Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a control method for a video playback device or a recording / playback device having no display function, such as a cathode ray tube.
[0002]
[Prior art]
A conventional recording / playback apparatus (for example, see Patent Document 1) will be briefly described.
[0003]
In FIG. 9, the STB 111, DVHS 112 and DTV (digital TV) 113 are connected by cables 114 and 115 of a digital interface standard such as IEEE1394. That is, the terminal D1 of the STB 111 and the terminal D2 of the DTV 113 are connected by the cable 114, and the terminal D3 of the DTV 113 and the terminal D4 of the DVHS 112 are connected by the cable 115.
[0004]
The STB 111, DVHS 112 and DTV 113 are also connected by an analog cable. That is, the analog output terminal Ao1 of the STB 111 is connected to the analog input terminal Ai1 of the DTV 113, and the analog output terminals Ao2 and Ao3 of the DVHS are connected to the analog input terminals Ai2 and Ai3 of the DTV 13, respectively.
[0005]
The STB 111 as a source device includes a demodulation circuit 121, a TSP processing circuit 122 for processing a transport stream, a decoder 123, and a 1394 processing circuit 124. The DTV 113 includes a 1394 processing circuit 131, a decoder 132, a selector 133, a monitor 134, and an input control switching circuit 135. The DVHS 112 includes a selector 125, a controller 130, a 1394 processing circuit 129, an encoder / decoder 126, a recording / reproducing processing circuit 127, and a recording medium 128.
[0006]
By the 1394 processing circuit 129, data can be transmitted and received via the cable 115 connected to the terminal D4, and an analog video / audio signal can be captured via the analog input terminal Ai4.
[0007]
Here, it is assumed that the user instructs confirmation of the recorded program. Then, the controller 130 first checks the display device connected to the network, and detects whether or not the display device has a decoder.
[0008]
For example, the controller 130 can confirm the presence / absence of the decoder of the display device by a method in which the presence / absence of the MPEG2 decoder is described at a predetermined address of a configuration ROM (Configuration ROM) defined by the IEEE 1394 standard. . That is, in this method, the controller 130 of the DVHS 112 reads the information in the configuration ROM space of the DTV 113 via the 1394 processing circuits 129 and 131, and detects that the MPEG2 decoder 132 is present.
[0009]
Thus, the controller 130 detects that the DTV 113 includes the MPEG2 decoder 132. In this case, the DTV 113 can receive and decode the MPEG2-TS via IEEE1394. The controller 130 controls the STB 111 via the 1394 processing circuits 129 and 124 to output the MPEG2-TS from the TSP processing circuit 122 to the DTV 113 via the terminal D1, the cable 141 and the terminal D2 from the 1394 processing circuit 124. .
[0010]
The input control switching circuit 135 receives an instruction from the controller 130 from the 1394 processing circuit 131, and causes the selector 133 to select the decoder 132. Note that the input control switching circuit 135 may cause the selector 133 to select the decoder 132 based on a user operation.
