Title: Multimedia reproducing apparatus and reproducing method

Description:
TECHNICAL FIELD  
      This invention provides a multimedia reproducing apparatus and a multimedia reproducing method and, more particularly, to a multimedia reproducing apparatus and a multimedia reproducing method, providing a user interface for instructing multimedia reproduction.  
      This present invention contains subject matter related to Japanese Patent Application JP 2003-149924, filed in Japan on May 27, 2003, the entire contents of which are incorporated herein by reference.  
     BACKGROUND ART  
      Recently, the process of diversification of so-called digital home electrical appliances is proceeding. For example, in recording a television program, a hard disc recorder, a DVD (Digital Versatile Disc) recorder or a composite system thereof, is used. In music reproduction, variegated equipment are used for reproducing compressed data recorded in a large variety of memory cards or hard discs, in addition to apparatus for reproducing conventional CDs (Compact Discs).  
      Since the digital home electrical appliance, in particular the appliance configured for reproducing pictures or music, is anticipated to be used in common by plural viewers, it is installed in many cases in a common space in a home, such as a living space. Since an operating panel or a controller of a digital home electrical appliance has a smaller number of buttons and a narrow display space, the operating contents are sometimes displayed in a display area different from the main body unit of the appliance, for example, in an area of the television screen. The television screen is viewed from a certain distance, such that movement of a string of fine size letters or characters, or a small-sized pointer, such as is made on a PC viewing surface, is not suited to the display on a television screen. Hence, visual amenity and simple operations are required of the user interface of a digital home electrical appliance employing a television screen. In particular, for a user who is not accustomed to a PC, operating methods routinely used on a PC may not be optimum in handiness.  
     DISCLOSURE OF THE INVENTION  
      In view of the above depicted state of the art, it is an object of the present invention to enhance the convenience on the part of a user in multimedia reproduction.  
      A multimedia reproducing apparatus according to the present invention comprises an operating unit for acquiring a command concerning reproduction of contents through an operation from a user, a storage unit for holding data of a plurality of media icons indicating the types of media reproducible by the apparatus, contents to be reproduced by the apparatus and data of a plurality of contents icons indicating items of the contents, a display output unit for outputting picture data of a menu picture image, pertinent to reproduction of the contents, to a display device, and a display controller for generating picture data of the menu picture image in the form of a two-dimensional array of plural media icons and plural contents icons, based on a command from the user acquired by the operating unit. The display controller arrays the plural media icons in a first direction on a picture image, while arraying the plural contents icons in a second direction intersecting the first direction on the picture image, and generating picture data on the menu picture image, as the media icon and the contents icon, positioned in the vicinity of a point of intersection of an array in the first direction and an array in the second direction, are displayed highlighted for distinction in appearance from the remaining media icons and contents icons.  
      The ‘contents’ herein denotes information contents containing moving pictures, speech or the text, reproduced, displayed or executed through plural sorts of information transmitting means and, in particular, may contain the information for amusements. The ‘media’ herein may denote means mediating or transmitting the information, such as hard discs, optical discs, memory cards or broadcast networks, or may denote data types, such as data formats or compression formats.  
      In a multimedia reproducing apparatus, a user selects his/her favorite contents from a large number of contents over plural media types. If these contents are arrayed on the media basis, the result may presumably be a two-dimensional array in which the media and the contents associated with the media are arranged in a matrix configuration. If this large number of contents is displayed on the entire picture image, the two-dimensional array would be onerous to the user. Such is not the case with an embodiment of the present invention in which only one column or row of the media types and only one row or column of the items of the contents associated with a specified media are displayed. Moreover, this display would be suggestive of a two-dimensional expanse of the arrangements of the media types and the items of the contents. Consequently, the present invention provides to the user an intuitive interface in selecting the contents.  
      The operating unit may acquire a command for scrolling the array in the first direction or the array in the second direction, and a command for reproducing the contents. The display controller may generate picture data of the menu picture image, in keeping with the scroll command, so that, as the point of intersection of the array in the first direction and the array in the second direction is kept unchanged at a preset position, the plural media icons or the plural contents icons are displayed by scrolling. In case of issuance of a command for contents reproduction, the display controller may commence the reproduction of the contents specified by the contents icon positioned in the vicinity of the point of intersection. When the point of intersection of the array in the first direction and the array in the second direction is kept unchanged at a preset position, the contents of interest may be displayed at all times in the preset position, and hence the user may readily comprehend the contents, because he/she does not have to shift his/her viewpoint.  
