FIG. 4 is a table (FIGS. 4A to 4C) showing various states corresponding to the operation principle of the embodiment of the broadcast recording / reproducing system of the present invention.

  As shown in FIG. 3, for example, in a recording / playback apparatus (recorder) 20 such as a Blu-ray recorder, it is determined whether or not the playback state in which the recorded content previously recorded by the user has been played back has ended. (Step S110). Specifically, as shown in FIG. 4A, this playback state means a state in which the recording / playback apparatus 20 plays back the recorded content and the user is viewing. More specifically, the display device (TV) 10 selects the terminal S1 in FIG. 1, and the recording / playback device (recorder) plays back the recorded content.

  As a result of the determination in step S110, if it is determined in the recording / playback apparatus 20 that the playback state for playing back the recorded content has ended (step S110: Yes), the recording / playback apparatus 20 further changes to the first state. It is determined whether or not the length of time is greater than a predetermined time (step S120). Here, in the first state according to the present embodiment, the display device 10 displays one broadcast content via the recording / reproducing device 20 and one broadcasting channel set in the recording / reproducing device 20. It means the state that is. Specifically, as shown in FIG. 4B, in the first state, the broadcast content (so-called live broadcast or live broadcast program) that the user broadcasts in real time via the recording / reproducing apparatus 20 is used. Means the state of watching. More specifically, the display device (TV) 10 selects the terminal S1 in FIG. 1, and the recording / reproducing device (recorder) receives a broadcast channel such as “n channel”, for example. . On the other hand, as a result of the determination in step S110, if the recording / reproducing apparatus 20 does not determine that the reproduction state for reproducing the recorded content has ended (step S110: No), the process returns to step S110.

  As a result of the determination in step S120, if it is determined that the length of time in the first state is greater than the predetermined time (step S120: Yes), for example, the recording / reproducing apparatus via communication means compliant with the IEEE 1394 standard Channel information related to the broadcast channel received by the (recorder) 20 is output from the recording / playback device (recorder) to the display device (TV) 10 (step S130). On the other hand, as a result of the determination in step S120, when it is not determined that the length of time in the first state is greater than the predetermined time (step S120: No), the process returns to step S120.

  Next, the display device (TV) 10 receives the same broadcast channel “n channel” as the broadcast channel received by the recording / playback device (recorder) 20 based on the input channel information. Tuning is performed (step S140).

  Next, the recording / reproducing apparatus (recorder) 20 turns off the power of the recording / reproducing apparatus (recorder) 20 (step S150). Therefore, in the broadcast recording / playback system, it is possible to realize the second state in which the user is viewing a live broadcast via the display device (TV) 10. Specifically, in the second state, as shown in FIG. 4C, the display device (TV) 10 receives the same broadcast channel “n channel” as the recording / reproducing device (recorder) 20. In addition, after tuning, the recording / reproducing apparatus (recorder) 20 is in a state in which the power of the recording / reproducing apparatus (recorder) 20 is turned off.

(2) Examination of actions and effects according to this embodiment
Next, the operation and effect of the embodiment according to the broadcast recording / playback system of the present invention will be examined with reference to FIG.

  In general, as shown in the playback state of the table in FIG. 4A described above, for example, video content recorded in a recording / playback apparatus such as a DVD recorder or a Blu-ray recorder and output from the recording / playback apparatus When the user views the content via a display device such as a TV, for example, video content is reproduced.

  Next, as shown in the first state of the table of FIG. 4B, the general recording / reproducing apparatus automatically connects to the recording / reproducing apparatus when the reproduction of the video content is completed. The broadcast content is switched to a reception state via tuning means such as an antenna and a tuner.

  In this case, the user often continues to watch broadcast content (so-called live broadcast or live broadcast program) broadcast in real time via a tuning means such as a tuner connected to the recording / reproducing apparatus. Here, when the user views a live broadcast, as shown in the second state of the table of FIG. 4C, in order to realize power saving and energy saving in the broadcast recording / playback system. It is preferable to turn off the power of the recording / reproducing apparatus and watch the live broadcast via tuning means such as a tuner connected to the display device.

  Temporarily, in order to realize power saving and energy saving in the broadcast recording / playback system by the user's operation, the following complicated operation is required, which reduces the convenience for the user.

As the second step, the user (i) another broadcast channel set in the tuning means such as a tuner connected to the display device, (ii) connected to the recording / playback device, such as a tuner, etc. The operation for switching to one broadcast channel set in the tuning means is required. Alternatively, when the above-described user operation is not performed, the user continues to view the live broadcast via a tuning unit such as a tuner connected to the recording / reproducing apparatus as it is. It becomes technically difficult to realize power saving and energy saving.

  More specifically, in a general recording / reproducing apparatus, even if there is no recording operation or reproducing operation and the reception state of the broadcast channel continues, there is a possibility that the user is watching the broadcast channel. In order to avoid the user's viewing being interrupted by being turned off, a long time is set as a threshold for automatically turning off the power. For this reason, even if the user forgets to turn off the power, the power is often kept on. In order to save power and energy, it is desirable to set the threshold time for automatically turning off the power to be short, but it is necessary to devise so that the user's viewing is not interrupted. Further, in a general recording / reproducing apparatus, the user does not notice the difference between viewing a live broadcast by a tuner of the recording / reproducing apparatus and viewing a live broadcast by a tuner of a display apparatus such as a TV. Is difficult. Therefore, when it is difficult for even a user who is trying to save energy, it is difficult to notice a technical problem that it is not possible to perform an operation for switching to live broadcast viewing using a display device such as a TV.

  On the other hand, in this embodiment, in a display device such as a TV, for example, another channel preset in the display device is set as one broadcast channel set in a recording / playback device such as a Blu-ray recorder. It is possible to switch automatically. Or, in a similar manner, in a recording / reproducing apparatus such as a Blu-ray recorder, one channel set in the recording / reproducing apparatus is automatically changed to another broadcast channel set in a display apparatus such as a TV. It is possible to switch. In other words, it is possible for the display device and the recording / reproducing device to have the same broadcast channel based on or not based on the user's desire.

  Therefore, under the control of the control means, from the first state where (i) the display device displays one broadcast content via one broadcast channel via the recording / reproducing device, (ii) the display device However, it is possible to switch to the second state in which the one broadcast content is displayed via one broadcast channel without going through the recording / reproducing apparatus.

  As a result, it is possible to automatically turn off the power of the recording / reproducing apparatus that is functioning redundantly while viewing one broadcast channel desired by the user. The effect of power and energy saving can be significantly improved. In addition, it is not necessary for the user to perform almost or completely the operation for remarkably improving the power saving and energy saving effects in the broadcast recording / playback system, so the convenience in the user operation can be improved. It is.
