Abstract

A multimedia communication arrangement communicating video and at least one other data type using a communication channel includes a first interface arrangement for communicating video and the at least one other data type using the communication channel. A second interface arrangement exchanges data with, and provides power to, at least one of a variety of peripheral devices. A video data signal processor circuit processes the video data and sends the video data along with the at least one other data type over the first interface arrangement and communicates with the peripheral devices over the second interface arrangement.
