What is A3 and MPEG4?
• What is A3
• A3 stands for Advanced Modulation, Advanced Coding and
Advanced Compression. It is a new technology that will
allow DIRECTV to offer more high-definition (and ultimately
standard) channels.
• What is MPEG4
• MPEG4 is the most recent version of a standard for the
digital representation of video, audio and certain types of 3D
information. It processes detailed 3D representation for
faces, human bodies and general 3D scenes. The 3D scene
representation points to the VRML (Virtual Reality Modeling
Language) standard as it's representation.
