IEEE 1394-cable's home digital network interface of choice

The OpenCable set-top terminal will serve as the gateway to the cable network's programs and services, including support for digital SDTV and HDTV on cable. The OpenCable set-top initiative has selected the versatile IEEE 1394 high-performance serial bus as the bridge between the diversity of applications delivered to the cable set-top and consumer electronic devices such as television receivers. The set of requirements for the set-top to digital television (DTV) interface are described. The implementation of these requirements embodied in the OpenCable interface design are presented.
