    摘要： A direct broadcast satellite system delivers video content to a subscriber and a CATV network is used to simultaneously provide data services to the same subscriber. Since the CATV system is not used to deliver video/television programming channels, these same channels can be used to transport downstream and upstream data signals. To provide upstream performance and immunity to noise, upstream data traffic signals are upconverted at a subscriber's cable modem for transmission by channels having center frequencies higher than 54 MHz. Cable modem circuitry combines the conventional output signal with the output of a local oscillator to raise the carrier frequency of upstream traffic before it is introduced to the CATV network. Thus, upstream traffic can be carried by channels higher than 54 MHz. This upstream signal is received by a block converter that lowers the carrier frequency back to a conventional channel frequency before processing by a standard CMTS.

    摘要： A flow bonder at a CMTS and another at a cable modem distribute packets of a service flow over multiple channels and collect them in the downstream direction respectively; vice versa in the upstream direction. The service flow may include video and data streams that are provided to the CMTS via an IP network. IP header information is stripped form video packets and remultiplexed with packets of other video streams. The remultiplexed video stream packets are combined into a composite stream, which is transported using multiple bonded-flow RF channels over an HFC. A set top box receives the composite stream and separates data from video packets based on IP information. Video packets are assembled according to information from a multiple program transport stream table based on a program selected by a user.

    摘要： A flow bonder at a CMTS and another at a cable modem distribute packets of a service flow over multiple channels and collect them in the downstream direction respectively; vice versa in the upstream direction. The collector uses a service flow identifier and a sequence number identifier inserted by the distributor into each packet of the flow to reassemble the packets into the order they left the distributor. Packets received at the collector are stored to a buffer. If a stored packet is the next to be transmitted, it is transmitted. If not, the collector waits a predetermined period until the next packet to be sent is received. If it is not received during the wait period, the previously stored packet is sent. The wait period is based on the maximum transmission time difference between any two of the multiple channels.

    摘要： A device receives packets associated with a program stream at an addressable communications port, and assigns them to one of a plurality of QAM channels. Multiplexed program packets, DOCSIS data or multimedia packets or a combination of both, are transmitted over the QAM channel. DSG messaging transports requests for content to a server, transports queries to mapping tables and returns information from the tables to a manager that, along with processors, determine which channel to use for downstream transport of the multiplexed streams. The manager assigns a connection identifier corresponding to a channel and program number combination to the packets, and sends the identifier, via DSG, to the requesting/receiving user device; the identifier instructs the user device how to tune and receive the requested packets. The identifier may use seven bits for program numbers, two for output port number and two for channel frequency.
