  The program recording / playback apparatus 100 includes a D / A converter 108, an LCD (Liquid Crystal Display) 109, a switch (SW) 110, and a memory 111.

  The program recording / playback apparatus 100 further includes a CPU 112, an HDD 113, a USB (Universal Serial Bus) port 114, a card slot 115, an EPG decoding unit 116, a communication I / F 117, and a LAN terminal 118.

  The first and second digital tuners 101 and 102 are supplied with broadcast waves received by the terrestrial digital broadcast antenna AT. The digital tuners 101 and 102 each perform reception processing for selecting and receiving a signal component of a predetermined frequency corresponding to the designated channel from the broadcast wave supplied from the antenna AT, and perform first and second demodulation circuits. 103 and 104.

  Here, the first digital tuner 101 is a receiving means for receiving a broadcast wave of 12-segment broadcast, and the second tuner 102 is a receiving means for receiving a broadcast wave of 1-segment broadcast. In addition, the 12-segment broadcast is a terrestrial digital broadcast that uses 12 segments of one channel divided into a plurality of segments (13 segments), and a 1-segment broadcast is a terrestrial digital broadcast that uses one segment.

  The first and second OFDM demodulation circuits 103 and 104 perform predetermined demodulation processing on the signal components extracted by the first and second digital tuners 101 and 102, respectively, and further perform error correction processing and the like. , Each generates program data (specifically, a transport stream). The generated program data (transport stream) is input to the first and second decoding circuits 105 and 106, respectively.

  The first and second decoding circuits 105 and 106 perform a decoding process on the input transport streams to generate a digital video signal and a digital audio signal. Here, the first decoding circuit 105 is for 12-segment broadcasting, and the second decoding circuit 106 is for 1-segment broadcasting.

  The OSD circuit 107 superimposes an OSD (On Screen Display) signal on the input digital video signal and outputs it to the D / A converter 108. This OSD signal is generated by the CPU 112.

  The D / A converter 108 converts the input digital video signal into an analog video signal and outputs the analog video signal. The LCD panel 109 is video display means for displaying video of a program being viewed using an analog video signal.

  The switch 110 has various operation switches, and the memory 111 has RAM, ROM, and the like. In the ROM, a control program and a program executed by the CPU 112 are written. The RAM can provide a work area necessary for the CPU 112 to execute the program.

  The CPU 112 controls the above-described modules in accordance with a control program stored in the memory 111 to control video display and audio output. The CPU 112 operates in accordance with a program recording program to be described later and has a function as a program recording control means for controlling simultaneous recording of a mobile program described later. The CPU 112 uses the program data demodulated by the first and second OFDM demodulation circuits 103 and 104 when simultaneously recording a mobile program.

  An HDD (Hard Disk Drive) 113 has a function as recording means for recording data demodulated by the first and second OFDM demodulation circuits 103 and 104 as terrestrial digital broadcast program data.

  The USB port 114 can be connected to the connector of the USB cable 203. An HDD 201 for USB connection is connected to the USB port 114 via a USB cable 203.

  The card slot 115 is inserted with a memory card 202 such as an SD memory card (Secure Digital memory card), and reads / writes data from / to the inserted memory card 202. The memory card 202 stores program data for the mobile terminal device 250 and the like.

  The mobile terminal device 250 is a mobile receiver, and is, for example, a mobile phone capable of viewing a digital terrestrial broadcast program, a PDA (Personal Digital Assistants), a mobile music player, or the like.

  The EPG decoding unit 116 separates and extracts EPG data described later from the program data demodulated by the first and second OFDM demodulation circuits 103 and 104.

  The communication I / F 117 performs information transmission with a device (for example, a LAN compatible HDD 202) connected to the LAN terminal 118.

  The LAN terminal 118 is used as a general LAN-compatible port using Ethernet. The LAN terminal 118 is used to connect devices such as a LAN-compatible external HDD 204 and perform information transmission with these devices.

  Next, simultaneous recording of a mobile program in the program recording / playback apparatus 100 having the above configuration will be described with reference to FIGS. FIG. 2 is a flowchart showing the operation procedure of the simultaneous recording process of the mobile program according to the program recording program by the CPU 112, and FIG. 3 is a flowchart showing the operation procedure of another simultaneous recording process. The CPU 112 executes the operation according to the flowchart shown in FIG. 2 or FIG.

