Abstract

Abstract A multiple input processor includes apparatus for receiving inputs from multiple sources and processing the inputs for transmission to receivers along a television cable network. The processor includes an RF modulator to convert audio signals from signal sources to radio frequency signals for broadcasting through the cable TV system. A microcomputer in the processor processes signals received from multiple sources and selectively transmits the signals through the modulator, The processor includes an audio bus interconnecting the signal-sources and processor to permit receiving, processing, and transmission of audio signals. A telephone interface is connected to the audio bus to permit transmission of signals from a telephone line to the computer, as a separate signal source, and to permit transmission of signals from the audio bus to the telephone line for reporting and other auditing purposes. A modem is interfaced with the audio bus to permit self-diagnosis and testing, as well as transmission of reports from self-testing.
