Technical Field
The invention relates to the technical field of audio and video decoding, in particular to an audio and video coding and decoding transmission system.
Background
A video codec refers to a program or a device capable of compressing or decompressing digital video. Typically this compression is of lossy data compression. Historically, video signals have been stored in analog form on magnetic tape. With the advent and market introduction of Compact Disc, audio signals were stored digitally, video signals began to use the digitized format, and related technologies began to develop.
In daily life, video codecs are widely used. For example, in DVD (MPEG-2), in VCD (MPEG-1), in various satellite and terrestrial television broadcast systems, on the Internet. On-line video material is typically compressed using a wide variety of different codecs, and in order to be able to view the material correctly, the user needs to download and install a codec package-a compiled codec component ready for the PC. Compression of video by the user himself has become more popular with the advent of DVD recorders. Since DVDs sold in stores are generally large in capacity (dual-layer) and current dual-layer DVD recorders are not popular, users sometimes perform secondary compression on DVD material to enable complete storage on a single-sided DVD. With the rapid development of high technology, high definition video codecs are also in force to meet the needs of more fields. High definition video codecs may be applied to: video conference, security monitoring, medical teaching, classroom recording and broadcasting, unattended operation, court trial system and other software and hardware matching services under various environmental conditions.
