    摘要： A network device may receive a signal from a headend, wherein a bandwidth of the received signal spans from a low frequency to a high frequency and encompasses a plurality of sub-bands. The network device may determine, based on communication with the headend, whether one of more of the sub-bands residing above a threshold frequency are available for carrying downstream data from the headend to the circuitry. The network device may digitize the signal using an ADC operating at a sampling frequency. The sampling frequency may be configured based on a result of the determining. When the sub-band(s) are available for carrying downstream data from the headend to the network device, the sampling frequency may be set to a relatively high frequency. When the sub-band(s) are not available for carrying downstream data from the headend to the network device, the sampling frequency may be set to a relatively low frequency.

    摘要： In a system utilizing double wide communication channels, if a particular CPE requires a sustained rate that is greater than the bandwidth of a single channel, data to and from the CPE may be split across Channels A and B. Also, when the bandwidth requirements of a particular CPE peaks at a data rate greater than the capacity of a single channel, the CPE's data may be split across the two channels. In one embodiment, a single-wide CPE may communicate with the base station without knowing that it is communicating with a base station configured to communicate using a double wide channel.

    摘要翻译： 在使用双宽通信信道的系统中，如果特定的CPE需要比单个信道的带宽更长的持续速率，那么到CPE之间的数据可能会跨越信道A和B分裂。另外，当带宽要求 特定的CPE以大于单个信道的容量的数据速率峰值，CPE的数据可以跨越两个信道被分离。 在一个实施例中，单宽CPE可以与基站通信，而不知道它正在与被配置为使用双宽信道通信的基站通信。

    摘要： A service outlet for coupling a data unit to a wired digital data signal and for coupling a service unit to an analog service signal, for use with a service wire pair installed in walls of a building, the service wire pair concurrently carrying a wired bi-directional digital data signal and an analog service signal carried over a service signal frequency band, using frequency division multiplexing, wherein the wired digital data signal is carried over a frequency band distinct from the service signal frequency band. The outlet has a single enclosure and, within the enclosure: a wiring connector; first and second filters coupled to the wiring connector; a service connector coupled to the first filter and connectable to the service unit for coupling the service unit to the analog service signal; a service wiring modem coupled to the second filter; and a power supply coupled to the service wiring modem.

    摘要： A method and apparatus for content substitution, consistent with certain embodiments of the present invention involves receiving data representing one or more macroblocks of content, the data having at least first and second packet identifiers (PIDs) associated with first and second portions of content. The content having the first PID is placed into a data stream. An initiation flag is received indicating initiation of a PID mapping operation. The substitute macroblocks of content having the second PID is then mapped to the first PID and the mapped content is placed into the data stream. A termination flag is received indicating termination of the PID mapping operation at which point the process returns to placing content having the first PID into the data stream. The content substitution process can be used to replace advertisements, provide multiple plots, multiple endings, multiple views as well as other applications. This abstract should not be considered limiting, since other embodiments may incorporate more, fewer or different elements that those described in this abstract.

    摘要： Carrier frequencies different in frequency from each other are modulated with broadcast signals different from each other, and the thus modulated signals are transmitted through a single transmission line and are suited for reception and demodulation. A programming circuit allows programming of a plurality of different programs, with each program being able to be programmed to activate any selected receivers of a plurality of receivers, and to tune each of the selected receivers to any selected carrier frequency. The different programs are stored in a memory, and each of the receivers is connected to a speaker. A selection circuit allows a user to select any one of the different programs to output the broadcast signals at selected frequencies from selected speakers.
