It may be downloaded from a predetermined server or the like via a network and stored in the RAM 15. Further, the process in which the CPU 10 reads the program may be realized by hardware.

  Hereinafter, processing by the CPU 10 will be described. In the processing process performed by the CPU 10, information relating to a continuous program is used. A continuous program is a program that is scheduled to be broadcast more than once at intervals. First, the information regarding a continuous program is demonstrated.

  Television broadcasts received by the recording / reproducing apparatus 1 include terrestrial analog broadcasts, satellite digital broadcasts, and terrestrial digital broadcasts. Each of these television broadcasts is multiplexed with information relating to programs such as an electronic program guide.

  In terrestrial analog broadcasting, information related to a program is transmitted using a vertical synchronization section called VBI. In satellite digital broadcasting and terrestrial digital broadcasting, information relating to programs is transmitted using program arrangement information (SI: Service Information).

  FIG. 2 shows an example of the data structure of an electronic program guide transmitted using the VBI section of terrestrial analog broadcasting. The data structure of the electronic program guide uses a standard defined for text multiplex broadcasting. 2A shows a physical layer (first layer), FIG. 2B shows a link layer (second layer), and FIG. 2C shows a network layer (third layer).

  As shown in FIG. 2A, 296-bit data lines are used for each scanning line for data transmission using the VBI interval. Note that the tenth to thirteenth lines and the 273rd to 276th lines of the horizontal scanning line numbers are used for VBI data transmission.

  As shown in FIG. 2B, 24 bits from the top of the 296 bits of the data line are used as synchronization bits, and the remaining 272 bits are used as data packets. The first 16 bits of the synchronization bits are used as a clock line (CR) bit synchronization code, and the remaining 8 bits are used as a framing code (FC) byte synchronization code. The data packet is a shortened difference set cyclic code (272, 190), and is composed of a 190-bit data block and an 82-bit check code (for error correction).

  As shown in FIG. 2C, the 14 bits from the head of the data block are used as a packet prefix (PF) composed of LCI2, SCC, CI, and DTC, and the remaining 176 bits (22 bytes) are the data block. LCI2 is a code for logical channel identification 2, SCC is a code for scramble control, CI is a code for continuity index, and DTC is a code for data group control (TDF head flag and EDF end flag). ). 176 bits (22 bytes) of the data block shown in FIG. 2C can be used for data transmission such as electronic program guide data.

  FIG. 3 shows an example of a table configuration of electronic program guide data that can be used in an embodiment. The table shown in FIG. 3 includes items of “broadcast time”, “program ID”, “category”, “title”, “broadcast pattern”, and “number of stories”. Note that items describing information related to a continuous program such as “broadcast pattern” and “number of stories” are items not defined in the current electronic program guide, and are defined using an undefined area.

  The item “broadcast time” is data relating to the program broadcast time such as the start time and duration of the program, the item “program ID” is data for uniquely identifying the program, and the item “title” is the program The item “category” is data relating to the category of a program such as a news program or a sports program.

  The item “broadcast pattern” is data indicating a broadcast pattern of a program, such as whether the program is a single program or a non-single continuous program (hereinafter referred to as a continuous program). The item “number of stories” is data relating to the number of stories of the program, such as how many times the program is a continuous program and how many times it is finished.

  By acquiring the data of the electronic program guide by the analog video decoder 3 and reading information on such a continuous program, the broadcast pattern and the number of programs can be acquired in advance. In the example shown in FIG. 3, the analog video decoder 3 obtains the electronic program guide data and reads the data of the item “broadcast pattern” to determine whether the corresponding program is a continuous program. By reading the data of the item “number of stories”, it is possible to determine how many episodes the corresponding program is in.

  In satellite digital broadcasting, terrestrial digital broadcasting, and the like, an event information table (EIT: Event Information Table) representing program information is defined in program arrangement information (ARIB (Association of Radio Industries and Businesses) standard STD- (See B10).

  FIG. 4 shows an EIT structure defined in the ARIB standard STD-B10. In the EIT, a descriptor that describes detailed information about the program is defined. In FIG. 4, a series descriptor is inserted into descriptor () shown in [A]. The series descriptor is a descriptor that describes detailed information about a program such as a series drama or a series of program series.

