Abstract :
The Grand Alliance (GA) was formed to define and construct a system for the delivery of HDTV using terrestrial broadcast channels. This system is composed of the best components from previously competing systems considered by the FCC. MPEG-2 syntax is used with novel encoding techniques to deliver a set of video scanning formats for a variety of applications. The paper focuses on video compression technology and also describes the important features and concepts embodied in the GA system as compared to the previous digital HDTV systems
