Alternatively, the discrimination information is: (ii) the display device 10 receives the recording / playback device 2 A flag indicating whether or not it is possible to switch to the second state described later, which displays one broadcast content via one broadcast channel without using 0 or 30, may be included. Specifically, instead of based on this discrimination information, the display device 10 shares (acquires) channel information related to one broadcast channel set by the recording / playback device 20 or 30 by the user's own button operation or remote control operation. It may be possible to set in advance so as not to. Alternatively, the display device 10 displays one broadcast content via one broadcast channel via the recording / reproducing device 20 or 30 by the user's own button operation or remote control operation, which will be described later. You may do so without switching to the second state.

[0088] In particular, the control means for overall control of the entire broadcast recording / reproducing system 1 according to the present embodiment is the control information input / output between the display device 10 and the recording / reproducing device 20 or 30 described above. It may be. Alternatively, it may be a control unit such as a CPU (Central Processing Unit) provided in the display device 10. Alternatively, it may be a control unit such as a CPU provided in the recording / reproducing apparatus 20 or 30. In addition, when there are a plurality of control means, the power of one control unit such as a CPU provided in the display device 10 is compared with another control unit such as a CPU provided in the recording / reproducing device 20 or 30. For example, by outputting a standby command for turning off the power, the broadcast recording / reproducing system according to this embodiment is controlled based on the cooperative control of a plurality of control means.

Note that the plurality of recording / reproducing devices and the display device only need to satisfy the condition that various kinds of information can be communicated (exchanged) with each other, and therefore other types of communication means may be used. The plurality of recording / reproducing devices and the display device each have a built-in television tuner, and are connected to receiving means such as an antenna. Therefore, the broadcast content output from the receiving means is input to the plurality of recording / reproducing devices and the display device, and the plurality of recording / reproducing devices and the display device can be tuned respectively. . Note that the receiving means such as the antenna described above and the TV tuner constitute an example of the tuning means according to the present invention.

[0090] (1 2) Principle of operation

Next, with reference to FIG. 3 and FIG. 4, the operation of the embodiment according to the broadcast recording / playback system of the present invention will be described. Advance the explanation of the principle of operation. FIG. 3 is a flowchart showing the operation principle of the embodiment according to the broadcast recording / reproducing system of the present invention. FIG. 4 is a table (FIGS. 4 (a) to 4 (c)) showing various states corresponding to the operating principle of the embodiment of the broadcast recording / reproducing system of the present invention.

[0091] As shown in FIG. 3, for example, the recording / playback device (recorder) 20 such as a Blu-ray recorder is turned to V to finish the playback state in which the user recorded previously and plays back the recorded content. It is determined whether or not the force is applied (step S110). Specifically, as shown in FIG. 4 (a), this playback state means a state in which the recording / playback apparatus 20 plays back the recorded content and the user is viewing it. More specifically, the display device (TV) 10 selects the terminal S1 in FIG. 1 and plays back the recorded content by using the recording / playback device (recorder).

As a result of the determination in step S110, when it is determined that the recording / playback apparatus 20 has finished playing the recorded content (step S110: Yes), the recording / playback apparatus 20 further It is determined whether or not the length of time in the first state is greater than a predetermined time (step S120). Here, the first state according to the present embodiment means that the display device 10 is set to the recording / reproducing device 20 via the recording / reproducing device 20 and transmits one broadcast content via the one broadcasting channel. Means the displayed state. Specifically, as shown in FIG. 4 (b), the first state is that the user broadcast content (so-called live broadcast or live broadcast) broadcast in real time via the recording / playback device 20. It means the state of watching a program. 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. Yes. On the other hand, as a result of the determination in step S110, if it is not determined that the recording / playback apparatus 20 has finished the playback state for playing back the recorded content (No in step S110), the process returns to step SI10.

[0093] 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, a communication means compliant with the IEEE1394 standard is used. Channel information on the broadcast channel received by the recording / reproducing device (recorder) 20 is output from the recording / reproducing device (recorder) to the display device (TV) 10 (step S130). . On the other hand, as a result of the determination in step S120, the length of time in the first state is predetermined. If it is not determined that the time is greater than 時間 (step S120: No), the process returns to step S120.

