(First embodiment)
The first embodiment will be described with reference to FIGS. FIG. 3 is a state transition diagram showing an example of the first recording / reproducing control according to the first embodiment, and FIG. 4 is a flowchart showing an example of the first recording / reproducing control according to the first embodiment. FIG. 5 is a flowchart showing an example of a part of the process of the first recording / reproducing control according to the first embodiment.

  For example, when the HDD 100 is connected via the first USB terminal 124, the control module 110 (recording / reproduction area management module 1105) detects the connection of the HDD 100, recognizes the HDD 100, and the first storage area of the HDD 100. (For example, all areas) are formatted for loop recording / reproduction, HDD 100 connection processing is executed, and the first storage area (HDD 100) is managed as a data processing area (loop recording / reproduction area). Note that the first recording area includes a plurality of divided areas managed by a plurality of addresses.

  Based on the recording control information stored in the nonvolatile memory 1103, the control module 110 (recording / playback control module 1104) corresponds to each program data (video and audio of each program) corresponding to each broadcast signal received by the tuners 1031 to 1038. Data) is loop-recorded in the first storage area (HDD 100).

  For example, when the recording control information is control information for instructing to continuously record the programs of the channels 101 to 108, the control module 110 (recording / reproducing control module 1104) performs tuners 1031 to 1038 based on the recording control information. Control is performed so that each program data corresponding to each broadcast signal received in is recorded in a loop in the first storage area (HDD 100). In response to this, the HDD 100 records each program data corresponding to each broadcast signal received by the tuners 1031 to 1038 in a loop.

  For example, by loop recording control of the control module 110 (recording / playback control module 1104), the HDD 100 starts recording program data from the first area (address 0001) of the first storage area and the last area ( The program data is continuously recorded up to the address XXX), the program data is recorded again from the head area (address 0001), and the program data is continuously recorded up to the last area (address XXXX).

  That is, after the program data is recorded from the first area to the last area of the first storage area, there is no empty area in the first storage area, so the HDD 100 moves from the first area to the last area of the first storage area. Instead of deleting the already recorded program data, new program data is recorded from the first area to the last area of the first storage area. Such recording of program data is referred to as loop recording. That is, the latest program data corresponding to the storage size of the first storage area is always accumulated by loop recording.

  For example, as shown in S11 and S12 of FIG. 3, program data is recorded in the order of the area 1-2 and the area 1-1 of the first storage area, and thereafter, as shown in S13 and S14 of FIG. Data recording proceeds.

  Further, the control module 110 (recording / playback control module 1104) can also perform control so that the program data recorded in the first storage area is loop-played in response to the playback instruction. Furthermore, the control module 110 (recording / playback control module 1104) can also operate loop recording and loop playback in parallel.

  For example, by loop playback control of the control module 110 (recording / playback control module 1104), the HDD 100 starts playing the program data from the first area (address 0001) of the first storage area, and the last area ( Continue to play program data up to address XXXX), play program data (program data updated by loop recording) from the top area again, and play program data (program data updated by loop recording) up to the last area to continue.

  That is, after the program data is reproduced from the first area to the last area of the first storage area, the program data updated by the loop recording is reproduced again from the first area to the last area of the first storage area. Such reproduction of program data is referred to as loop reproduction. That is, it is possible to continue to reproduce new program data in order from the old program data recorded in the first storage area by loop reproduction.

  When the HDD 200 is connected via the second USB terminal 126 during the loop recording described above or during loop recording and loop reproduction, the control module 110 (recording / reproduction area management module 1105) detects the connection of the HDD 200. (BLOCK 11 in FIG. 4), the HDD 200 is recognized, the second storage area (for example, the entire area) of the HDD 200 is formatted for loop recording / reproduction (BLOCK 12 in FIG. 4), and the HDD 200 connection processing is executed (FIG. 4). BLOCK 13). The second recording area is composed of a plurality of divided areas managed by a plurality of addresses.

  Further, the control module 110 (recording / reproduction area management module 1105) manages the first storage area of the HDD 100 and the second storage area of the HDD 200 as a logical continuous area, and this continuous area is a data processing area. It is managed as (recording / reproduction area). That is, the control module 110 (recording / reproduction area management module 1105) changes the data processing area from the first storage area to the continuous area. The control module 110 (recording / playback control module 1104) corresponds to the fact that the continuous area composed of the first storage area and the second storage area is managed as the data processing area, In order of the second storage area, control is performed so that data is recorded in the continuous area, and similarly, control is performed so that data is reproduced from the continuous area (BLOCK 14 in FIG. 4).

