I8	HDMI 1.3

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 also studied. This course has been delivered to several companies developing mobile phone chipsets. A more detailed course description is available on request at info@ac6-formation.com

Prerequisites
	Experience of a digital bus is recommended.
