unit 113, which is provided with a speaker and a speech signal input terminal.
In the following there will be explained processing on the data D3 constituted of the electronic program guide (EPG) data, the data broadcasting data, the printing contents data, and the supplementary information data relating thereto.
The EPG data are transmitted, for example, in a data structure defined by a standard “program arrangement information to be used for digital broadcasting” of Association for Regulation for Information Broadcasting (ARIB). It principally includes a TDT (time description table) or a TOT (time offset table) transmitting current time information, an SDT (service description table) transmitting information on a channel such as a name of the channel and a title of a broadcasting industry, and an EIT (even information table) transmitting program information on a title of the program, a date and time of start of broadcasting, and an explanation on the content. The TDT or TOT information is also used for a time display on the receiver 100 and a time management for program reservation.
The data broadcast data are transmitted in repetition from the broadcasting station, by a DSM-CC data carousel method defined in ISO/IEC 13818-6 and ARIB technical data “Regulation for operation of BS digital broadcasting”. The data broadcast data separated by the demultiplexer 103 are constituted of text information, script information, image information and picture/speech data, and are described by XML (extensible markup language) defined in W3C.
The data stream process unit 106 decodes the text information and the image information contained in the EPG data, also decodes the text information, the image information and the picture/speech data contained in the data broadcast data, and enters the obtained data into a memory 107 through a bus 120. A CPU 118, after a process to be explained later on the data broadcast data, stores data, obtained by such process and including display XML data, in the memory 107.
The CPU 118 reads the EPG display data and the XML display data from the memory 107 according to a data broadcast displaying instruction from the operation unit 114 or from the remote control 116 through a light receiving portion 115, and outputs them to an image constructing portion 108.
The image constructing unit 108 outputs, to a display controller 109, a picture signal based on the EPG display data and the XML display data process and outputted by the CPU 118. The display controller 109 outputs a picture signal corresponding to the switching and synthesized display of a picture frame, an EPG display frame and a data broadcast frame to the image display 112.
The bus 120 is further connected to an IEEE1394 interface (I/F) 122 and a modem 122. The IEEE1394 interface (I/F) 122 is used for a protocol communication and data exchange with a printer 132 connected to the receiver 100. The modem 121 is used for an internet connection through an unillustrated telephone line.
FIG. 3 is a plan view of the remote control 116. However, FIG. 3 principally illustrates operation buttons required for realizing functions of the present embodiment, and buttons required in the actual receiver are omitted. In place for a remote control 116 shown in FIG. 3, it is also possible to utilized a pointing device such as a mouse.
There are shown a light emitting portion 301 for outputting an infrared signal to a light receiving portion 115, a power supply button 302 for turning on/off the power supply of the receiver 100, cursor keys 303 for vertically and horizontally moving a selection cursor, a decision button (enter button) 304 for instruction the selection of an area designated by the selection cursor, and a D button 307 for designating a display of a data broadcast image. Four buttons 306, called color keys, are constituted of “blue”, “red”, “green” and “yellow” buttons from left to right. Ten keys 305 are used for entering a channel number or a numeral. A P-button 308 will be explained later.
In the following, print contents data will be explained. For the transmission of the print contents data, there can be utilized, for example, a table, a descriptor, and parameters described in ISO/IEC 13818, PSI (program specific information) in ARIB technical data or DSM-CC. The print contents data may also be transmitted in another method.
The print contents data separated by the demultiplexer 103 are constituted of text information, script information and image information, and described in XML (extensible markup language) defined in W3C.
There will be given an explanation on the supplementary information on the print contents. FIG. 4 shows an example of the description of a table PIT (print information table) describing the supplementary information on the print contents. FIG. 4 shows a case wherein N print contents are present within a table.
A header information field 401 describes parameter information necessary for extracting the PIT in the demultiplexer 103, and principally includes Table_ID, Section_Number, and Service_ID, which have the same meanings as in the aforementioned EIT. The Table_ID and the Section_Number allow to identifying a time width in which the print contents are transmitted. The Service_ID allows identifying a table describing information of a channel for which print information is transmitted.
A parameter description field 402 of print contents 1 describes an ID value given to each print contents, a transmission start time of the print contents 1, a transmission continuation time of the print contents 1, and a flag indicating whether the print contents 1 are charged or not.
