IEC 61883-1:2008 specifies a digital interface for consumer electronic audio/video equipment using IEEE 1394. It describes the general packet format, data flow management and connection management for audio-visual data, and also the general transmission rules for control commands. It defines a transmission protocol for audio-visual data and control commands which provides for the interconnection of digital audio and video equipment, using IEEE 1394. This third edition of IEC 61883-1 cancels and replaces the second edition, published in 2003 and it constitutes a technical revision. The significant technical changes with respect to the second edition are:
- allocation of a new FMT code for the 1394 Trade Association specification '601 over 1394';
- Clarification of the meaning of FMT code;
- harmonization of IEC 61883-1 with IEEE 1394.1 for speeds over S400. This bilingual version (2012-08) corresponds to the monolingual English version, published in 2008-02.
