DAVIC, Digital Audio Video Council, was founded in 1994 with the aim of promoting the success of interactive digital audio-visual applications and services by promulgating specifications of open interfaces and protocols that maximise interoperability, not only across geographical boundaries but also across diverse applications, services and industries. It was a non-profit international organization based in Switzerland. DAVIC was closed, according to its statutes, 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. The four major sets of specifications culminated in 1999 with the 1.4 version. The 1.5 version of DAVIC was a set of additional tools and service definitions opening the road 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 was 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. ==1.4.1 specifications== * Description of DAVIC Audio-Visual Functionalities * System Reference Models and Scenarios * Service Provider System Architecture and Interfaces * Delivery System Architecture And Interfaces * Service Consumer System Architecture * Management Architecture and Protocols * High and Mid Layer Protocols * Lower Layer Protocols and Physical Interfaces * Information Representation * Basic Security Tools * Usage Information Protocols * Systems Dynamics, Scenarios and Protocol Requirements * Conformance and Interoperability * Contours: Technology Domain 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「DAVIC」の詳細全文を読む スポンサード リンク
