CHxx_VIDEO_CONNECT

Description

> Get or Set the method of video/audio streaming to connect to the encoder.

> There are three methods of video/audio streaming supported now. They are Multicast, UniCast and RTP.

> In Unicast Method, it uses the TCP to connect the encoder through the proprietary protocol.

> In Multicast Method, it uses the UDP to get the video/audio streams multicasting by an encoder.

> In RTP Method, the decoder setup the video/audio streams through RTSP. Base on the RTSP signaling, the video/audio streams will be carried by unicast or multicast UDP session.

> In WPL Decoder Devices, it could record up to 16 encoder configurations. The decoder could connect to these encoders one by one. Only one encoder will be connected at any time. The xx in this URL is in the range of 01 and 16.

> In EPL Decoder Devices, there is only one encoder configurations will be recorded. The decoder will connect to this encoder only. The xx is fixed to 01 then.

> The mapping of the input argument and the method of video/audio streaming is listed below.

> Input Argument | Method of Streaming
> 0 | Multicast
> 1 | Unicast
> 2 | RTP

> 0, 1 or 2