      The display controller may generate the picture data of the menu picture image, as the media icon or the contents icon positioned in the vicinity of the point of intersection of the array in the first direction and the array in the second direction is positioned at substantially the center on the picture image. Since the icon of interest is displayed at substantially the center on the picture image, the user needs only to shift his/her viewpoint to the least extent, as when switching is to be made to the menu picture image during reproduction of the contents, and hence the user is able to comprehend the contents easily. In addition, the icon of interest is fixedly positioned at substantially the center on the picture image, so that a large number of the contents may be visually comprehended with the sense of wholeness.  
      The operating unit may acquire a command pertinent to a position at which the point of intersection of the array in the first direction and the array in the second direction is to be displayed on the picture image, through an operation from a user. The display controller may generate picture data on the menu picture image as the point of intersection is at the position on the picture image relating to the command. This allows the user to set the position of interest more flexibly.  
      The storage unit may hold data of a thumbnail contracted in size from a frame picture contained in the moving picture data or still picture data as the contents icon specifying the items of the contents. This allows the user to comprehend the contents at a glance. The attribute information, such as title, reproducing time or the data size, may be displayed together in the neighborhood of the thumbnail.  
      The operating unit may include buttons capable of indicating the up-direction, down-direction, left-direction and the right-direction. When two directions, namely one of the up-direction and the down-direction (first direction) and one of the left-direction and the right-direction (second direction), are indicated simultaneously, the display controller generates picture data of the menu picture image as it prioritizes the scroll display in the first direction or the scroll display in the second direction. This allows prevention of a mistaken operation of a user indicating an oblique direction against his/her intention in case the operating unit used is capable of indicating not only the four directions of the up-direction, down-direction, left-direction and the right-direction, but the oblique directions.  
      The display output unit-may output-the contents and picture data of the menu picture image to a television receiver connected outside as a display system. When the television screen is used as a picture image, the user ordinarily is at a certain distance from the screen, in a manner different from the case of a picture image of a PC. Hence, if an interface used for a PC is used as an interface for display on a television screen, it may be feared that hindrances may be produced not only from the visual sense but also from user friendliness. In the present embodiment, such an interface may be provided to the user which, when used for display on a television screen, may allow for facilitated visual recognition of the subject of operation for the user.  
      A multimedia reproducing method according to the present invention comprises the steps of acquiring a callout command for a menu picture image generated on two-dimensionally arraying a plurality of media icons specifying the types of media reproducible in connection with reproduction of contents and a plurality of contents icons specifying the items of reproducible contents, arraying, responsive to the callout command, the plural media icons and the plural contents icons in a first direction on the picture image and in a second direction intersecting the first direction on the menu picture image, and generating picture data on the menu picture image as the media icon and the contents icon positioned in the vicinity of a point of intersection of an array in the first direction and an array in the second direction are displayed in a highlighted fashion for distinction in appearance from the remaining media icons and contents icons, and outputting the picture data of the menu picture image to a display system.  
      In the multimedia reproducing method, according to the present invention, since the media types and the items of the contents related to the specified media are displayed each as one column or row, the display contents on the picture image are not onerous. Additionally, the display may be suggestive of a two-dimensional expanse of the arrangements of the media types and the items of the contents. Thus, the present invention provides an intuitive interface for the user in selecting the contents.  
      Other objects and more concrete advantages of the present invention will become more apparent from the following explanation of preferred embodiments which will be made with reference to the drawings.

     BEST MODE FOR CARRYING OUT THE INVENTION  
      In the following, a multimedia reproducing system, embodying the present invention, will be explained in detail with reference to the drawings.  
