Audio/video channel bonding by chunk

摘要

Different data communication architectures deliver a wide variety of content, including audio and video content, to consumers. The architectures employ channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, the communication architectures distribute video programming in the form of MPEG2 TS packets, flagged by marker packets, in a round-robin manner across the communication channels. Channel bonding synchronization information may be present in packets defined above the data-link layer or added to fields within data-link layer frames.

1. A system comprising:
a statistical multiplexer input interface configured to receive content; output interfaces to individual communication channels; and circuitry in communication with the statistical multiplexer input interface and the output interfaces, the circuitry configured to:
determine which of the communications channels to include in a bonded channel group;obtain program packets comprising the content from the statistical multiplexer input interface; responsive to the content within the program packets, determine a chunk size for chunks of multiple program packets; distribute a set of marker packets across the output interfaces, the marker packets comprising a group number that identifies the set of marker packets to which the marker packets belong; and distribute the chunks across the communication channels in the bonded channel group, preceded by the marker packets.
