Abstract
Different data communication architectures receive a wide variety of content, including audio and video content, for consumers. The architectures employ channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, the communication architectures receive distributed video programming in the form of MPEG2 TS packets, flagged by marker packets. Channel bonding synchronization information may be present in packets defined above the data-link layer or received in fields within data-link layer frames.
Claims1
A system, comprising:
- a first interface configured to receive, from a channel in a bonded channel group:
- bonding information for the bonded channel group, the bonding information encapsulated at a first layer of a communication protocol stack;
- and
- program data in a payload encapsulated at a second layer of the communication protocol stack that is different than the first layer;
- a collator coupled to the first interface, the collator configured to:
- extract the bonding information from the encapsulation at the first layer;
- and
- generate a packetized stream at the second layer, the packetized stream including the bonding information and the program data.