  Here, the simultaneous recording of the mobile program in the program recording / playback apparatus 100 means that the program data of the 12-segment broadcast program (hereinafter, “12-segment program data”) when the 1-segment broadcast is a 12-segment broadcast simultaneous broadcast. This means that the program data for the portable terminal device 250 is recorded by simultaneously recording the program data of the one-segment broadcast program (hereinafter referred to as “1 segment program data”) on the HDD 113. .

  When the CPU 112 is instructed to perform recording of a digital terrestrial broadcast program by a predetermined operation using a switch provided in the switch 110 or a remote controller 400 described later, the CPU 112 follows the flowchart shown in FIG. Perform simultaneous recording processing.

  When the CPU 112 starts the simultaneous recording process, the CPU 112 refers to EPG (Electronic Program Guide) data of 1 segment broadcast and EPG data of 12 segment broadcast acquired from the EPG decoding unit 116 (S1).

  Here, the EPG data is electronic program information. The program recording / playback apparatus 100 can display an electronic program guide 120 as shown in FIG. 14, for example, on the LCD 109 by separating SI described later from the broadcast signal and using EPG data included in the SI.

  In digital broadcasting, EPG data is superimposed on a broadcast signal as service information (SI). The SI includes information necessary for viewing a digital broadcast program and an event information table (EIT), and EPG data is included in the EIT.

  The EPG data includes, for example, program name (program title), program genre, program start time, program end time, program content data, and the like. In S2, which will be described later, by comparing the program name data, it can be determined whether or not the 1-segment broadcast is a 12-segment broadcast simultaneous broadcast.

  Next, the CPU 112 compares the EPG data of the 1 segment broadcast and the EPG data of the 12 segment broadcast and operates as a determination unit, and determines whether or not the 1 segment broadcast is a 12 segment broadcast simulcast. (S2).

  For example, as described above, the CPU 112 may perform simultaneous determination based on at least a comparison result of program name data, but may perform determination based on at least one of a program name, a program genre, or a broadcast time. Good. When the program name, the program genre, and the broadcast time match, the probability of simulcasting increases. Therefore, the use of the program name, program genre, and broadcast time enables accurate simulcast determination. In this case, the CPU 112 may determine that the broadcast is a simulcast if the program name or the like is a complete match, but determines that the broadcast is a simulcast if the match is not complete, for example, a partial match with a similarity of 90% or more. May be.

  The CPU 112 proceeds to S3 when determining that the 1-segment broadcast is a 12-segment broadcast simultaneous broadcast, but proceeds to S4 when determining that the 1-segment broadcast is not a 12-segment broadcast simultaneous broadcast.

  When the CPU 112 proceeds to S3, it performs simultaneous recording processing, and records the 12-segment program data and the 1-segment program data determined to be the 12-segment broadcast simulcast together in the HDD 113. Here, the 12-segment program data and the 1-segment program data are simultaneously recorded on the HDD 113. For example, the recording start time is simultaneously set, and the recording start time of the 1-segment program data is slightly delayed from the 12-segment program data. The recording may be recorded on the HDD 113 so that the recording end times are the same. Here, the CPU 112 performs an operation as identification data recording control means. When recording 12-segment program data, identification data indicating that it is 12-segment program data is recorded on the HDD 113, and when recording 1-segment program data, identification data indicating that it is 1-segment program data is recorded on the HDD 113. To record.

  When proceeding to S4, the CPU 112 performs a single recording process and records only 12-segment program data in the HDD 113. When executing S3 or S4, the CPU 112 ends the simultaneous recording process of the mobile program.

  When the program recording / playback apparatus 100 executes the simultaneous recording process of the mobile program as described above, when the 1-segment broadcast is a 12-segment broadcast simultaneous broadcast, the 12-segment program data and 1 of the simultaneous broadcast are displayed. The segment program data is automatically recorded on the HDD 113. At this time, since the program data recorded on the HDD 113 is 12-segment program data and 1-segment program data of the simulcast, both program data are the same program data. Therefore, the program recording / playback apparatus 100 can reliably record 12-segment program data and 1-segment program data of the same program to record a program for mobile use. Therefore, since high-rate program data and low-rate program data of the same program can be held, both can be used properly without re-encoding.

  In this case, for example, only the 1-segment program data is moved from the HDD 113 to the memory card 202, and the memory card 202 is attached to the portable terminal device 250, so that the same program as the 12-segment broadcast program is used by the portable terminal device 250. Can watch.

  Since the 12-segment program data has a data size larger than that of the 1-segment program data, it is not suitable for moving to the memory card 202 and viewing the program on the mobile terminal device 250. On the other hand, since 1-segment program data has a lower rate than 12-segment program data, it is not suitable for program playback on the program recording / playback apparatus 100. However, program data of the same program may not be recorded only by recording 12-segment program data and 1-segment program data at the same time.

