8 1394 Bus Specifications u Serial (not parallel) bus u Cable and backplane bus u Automatic assignment of bus topology, ID Ø startup Ø hot-plug u Unified address space: Ø 10 bits per bus Ø 6 bits for node ID Ø 48 bits for memory inside node

9 Topology Daisy Chain Star 5 nodes 4 hops 11 nodes 4 hops

10 1394 Cable Lengths, Speeds u Copper 4.5 meters / 400 Mbps Ø Oki 20 meters/s Meters/s200 Ø two twisted pair (optional: two power wires) Ø : up to 16 hops, each 4.5 m, = 72 m u Cat5 100 m / S100 (100 Mbps) u on Cat5 (currently under study) u POF 50 m / S100, S200 u HPCF 100 m / S100, S200 u GOF 500 m / S400, S800, S1600 (S3200)

24 Protocol streaming layer overview u Transmitting Ø Creating a packet from n samples Ø Provide time stamp at specified interval Ø Enough samples arrived to make a packet? u Receiving Ø Reassemble a stream Ø Playback so the sample is rendered as the associated time stamp indicates.

25 Example Introduction to mlan (November 2003) Protocol Streaming layer overview Single isochronous channel Seq. A Audio Seq. B Seq. C MIDI Seq. D

26 Protocol Streaming layer overview Audio data or MIDI over 1394 Playback timing

27 Protocol Streaming layer overview audio streaming Transmission Sample count progress.. Cycle time Time stamps are provided for every certain number of samples. Time stamp should represent render-time not the time of transmission.
