MAX-CSE/MAX-CSD10 Operation/Reference Guide
MAX-CSD Streaming Send_Commands (Cont.)
Command Description
SET SAP IP ALT
Set the SAP Listener IP Alter-
native multicast address.
Syntax:
SEND_COMMAND <DEV>, 'SET SAP IP ALT <Addr>:<Port>'
Variable:
Addr = multicast IP address
Port = port number
Example:
SEND_COMMAND DECODER, 'SET SAP IP ALT 224.3.127.254:1234'
SET SESSION CURSOR
Selects the session for
streaming later.
This command allows the user to select the session for later streaming when
the user sends the play command.
Syntax:
SEND_COMMAND <DEV>, 'SET SESSION CURSOR <num>'
Variable:
Num = 1 to "SESSION LIST="
Example:
SEND_COMMAND DECODER, 'SET SESSON CURSOR 1'
SET URL
Set the URL description of
the audio/video stream.
The 'UDP' protocol represents MPEG-2 Transport Stream layered directly onto
UDP. This protocol is only available for MPEG-2. Audio is multiplexed with the
video, so no audio port is needed.
The 'RTP' protocol represents MPEG-2/4 Elementary Streams encoded as
MPV (33) data as defined by RFC 3550 and 3551. If no audio port is given, it is
assumed to be the video port plus 2.
Syntax:
SEND_COMMAND <DEV>,'SET URL <Protocol> <Addr> <Port>
[<Audio Port>]'
Variables:
Protocol = RTP or UDP
Address = Address of stream in IPv4 dot notation
Port = Primary port for audio/video transport.
Audio Port = Port for audio stream (RTP only)
Example:
SEND_COMMAND DECODER,'SET URL UDP 224.0.0.1 5000'
Sets the URL for a multicast session at 24.0.0.1 and port 5000. Since the
protocol is UDP, a second audio port is not needed.
SET VIDEO
Set the configuration
parameters for the video
codec.
Sets the current configuration of the video system. Configuration includes
codec and resolution. Setting the video configuration during 'play' state has
undefined results.
Syntax:
SEND_COMMAND <DEV>,'SET VIDEO <Codec>'
Variable:
Codec = OFF or MPEG2 or MPEG4
Example:
SEND_COMMAND DECODER,'SET VIDEO MPEG2 '
