Overview

Introduction

RTP, the real-time transport protocol, provides end-to-end network transport functions suitable for applications transmitting real-time data, such as audio, video or simulation data, over multicast or unicast network services. RTP does not address resource reservation and does not guarantee quality-of- service for real-time services.

Important! The DSP-2 card supports up to 15 RTP sessions.

TLVs Used

The following TLV is used to enable RTP:

0x0687 - Enable RTP for Play/Record File