  For example, as shown in S12 or S13 of FIG. 3, the control module 110 (recording / playback control module 1104) controls to continue recording data in the first storage area (BLOCK141, YES), and the first Control is performed to record data in the first storage area (BLOCK 145) as shown in S13 of FIG. 3 until data recording on the final area of the storage area is completed (BLOCK 142, NO). Correspondingly, the HDD 100 continues to record data in the first storage area until the recording of data in the final area of the first storage area is completed.

  When the control module 110 (recording / playback control module 1104) completes the recording of data in the final area of the first storage area (BLOCK 142, YES), as shown in S14 of FIG. Control is performed to start data recording (BLOCK 143), and thereafter, control is performed to continuously record data in the second storage area (BLOCK 144), as indicated by S15 in FIG. In response to this, the HDD 100 starts recording data in the second storage area and continues recording data.

  In the state of S15 in FIG. 3, the continuous area is managed as the data processing area, but the control module 110 (recording / playback control module 1104) controls to record data in the second storage area. However, no control is performed to record data in the first storage area. In this state, the control module 110 (recording / playback control module 1104) can control to play back data from either the first storage area or the second storage area.

  Subsequently, the control module 110 (recording / playback area management module 1105) starts recording in the second storage area (that is, when data is started to be recorded in the second recording area). Change to 2 storage area. For example, the control module 110 (recording / reproducing area management module 1105) responds to the fact that the size of data recorded in the second storage area exceeds a predetermined size (that is, the data is sufficiently accumulated in the second recording area). The data processing area may be changed from the continuous area to the second storage area. That is, the control module 110 (recording / playback area management module 1105) changes the data processing area from the continuous area to the second storage area. As an example, the control module 110 (recording / playback area management module 1105) has recorded data up to the final area of the second storage area (the end of the second storage area) as shown in S16 of FIG. Correspondingly (that is, when data is sufficiently accumulated in the second recording area) (BLOCK15, YES), the data processing area is changed from the continuous area to the second storage area.

  In response to the second storage area being managed as a data processing area (loop recording / playback area), the control module 110 (recording / playback control module 1104), as shown in S17 and S18 of FIG. Control is performed so that data is loop-recorded in the storage area (BLOCK 16), and similarly, control is performed so that data is loop-reproduced from the second storage area.

In response to this, the HDD 100 loop-records data in the second storage area or loop-plays data recorded in the second recording area.

  Furthermore, the control module 110 (recording / playback area management module 1105) permits the disconnection of the HDD 100 in response to the data being recorded up to the last area of the second storage area (the end of the second storage area). (BLOCK 17). In response to this, the video processing module 113 outputs permission information for disconnecting the HDD 100, and the video display unit 141 displays permission information for disconnecting the HDD 100. For example, the video display unit 141 displays a guidance “HDD 100 is removable” (BLOCK 18).

  The control module 110 (recording / reproduction area management module 1105) corresponds to the HDD 100 setting completion (recognition of the HDD 100, formatting of the first storage area (for example, all areas) of the HDD 100, completion of connection processing of the HDD 100), The capacity of the first storage area of the HDD 100 can be output as a loop recording / reproducing capacity. In response to this, for example, the video display unit 141 displays the capacity of the first storage area as the loop recording / reproducing capacity.

  Further, in response to the control module 110 (recording / reproduction area management module 1105) managing a continuous area composed of the first storage area of the HDD 100 and the second storage area of the HDD 200 as a data processing area, The capacity of the second storage area of the HDD 200 can be output as a loop recording / reproducing capacity. In response to this, for example, the video display unit 141 displays the capacity of the second storage area as the loop recording / reproducing capacity. Thereby, even during the transition from the HDD 100 to the HDD 200, it is possible to display the loop recording / reproduction capacity (capacity of the second storage area of the HDD 200) after the completion of the transition.

  As described above, the digital television broadcast receiving apparatus (recording control apparatus) can perform loop recording on the HDD 100 without stopping the loop recording or requiring a special operation during loop recording of the program on the HDD 100. It is possible to switch to loop recording for the HDD 200.

  For example, when the digital television broadcast receiving apparatus (recording control apparatus) detects the HDD 200 during loop recording of a program on the HDD 100, the HDD 200 automatically formats the HDD 200 for loop recording and reproduction. Therefore, the HDD 200 can be used for loop recording and reproduction without any special operation by the user.

  Also, when the setting of the HDD 200 is completed during loop recording of a program to the HDD 100, the digital television broadcast receiving apparatus (recording control apparatus) divides the first recording area of the HDD 100 and the second recording area of the HDD 200 into a continuous area. And this continuous area is managed as a data processing area.

