Session-Oriented Vod - Motorola APEX1000 Installation And Operation Manual

Session-Oriented VOD

There are three leading session VOD architectures, RTSP, MHA, and RPC.
•
Legacy VOD architectures are based on UDP port mapping algorithms, which are
static from the view of the Edge QAMs.
•
Emerging VOD architectures are session oriented, whereby each VOD session is
signaled through the whole network.
RTSP/MHA Architecture
RTSP (Real Time Streaming Protocol) and MHA are on-demand network control systems.
MHA and RTSP are similar and utilize the same protocols for communication and control.
The figure below illustrates this architecture:
