Abstract: A method and apparatus in a communication system (100) for allocating and controlling data transmissions to and from communications unit (134) in communications system (100). The communication systems (100) includes a cable distribution network (106) with a base communications unit (102) and a number of downstream communications units (134) all connected to the cable distribution network (106). A plurality of channels are used to transmit data transmissions between the base communications unit (100) and the downstream communications unit (134). Uplink and downlink channels are monitored to determine channel quality for each of the channels in communications system (100). The determined channel quality is used to both initiate transfers of communications links to other frequencies and for assigning channels to various communications units (134).

Abstract: In a cable television system a system for supporting SCU return in FTTB-MDU and FTTC/FTTcab configurations. Fiber, baseband transceiver and networking capabilities are shared with data and voice portions of the system for enabling communication from the SCUs to the HE over a packet based networking system. Return packets/upstream packets are passed into the network upstream channel only when a signal is present for eliminating transmission of upstream traffic that contains no signal for conserving upstream bandwidth.

Abstract: A wireless video access apparatus 100 and wireless videophone 120 provide audio and video teleconferencing and telephony via a communication channel 103 to network 140 such as a PSTN or ISDN. A signal received by the network interface 210 from the network 140 is converted into an audio signal and a baseband video signal. The audio and video signals are wireline or RF transmitted to one or more video displays 225 or televisions. Videophone 120 receives the video signal from video transponder 115 and the audio signal from wireless base station 110. A video camera or camcorder 230 generates an outgoing video signal and audio signal. The processor 190 performs compression, decompression and protocol encoding and decoding. The telephone 295 or wireless videophone 120 may be used for call set-up or audio input and output. The video camera output may be displayed on the video displays 225 or wireless videophone in a loop-back mode of operation.

Abstract: A video access apparatus (110, 150) 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 video access apparatus (110) 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; a user interface (215) for reception of a first control signal of a plurality of control signals; and a processor arrangement (190) responsive, through a set of program instructions, and in respone to the first control signal, 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.
