DAVIC, Digital Audio Video Council, was an organisation founded in 1994 with the aim of promoting interactive digital audio-visual applications and services by promulgating specifications of open interfaces and protocols that maximise interoperability across diverse applications, services and industries. It was a non-profit international organisation based in Switzerland. DAVIC was closed after 5 years of activity.
At the most, DAVIC had 222 companies from more than 25 countries as members, although over its life 295 organisations were members at some stage. It represented all sectors of the audio-visual industry: manufacturing (computer, consumer electronics and telecommunications equipment) and service (broadcasting, telecommunications and CATV), as well as a number of government agencies and research organisations.
DAVIC produced four major sets of specifications up to the 1.4 versions in 1999. The 1.5 version of DAVIC was a set of additional tools and service definitions towards the setting of IP based audiovisual services such as the TV Anytime and TV Anywhere services. Version 1.3.1 was re-structured and approved as an ISO/IEC standard and technical report (ISO/IEC 16500 and ISO/IEC TR 16501).
The management of DAVIC had proposed the continuation beyond the 5-year date with a program of work centred on two projects: TV Anytime and TV Anywhere. The membership did not support the continuation of DAVIC but the idea of TV-Anytime continued as a new organisation.
