Abstract

Methods and apparatus for associating each data packet in a media stream with logic corresponding to a particular quality-of-service (QoS) and/or error correction requirement. In an exemplary embodiment, each packet in the media stream is assigned a frame tag which designates a particular quality-of-service and/or error correction scheme for the corresponding packet. At least a portion of each packet is encoded according to the packet's designated quality-of-service as indicated by the frame tag. A receiver accesses the frame tags from within the transmitted media stream in order to determine the appropriate means for processing or decoding the encoded portion of each packet. In this manner, each packet within the media stream can have its own quality-of-service and/or error correction requirements and processing, thereby enhancing link efficiency and better enforcing QoS policy across the system.

First claim

What is claimed is:

1. A method of communicating a plurality of data packets of a plurality of different data packet types by a computing device, the method comprising the computing device:
dynamically assigning at least one quality-of-service (QoS) class and at least one forward error correction (FEC) mode to each data packet of at least a portion of the plurality of data packets based on a data packet type of a corresponding data packet;
generating one or more elements indicat…