      A multimedia reproducing system according to the present invention is a composite system capable of reproducing or executing plural contents across plural media, such as still pictures, moving pictures, music, broadcast or games. For a picture image, a screen of a TV receiver is used and, as actuating means, display contents on the picture image and operating buttons of a controller are used. When reproducing plural contents across plural media on a PC, individual programs, such as dedicated viewers, are used for the respective contents. These individual programs are created by different vendors and usually do not own common interfaces. There is no sense of unity among the respective operating methods. If these are unified in a common interface, such as a so-called portal picture image, the result is mere ensemble. Moreover, since much time is taken to launch the respective programs, the user may not feel agreeable in carrying out the operation of program switching.  
      In the multimedia reproducing system of the present invention, contents reproduction of plural media is unified under a common interface, and common operability is afforded to the user. In addition, delay in the operations in switching between media is eliminated to assure prompt real time switching. An interface which realizes visual acuity and simplified operability to appeal to the user&#39;s intuition is provided to enhance the amenity on the part of the user.  
       FIG. 1  shows a basic configuration of a multimedia reproducing system  10 . The functions of the multimedia reproducing system  10  are centered about a multimedia reproducing apparatus  20 . To the multimedia reproducing apparatus  20  are connected a television receiver  30  and an operating unit  40 . The television receiver  30  has the function of displaying and outputting pictures or the speech, output from the multimedia reproducing apparatus  20 , and is externally connected to the multimedia reproducing apparatus  20 . The operating unit  40  is a device acted upon by the user to acquire various commands concerning contents reproduction, and operates as a part of the multimedia reproducing apparatus  20 . This operating unit  40  may be operated as part of the multimedia reproducing apparatus  20 , or may be implemented as a controller for games or as a remote controller used for controlling various functions provided to the multimedia reproducing apparatus  20 .  
      To the multimedia reproducing apparatus  20 , the information is supplied via various media. As broadcast contents, program data, such as pictures or speech, are entered over a television network  32  to the multimedia reproducing apparatus  20 . The broadcast contents may be recorded by the multimedia reproducing apparatus  20  or may be output to the television receiver  30  through the intermediary of decoding processing carried out by the multimedia reproducing apparatus  20 . As for web contents, data on the web are entered to the multimedia reproducing apparatus  20  over a network  34  of the Internet. The web contents may be saved in the multimedia reproducing apparatus  20  or utilized by a variety of functions provided to the multimedia reproducing apparatus  20 , such as game functions.  
      The multimedia reproducing apparatus  20  has a function of reading out data stored in an optical disc  36 , such as DVD or CD, and a function of reading out or writing data stored in a removable memory card. The multimedia reproducing apparatus  20  may read in data of a motion picture or a music album from the optical disc  36  or read in data such as images or pictures captured from a memory card  38 .  
       FIG. 2  depicts a functional block diagram showing the configuration of a multimedia reproducing apparatus. The multimedia reproducing apparatus  20  includes the operating unit  40 , a data input/output unit  44 , a display output unit  46 , a display controller  48 , a storage unit  80  and a game running unit  82 . The multimedia reproducing apparatus  20  may be implemented by hardware components, including the CPU, a hard disc, a memory or a rendition circuit of a computer, as long as the hardware structure is concerned, and by programs for realization of various functions, such as data inputting functions, data retention functions, picture image processing functions or rendition functions, as long as the software aspect is concerned.  FIG. 2  depicts, in a block diagram, the functions realized by the concerted actions of the components or programs. That is, the above functional blocks may be realized in a variety of ways by the combination of hardware and software phases.  
      The operating unit  40  includes a direction decision unit  92  for acquiring a command for any one of four directions of up, down, left and right, through the user&#39;s action, and a command decision unit  94  for acquiring the commands, such as reproduction of contents, stop of reproduction or call for a menu picture image, through user operations. The direction decision unit  92  and the command decision unit  94  are each made up by the combination of plural buttons, circuits for detecting button pressing and programs for recognizing the detection. The buttons provided as the direction decision unit  92  may be cross-keys or joysticks. The commands for oblique directions by the direction decision unit  92  may be of the digital system recognizing the command for the oblique direction by bi-level values, or of the analog system recognizing it with three or more plural values. No matter which of these systems is used, the operating unit  40  deems that, when a command for oblique directions has been acquired, such command is for an up-and-down direction or a left-and-right direction. In the present embodiment, the command for the up-and-down direction is prioritized, such that the command for the oblique direction is deemed to be that for the up-and-down direction.  
