LSI DVDR-X30 Features List

DivX/ MPEG4 Feature List DivX Playback on the DVDR-X30 Product Over view MPEG-4 The ISO/IEC 14496/ MPEG-4 is an international video standard characterized by superior flexibility and scaling. Its usefulness spans from low to intermediate bit rates, delivering a competitive advantage over other standards. MPEG-4 offers a variety of profiles, useful for specific applications. The most commonly used profiles are Simple Profile (SP) and Advanced Simple Profile (ASP). Due to its similarity with the MPEG-2 standard, support for MPEG-4 is feasible without adding extra cost to the existing silicon and system infrastructures. DivX3.11 DivX3.11 is a format that has come from an early submission of the MPEG-4 standard to the ISO/ITU committee. Because DivX3.11 was created before the ratification of the MPEG-4 standard, it is not MPEG-4 compliant. It is primarily based on MPEG-4 simple profile with significant differences in coding tables. DivX4.x, DivX5.x, DivXPro In early 2000, DivX Networks created an open-source MPEG-4 CODEC known as DivX4.0 enabling content distribution on the Internet. DivXNetworks later decided to close the source code distribution, and released DivX5.0 which was an improved CODEC compared to DivX4.0. Both DivX4.0 and DivX5.0 are based on MPEG-4 Simple Profile and the CODEC can be downloaded without a charge. Next the company released DivXPro, which is based on the MPEG-4 Advanced Simple Profile (ASP). DivXNetworks later removed the requirements for the support of quarter-pixel (Qpel) and global motion compensation (GMC) which is now termed ASP*. Xvid XviD (DivX spelled backwords) is an open-source alternative to DivX that is a fully compliant MPEG-4 CODEC based on Simple Profile and Advanced Simple Profile tools, and is designed for cross-platform compatibility. XviD is not officially sponsored by any corporations, and is a continuously-evolving implementation of the MPEG-4 CODEC.