Next, the display device (TV) 10 receives the same broadcast channel as the broadcast channel received / recorded by the recording / playback device (recorder) 20 based on the input channel information! Tuning is performed to receive “n channels” (step S 140).

Next, the recording / reproducing device (recorder) 20 turns off the power of the recording / reproducing device (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 the live broadcast via the display device (TV) 10. Specifically, in the second state, as shown in FIG. 4 (c), the display device (TV) 10 receives the same broadcast channel “n channel” as the recording / reproducing device (recorder) 20. In addition, after performing the tuning, the recording / reproducing apparatus (recorder) 20 is in a state where the recording / reproducing apparatus (recorder) 20 is turned off.

[0096] (2) Examination of actions and effects according to this example

Next, referring to FIG. 4 described above, the operation and effect of the embodiment according to the broadcast recording / playback system of the present invention will be examined.

[0097] Generally, as shown in the playback state of the table in Fig. 4 (a), a video is 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 video content via a display device such as a TV, the video content is reproduced.

[0098] Next, as shown in the first state of the table in Fig. 4 (b), a general recording / playback device is automatically connected to the recording / playback device when the playback of video content is completed. For example, it switches to the broadcast content reception state via tuning means such as an antenna and tuner.

[0099] In this case, the user views the broadcast content broadcast in real time (so-called live broadcast or live broadcast program) via a tuning device such as a tuner connected to the recording / playback apparatus. Often continues. Here, when a user views a live broadcast, as shown in the second state of the table in FIG. 4 (c), in order to realize power saving and energy saving in the broadcast recording / playback system, Turn off the recording / playback device and display It is preferable to view live broadcasts via tuning means connected to the device, such as a tuner.

[0100] To realize power saving and energy saving in the broadcast recording / playback system by user operations, the following complicated operations are required, which reduces user convenience. End up. That is, as the first step, the user needs to turn off the power of the recording / reproducing apparatus. As a second step, the user (i) connects another broadcast channel set in a tuning means such as a tuner connected to the display device, for example (ii) connected to the recording / playback device, for example a tuner. An operation to switch to one broadcast channel set in the first 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 will be technically difficult to realize power saving and energy saving.

[0101] In more detail, in a general recording / playback apparatus, even if the reception state of a broadcast channel without a recording or playback operation continues, the user may be watching the broadcast channel. In order to avoid the interruption of the user's viewing by turning off the power automatically, a long threshold time is set 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. To save power and energy, we want to set the threshold time for turning off the power automatically, but we need to devise it so that user viewing is not interrupted. In general recording / playback apparatuses, the user does not notice the difference between viewing a live broadcast by a tuner of the recording / playback apparatus and watching a live broadcast by a tuner of a display device such as a TV. Is difficult. For this reason, when it is difficult for even a user who is trying to save energy, it is impossible to perform an operation for switching to viewing a live broadcast on a display device such as a TV.

In contrast, in the present embodiment, in a display device such as a TV, for example, another channel preset in the display device is used as a recording / playback device such as a Blu-ray recorder. It is possible to automatically switch to one broadcast channel set in the position. Alternatively, 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, in the display device and the recording / reproducing device, it is possible to make the broadcast channel the same based on or not based on the user's desire.

Therefore, under the control of the control means, (0 display device displays one broadcast content via one recording channel via the recording / reproducing device, and from the first state, ( ii) The display device can be switched to the second state in which the one broadcast content is displayed via one broadcast channel without going through the recording / reproducing device.

[0104] As a result, it is possible to automatically turn off the power of the recording / playback apparatus functioning redundantly while viewing one desired broadcast channel, and broadcast recording / playback is possible. It is possible to significantly improve the power saving and energy saving effects in the system. In addition, the user does not have to perform almost or completely the operation for significantly improving the power saving and energy saving effects in the broadcast recording / playback system, so that the convenience in the user operation is improved. It is possible.