  Therefore, the program recording / playback apparatus 100 performs simulcast determination as described above, and when it is determined to be simulcast, 12-segment program data and 1 seg program data determined to be simulcast Are simultaneously recorded in the HDD 113.

  On the other hand, the flowchart shown in FIG. 3 is different from the flowchart shown in FIG. 2 in that S5 and S6 are executed between S2 and S3.

  When the CPU 112 proceeds from S2 to S5, the recording setting screen 300 described later is displayed on the LCD 109. In the subsequent step 6, it is determined whether or not 1 segment recording is selected on the recording setting screen 300. If it is selected, the process proceeds to S3, and if not, the process proceeds to S4. The other steps are the same as in FIG.

  As shown in FIG. 4, the recording setting screen 300 has an input unit 301 for inputting presence / absence of 1-segment recording, and the viewer can input presence / absence of 1-segment recording using the input unit 301. FIG. 4A shows a case where 1 segment recording is performed, and FIG. 4B shows a case where 1 segment recording is not performed. If there is 1 segment recording, the process proceeds from S6 to S3. If it is determined that the broadcast is simultaneous broadcasting, 1 segment program data and 12 segment program data are simultaneously recorded in the HDD 113.

  Thus, according to the flowchart shown in FIG. 3, when the simultaneous recording process for the mobile program is executed, the viewer can select the presence / absence of the 1-segment recording, and the simultaneous recording of the mobile program can be selected by the viewer. It will be executed according to the contents.

  By the way, the 12-segment program data recorded by the simultaneous recording process of the program for mobile and the 1-segment program data are different from each other in devices suitable for reproduction. It is difficult to improve.

  For this reason, the program recording / playback apparatus 100 executes operations in accordance with the flowcharts shown in FIGS. In the program recording / playback apparatus 100, the CPU 112 performs an operation as an association unit. Then, the CPU 112 has a 12-segment file for recording the 12-segment program data on the HDD 113 (fixed receiver file) or a 1-segment file for recording the 1-segment program data on the HDD 113 (mobile receiver file). Is generated as follows to associate the 1-segment program data with the 12-segment program data.

  In the case of simultaneous recording of a program for mobile, the 12-segment program data and the 1-segment program data are recorded in the HDD 113 by being associated with each other by a file name.

  When the CPU 112 starts the association process according to the flowchart of FIG. 5, the process proceeds to S11, where it is determined whether or not the 12-segment recording records 12-segment program data. If 12-segment recording, the process proceeds to S12, otherwise proceeds to S16. . In S12, a file name of a 12-segment file is generated. As will be described later, the file name includes a file name body and an extension (a character string for identifying the file type). In S12, the extension is generated with content specific to 12-segment broadcasting (content dedicated to 12-segment broadcasting).

  Next, when the operation proceeds to S13, the CPU 112 determines whether or not to perform the simultaneous recording process (S3). The CPU 112 proceeds to S14 when performing the simultaneous recording process, and proceeds to S15 otherwise. In S <b> 14, the CPU 112 stores, in the HDD 113, data indicating that 1-segment program data is present (1-segment recording is present) as management data for managing whether or not 12-segment program data includes 1-segment program data for simulcast. In step S15, data indicating no 1-segment recording is recorded in the HDD 113 as management data, and the association process is terminated. The CPU 112 operates as management data recording control means when executing S14 and S15.

  On the other hand, when the operation proceeds from S11 to S16, the CPU 112 determines whether or not to perform the simultaneous recording process (S3) as in S13. The CPU 112 advances the operation to S17 when performing the simultaneous recording process, and advances the operation to S18 otherwise. In S17, the CPU 112 generates a file name of the 1-segment file. In this case, the CPU 112 generates a file name in which the file name of the corresponding 12-segment file is the same as the file name body and the extension is different. In S17, the extension is generated with content specific to one segment broadcast (content dedicated to one segment broadcast).

  In S <b> 18, the CPU 112 generates a file name using a file name body corresponding to a single segment broadcast program recorded alone and an extension unique to the one segment broadcast. When S17 or S18 is executed, the association process is terminated.

  When simultaneous recording of a mobile program is performed by performing association processing as described above, for example, the file name 310 shown in FIG. 8 is attached to the 12-segment file, and the 1-segment file is A file name 320 is attached. The file name 310 has a file name body 311 and an extension 312, and the file name 320 has a file name body 311 and an extension 313.

