  The program guide generation unit 21 generates a program guide for recorded programs based on information held in the database 12. The program guide generator 21 generates a playback list of recorded programs based on information held in the database 12 and user settings. The viewing / playback unit 22 acquires the program content from the recording unit 16 and plays it in response to a user operation on the program table generated by the program table generation unit 21 and displayed by the output unit 24. The input unit 22 receives a user operation. The output unit 23 displays a program guide generated by the program guide generator 21 and other setting screens. Further, the output unit 23 displays the video of the program content reproduced by the viewing / reproducing unit 21 and outputs sound.

  Note that the recording control unit 11 to the viewing / playback unit 22 are housed in a single casing.

  Next, the program information table 13 held in the database 12 will be described. As shown in FIG. 2, a plurality of program information 31 is registered in the program information table 13. Each program information 31 is based on the program information input from the program information acquisition unit 15 to the recording control unit 11 and is a television program to be broadcast in the future, or broadcasted (in other words, recorded). This is information corresponding to a television program whose program content has not been erased.

  FIG. 3 shows a configuration example of the program information 31. The program information 31 includes a program ID that is information for uniquely identifying the corresponding television program, a title (program name) of the corresponding television program, a broadcast station, a broadcast start date and time, and a broadcast end date and time. The Further, the program information 31 includes a storage location of program content corresponding to the television program (a detailed recording directory in any of the recording units 16-1 to 16-n), and an image quality of the program content corresponding to the television program ( Encoding method and bit rate information may be used), television program details (subtitles, performers, audience rating (added after broadcast), etc.), television program categories (drama, sports, quiz, variety, etc.) And information indicating the status of television programs (information indicating the distinction between unreserved, reserved, recorded, viewed, etc.). Of the information constituting the program information 31 described above, the storage location is written after the recording is completed, and the status is updated as appropriate.

  Next, the recording information table 14 held in the database 12 will be described. As shown in FIG. 4, a plurality of recording unit information 41 (the same number as the number n of the recording units 16) is registered in the recording information table 14. Each recording unit information 41 corresponds to a different recording unit 16, and includes information related to the corresponding recording unit 16. FIG. 5 shows a configuration example of the recording information 41. The recording unit information 41 includes a recording unit ID, which is information for uniquely specifying the corresponding recording unit 16 (any one of the recording units 16-1 to 16-n), in order to access the recording unit 16. URI (Uniform Resource Indicator) indicating the location of the required recording unit 16, broadcast station name that can be recorded (may be plural), broadcast station name that can be recorded (receivable broadcast station name), maximum recordable capacity (recording unit) 16) and a URI used for distributing the recorded program content (a URI when the viewing / reproducing unit 22 accesses). Of the information constituting the recording unit information 41 described above, information other than the maximum recordable capacity is preset information, and the maximum recordable capacity corresponds to the free capacity of the storage unit 19 constituting the recording unit 16. Will be updated accordingly.

  Next, the control information 51 held in the recording control unit 11 will be described with reference to FIG. The control information 51 includes a start time (for example, 4 am every day) of a recording control process (to be described later) executed every day, and a recorded program erasure condition (which is a criterion for automatically erasing recorded program content). For example, the recording after 1 week after recording is deleted), individual recording reservation information intentionally set by the user, deletion exclusion information indicating program content excluded from the deletion target by the user, and intentional by the user Are composed of recording exclusion information indicating television programs excluded from the target of recording reservation. Note that initial values are set for the recording control processing start time and the recorded program erasure condition, but the user can also change them.

  Next, recording control processing by the recording apparatus 1 will be described with reference to the flowchart of FIG. This recording control process is started when the recording apparatus 1 is activated.

  In step S <b> 1, the recording control unit 11 stands by until the current time reaches the recording control processing start time of the control information 51. If the current time reaches the recording control process start time, the process proceeds to step S2. In step S2, the recording control unit 11 deletes the program content that matches the recorded program deletion condition of the control information 51, and changes the free capacity of the storage unit 19 that configures the recording unit 16 that changes accordingly. The program content deletion process to be reflected in is performed. Details of the program content erasure process will be described later with reference to FIG.

  In step S3, the program information acquisition unit 15 is connected to the program information supply server 3 via the Internet 2 according to the control from the recording control unit 11, and among the program information respectively corresponding to all receivable television programs. Unacquired ones are acquired and supplied to the recording control unit 11. In step S <b> 4, the recording control unit 11 updates the program information table 13 by additionally registering the program information supplied from the program information acquisition unit 15. In step S <b> 5, the recording control unit 11 extracts the program information 31 registered in the program information table 13 that has an unreserved status, and commands recording reservation for the program corresponding to the extracted program information 31. A recording command (including at least a broadcast station, a broadcast start date and time, and a broadcast end date and time or broadcast time) is generated. Furthermore, the recording control unit 11 refers to the recording station name and the maximum recordable capacity of the recording unit information 41 registered in the recording unit information table 14 and sends the created recording command to the recording unit 16-1. To 16-n. Then, a list (hereinafter referred to as a recording command list) in which the recording unit 16 corresponding to the recording command is described is generated.