  FIG. 5 shows the structure of the series descriptor (Series Descriptor). In “program_pattern” shown in [B], broadcast organization pattern information is described. For example, when 0 × 2 is written in “program_pattern”, it means weekly broadcast. In “episode_number” shown in [C], information on the number of programs indicating the number of programs is described. Information on the final number of programs is described in “last_episode_number” shown in [D].

  When the CPU 10 acquires the data of the electronic program guide from the stream passing through the internal bus 6 and reads such information related to the continuous program, the broadcast pattern and the number of programs can be acquired in advance. That is, by reading “episode_number” shown in FIG. 5, it is possible to determine whether or not the program corresponding to the series descriptor is a program that is continuously broadcast. Thereby, it can be determined whether or not the corresponding program is a continuous program. Further, by reading “last_episode_number”, it is possible to determine how many episodes the corresponding program is in.

  It should be noted that the electronic program guide data as described above may be acquired by downloading from a predetermined server on the network via the external connection interface 11, and information relating to the continuous program may be acquired. Information about the acquired continuous program is stored in the RAM 15, for example.

  Next, a user interface used in the process of reading a program by the CPU 10 will be described. The user interface used in the process of the program is not particularly limited. For example, a remote control device 18 having an LCD (Liquid Crystal Display) and operation keys can be used. In the following description, the operation menus by the OSD can be operated by the remote control device 18, respectively.

  The recording / reproducing apparatus 1 can automatically record a program that matches the set keyword condition from data in the electronic program guide. Of course, not the automatic recording but the reserved recording in which the user designates and reserves the program to be recorded by himself / herself is also possible. FIG. 6 is an example of an operation menu used for keyword setting. The keyword can be freely set by the user, such as a person name or a place name. Here, a case where a keyword is selected from a program genre prepared in advance will be described.

  The keyword setting screen 30 includes a keyword candidate part 31, a selected keyword part 32, and an action selection part 33. The keyword candidate section 31 displays keyword candidates of program genres such as “movie” and “continuous drama” that can be set as keywords. A genre surrounded by a thin line indicates that it has been selected. In the selected keyword part 32, the selected keyword is displayed. The operation selection unit 33 displays commands for determining keyword registration, deregistration, and the like, such as “registration” and “cancel”.

  The user can register the selected genre as a keyword by selecting a genre to be automatically recorded from the keyword candidate section 31 and selecting “Register” in the operation selecting section 33, and the registered genre is the selected keyword section 32. Is displayed. In this example, “music”, “soccer”, “night news”, “continuous drama”, and “variety” are registered as keywords.

  The recording / reproducing apparatus 1 compares the keyword and the data of the electronic program guide, and stores information related to the program meeting the keyword condition in the RAM 15 or the hard disk 8 as scheduled recording program data. This scheduled recording program data is obtained from the data of the electronic program guide, and is used when displaying scheduled recording candidates. The scheduled recording program data is stored in the RAM 15 or the hard disk 8 as recorded program information after recording.

  As an example, a recording reservation candidate display screen 40 as shown in FIG. 7 is displayed. The recording reservation candidate display screen 40 includes a time display unit 41, a recording reservation candidate list 42, an operation selection unit 43, and a message unit 44. The time display unit 41 displays the current date and time.

  The recording reservation candidate list 42 displays a list of recording reservation candidates that are scheduled to be broadcast from now on and show program names that match the keyword “continuous drama”. Every time the recording reservation candidate list screen 40 is displayed, the recording reservation candidate list 42 compares the latest electronic program guide data with registered keywords, and displays programs that match the keywords according to the display format. To sort and display. The display format can be switched as desired by the user, such as in time order or by genre. In this example, programs are displayed in time order (ascending order from bottom to top). The list of recording reservation candidates is scrolled with the up and down keys. The hatched lines (“Drama F (4th)”) are currently specified programs from the list of recording reservation candidates.

