The IEEE Standards Board recently approved the 1394-2008 specification. 1394-2008 combines all IEEE-1394 specifications developed since the audio-video multimedia standard was founded in 1994. The 1394-2008 High Performance Serial Bus Standard updates and revises all prior 1394 standards dating back to the original 1394-1995 version, and including 1394a, 1394b, 1394c, enhanced UTP, and the 1394 beta plus PHY-Link interface. It also incorporates the complete specifications for S1600 (1.6 Gigabit/second bandwidth) and for S3200, which provides 3.2 Gigabit/second speeds.
IEEE-1394, also known as FireWire and i.LINK, has been designed into a wide range of consumer, computer, industrial and other products since its inception, and is emerging as a powerful new standard for use in automotive entertainment systems.
The team dealt with errata remaining from prior specifications, and harmonized all message types, including fields that had been used in related specifications such as the 1394.1 bridging specification, and IDB-1394, which was developed as the original automotive entertainment standard. Not incorporated is work currently underway within the 1394 Trade Association working groups, including 1394 over coax and the new 1394-Automotive specification due later this summer.
