Title:
MULTIPLEXING OCTETS FROM A DATA FLOW OVER MPEG PACKETS
Document Type and Number:
WIPO Patent Application WO2006004828
Kind Code:
A3
Abstract:
Multiplexing of information from a plurality of information flows into fixedlength packets such as, but not limited to, MPEG packets allows efficient utilization of bandwidth and also can be used to reduce transmission latency. In addition, utilizing MPEG packets and transport streams for octet multiplexing allows the packets carrying octet-multiplexed data to easily be integrated with other MPEG packets for other services that are commonly found in cable transmission networks of all coax, hybrid fiber coax, and/or all fiber. Moreover, the multiplexing techniques described herein will work in both wired (or constrained media) and wireless (or free-space propagation) environments. The multiplexing/demultiplexing of octets using MPEG packets generally is described by mappings that specify the use of octets in MPEG packets. Changes to allocations in a map generally should be propagated in a way that reliably ensures that both the transmitter and receiver have a consistent view of the octet mappings.
