The DAVIC Standards Group

DAVIC stands for Digital Audio-Visual Council, which is an international effort to make digital communications compatible and cohesive. It aims at achieving end-to-end standardization of system interfaces. DAVIC plans to not only to define standards, but also to test all elements in the complex hierarchy of digital distribution this summer. It attempts to coordinate standard activities and to avoid duplication, especially where DAVIC members are also members in these other bodies. A set of specifications for end-to-end distribution for many different multi-media applications is expected to be submitted to the International Standards Organization (ISO) and other standards bodies by December 1995.

Aspect to be covered under DAVIC include the three key elements of the distribution chain

This includes operating systems, application program interfaces, user interfaces, program access protocols (means of tuning to particular services), data transport protocols, modulation techniques and much more. It addresses delivery of all the applications over virtually any type of network, including one-way broadcast and satellite, hybrid fiber/coax, fiber-to-the-curb, wireless and twisted-pair copper. The delivery platform even includes CDI, the interactive CD format developed by Philips. Insiders expect that killer multi-media applications will be movies-on-demand, home shopping, near movies-on-demand, delayed broadcast TV, multimedia retrieval service, broadcast TV and radio, and tele-work.

DAVIC members come from major cable, telecommunications and computer hardware and software manufacturing companies worldwide, as well as significant portions of the cable and telephone operating communities. The council is modelled on the MPEG ad hoc standards group.
