RTP Buffering - Frame Based Buffering

Introduction

In Song module version 8 a new RTP buffering method called frame based buffering was introduced. The algorithm calculates the audio buffer level in milliseconds rather than in bytes.

Features

Frame based buffering allows:

• configurable decoding delay with one frame accuracy
• synchronisation of several decoders to the same stream (just by configuring them to the same initial delay)
• stable delay over long period of time
• automatic correction of clock difference between encoder and decoder
