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.