      Out of the buttons, provided as the command decision unit  94 , those buttons associated with the call command for a menu picture image are of the toggle system in which display of a menu picture image is switched to non-display of the menu picture image or vice versa each time the button in question is pressed. The information acquired in the respective parts of the operating unit  40  is sent to the display output unit  46 , display controller  48  and to the game running unit  82 .  
      The data input/output unit  44  includes a broadcast inputting unit  84 , for inputting broadcast contents over the television network  32 , a network communication unit  86  for inputting/outputting data, such as web contents, over the Internet network  34 , a disc readout unit  88  for inputting data stored in the optical disc  36 , and a memory card readout unit  90  for inputting/outputting data between it and a memory card  38 . The data entered via respective units making up the data input/output unit  44  are sent to the display output unit  46 , display controller  48 , storage unit  80  and to the game running unit  82 .  
      In the storage unit  80 , there are stored contents, such as broadcast contents, supplied over the television network  32 , web contents supplied over the Internet network  34 , contents, such as music or motion pictures, read in from the optical disc  36  or still pictures as well as moving pictures read in from the memory card readout unit  90 . In the storage unit  80 , there are further stored data of plural media icons, indicating the types of reproducible media, and data of plural contents icons, indicating the items of respective contents. These media icons and contents icons are used for item demonstration for a menu picture image.  
      The display output unit  46  includes a decoding processor  96  for decoding encoded data, an output buffer  100  for temporarily storing replay data, which are ready to be output to the television receiver  30 , before the replay data are output, an on-screen buffer  102  for temporarily storing picture data for on-screen display demonstration, which are ready to be output to the television receiver  30 , before the data are output, and a synthesizer  98  for synthesizing the replay data and the picture data. The decoding processor  96  operates, based on a user&#39;s command, acquired by the operating unit  40 , to decode the encoded replay data, such as broadcast contents, motion pictures or music, received from the data input/output unit  44  or from the storage unit  80 , and to store the decoded data in the output buffer  100 . In the on-screen buffer  102  are stored picture data of the menu picture image, generated e.g. by the display controller  48 , as picture data for on-screen display. The synthesizer  98  synthesizes the replay data stored in the output buffer  100  and the picture data of the menu picture image, stored in the on-screen buffer  102 , and converts the resulting data into analog signals, which are then output to the television receiver  30 .  
      The display controller  48  includes a menu management unit  104 , for supervising the media types and the functions provided from one media to another, as menu items, a contents controller  106  for controlling the reproduction or execution of respective contents, an effect processor  108  for processing the movements of icons on the menu picture image, and a picture image generator  110  for generating picture data on the menu picture image. The menu management unit  104  holds on memory the items of contents saved in the storage unit  80  and the items of contents entered via data input/output unit  44 , while also holding on memory the media and the contents as now selected. Based on the user&#39;s command, as acquired by the operating unit  40 , the contents controller  106  controls the reproduction of the media and the contents, data inputting by the data input/output unit  44 , data inputting by the storage unit  80  and the processing by the game running unit  82 .  
      The picture image generator  110  generates a menu picture image formed by a horizontal array of plural media icons and a vertical array of plural contents icons. These two arrays intersect each other at a mid part of the picture image and the media icon as well as the contents icon, demonstrated at the point of intersection and in its vicinity are displayed highlighted for distinction from the remaining icons. The effect processor  108  takes charge of scroll display of the media icon array and the contents icon array and highlighted demonstration of media and contents icons of interest. The highlighted demonstration of the icon is realized by the demonstration format different from that for other icons, such as by demonstration with colors different from those of the other icons, color changes, enlarged demonstration of the icons and movements of transition to the ultimate state of demonstration.  
      The game running unit  82  executes the game program read out from the optical disc  36  by the disc readout unit  88  or the game program read out from the storage unit  80 . The game running unit  82  processes the movements of the game program, based on the user&#39;s commands, as acquired by the operating unit  40 , while sending the pictures and the speech of the game to the display output unit  46 .  
