Аннотация

With the advent of the MPEG-4 Visual and H.264 compression standards, the role of the MPEG-2
compression standard has not diminished at the present time, since these standards are largely compatible, especially
for information highways. Today, in a number of countries, the MPEG-2 compression standard is actually the main
one for broadcasting, the functioning of which is based on the operation of DVB-T terrestrial digital television
systems.
Due to the fact that the majority of the currently used STBs support the MPEG-2 standard, it will remain
widespread for at least the next few years.
The ITU-T H.264 /MPEG-4 Part 10 AVC standard (abbreviated as H.264/AVC) is a promising new technology
for encoding and compressing audiovisual information. The compression efficiency of the H.264/AVC standard is
higher than the MPEG-2 standard with equal visual perception. The H.264/AVC standard was developed independent
of the transport layer of the transmission systems used. Therefore, information delivery in the H.264/AVC standard
can be carried out using any existing transmission and broadcasting systems, including: systems with IP protocols
(including streaming delivery), transport streams of broadcasting systems in the MPEG-2 standard, as well as
specific formats H.264 / AVC files for storage and processing on servers.
