    Abstract: In one example, a Cable Modem Termination System (CMTS) sends first bandwidth allocation messages to a first upstream transmit interface on a cable modem and send second bandwidth allocation messages to a second upstream transmit interface on the cable modem. The bandwidth allocation messages indicate transmit windows for the cable modem to range over the interfaces. The transmit windows included in the first bandwidth allocation messages are spaced based on receipt of ranging requests from the second upstream transmit interface, and the transmit windows included in the second bandwidth allocation messages are spaced based on receipt of ranging requests from the first upstream transmit interface.

    Abstract: A control data transmission and reception period of, for example, 1 ms is provided for each frame of a digital broadcast signal. The digital broadcast signal is intermittently transmitted. In the intermittent transmission, the transmitting device stops the digital broadcast signal from being sent during the control data transmission and reception period. At the same time, control data is transmitted during the control data transmission and reception period. In other words, a beacon signal is sent from a transmitting device to a wireless television receiver as control data, between the intermittent transmissions of the digital broadcast signal. Having received the beacon signal, the wireless television receiver returns a request signal to the transmitting device. As a result, communication between the transmitting device and the wireless television receiver can be established.

    Abstract translation: 为数字广播信号的每一帧提供例如1ms的控制数据发送和接收周期。 数字广播信号被间歇地发送。 在间歇发送中，发送装置在控制数据发送接收期间停止发送数字广播信号。 同时，在控制数据发送和接收期间发送控制数据。 换句话说，在数字广播信号的间歇发送之间，将信标信号作为控制数据从发送装置发送到无线电视接收机。 接收到信标信号后，无线电视接收机向发送装置返回请求信号。 结果，可以建立发送装置与无线电视接收机之间的通信。

    Abstract: A transmitter generates MUX-PDUs for video, audio, data, and/or control streams based on a fixed PHY packet size such that all or a substantial percentage of the MUX-PDUs conform to the PHY packet size. The MUX-PDUs have variable sizes and are mapped to PHY packets such that (1) each MUX-PDU that is smaller than the PHY packet size is sent in one PHY packet and (2) each MUX-PDU that is larger than the PHY packet size is sent in a minimum number of PHY packets. Each MUX-PDU is padded with one or more null MUX-PDUs and/or one or more padding bytes, if needed, to obtain the PHY packet size. Each PHY packet is sent in one transmission time interval (TTI) to a receiver. The receiver performs the complementary processing on the received PHY packets to recover the MUX-PDUs. The receiver forwards each valid MUX-PDU and discards any padding.