       FIG. 3  shows the construction of a menu picture image generated by the multimedia reproducing apparatus. On a display picture image  50 , there is demonstrated a two-dimensional array comprised of a media icon array  70  made up by plural media icons in the horizontal direction and a contents icon array  72  made up by plural contents icons in the vertical direction and which is intersected by the media icon array. The media icon array  70  includes, as marks specifying the types of the media reproducible by the multimedia reproducing apparatus  20 , a photo icon  52 , a music icon  54 , a moving picture icon  56 , a broadcast icon  58 , a disc icon  60  and a game icon  62 . The contents icon array  72  includes icons, such as thumbnails, of plural contents stored in the storage unit  80 . The menu picture image, formed by the media icon array  70  and the contents icon array  72 , is an on-screen display, and is demonstrated in superposition on the foreground of the contents picture. When the contents picture, currently being reproduced, is demonstrated in a background area  74 , the effect processor  108  may color the entire area of the media icon array  70  and the contents icon array  72 , for distinction in appearance from the background area  74 , or may otherwise provide for such distinction in appearance, such as by adjusting the brightness of the contents picture.  
      The media icon, located at the intersection of the media icon array  70  and the contents icon array  72 , is displayed to an enlarged scale, in a color different from the color of the other media icons, for illustration as moving picture icon  56 . An area of intersection  76  is fixed, as it is kept at a mid portion of the display picture image  50 . The media icon array in its entirety is moved in the left-and-right direction, responsive to the user&#39;s command for movement in the left-and-right direction, mediated by the operating unit  40 , and the media icon, located in the area of intersection  76 , is changed in color and icon size. Consequently, the user has only to give direction commands for the left or right direction, while a decision command, such as mouse click on the PC, may be dispensed with.  
      The effect processor  108  realizes movements of the media icons in the left-and-right direction by scrolling the entire area of the media icon array  70  in the left-and-right direction. Since the media icons, included in the media icon array  70 , are carousel-displayed, the user has merely to continue to indicate either the left or the right direction to sequentially display any of the media icons at a mid position of the picture image  50 . As long as the media icons is performing leftward or rightward movement, the effect processor  108  displays them with the same color and to the same size and, when the leftward or rightward movement has ceased, such that one of the media icons is ultimately set in position at the area of intersection  76 , the effect processor causes the media icon to be changed in color and size. The effect processor  108  may cause the attributes of the colors of the media icons, such brightness, saturation and color hues, or cause the colors to be changed by flickering. By demonstrating the media icon, located at the area of intersection  76  by the display mode different from that for the other media icons, the user may readily select the media.  
      If the media icons are being moved in the left or right direction such that none of the media icons is located at the area of intersection  76 , the effect processor  108  does not display the contents icon array  72 . When the media icon of interest is ultimately located in the area of intersection  76 , the effect processor displays the contents icon array  72  as it is paid out vertically in an extending fashion beginning from the area of intersection  76 . The user has only to scroll the media icons in the left-and-right direction, with the area of intersection  76  as the target point, to permit the user to recognize the contents belonging to the media. In addition, the user may recognize the media from the contents displayed in an extending fashion. If conversely a command for left-and-right operation is issued as the contents icon array  72  is displayed, the effect processor  108  displays the contents icon array  72  so that it is housed from its extended position towards the area of intersection  76 .  
      An area of interest  75 , located at a mid portion of the picture image  50 , is an area where the icon of the contents, as a target acted upon by the user, remains fixed at the mid portion of the picture image  50 . The picture image generator  110  displays the media icon array  70  so that the area of intersection  76  is located in the neighborhood of, more specifically, directly above, the area of interest  75 . This area of interest  75  forms a part of the contents icon array  72 , and the effect processor  108  displays the contents icon, located in this area of interest  75 , to an enlarged scale, as a thumbnail of interest  64 . As other contents icons, picture image thumbnails  66  are displayed to a size smaller than the size of the thumbnail of interest  64 . In the vicinity of, specifically to the right of, the thumbnail of interest  64 , there are displayed a title and the date of recording, as attributes of the picture image of the thumbnail of interest  64 .  