A parameter description field 403 of the print contents 1 describes information indicating an optimum sheet size (for example A3 or A4) for printing the print contents 1, information indicating information contained in the print contents 1 (for example, a photograph, a text and a pattern), a number of sheets in case of printing the print contents 1, a data capacity of the print contents 1, and a flag indicating whether or not the print contents 1 may be recorded in a recording medium in addition to a printing.
A parameter description field 404 of the print contents 1 describes a charge, in case the information in the field 403 indicates that the contents are charged.
A parameter description field 405 of the print contents 1 describes text information representing a title of the print contents 1.
A parameter description field 406 of the print contents 1 describes text information describing the content of the print contents 1.
A field 407 contains descriptions similar to those in the fields 402 to 406 on other print contents, in repetition by a number of such print contents. In case there are N print contents, the field 407 describes the information of (N-1) print contents.
The PIT shown in FIG. 4 is given a time zone in which the print contents are transmitted, a Table_ID, a Section_Number and a Service_ID corresponding to the channel and are multiplexed as plural table information with the TS data for transmission. The PIT is separated by the demultiplexer 103, decoded by the data stream process unit 106 and stored in the memory 107 through the bus 120.
In response to a predetermined instruction from the operation unit 114 or the remote control 116 through the light receiving portion 115, or in case the P-button 308 in FIG. 3 is depressed in the present embodiment, the CPU 118 reads the decoded PIT information from the memory 107 and outputs it to the image construction unit 108. The image construction unit 108 constructs a PCG (printable contents guide) image for a list display of transmission schedule of the print contents and supplementary information. Such PCG image is displayed by the display controller 109 and the image display-112. FIG. 5 shows an example of the PCG image.
Referring to FIG. 5, 501 indicates time information on a data transmission schedule. 502 indicates a data transmission channel number. 503 indicates a selection cursor, which can be moved by the cursor keys 303 of the remote control 116 shown in FIG. 3. 504 is an area for displaying supplementary information on the print contents in the area selected by the selection cursor 503. 505 indicates a title of the print contents in the area selected by the selection cursor 503, and corresponds to the text information described in the field 405 in FIG. 4. 506 shows the content of the print contents in the area selected by the selection cursor 503, and corresponds to the text information described in the field 406 in FIG. 4. 507 indicates a printable time of the print contents in the area selected by the selection cursor 503 and whether such printing is charged or not, and corresponds to the information described in the field 402 in FIG. 4.
508 indicates a charge in case of printing, and corresponds to the information described in the field 404 in FIG. 4. 509 indicates a print sheet size, a type of contents data, a print sheet number and whether the contents data can be recorded in a recording medium, and corresponds to the information described in the field 403 in FIG. 4. 510 is a mark for designating a user action in case of printing or reversing a printing for the print contents. Such user action will be explained later.
511 is an area for indicating status information relating to a connected printer (corresponding the printer 132 shown in FIG. 1). It is now displayed that the printer is in a printable state without an error, together with an estimated print completion time in the contents printing. In case that the power supply is not turned on or a trouble or an error such as a paper jamming or an ink exhaustion, a message of that effect is displayed in this area. The estimated print completion time is calculated and estimated by the CPU 118, based on the information described in the parameter description field 403 in FIG. 4 and performance information (print resolution information and print speed information) transmitted from the printer 132 connected to the receiver 100.
In the display shown in FIG. 5, the user can observe a schedule of the print contents (titles: print contents A, B, C to J, K, L) transmitted in channels 100 to 103 within a range of 19:00 to 23:00. FIG. 5 also indicates that the “print contents C” are selected by the selection cursor 503, and that the “print contents C” have a content “there are full of picture of sport players and idols” and the supplementary information of the print contents C indicates a printable time of 19:00 to 21:00, a print charge of 500 Yen, an A4 sheet size, a data type of photograph, a print sheet number of 15 sheets and a recording not permitted.
Now there will be explained a user action to the mark 510 shown in FIG. 5. In a position of the selection cursor shown in FIG. 5, the user can execute or reserve a printing of the print contents C by depressing the “red” button of the color keys 306 and the “1” key of the ten keys 305 in the remote control. For example, in case the current time is 19:30, the print contents C are transmitted in the channel 101, so that a printing is initiated. Also in case the current time is 18:30, the print contents C are still before the transmission start time, so that a printing is reserved. An example of a reserving image is shown in FIG. 6.
