Abstract:

A digital central control unit is connected in a master/slave relationship to a plurality of audio, video, and data components, at least one of which may be an analog component. A decoder digital-to-analog unit is positioned at the input of all analog components so that signals transmitted to them from the central control unit are not decoded and converted to analog signals until after the transmission has been completed. An encoder analog-to-digital unit for converting analog signals to digital signals is positioned at the output of each analog component so that their respective analog signals are in encoded digital format when being transmitted to the central control unit. The network is thus all-digital and is therefore not subject to the limitations of networks having analog transmission lines.