      During the time the operating unit  40  acquires the user&#39;s command for the up-and-down direction, the contents icons are moved in the up-and-down direction, responsive to the command. The effect processor  108  realizes the movement in the up-and-down direction of the contents icons by scrolling the area of the contents icon array  72  in its entirety in the up-and-down direction. Since the contents icons, contained in the contents icon array  72 , are also carousel-displayed, the user has only to continue to indicated the up-direction or the down-direction to sequentially display the totality of the contents icons on the picture image  50 . When the user has commanded an oblique direction to the operating unit  40 , the operating unit deems the command to be that for the up-and-down direction, and hence the scroll display of the contents icon array  72  is prioritized, thus prohibiting a mistaken operation that the media is inadvertently changed by scrolling in the left-and-right direction of the media icon array  70  during the time the user is scrolling plural contents.  
      During the time the contents icons are moved quickly in the up-and-down direction, the effect processor  108  displays these contents icons to the same size. When the movement in the up-and-down has ceased such that the contents icon of interest has ultimately been located in the area of interest  75 , the effect processor enlarges the size of the thumbnail of interest  64  which is the contents icon. The effect processor  108  may further change the attributes of the colors, namely the brightness, saturation and color hues, of the thumbnail of interest  64 , or display it with flickering. When the operating unit  40  has received a reproduction decision command of the contents, indicated as the thumbnail of interest  64 , from the user in this state, the picture image generator  110  halts displaying the picture data of the menu picture image and the contents controller  106  begins to reproduce the so selected contents. If, during contents reproduction, the user has commanded to call the menu picture image, through the operating unit  40 , the menu picture image is displayed in superposition on a live picture image of the contents being reproduced. The state under which the decision for reproducing the contents was given is now reproduced on the menu picture image demonstrated at this time.  
      The picture image generator  110  demonstrates the media icon array  70  in an area slightly above a mid portion along the vertical direction of the picture image  50 , while demonstrating the contents icon array  72  in an area slightly shifted towards left from the center along the horizontal direction of the picture image  50 . This enables the thumbnail of interest  64  and its attributes to be displayed at a mid portion of the picture image  50 . The user is able to see the thumbnail of interest  64  and its attributes at a mid portion of the picture image  50  to comprehend the contents thereof easily.  
      The photo icon  52  is an icon to be selected when reproducing the picture image stored in the storage unit  80 . The picture to be reproduced is mainly a still picture and a moving picture as captured by a digital camera and read in from, for example, a memory card  38 . The contents icons, displayed in an extending fashion when the photo icon  52  is located in the area of intersection  76 , are thumbnails of still or moving pictures. As attributes, the capturing information, such as date of photographing or the file size, is displayed.  
      The music icon  54  is an icon to be selected in reproducing music data stored in the storage unit  80 . The music data to be reproduced is data read in from e.g. the optical disc  36  and encoded in a specified compression format. The contents icons, displayed in an extended fashion when the music icon  54  is positioned in the area of intersection  76 , may be displayed on the musical number basis or on the album basis. As the attributes, the information such as title of the musical number or the album, or the reproducing time, is displayed. The music data may contain moving picture data, such as promotion video of the music number. In this case, the thumbnail of the moving picture may be used as a contents icon.  
      The moving picture icon  56  is such an icon to be selected in reproducing a recorded picture image stored in the storage unit  80 . The picture to be reproduced is a moving picture which has recorded a television program output from the television network  32 , or a moving picture captured by a digital video camera, and is encoded in a predetermined compression format. In this case, a thumbnail reduced in size from a frame contained in the moving picture is formed into a contents icon. As attributes, the information such as data of recording or the reproducing time is displayed.  
      The broadcast icon  58  is an icon to be selected in case of viewing a television program output from the television network  32 . The contents icon to be extended as a subject for viewing may be program-based, broadcasting-station-based or broadcasting-channel-based. As the attributes, the information such as name of a broadcasting station, name of a broadcasting channel, program title or the broadcast time, is displayed.  
