I19	Display Port 1.1a

This course covers the Display Port multimedia interface

Objectives The course describes the architecture of a DisplayPort source-cable-sink system. An introduction to Video and Audio standards is done prior to clarifying how this standards are transported through DisplayPort. The analog interface is studied in detail. The course clarifies information 8b10b coding / decoding schemes. Content protection mechanisms are also studied. A more detailed course description is available on request at info@ac6-training.com

Prerequisites
	A basic knowledge of multimedia standards (audio & video).
