Unicast RTP

Top  Previous  Next

Unicast RTP connections can be established by CENTAURI’s of type 300x, 330x, 400x, MERKII and GANYMED’s 1102 using system software version 2.0.0.132 (or later).

 

RTP (=Realtime Transport Protocol) protocol bases on UDP (= User Datagram Protocol). Therefore the RTP implementation of codec_name_arial12_001 is an enhancement of the UDP implementation. In opposite to the pure UDP implementation RTP guarantees the right sequence of packets at the receiver side.
RTP supports the following features:
- payload-type identification
- sequence numbering
- time stamping
- source identification
RTP is implemented according to rfc 3550 (www.ietf.org/rfc/rfc3550.txt).

 

If possible RTP is the recommended IP-transmission method between codec_name_arial12_002.

 

1. Unidirectional RTP connections

Unidirectional IP connections between two codec_name_arial12_002 can established by the following steps:

1.1 Codec Settings

Configure the codec settings via menu item Settings/Codec (valid for both codec_name_arial12_002):

Interface: IP
Encoder dependency: Remote
Decoder dependency: Remote

The establishing codec_name_arial12_001 determines the algorithm, the sample rate, the bit rate and the mode of the transmission.

1.2 Establish Connection

Click the CONNECT button to open the Connect-dialog:

Select interface to IP
Select RTP
Type in the IP-address of the other codec in the address field
Click the OK-button to establish connection

 

2. Bidirectional RTP connections

There are two ways to establish a bidirectional RTP connection:

Establish a unidirectional RTP connection on both codec_name_arial12_002
Use a special codec configuration on the establishing codec_name_arial12_001

2.1 Special configuration on establishing MAYAH codec

Configure the codec settings via menu item Settings/Codec:

Encoder dependency: remote
Decoder dependency: local

2.2 Special configuration on non-establishing MAYAH codec

Configure the codec settings via menu item Settings/Codec:

Encoder dependency: remote
Decoder dependency: remote

Note:

At such bidirectional RTP connections different settings for sending and receiving can be used. The encoder settings determine which quality is sent whereas the decoder settings determine which quality is received.

Note 2:

In opposite to bidirectional UDP connections bidirectional RTP connections can be disconnected by one side (i.e. the establishing side) provided they were established by one side.

Lit up Connect LED:
RTP sending codec_name_arial12_001
Lit up Framed LED:
RTP receiving codec_name_arial12_001
