ABSTRACT:
A video access apparatus (110, 150, 160) provides for audio and video teleconferencing and telephony via a first communication channel (103) having communication with a network (140), such as the public switched telephone network or an ISDN network. The network (140) is preferably an intelligent network (115) having an intelligent peripheral (125) which provides for user interface functionality, for call control and configuration, and for interworking functions. The video access apparatus (160) includes a wireline network interface (210) for reception of a first protocol signal to form a received protocol signal and for transmission of a second protocol signal to form a transmitted protocol signal; a radio frequency modulator/demodulator (205) to convert a baseband output video signal to a radio frequency output video signal and to convert a radio frequency input video signal to a baseband input video signal; and a processor arrangement (190) responsive, through a set of program instructions, to convert the received protocol signal to the baseband output video signal and to an output audio signal, and to convert the baseband input video signal and an input audio signal to the second protocol signal.