  The operation selection unit 43 displays operation commands such as “decide” and “view”. By selecting “Determine”, it is possible to select to confirm or cancel the recording reservation of the program specified in the list of recording reservation candidates. By selecting the confirmation, the user can confirm the recording reservation of the program that he / she wants to record reliably from the recording reservation candidates. Also, by selecting cancel, it is possible to cancel a recording reservation for a program that is deemed unnecessary. Even if the recording reservation is not confirmed, the program shown in the list of recording reservation candidates is automatically recorded, but it is only a candidate for recording reservation, and the recording priority is confirmed for recording reservation. The setting is lower than the program. A program whose recording reservation has been confirmed disappears from the list of recording reservation candidates, and is treated as a reserved recording by the user's designation. The program whose recording reservation has been canceled disappears from the list of recording reservation candidates, but if the canceled program is a continuous program, the recording / playback apparatus 1 records the program.

  By selecting “View”, the display of the recording reservation candidate display screen 40 is terminated.

  The program information display unit 44 is for displaying detailed information such as the broadcast time, broadcast station name, performer, and special notes of the program specified in the list of recording reservation candidates.

  With reference to the flowchart shown in FIG. 8, an example of the operation of the recording reservation candidate deletion process performed by the CPU 10 will be described. The recording reservation candidate deletion process is to delete a program that is a candidate for recording reservation from the list of automatic recording programs. FIG. 8 shows an example of the procedure of the recording reservation candidate deletion process. The recorded program reservation process shown in FIG. 8 is executed when the user uses the remote control device 18 to instruct the recording / reproducing apparatus 1 to display the recorded program list screen shown in FIG.

  In the recording reservation candidate erasure process, first, it is determined whether or not an operation for displaying the recording reservation candidate list 42 is selected according to a user instruction (step S1). If it is determined in step S1 that the display operation has not been selected, the recording reservation candidate erasure process is terminated. If it is determined in step S1 that the display operation has been selected, the scheduled recording program data stored in the hard disk 8 or the RAM 15 is read out, and the scheduled recording candidate display screen shown in FIG. 40 is generated and the recording reservation candidate list 42 is displayed (step S2).

  Next, it is determined whether or not the user has deleted the program from the recording reservation candidate list 42, that is, whether or not the recording reservation has been canceled (step S3). If it is determined in step S3 that the recording reservation candidate has not been deleted, the recording reservation candidate deletion process is terminated. If it is determined in step S3 that the program has been deleted, it is determined whether the deleted program is a continuous program (step S4). Whether or not the program is a continuous program can be determined by reading the information on the continuous program described above.

  If it is determined in step S4 that the program is not a continuous program, the process proceeds to step S6. If it is determined in step S4 that the program is a continuous program, even if the program has been deleted by the user, a recording reservation is made as a recording target program and a viewing invitation screen shown in FIG. After the reservation candidate is stored (step S5) by storing the target continuous program flag, the process proceeds to step S6.

  In step S6, the display of the program deleted from the recording reservation candidate list 42 is deleted, and a non-display flag in the recorded program list shown in FIG. Next, it is determined whether or not the user cancels the display of the recording reservation candidate display screen 40 (step S7). If it is determined in step S7 that the display has not been canceled, the processes in steps S3 to S7 are repeated. If it is determined in step S7 that the display has been canceled, the recording reservation candidate deletion process is terminated.

  There is an upper limit to the data capacity of the recording destination recording device such as the hard disk 8. Therefore, the recording / reproducing apparatus 1 compares the data capacity of the recording destination recording apparatus with the data capacity of the recording destination recording apparatus required for the program scheduled to be recorded by the recording reservation, and the data capacity of the recording destination recording apparatus. When there is not enough, it is possible to automatically delete old programs recorded by automatic recording as necessary. It should be noted that automatic deletion of old programs recorded by automatic recording may be performed for programs that have passed a predetermined time from the recording date and time.

  The retention period excess processing is to delete a program with such a priority that an unviewed continuous program is left in such automatic deletion. It should be noted that programs recorded by the user specifying a program by themselves instead of automatic recording are basically not subject to automatic erasure, but are preferentially stored over unviewed continuous programs by automatic recording.

  With reference to the flowchart shown in FIG. 9, an example of the operation of the retention period excess processing performed by the CPU 10 will be described. In the storage period excess processing, first, the latest electronic program guide information is acquired (step S11). Next, the recording reservation candidates are extracted (step S12), and the data capacity required for the recording destination recording device such as the hard disk 8 is calculated (step S13).

