This guide introduces MPEG fundamentals, video and audio compression, standards, streams, transport, and testing methods.
The document provides an overview of MPEG, describing it as a family of audio/video compression standards rather than a single format. It explains the role of MPEG in digital video and audio, the need for compression, and the basic principles behind entropy coding and perceptual considerations.
It then covers detailed topics such as video and audio compression techniques, MPEG layers, elementary and packetized elementary streams, program and transport streams, digital modulation schemes, DVB/ATSC standards, data broadcasting, and testing procedures for MPEG implementations. This manual is written in Chinese.
MPEG is the abbreviation for the Moving Picture Experts Group.
Practical compression systems typically combine two techniques: improving coding efficiency and removing redundant information.
Compression reduces the data rate of digital audio/video, allowing lower storage and transmission bandwidth.
