The
international committee of the Moving Picture
Experts Group (MPEG) jointly with the International
Telecommunication Union (ITU) organization,
collectively, Joint Video Team (JVT) have defined a
standard for the next generation of video CODECs,
the H.264 standard.
The
recently added MPEG-4 part 10, also known as MPEG-4
AVC (Advanced Video Coding) or H.264, offers
significantly greater compression than its
predecessors. It can provide DVD-quality video at
under 40% of the bit rate of MPEG-2 and is
considered promising for full-motion video over
wireless, satellite, and ADSL Internet connections.
The MPEG-4 part 10 standard defines the decoding
algorithms and techniques and also provides
reference code for developers to utilize either in
their coding implementation or for bench-marking.
Because of its multi-disciplinary origins, experts
agree that H.264 will be the dominant video
compression standard for the next 8 to 10 years.
Many companies decided to use the
published reference code to support their
development efforts and improve upon that code but
have run into major road blocks. Many of these
companies have had to rethink their efforts and are
now going back to the drawing board or looking for
alternatives. The H .264 algorithms are so designed
that the encoding process contains more complexities
than the decoding process. While the standard
determines the decoding algorithm, the design of
encoding algorithms is open to individual
developers, allowing them to create value-added
programs. VidWare technology is a way for these
companies to recoup their time-to-market.
VidWare decided to entirely rewrite the code from
the ground up without incorporating any reference
code, nor making it platform-specific. The use of
VidWare proprietary technology improves well beyond
the performance of the H.264 reference code, while
respecting the standard.
