Please consult the manual of the refering decoder for this.
Here the steps for Winamp 5.05 (just works with MPEGL2 and MPEGL3)
· Ensure that the latest ‘in_rtp.dll’ Plugin is installed
· Step to menu item <File/Play URL..>
· Type in: rtp://<Multicast IP-address>:<port number>
Example:
rtp://225.0.0.2:5004
· Click the Open-button to establish connection

SAP Streaming
SAP streaming is more or less an enhancement of SDP streaming (see SDP streaming).
SDP and SAP streaming are supported with system software version 2.1.0.50 (or later).
SAP stands for session announcement protocol. Same as SDP streaming (see SDP
streaming) a SDP file is created but additionally the SDP information is send to the
Multicast address 224.2.127.254. The SAP decoder retrieves the SDP information from
this Multicast address (and not from the SDP Encoder). SAP announcements are sent on
port 9875.
There are two advantages of SAP streaming compared to SDP streaming:
a) Since the SDP file must not be retrieved from the encoder device, unidirectional
connections are sufficient (e.g. important for satellite transmissions).
b) At Multicast address 224.2.127.254 the SDP information of all SAP streaming encoders
is available (and not just the SDP information of one device).
More info about SAP can be found in rfc 2974 (www.ietf.org/rfc/rfc2974.txt).
1. Configuration steps at MERK II encoder
1.1 Codec settings
Configure the codec settings via menu item Settings/Codec:
· Interface: IP/RTP
· Encoder dependency: Remote
· Encoder algorithm: Algorithm supported by the other side codec
Note:
With SAP streaming the MERK II supports the algorithms AAC (MPEG4) and AAC (HE)
· Decoder dependency: Remote
1.2. Establish Connection
Click the CONNECT button to open the Connect-dialog:
· Select interface to IP
· Select SDP/Encoder
· Check SAP
· Type in the IP-address
· Click the OK-button to establish connection
