Problems solved by technology

[0008] However, in the above-mentioned conventional video recording and reproducing apparatus, there is a problem that it is necessary to supply power to all devices constituting the video recording and reproducing apparatus in conjunction with turning on the power of the display device. During the period of time when the device watches images from other sources, the image recording and reproducing device also consumes power in vain
That is, although responsiveness to user operations is good, there is a problem in terms of energy saving

Embodiment approach 1

[0026] figure 1 is a configuration diagram showing the configuration of an example of the video playback device according to Embodiment 1 of the present invention. A display device 113 capable of displaying images, such as a liquid crystal panel or a CRT monitor, is connected to the image reproduction device 100 . In addition, this video playback device 100 has a plurality of power supply modes referred to above as "normal mode", "standby mode", and "energy saving mode".

[0027] exist figure 1 In this case, the reproduction drive unit 102 reproduces video and audio information that is coded and recorded on the reproduction disk 101 , for example, an optical disk, that is, a video signal. The video signal to be played back is composed of stream information obtained by multiplexing coded video and playback control information of the stream information. The reproduction control information holds video and audio attribute information such as program list and / or stream control ...

Embodiment approach 2

[0094] In Embodiment 1 of the present invention, the case where the information recording medium is an optical disc is described as an example, and the video playback device in which the playback disc is an optical disc and reproduces video and audio information recorded on the optical disc by a playback drive unit is described. In Embodiment 2, a case in which the information recording medium is a hard disk is used as an example to describe a video recording and reproducing device having a recording and reproducing drive unit capable of recording video and audio information of a program obtained by receiving digital broadcasting on the hard disk. hard disk, and can reproduce video and audio information recorded in the hard disk.

[0095] Furthermore, in the video recording and reproducing device according to Embodiment 2, the information recording medium is not limited to a hard disk, and of course may be, for example, an optical disc capable of recording and reproducing video...

Embodiment approach 3

[0127] In the video playback device 100 of Embodiment 1 and the video recording / playback device 180 of Embodiment 2, when it is determined based on the operating status information of the connected display device 113 that the user is more likely to use the video playback device 100 or the video recording / playback device 180 When it is high, it makes it possible to shift the power supply mode from the standby mode to the power saving mode, but conversely, even when it is judged that the possibility of use by the user is low, it makes it possible to shift from the normal mode or the power saving mode to the standby mode without sacrificing too much. The more responsiveness, the better the energy saving.

[0128] Figure 9 It is a flowchart showing the workflow of the video playback device according to Embodiment 3 of the present invention. use Figure 9 The operation of shifting the power supply mode of the video playback device according to Embodiment 3 from the normal mode o...