  In step S6, the recording control unit 11 determines whether or not all the recording commands included in the recording command list have been selected. In this case, since one recording command has not yet been selected, the process proceeds to step S7. In step S7, the recording control unit 11 selects one unselected recording command from the recording command list. In step S8, the recording control unit 11 notifies the selected recording command to the corresponding recording unit 16. In response to this recording command, the recording unit 16 executes reserved recording and accumulates program content and recording result information obtained as a result.

  In step S9, the recording control unit 11 updates the status of the program information 31 registered in the program information table 13 corresponding to the selected recording command to reserved. Thereafter, the process returns to step S6, and the subsequent processes are repeated. If it is determined in step S6 that all the recording commands included in the recording command list have been selected, the recording control processing for one day has been completed, so the processing returns to step S1 and the recording control processing for the next day. It will wait until the start time. This is the end of the description of the recording control process.

  Next, details of the above-described program content erasing process in step S2 will be described with reference to the flowchart of FIG. In step S21, the recording control unit 11 acquires recording result information (information specifying the recorded program, information indicating the storage location of the program content, etc.) accumulated in the storage unit 19 of each recording control unit 16. Based on the acquired recorded information, the information is added to the storage location item of the program information 31 registered in the program information table 13 of the database 12 and the status item is updated to recorded.

  In step S22, the recording control unit 11 extracts the program information 31 registered in the program information table 13 that matches the recorded program erasure condition of the control information 51, and the list (hereinafter, erased program). A list).

  In step S23, the recording control unit 11 determines whether all program information included in the erased program list has been selected. In this case, since no program information has been selected yet, the process proceeds to step S24. In step S24, the recording control unit 11 selects one piece of unselected program information from the erased program list. In step S <b> 25, the recording control unit 11 deletes the program content corresponding to the selected program information from the storage unit 19 of the corresponding recording unit 16. The recording unit 16 notifies the recording control unit 11 of the maximum recordable capacity of the storage unit 19 that is changed by deleting the program content. In step S <b> 26, the recording control unit 11 updates the maximum recordable capacity of the corresponding recording unit information 41 in the recording unit information table 14 based on the maximum recordable capacity of the storage unit 19 notified from the recording unit 16.

  Thereafter, the process returns to step S23, and the subsequent processes are repeated. If it is determined in step S23 that all program information included in the erased program list has been selected, the program content erasure process is terminated, and the process returns to step S3 in FIG. This is the end of the description of the program content erasure process.

  Next, viewing processing when a user views a recorded program will be described with reference to the flowchart of FIG. This viewing process is started in response to a predetermined user operation input from the input unit 23.

  In step S31, the program guide generation unit 21 presents the program contents held in the recording units 16-1 to 16-n to the user based on the program information table 13 of the database 12 according to the control from the viewing / playback unit 22. A program guide (for example, a program guide 81 as shown in FIG. 13) is generated. The creation of the program guide by the program guide generator 21 will be described later.

  In step S <b> 32, the output unit 24 presents the generated program guide to the user according to control from the viewing / playback unit 22 and prompts the user to select program content to be played back. In step S33, the viewing / playback unit 22 monitors the input from the input unit 23, and waits until the user performs a selection operation and a playback instruction operation for program content to be played back. When the selection operation and the reproduction instruction are performed, the process proceeds to step S34.

  In step S34, the viewing / playback unit 22 reads the program information 31 corresponding to the program selected by the user from the program information table 13, and holds the corresponding program content based on the storage location information described therein. The recording unit 16 being identified is specified. Further, the recording unit information 41 corresponding to the specified recording unit 16 is read out from the recording unit information table 14, and the URI is accessed based on the URI used for distribution described therein to correspond to the user's selection. Acquire and play program content. The reproduced video and audio are displayed or output by the output unit 24. This is the end of the description of the viewing process.

  By the way, in order for the user to view the recorded program, a plurality of programs are registered in addition to the method of reproducing the program selected one by one from the program table as in the viewing process described above. It is also possible to generate a reproduction list and perform reproduction based on the generated reproduction list. The process (hereinafter referred to as a reproduction process based on a reproduction list) will be described with reference to the flowchart of FIG.

  In step S41, the output unit 24 displays a search condition input screen necessary for generating the program guide and the reproduction list in accordance with the control from the program guide generating unit 21 corresponding to a predetermined operation from the user. , Prompt the user for input. FIG. 11 shows an example of a search condition input screen.

  The input screen 61 includes a URI input field 62, a category priority setting field 63, a performer / title setting field 64, a time length / newness setting field 65, a vertical / horizontal axis setting field 66, and a “search” button 67. , A “reset” button 68 and a “play by automatic list generation” button 69 are provided.

