Video displaying system and reproducing apparatus
A technology for an image display system and a display device, which is applied to stereo systems, components of a TV system, and image communication, etc., can solve the problems of inability to output, without considering audio-visual correlation, and the inability of the image signal reproduction device to determine the 3D display mode of the display device. , to achieve the effect of convenient use and promotion of audio-visual

Embodiment 1
[0031] figure 1 It is a block diagram showing the video transmission system of this embodiment, and the video signal playback device 11 is connected to the 3D display device 21 through the HDMI cable 31 . The video signal reproducing device 11 is, for example, a DVD player, a DVD recorder, a Blu-ray Disc (Blu-ray Disc) player, a Blu-ray Disc (Blu-ray Disc) recorder, an HDD recorder, etc., and the video signal reproducing device 11 has an optical disc or Storage medium 111 such as a magnetic recording disk or semiconductor memory, data reading unit 112, decoding unit 113, OSD (OnScreen Display: On Screen Display) generating unit 114, video signal combining unit 115, control unit 117, EDID (Extended Display Identification Data: Extended display identification data) readout unit 118, and video transmission unit 119. In addition, the storage medium 111 may be built in the video signal playback device 11 , or may be detachable from the video signal playback device 11 .

Embodiment 2
[0066] Figure 5 This is another definition example of the 3D viewing requirement flag 3D "Condition_to_see_3D". figure 1 block diagram and figure 2 The composition table of the information is the same as that of Example 1.
[0067] exist Figure 5 in, with image 3 Similarly, "00" indicates that there is no information related to audio-visual requirements in consideration of backward compatibility. "01" indicates that 3D glasses are not required, but the display mode of the 3D display device 21 needs to be manually switched from 2D to 3D. "10" indicates that, for example, in the case of the parallax barrier method, 3D glasses or a change of the display mode are not required for 3D viewing. "11" means 3D glasses are required.
[0068] Image 6 is the action flow chart, with Figure 4 The difference is the conditional branch of step 514 and the OSD display content of step 517. Otherwise, the same reference numerals are attached.

Embodiment 3
[0072] Figure 7 Another example of the form of information related to the 3D video signal reception capability of the 3D display device 21, the 3D display method, and the like is shown. and figure 2 The difference is that one byte is reserved for the 3D viewing requirement flag "3D_Display" at the q+1th byte, and the flag "3D_Display_present" indicating the presence of the 3D viewing requirement flag "3D_Display" is set in bit 2 of the pth byte. The status of bit 1 and bit 0 of the Pth byte is "Reserved" (reserved) remains unchanged, and can be used in future expansion.
[0073] Figure 8 An example of the definition of the flag "3D_Display" indicating the 3D viewing requirements and "3D_Display_present" indicating its presence. In the display device described in Non-Patent Document 1, "3D_Display_present" is "0" and since the 3D viewing requirement flag "3D_Display" does not exist, the feature of backward compatibility can be maintained.