      The disc icon  60  is such an icon which should be selected for viewing a picture image or the music stored in the optical disc  36 . If a DVD has been recognized as the optical disc  36 , the letters ‘DVD’ are displayed below the media icon and, when a CD has been recognized, the letters ‘CD’ are displayed below the media icon. If a moving picture is contained in the DVD or in the CD, the thumbnail of such moving picture is formed into a contents icon. If music is stored in the DVD or CD, a mark indicating music or a mark indicating a music number or or the genre of the music number is formed into a contents icon. As attributes, the information such as title of a picture or music or the reproducing time is displayed.  
      The game icon  62  is such an icon which should be selected for running a game program. The game program stored in the storage unit  80  or the game program read in from the optical disc  36  is executed. If a game icon is contained as data in the game program, such icon is displayed as a contents icon. As attributes, the information such as title of the game program is displayed.  
      As described above, the multimedia reproducing apparatus  20  displays a menu picture image, composed of an array of media and an array of contents, on the display picture image  50 . Although only one row or one column of the media icon array  70  and the contents icon array  72  is actually displayed, the icons of different contents of different media are sequentially displayed by scrolling in the up-and-down direction and in the left-and-right direction. Hence, such a feeling as if many contents are arrayed in a matrix configuration on the entire picture image may be entertained by the user. The user may select contents with such a feeling as if as he/she is moving a matrix comprised of many contents to focuses on a desired one of these contents. However, since the number of icons actually displayed on the picture image is small, no irksome feeling is imparted to the user. The user is able to select the contents one after another simply by instructing one of the upward, downward, left and right directions, and hence is able to perform the so-called zapping operation by a simple and comfortable operation. Since the position of the thumbnail of interest  64  is at approximately the center position of the display picture image  50 , at all times, the user is able to select the contents with a feeling as if he/she is peeping into desired contents from a window provided centrally of the display picture image  50 . In addition, even in case the user performs operations from a position away from the display picture image  50 , he/she is able to comprehend the position of the thumbnail of interest  64  at a glance. Consequently, the user does not have to take the pains of locating the position of the thumbnail of interest  64  in the display picture image  50 , such that an environment in which the user may operate with relaxed feeling may be imparted to the user.  
       FIG. 4  shows a typical picture image in which the functions provided by the multimedia reproducing apparatus are displayed by icons. When the operating unit  40  has acquired a command for calling out the menu of functions that may be executed by the user, in connection with the contents specified by the thumbnail of interest  64 , the picture generator  110  demonstrates an array of functional icons  78 . The array of functional icons  78  is displayed on the same row as the thumbnail of interest  64 , as the array is extended on its left and right sides. This array of functional icons  78  includes, for example, an icon indicating the option setting function, an icon indicating the contents inputting function, an icon indicating the contents re-arraying function, an icon indicating the contents editing function and an icon indicating the contents erasing function.  
       FIG. 5  depicts a flowchart showing the operational process for the multimedia reproducing apparatus. When the user has turned on the power supply of the multimedia reproducing apparatus  20 , the picture image generator  110  acquires an item, such as media icon or contents icon, to generate a menu picture image, which then is demonstrated by the display output unit  46  on the television receiver  30  (S 10 ). When the operating unit  40  has acquired a direction command towards left or right (S 12 Y), the effect processor  108  is responsive to the command to cause movement of the media icons towards left or right (S 14 ). The effect processor also highlights the display of the media icon ultimately positioned in the area of intersection  76  (S 16 ) and acquires the contents icons corresponding to the media from the storage unit  80  to display them as they are extended in the up-and-down direction (S 18 ). As long as there is no command for the leftward or rightward movement by the user, the steps S 14  to S 18  are skipped (S 12 N).  
      When the operating unit  40  has acquired a direction command above or towards below (S 20 Y), the effect processor  108  is responsive to the command to cause movement of the contents icons towards above or below (S 22 ). The effect processor also highlights the display of the media icon ultimately positioned in the position directly below the area of intersection  76  (S 24 ) and displays the attributes of the contents on the right side (S 26 ). As long as there is no command for the upward or downward movement by the user, the steps S 22  to S 26  are skipped (S 20 N).  