Referring to FIG. 6, 601 indicates an area for displaying the type of the printer 132 connected to the receiver 100 (printer “A” in FIG. 6). 602, 603, 604 and 605 are items for designating when and how the print contents are printed by the user. In case the user selects 602, “print at the transmission start time of print contents”, the printing of the print contents C is started at 19:00 which is the transmission start time thereof. In case the user selects 605, “start print at designated time”, the print start time is designated by entering a desired time in a time input area 606 with the ten keys 305 of the remote control. Thus a printing is reserved. In case a print reservation time is set and a printing is reserved, information of the printer connected at such time is stored in the memory 107 through the CPU 108 and the bus 120.
In case the user selects 603, “automatic preview display”, contents preview data transmitted together with the print contents are displayed on the image display 112 at 19:00 which is the transmission start time of the print contents C. An example of such image is shown in FIG. 7. In a preview image as shown in FIG. 7, a thumbnail image reduced with a lower resolution is displayed for each print contents.
In case the user selects 604, “automatic preview print”, contents preview data transmitted together with the print contents are printed, at 19:00 which is the transmission start time of the print contents C, by the printer 132.
In the image shown in FIG. 6, the print reservation is made assuming that the printer connected to the receiver 100 is the “printer A”, but, in case the connected printer is changed before the start of printing, a warning is displayed on the image display 112. An example is shown in FIG. 8.
Referring to FIG. 8, 801 indicates a TV image viewed by the user after the printing reservation is made. 802 indicates an OSD display of a warning displayed when the printer connection is changed after the printing reservation. The CPU 118, upon detecting a change in the type of the printer through the 1394 I/F 122 and the bus 120, causes the image display 112 to display a warning as shown in FIG. 8, through the bus 120, the image construction unit 108 and the display controller 109. An example of the display shown in FIG. 8 informs the user of a fact that the estimate time to the printing completion is changed from 20 minutes to 1 hour by the change of the printer. The estimated print completion time is recalculated by the CPU 118, based on the information in the parameter description area 403 in FIG. 4 and the performance information (print resolution information and print speed information) transmitted from the newly connected printer. Upon observing such display, the user can instruct a continuation of the printing reservation to the CPU 118 by the “blue” button of the color keys 306 of the remote control 116 and a cancellation of the printing reservation to the CPU 118 by the “red” button of the color keys 306 of the remote control 116.
FIG. 9 shows an example of the PCG image when print contents F are selected by the selection cursor 503. As in FIG. 6, the area 504 displays the supplementary information of the print contents F, which are recordable as indicated by 909.
As the print contents F are recordable as indicated by 909, the user can execute printing, recording, print reservation and/or recording reservation in the illustrated state of the selection cursor, by depressing the “green” button of the color keys 306 and the “2” key of the ten keys 305 of the remote control 116. The contents data are recorded in the accumulating unit 119.
For example, in case the current time is 20:10, the print contents F are already transmitted at the channel 102 and can be printed or recorded. An example of the image displayed in such case is shown in FIG. 10.
In case the user selects 1001, “immediately print print contents”, the printing of the print contents F is promptly started.
In case the user selects 1003, “preview display”, a preview image of the print contents F corresponding to FIG. 7 is displayed.
In case the user selects 1004, “print preview”, the preview image is printed.
In case the user selects 1006, “start print at designated time”, the printing can be reserved by setting the print time by entering a desired time in a time input area 1007. In case the user sets a time other than the printable time of the print contents F in the time input area 1007, the print contents are recorded after the time setting in the area 1007 and the printing is started at the time entered in the time input area 1007.
In case the current time is 19:10, the print contents F are not yet transmitted at the channel 102 so that the printing, recording and display are all reserved. An example of the image displayed in such case is shown in FIG. 11.
In case the user selects 1101, “print at the transmission start time of print contents”, the printing of the print contents F is started at 20:00 which is the transmission start time thereof.
In case the user selects 1102, “automatic preview display”, a preview image of the print contents F corresponding to FIG. 7 is displayed at 20:00 which is the transmission start time thereof.
