    摘要： Systems and methods are disclosed for providing reverse signals from a plurality of DHCTs to a downstream modulator that is located in the headend facility. The present invention includes a single wire return device (SWRD) that receives RF modulated signals, dynamically determines the address of the associated modulator, and converts the signals into Ethernet signals. The Ethernet signals are subsequently provided to the headend facility via fiber cable.

    摘要： Atomic channel change in a switched digital video (SDV) system. A set-top box (STB) sends join and leave message commands to a SDV device when requesting a channel change. If one of the IGMP message commands does not reach the SDV device, oversubscription can occur. A combined join and leave message ensures that a join command is performed only when a leave command is also performed. If the single message does not reach the SDV device, the STB resends the command.

    摘要： Expedited digital signal decoding. A multicast or unicast data stream is sent from a headend to a set-top box at a natural rate. A decoder buffer in the set-top box begins to fill. Once the buffer is partially full, a decoder begins to decode the data at a rate lower than the natural rate. Images are displayed to the user before the buffer is full, allowing for a faster channel change.

    摘要翻译： 加速数字信号解码。 多播或单播数据流以自然速率从头端发送到机顶盒。 机顶盒中的解码器缓冲区开始填充。 一旦缓冲器部分满载，解码器开始以低于自然速率的速率解码数据。 在缓冲区已满之前，会向用户显示图像，从而可以更快地改变频道。

    摘要： A method and system for inserting television commercials that are selected according to the unique interests and purchasing habits of viewers in individual households, or the relative location of the household within a local broadcast area. The present system provides a cable or satellite television set top box that stores a plurality of television commercials for products or services that have been found to be of interest to viewers in a household that uses the set top box. At commercial breaks during the broadcast of network television programs, the television network indicates when the set top box is authorized to insert a stored television commercial instead of a broadcast commercial. If the set top box locates a locally stored commercial that is appropriate for the television program and the user, the commercial is inserted into the commercial break.