      The processing of the steps S 12  to S 26  is repeated until the operating unit  40  acquires the contents reproduction decision command (S 28 N). When the operating unit  40  has acquired the contents reproduction decision command (S 28 Y), the contents controller  106  commences the reproduction of the contents displayed highlighted directly below the area of intersection  76  (S 30 ). When the operating unit  40  has acquired a command for calling out a menu picture image from the user during contents reproduction (S 32 Y), the contents controller jumps to S 10  to execute the processing of S 10  to S 28  again. Lacking the command for calling out the menu picture image by the user, the contents reproduction is continued (S 32 N). If the operating unit  40  has acquired the command for stopping the contents reproduction from the user during contents reproduction, the contents controller  106  stops the contents reproduction (S 34 Y).  
      In the foregoing description, a preferred embodiment of the present invention, shown in the drawings, has been explained. However, as may be surmised by those skilled in the art, a large variety of modifications of the constituent elements or process steps may be encompassed in the scope of the invention. Certain ones of these modifications will now be explained.  
      In the above embodiment, the menu picture image is constructed so that the area of intersection  76  is located directly above the area of interest  75 . In a first modification, the menu picture image may be constructed so that the area of intersection  76  is located directly below or in the vicinity of the area of interest  75 , provided that position relationships are such that, as the user is gazing at the thumbnail of interest  64 , he/she may readily recognize the media icon. Also, in the present embodiment, the media icon array  70  and the contents icon array  72  are displayed in the horizontal and vertical directions on the display picture image  50 , respectively. As a further modification, the media icon array  70  and the contents icon array  72  may be demonstrated for extending in respective oblique directions.  
      In the above explanation, the media icon and the contents icon, located in the area of intersection  76  and in the area of interest  75  in the display picture image  50 , respectively, are displayed highlighted. In a further modification, the colors of the icons other than the media icon and the contents icon displayed in the area of intersection  76  and in the area of interest  75  may be changed stepwise from this mid area towards the terminal areas of the display picture image  50  to display the icons at the mid portions of the display picture image  50  in a relatively highlighted fashion. Such stepwise change in the color may be such a change of lowering the brightness or saturation towards the terminal area, or such a change of lowering the α-value at an area of merging to a contents picture being reproduced in the background area  74 .  
      In the above embodiment, the multimedia reproducing apparatus  20  is constructed and arranged so that the area of intersection  76  and the area of interest  75  are positioned at a mid area in the display picture image  50 . As a further modification of the present invention, the display positions for the area of intersection  76  and the area of interest  75  may be freely set by the user. That is, although the display positions of the area of intersection  76  and the area of interest  75  are desirably the mid portion of the display picture image  50 , such position may be set according to the liking of the user for more flexibly meeting the user&#39;s needs.  
      Several other modifications of the present invention will now be explained. In the above explanation of the present invention, the media icons are selected by scroll command in the up-and-down direction. However, the media icon may ultimately be selected by a definite decision command from the user. Similarly, in the foregoing explanation of the present invention, the contents icons are selected by scroll command in the left-and-right direction. Alternatively, the contents icon may ultimately be selected by a definite decision command from the user.  
      Likewise, in the foregoing explanation of the present invention, the menu picture image is configured to display the media icon array  70  at all times. Alternatively, the contents icon array  72  may be demonstrated at all times on the menu picture image without demonstrating the media icon array  70 , or neither the media icon array  70  nor the contents icon array  72  may be displayed. In these cases, the user may often comprehend which of the media is being displayed if only the thumbnail of interest  64  is displayed at all times. Hence, the configuration of the menu picture image may be flexibly set in keeping with the user&#39;s liking.  
      In the foregoing explanation of the present invention, only the contents of the same row or column as that of the media icon located in the area of intersection  76  are displayed as the contents icon array  72 . Alternatively, many contents icons may be arranged in a matrix pattern on the entire display picture image  50  by demonstrating the contents associated with other media, such as all media, on the menu picture image. The contents icons other than those of the contents icon array  72  may be demonstrated in a mode different from the display mode for the contents icon array  72 , such as by lowering the brightness or saturation.  
      The present invention is not limited to the above embodiments explained with reference to the drawings and various changes, substitutions or equivalents may be attempted by those skilled in the art with out departing from the scope of the invention as defined in the claims.
