With digital TV rolling out across the world using the MPEG-4 AVC standard, you might think that the work has all been done. But the MPEG standards group has launched five new profiles for professional video equipment.
These have been developed jointly with the International Telecommunications Union's (ITU-T) Study Group 16, (as AVC is also the ITU's H.264 standard) and with the Society for Motion Picture and Television Engineers (SMPTE).
These profiles will serve applications in the professional domain with enhanced compression capabilities for colour sampling using the full range 4:4:4 (used by Blu Ray and HD DVD systems)and bit depth dynamic ranges up to 14 bits per sample (in contrast with typical consumer-oriented video applications that use only 4:2:0 color sampling and 8 bits of dynamic range).
Four of the new profiles support "intra-only" applications with demands for extreme low-latency operation, simple editing, and random-access functionality.
Applications for the new profiles include studio camcorders, content creation and contribution, professional digital video recording and editing systems, studio production and post production systems, digital cinema / large screen digital imagery systems, and compression for high fidelity display systems.
