formateur
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
