Description
Requests the current configuration of the video system. The returned
information includes: codec, resolution, bit rate, and mode.
Syntax:
SEND_COMMAND <DEV>,"'GET VIDEO'"
Variables:
codec = Off, MPEG2, or MPEG4.
resolution = D1, or SIF, or <width>X<height> (up to a D1 resolution).
bit rate = Returned in Kbps (kilobits per second).
mode = CBR (constant Bit rate) or VBR (variable Bit rate).
Example:
SEND_COMMAND ENCODER,"'GET VIDEO'"
System response:
VIDEO = MPEG2 D1 4000 CBR
Indicates that the video codec is configured to use an MPEG-2 stream, with a
D1 resolution at 4000 Kbps using a constant bit rate (CBR).
Requests the a description of the current video source type. This video type
indicates which rear connector is being used as the video input.
Syntax:
SEND_COMMAND <DEV>,"'GET VSOURCE'"
Variable:
source = SVID (S-Video) or COMP (Composite).
Example:
SEND_COMMAND ENCODER,"'GET VSOURCE'"
System response:
VSOURCE = COMP
Indicates that the MAX unit is being supplied with a Composite video type.
Starts the streaming of either the audio and/or video based on current
configuration. A stream can also be started via the browser-based UI pages.
Syntax:
SEND_COMMAND <DEV>,"'PLAY'"
Example:
SEND_COMMAND ENCODER,"'PLAY'"
Assigns the source for the audio signals being fed into the MAX unit and then
encoded.
Syntax:
SEND_COMMAND <DEV>,"'SET ASOURCE'"
Variable:
format = LINE (from the rear Stereo RCA connectors) or
MIC (from the rear Microphone port).
Example:
SEND_COMMAND ENCODER,"'SET ASOURCE MIC'"
Instructs the MAX-CSE to use the rear Microphone port as the audio source for
the encoded audio stream.