  Then, it is determined whether or not the capacity of the recording destination recording device is insufficient (step S14). If it is determined in step S14 that the capacity is sufficient, the storage period excess processing ends. If it is determined in step S14 that the capacity is insufficient, target programs for sequential automatic deletion are extracted from old programs recorded by automatic recording (step S15).

  Next, it is determined whether the target program is a continuous program (step S16). If it is determined in step S16 that the program is not a continuous program, it is set as a target program for automatic erasure (step S17). Then, the process returns to step S14. That is, the processes from step S14 to step S18 are repeated until the capacity of the hard disk 8 necessary for the recording reservation candidate program can be secured. If it is determined in step S16 that the program is a continuous program, the retention period is extended or automatic deletion non-target is set (step S18). Then, the process returns to step S14.

  By executing this storage period excess processing, the continuous recording period can be extended for the continuous program, so that it can be preferentially stored over programs other than the continuous program, and overlooked.

  In the recorded program viewing / presentation process, when a continuous program is viewed or reserved for recording in the middle of the program, it is presented to the user that the past program of the continuous program has been recorded by automatic recording, and the viewing is encouraged. . The program to be presented is basically an unviewed program. The recorded program viewing and presenting process is executed when the user views a program or makes a recording reservation.

  With reference to the flowchart shown in FIG. 10, an example of the operation of the recorded program viewing presentation process performed by the CPU 10 will be described. The recorded program viewing / presenting process is for a case where a recording reservation is made. In the recorded program viewing presentation process, first, it is determined whether or not a recording reservation instruction has been made, that is, whether or not the user has confirmed the reservation of the program while the recording reservation candidate display screen 40 shown in FIG. 7 is being displayed. (Step S21). If it is determined in step S21 that the recording reservation instruction has not been given, the recorded program viewing and presentation process ends. If it is determined in step S21 that an instruction for recording reservation has been made, the instructed program is a continuous program in which the recording reservation has been canceled in the past, that is, in step S5 of the recording reservation candidate deletion process shown in FIG. It is determined whether or not the processed program is a continuous program (step S22).

  If it is determined in step S22 that the program is not a continuous program for which the recording reservation has been canceled, the recorded program viewing and presentation process ends. If it is determined in step S22 that the program is a continuous program for which the recording reservation has been canceled, a user interface (UI) screen is generated and displayed (step S23), and the user can view past recorded programs for the user. An inquiry is made as to whether or not to do so (step S24).

  FIG. 11 shows an example of a user interface screen displayed when making an inquiry. The presentation screen 50 includes an operation selection unit 51 and a message unit 52. The operation selection unit 51 displays an operation command for selecting whether or not the user views an unviewed time, such as “Yes” and “No”. When “Yes” is selected, the times broadcast in the past are reproduced. If “No” is selected, the screen returns to the recording reservation candidate display screen 40 shown in FIG. The message part 52 is for presenting to the user that there are unviewed times by a message such as “Do you want to play the times broadcast in the past?”. Note that the screen shown in FIG. 11 is created based on the target continuous program flag described above.

  In this example, the “drama F” deleted from the recording reservation candidate when the user broadcasts before the fourth time is displayed on the recording reservation candidate display screen 40 shown in FIG. When the recording reservation is confirmed, the fact that there is a past broadcast is presented and an inquiry is made as to whether or not to reproduce.

  If it is determined in step S24 that the program is viewed, the corresponding past series of programs is played back (step S25), and the recorded program viewing presentation process is terminated. This reproduction is performed, for example, from the oldest program among the recorded continuous programs. Information relating to the number of programs can be recognized by reading information relating to continuous programs. If it is determined in step S24 that the program is not viewed, a flag for displaying the corresponding continuous program as a list when the user selects a recorded program list is set (step S26). The viewing presentation process ends. Thereafter, when the user selects the recorded program list, the continuous programs with this flag set are displayed in the list.

  The recorded program viewing / presentation process allows the user to know that the past broadcast of the program has been secretly recorded and to play back the past broadcast when the program is viewed or reserved for recording.

