MAX-CSE Streaming Send_Commands (Cont.)
Command Description
GET VSOURCE
Get a description of the
source type used by the
current video stream. 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.
PLAY
Start the transmission of the
audio and/or video stream. 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'"
SET ASOURCE
Set the input source for the
encoded audio stream. 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.
SET AUDIO
Set the configuration
parameters for the audio
system. The configuration parameters include: codec, sampling rate, and bit rate.
Note: Setting the audio configuration during the 'play' state has undefined
results.
Syntax:
SEND_COMMAND <DEV>,"'SET AUDIO <codec> <sampling>
<rate>'"
Variables:
codec = Off, MP2, or MP3.
sampling rate = 32 KHz, 44.1 KHz, and 48 KHz. Sampling rate given in
KHz (KiloHertz).
Note: A sampling rate of 44.1 KHz MUST be entered as 44, using
44.1 will not work properly.
bit rate = 96 Kbps and 192 Kbps. Effective bit rate in Kbps (kilobits per
second).
Example:
SEND_COMMAND ENCODER,"'SET AUDIO MP2 48 10'"
Sets the audio configuration to use an MP2 audio codec sampling at 48KHz,
while transmitting at 10 Kbps.
