Abstract
A video access apparatus (110, 150, 750, 850) provides for audio and video teleconferencing and telephony via a first communication channel (103) coupled to a primary station (105) having communication with a network (140), such as the public switched telephone network or an ISDN network. The video access apparatus (110) includes a video network interface (210); a radio frequency modulator/demodulator (205); a user interface (215); and a processor arrangement (190). A videophone apparatus (700, 800) is coupleable to a video access apparatus via a second communication channel for video reception and transmission, and via a third communication channel for audio reception and transmission. The videophone apparatus includes a video monitor (715), a camera interface (235), a video camera (720), and a telephony module (710). Multiple videophone apparatuses (700, 800) may be used simultaneously, and multiple video signals from the videophone apparatuses (700, 800) may be multiplexed and combined into one composite video signal for transmission to the network (140).