  In the URI input field 62, the URI input when accessing the input screen 61 is displayed. In the category priority setting column 63, a priority (for example, high or low) can be set for each category (drama, sports, quiz, etc.) of the program. There may be a category for which priority is not set. In the performer / title setting field 64, a performer name of a program and a word included in the title can be designated as a search condition. In the time length / newness setting column 65, the time length of the program and the newness of the program (elapsed time since recording) can be specified as search conditions. In the vertical axis / horizontal axis setting column 66, conditions (category, performers, time length, popularity (viewing rate), or newness) set on the vertical axis and the horizontal axis of the program guide can be respectively designated.

  The “Search” button 67 is pressed when creating a program guide according to the conditions set for the category priority setting field 63 to the vertical / horizontal axis setting field 66. The “reset” button 68 is pressed to reset the conditions set for the category priority setting field 63 to the vertical / horizontal axis setting field 66. A “play by automatic list generation” button 69 plays program content according to a first play list (described later) generated according to the conditions set for the category priority setting field 63 to the vertical / horizontal axis setting field 66. Pressed when

  The description will be continued assuming that the “Search” button 67 or the “Play by automatic list generation” button 69 is pressed. Returning to FIG. 10, in step S42, the program guide generation unit 21 refers to the program information table 13, and for each recorded program, each condition (category priority, performer, title, program time length, popularity, and new The degree of matching is calculated for each, and a predetermined number (for example, 20 programs) is extracted in descending order of the value. In step S43, the program guide generating unit 21 adds a degree of conformance to each condition to each recorded program (120 programs in this case) extracted for each condition, and gives a total score. . The total score is higher for a recorded program that is redundantly adapted to a plurality of conditions.

  In step S44, the program guide generation unit 21 determines whether or not the “play by automatic list generation” button 69 is pressed in the process of step S41. If it is determined that the “play by automatic list generation” button 69 has been pressed, the process proceeds to step S45.

  In step S45, the program guide generation unit 21 generates a first reproduction list with a predetermined number (for example, 10 programs) of recorded programs as elements in order from the highest total score assigned. Thereafter, the process proceeds to step S48. In step S48, the viewing / playback unit 22 sequentially plays back the programs registered in the generated play list (in this case, the first play list). The details are the same as the processing in step S34 of the viewing process described above, and will be omitted.

  If it is determined in step S44 that the “play by automatic list generation” button 69 has not been pressed, the “search” button 67 has been pressed, and the process proceeds to step S46. In step S46, the program guide generator 21 records only the number of frames of the program guide to be generated (in the example shown in FIG. 12, 49 (= 7 × 7)) in descending order of the total score given in step S43. The extracted program is extracted, and for each extracted recorded program, the conditions set on the vertical and horizontal axes of the program table in the vertical / horizontal axis setting column 66 (for example, the vertical axis is new and the horizontal axis The degree of conformance to the category is calculated by scoring. Instead of calculating here, the degree of adaptation calculated in the process of step S42 may be used.

  Then, the program guide generation unit 21 matches the condition (newness in this case) set to the vertical axis in the upper left frame of the program guide as the total score is higher among the 49 recorded programs extracted. The higher the degree is, the frame is assigned to the upper side of the program table, and the higher the degree of conformity to the condition (in this case, the category) set on the horizontal axis is, the higher the degree is, assigned to the left frame of the program.

  For example, as shown in FIG. 12, information relating to a recorded program having the highest overall score is arranged in the first frame of the program table to be generated. In the second frame, information having a higher degree of conformity to the conditions set on the vertical axis is placed among the recorded program information having the second and third total points. In the third frame, among the recorded program information having the second and third comprehensive points, the one having a higher degree of conformity to the condition set on the horizontal axis is arranged. Similarly, in the 4th to 6th frames, information of recorded programs with the 4th to 6th total points is arranged. At this time, refer to the one with higher consideration for the condition set on the axis. Is done. In the 49th frame, a recorded program having the 49th overall score is arranged.

  FIG. 13 shows a display example of the program table generated in this way. The program guide 81 is composed of 7 × 7 frames. In the program table 81, the vertical axis indicates the newness of the recorded program, and the horizontal axis indicates the category of the recorded program. The overall score is higher, the degree that matches the conditions set on the vertical axis is higher, the degree that matches the conditions set on the horizontal axis is higher, and the others are backgrounds. They are color-coded. However, in the drawings, the color coding is expressed by distinguishing the background pattern for the purpose of illustration.

  FIG. 14 shows a display example of frames constituting the program guide 81. In this frame 82, the title 91 of the recorded program, information (in this case, broadcast date) 92 corresponding to the condition (newness) set on the vertical axis, and the condition (category) set on the horizontal axis are displayed. Corresponding information 93 is displayed. The frame 82 also includes a check box 94 that is marked when the recorded program is displayed in the second list (described later), a “view” button 95 that is pressed when the recorded program is immediately played back, and the recorded program.