  Further, after the continuous area is managed as the data processing area, when sufficient data is accumulated in the second recording area of the HDD 200 (for example, when data is recorded to the end of the second recording area), the digital television The broadcast receiving apparatus (recording control apparatus) manages the second recording area as a data processing area, and loop-records the program in the second recording area. Thus, even during the transition from the HDD 100 to the HDD 200, sufficient program data recorded in the continuous area can be reproduced until sufficient data is accumulated in the second recording area of the HDD 200. That is, it is possible to prevent the reproducible program data from being reduced during the transition.

  Further, when the second recording area is managed as the data processing area, the digital television broadcast receiving apparatus (recording control apparatus) permits the disconnection of the HDD 100, for example, displays the disconnection permission information. Thereby, the user can physically remove the HDD 100.

  Further, in response to the digital television broadcast receiving apparatus (recording control apparatus) managing a continuous area composed of the first storage area of the HDD 100 and the second storage area of the HDD 200 as a data processing area, The capacity of the second storage area can be displayed as the loop recording / reproducing capacity. That is, the digital television broadcast receiving apparatus (recording control apparatus) displays the loop recording / reproducing capacity (capacity of the second storage area of the HDD 200) after the completion of the transition even during the transition from the HDD 100 to the HDD 200. Can do.

(Second Embodiment)

FIG. 6 is a state transition diagram illustrating an example of second recording / reproduction control according to the second embodiment, and FIG. 7 is a flowchart illustrating an example of second recording / reproduction control according to the second embodiment. is there. The basic flow of the second recording / reproducing control according to the second embodiment is the same as that of the first recording / reproducing control according to the first embodiment, and will be described with a focus on different parts.

  In the first recording / playback control according to the first embodiment, even if the setting of the HDD 200 is completed (states S12 and S13 shown in FIG. 3), data is recorded in the final area of the first storage area of the HDD 100. Until completion, data writing to the second recording area of the HDD 200 is not started (BLOCK 142, NO → BLOCK 145 shown in FIG. 5). That is, in the first recording / playback control, the setting of the HDD 200 is completed (the state of S12 and S13 shown in FIG. 3), and further, when the data recording to the final area of the first storage area of the HDD 100 is completed, Data writing to the second recording area is started (state of S14 shown in FIG. 3).

  On the other hand, in the second recording / reproducing control according to the second embodiment, when the setting of the HDD 200 is completed (the state of S22 shown in FIG. 6), data recording to the final area of the first storage area of the HDD 100 is performed. Even if the process is not completed, data writing to the second recording area of the HDD 200 is started (state of S23 shown in FIG. 6) (BLOCK 21, YES → BLOCK 22 shown in FIG. 7).

  That is, when the control module 110 (recording / playback area management module 1105) detects the connection of the HDD 200 during loop recording to the HDD 100 or during loop recording and loop playback, the control module 110 (recording / playback area management module 1105) The HDD 200 is recognized, the second storage area (for example, the entire area) of the HDD 200 is formatted for loop recording and reproduction, and the connection process of the HDD 200 is completed. Further, the control module 110 (recording / reproduction area management module 1105) manages the first storage area of the HDD 100 and the second storage area of the HDD 200 as a logical continuous area, and this continuous area is a data processing area. Manage as. That is, the control module 110 (recording / reproduction area management module 1105) changes the data processing area from the first storage area to the continuous area. The control module 110 (recording / reproduction control module 1104) performs data processing on the continuous area in response to the management of the continuous area composed of the first storage area and the second storage area as the data processing area. Is recorded, and similarly, data is controlled to be reproduced from the continuous area.

  In the second embodiment, the control module 110 (recording / playback control module 1104) does not proceed to the last area of the first recording area in response to the management of the continuous area as the data processing area. However, data recording to the first storage area is stopped and data recording to the second storage area is started (state of S23 shown in FIG. 6) (BLOCK21, YES → BLOCK22 shown in FIG. 7). Thereafter, the control module 110 (recording / reproduction control module 1104) continues to record data in the second storage area (states S24, S25, S27, and S28 shown in FIG. 6) (BLOCK21 and NO shown in FIG. 7). → BLOCK23).

  After starting recording in the second storage area, the control module 110 (recording / reproduction area management module 1105) changes the data processing area from the continuous area to the second storage area. For example, the control module 110 (recording / reproducing area management module 1105) responds to the fact that the size of data recorded in the second storage area exceeds a predetermined size (that is, the data is sufficiently accumulated in the second recording area). If so, the data processing area is changed from the continuous area to the second storage area. As an example, the control module 110 (recording / playback area management module 1105) has recorded data up to the final area of the second storage area (the end of the second storage area) as shown in S25 of FIG. Correspondingly (that is, when data is sufficiently accumulated in the second recording area), the data processing area is changed from the continuous area to the second storage area.
