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.