  In the recorded program list display process, when a continuous program is recorded halfway through, the user is presented with the fact that the past program of the continuous program has been recorded by automatic recording and encourages viewing. The program to be presented is basically an unviewed program. The recorded program list display process is executed when the user tries to reproduce a recorded program.

  With reference to the flowchart shown in FIG. 12, an example of the operation | movement of the recorded program list display process which CPU10 performs is demonstrated. First, in the recorded program list display process, it is determined whether or not the user has selected to display a list of recorded programs (step S31).

  FIG. 13 is an example of a recorded program list display screen. The recorded program display screen 60 includes a genre selection unit 61, a recorded program list 62, and an operation selection unit 64.

  The reproduction program selection unit 61 selects a genre of recorded programs such as “drama” and “sports”. The recorded program list 62 displays a list of recorded programs. An unviewed program (“Drama F (4th)” in the example shown in FIG. 13) is marked with a mark [NEW] for identifying that it has not been viewed. The identification mark disappears when the program is reproduced. The display format of the list of recorded programs can be switched as desired by the user, such as in time order or by genre. In this example, recorded programs of the genre “drama” are displayed in time order (in ascending order from bottom to top). The list of recorded programs is scrolled with the up and down keys. The hatched lines (“Drama F (4th)”) are currently specified programs from the list of recorded programs.

  The operation selection unit 64 displays operation commands such as “decide” and “view”. By selecting “determine”, it is possible to select reproduction or deletion of a program specified in the list of recorded programs. The user can reproduce and view the program by selecting reproduction. After the reproduction, the display of the identification mark “NEW” of the reproduced program disappears. Moreover, the program can be deleted by selecting the deletion. By selecting “View”, the display of the recorded program display screen 60 is terminated.

  If it is determined in step S31 that display of the recorded program list is not selected, the recorded program list display process is terminated. If it is determined in step S31 that display of the recorded program list has been selected, the recorded program information is read from the storage device such as the RAM 15 or the hard disk 8.

  Next, the non-display flag set in step S6 of the above-described recording reservation candidate deletion process is referred to from the read program data to determine whether the program is a non-display target program (step S33).

  If it is determined in step S33 that the program is a non-display target program, the data of the program is deleted from the display data, and the recorded program list display process is terminated. If it is determined in step S33 that the program is a display target program, data of unviewed continuous programs that are secretly reserved for recording and automatically recorded retroactively are displayed in the list of recorded programs. The recorded program list display process is terminated. In the example shown in FIG. 13, “Drama F” is set as a display target, and “Drama F (4th)” and “Drama F (4th)” are recorded together with “Drama F (4th)” by recording. “Drama F (1st) to Drama F (3rd)”, which is the past broadcast of viewing, is displayed in the recorded program list 62.

  With this recorded program list display process, when playing back a recorded program, the user knows that the past broadcast of the program has been secretly recorded, and can play back and watch the past broadcast. .

  As described above, according to the recording / reproducing apparatus 1 according to this embodiment, when a program is a continuous program, the program is recorded even if it is not subject to recording reservation, and the user can record the continuous program. When viewing or recording reservation is made in the middle, it can be shown to the user that there is a recorded program that has not been viewed for the past broadcast, and playback can be prompted. Further, when a user records and reproduces a continuous program by recording reservation from the middle, it can be shown to the user that there is an unviewed recorded program for the past broadcast, and reproduction can be prompted. Therefore, it is possible to prevent the continuous program from being overlooked and to comfortably view the continuous program.

In the case where the output unit is a recording / reproducing device built in the television receiver, the output unit may directly output the video signal and the audio signal to an output device such as a display. Further, the video signal and the audio signal may be output from an external output terminal.

  Moreover, in the recording / reproducing apparatus 1 mentioned above, although the information regarding a continuous program was acquired from the data of an electronic program guide, you may acquire the information regarding a continuous program directly from networks other than an electronic program guide, for example.

  In the recording / reproducing apparatus 1 described above, a program is automatically recorded in accordance with a keyword set in advance by the user. However, if the recording apparatus at the recording destination has sufficient capacity, a continuous program is designated for automatic recording. Regardless of the presence or absence, all may be recorded automatically.
