1394 High Performance Serial Bus: The Digital Interface for ATV

"1394 High Performance Serial Bus: The Digital Interface for ATV" is a paper that was written for and presented at the International Conference on Consumer Electronics held in Chicago, June 6-9, 1995. The paper has been published in the IEEE Transactions on Consumer Electronics, August 1995, Volume 41, Number 3, pages 893-900. The authors are Adam Kunzman and Alan Wetzel, both with TI in Dallas, Texas.

This paper describes the fundamentals of the IEEE 1394 cable (physical layer) environment, and its ideal characteristics for carrying time critical MPEG-2 transport packet streams. MPEG-2 transport streams are the basis for the US Grand Alliance digital ATV systems. MPEG-2 transport streams are also the basis for the European DVB digital television systems, and are now in use by direct broadcast satellite (DBS) systems. The standardized physical, link, transaction and management layers are described, along with isochronous operation and isochronous packet formats. To facilitate MPEG-2 transport over 1394, a Common Isochronous Packet (CIP) header is added. The CIP header parameters include a time stamp field containing the 1394 system-wide cycle time. The 1394 time stamp allows the receiver to remove any delivery delay variations from the incoming MPEG-2 transport stream.

Much of this material was included in the "HyperLynx" proposal made by TI to the EIA R-4.1 Committee in February, 1995. The R-4.1 has since (September, 1995) elected to use IEEE 1394 as the interface for US ATV systems.
