How does 1394 compare to Ethernet?
1394 multiplexes (combines) a variety of different types of digital signals, including video, audio, MIDI and device control commands, on two twisted-pair conductors (similar to that of 10base-T Ethernet). This ability to easily multiplex or combine different signal types distinguishes 1394 from other systems which transmit only a single signal type. Ethernet, for example, is typically used in data networks and requires special protocols (presently implemented only in proprietary multimedia networking systems) to transmit real-time, high-quality audio and video. In comparison, 1394 is much more flexible in its accommodation of different data types and topologies than Ethernet and other alternative networking systems. 1394 uses a “fairness” arbitration approach to assure that all devices that have information to transmit get a chance to use the bus. 1394 protocols also include device-specific commands to start and stop camcorders, VCRs and other tasks. Standard Ethernet does not provide
