IM1 HDMI 1.4a

This course covers the HDMI multimedia interface

Objectives

The course describes the architecture of a HDMI source-cable-sink system.
An introduction to Video and Audio standards is done prior to clarifying how this standards are transported through HDMI.
The analog interface is studied in detail, particularly the TMDS specification.
The course clarifies information coding / decoding schemes.
Content protection mechanisms are explained.
Ethernet connectivity and audio return channel are also covered.
This course has been delivered to several companies developing mobile phone chipsets.

A more detailed course description is available on request at training@ac6-training.com
