Note for Decoder

In Decoder Devices, the format of the Video Out was decided by the video source received from the encoder. For example, the Video Out format is NTSC when the decoder received the NTSC video stream from the encoder. However, the VIDEO_TV configuration in the decoder is used for the initializing the display of Video Out (including the OSD position, blue screen if there is no video).

Special design in TV Standard auto detectable video servers

To have correct display on TV by a decoder when video loss occurs in a video server, the video server has to save the TV Std. setting to its configurations in flash when the video state is recovered from video loss to video lock. The video server could use this video TV setting to setup the TV decoder when it was rebooted again.

If the CHANNEL=n was not set with this URL to the Multi-Channel device, this command is read-only command and the CHANNLE 1 video server's VIDEO_TV configurations will be returned. If the CHANNEL 1 video server does not connect to the router, the error message will be returned.