  The file name 310 and the file name 320 have the same file name body 311 (“toshipp ppp 0900” in FIG. 8). The extension 312 is a character string unique to 12-segment broadcasting (for example, it can be “dtv” as shown in FIG. 8), and the extension 313 is a character string unique to 1-segment broadcasting (for example, “seg”). It can be.

  Since the file name 310 and the file name 320 are different only in extension and have the same file name body 311, a 12-segment file and a 1-segment file must be associated with each other. Becomes clear. In addition, since the extensions 312 and 313 are character strings unique to 12-segment broadcast or 1-segment broadcast, respectively, it is clear from the file name whether the program data is 12-segment broadcast or 1-segment broadcast. The viewer can determine which program data is only by looking at the file name.

  In the program recording / playback apparatus 100, since the 12-segment file and the 1-segment file are associated with each other as described above, operations such as moving and deleting the 12-segment file are operations for the 1-segment file. Can be linked. Therefore, the usability of the viewer can be improved.

  For example, when the screen is changed from a program list 350 for 12-segment broadcasting, which will be described later, to a program list 360 for 1-segment broadcasting, the cursor is moved to the program associated with the program on which the cursor is placed in the program list 350. Hit it.

  In the program list 350, when the program data is instructed to be moved or copied, the program data associated with the program data instructed to be moved or copied in the program list 350 when the screen is changed to the program list 360 is displayed. Move or duplicate.

  Furthermore, when the program list 350 is instructed to delete program data and the screen is changed to the program list 360, the program data associated with the program data instructed to be deleted in the program list 350 is deleted.

  When the program list 350 is instructed to lock or unlock the program data and then the screen is changed to the program list 360, the program data associated with the program data instructed to be locked or unlocked is locked or unlocked. To do.

  The program recording / playback apparatus 100 can display the program list 350 by operating according to the flowchart of FIG.

  When the CPU 112 starts the program list display process according to the flowchart of FIG. 6, the CPU 112 proceeds to S <b> 21 and refers to the program data file recorded in the HDD 113. The program data file includes a 12-segment file or a 1-segment file. Subsequently, the CPU 112 proceeds to S22, and determines whether or not the extension of the file name of the referred program data file is unique to the 12-segment broadcast. In that case, the operation proceeds to S23, and otherwise proceeds to S26. In this way, the program data file with an extension of one segment broadcast is not displayed in the program list 350.

  In S23, it is determined whether the management data is 1 segment program data or not. If there is 1 segment program data, the operation proceeds to S24, and if not, the operation proceeds to S25.

  In S24, program detail data having a 1-segment icon 351a described later is generated, and in S25, program detail data without a 1-segment icon is generated. In S26, it is determined whether or not the reading of the program data file is finished. If finished, the process returns to S27, and if not, the process returns to S21.

  If it progresses to S27, the program list 350 will be displayed using the program detailed data produced | generated by S24 or S25, and a program list display process will be complete | finished. The program recording / playback apparatus 100 records management data by executing S14 and S15, and refers to the management data in S23. In this way, the presence / absence of 1-segment program data is determined more easily than when all 12-segment program data is referenced.

  The program recording / playback apparatus 100 can display the program list 360 by operating according to the flowchart of FIG.

  When the CPU 112 starts the program list display process according to the flowchart of FIG. 7, the CPU 112 proceeds to S <b> 31 and refers to the program data file recorded in the HDD 113. Subsequently, the CPU 112 proceeds to S32, and determines whether or not the extension of the file name of the referred program data file is unique to the one-segment broadcast. If so, the operation proceeds to S33, and if not, the operation proceeds to S34. In this way, only the program data file whose extension is unique to one segment broadcast is displayed in the program list 360.

  In S33, program details data is generated. In S34, it is determined whether or not the reading of the program data file is finished. If finished, the process returns to S35, and if not, the process returns to S31.

  If it progresses to S35, the program list 360 will be displayed using the program detailed data produced | generated by S33, and a program list display process will be complete | finished.

  The program list 350 is a list of recorded programs of 12 segment broadcast, and has a program specification 351 and a program specification 352 as shown in FIG. 9, for example. The program details 351 has a 1-segment icon 351a. The 1-segment icon 351a indicates that 1-segment program data of the simulcast is recorded in the HDD 113 in addition to the 12-segment program data by performing the simultaneous recording process. Therefore, the program details 351 corresponds to the file name of the 12-segment file recorded by executing S3 and S14 described above. Further, since the program details 352 does not have a 1-segment icon, only 12-segment program data is recorded in the HDD 113. Therefore, the program details 352 corresponds to the file names of the 12-segment files recorded by executing the above-described S4 and S15.

  Thus, depending on whether or not there is a 1-segment icon 351a in the program details displayed in the program list 350, the viewer records 1-segment program data of the same program in addition to 12-segment program data, or It can be confirmed that only 12-segment program data is recorded.

  The program list 360 is a list of recorded programs of one segment broadcast, and has a program specification 361 and a program specification 362 as shown in FIG. Among these, the program details 361 is “sports news” having the same program name as the program details 351. Therefore, the viewer can confirm from the program list 360 that the same program as the 12-segment broadcast is being recorded for the one-segment broadcast. The program details 361 corresponds to the file name of the 1-segment file recorded by executing the above-described S3 and S14. The program details 362 corresponds to the file name of a one-segment file recorded alone.

  Then, the viewer moves the cursor to the program details 351, 352, the program details 361, and the program details 362 on the program list 350, and presses the play button 401 of the remote control 400 shown in FIG. The CPU 112 reads out the corresponding program data from the HDD 113 and reproduces the recorded program.

  In this case, the CPU 112 operates as a reproduction control unit and operates according to the flowchart shown in FIG. 12, so that the reproduced video is displayed depending on which of the 12-segment program data and the 1-segment program data is used. Change the size (called video size) and play the program.

  When starting the reproduction control process, the CPU 112 reads program data corresponding to the reproduction instruction from the reproduction button 401 from the HDD 113 (S41). Next, identification data corresponding to the read program data is read from the HDD 113 (S42). Next, the CPU 112 performs an operation as data determination means, and determines whether or not the identification data is data indicating 1-segment program data (S43). The CPU 112 proceeds to S44 when the identification data indicates 1-segment program data, and proceeds to S45 otherwise. In S44, the reproduction mode data for determining the mode for reproducing the program is set to the partial screen mode, and in S45, the reproduction mode data is set to the full screen mode. In subsequent S46, the CPU 112 performs an operation as a reproduction control means, and when the program is reproduced according to the set reproduction mode data, the reproduction control process ends.

  When the program is reproduced in the full screen mode, the video is displayed using the entire display screen 400 of the LCD 109 shown in FIG. When the program is reproduced in the partial screen mode, the program is reproduced by displaying the video only in the reproduction area 401 for 1 segment. A portion other than the playback area 401 is displayed in black where no video is displayed. A playback area 401 is a playback area for a mobile receiver, including the center P of the display screen 400. The playback area 401 is smaller than the display screen 400 and is set to a size that does not make the image roughness noticeable. . Here, the playback area 401 is set to an area including the center P, but may be set to an area not including the center P such as the right end and the left end.

  Since 1-segment program data has a lower rate and a smaller number of pixels than 12-segment program data, it is suitable for being played back on a smaller screen than a fixed receiver. For this reason, it is not preferable to display the video on the entire display screen 400 using the 1-segment program data as it is, since the roughness of the video becomes conspicuous. Therefore, the program recording / playback apparatus 100 plays back the program by changing the video size depending on whether or not the program data is 1-segment program data. When the program data is 12-segment program data, the entire display screen 400 is used to display the video, and the program data is reproduced by displaying a fine and beautiful video on a large screen while the program data is 1-segment program data. In such a case, the video is displayed only in the reproduction area 401 smaller than the entire display screen 400 so that the program can be reproduced without noticeable roughness.

  In the above embodiment, a television with a recording function provided with an image display means for displaying an image of a digital terrestrial broadcast program and a program recording control means for recording the program will be described as an example. Yes. However, the present invention can also be applied to a program recording / playback apparatus such as a DVD recorder or an HDD recorder that does not include video display means.

  In addition, the program recording / playback apparatus 100 according to the above embodiment includes receiving means for receiving a 1-segment broadcast program and receiving means for receiving a 12-segment broadcast program. The receiving means only needs to be able to receive broadcasts for mobile receivers or broadcasts for fixed receivers, and may include receiving means for receiving broadcasts of a different system from 1-segment broadcasts and 12-segment broadcasts. For example, receiving means for receiving a broadcast for mobile receivers and a broadcast for fixed receivers that are performed without dividing the frequency band of one channel into segments may be used.

  The above description is the description of the embodiment of the present invention, and does not limit the apparatus and method of the present invention, and various modifications can be easily implemented. In addition, an apparatus or method configured by appropriately combining components, functions, features, or method steps in each embodiment is also included in the present invention.
