A method and apparatus for improving the speed and quality of end-to-end data or real-time media transmissions over an internet is disclosed. A media stream being transmitted to the internet is channel coded at the edge of the internet in order to free upstream bit rate for use in source coding the media. The channel coded media stream may then be decoded at a remote edge of the internet to recover lost packets.

[ We claim:] [44.] In a telecommunications system of the type including a computer network interconnected to a first telephone link via a first network access server and interconnected to a second telephone link via a second network access server, said first telephone link interconnecting a first user device to said first network access server, and said second telephone link interconnecting a second user device to said second network access server, a transmission method performed at said first network access server comprising, in combination:receiving via said first telephone link a first data set including a first set of payload transmitted from said first user device;processing said first data set and thereby generating a first coded data set comprising (i) said first set of payload and (ii) a first set of redundancy information indicative of said first set of payload;forwarding said first coded data set onto said computer network destined for receipt by said second user device;receiving from said computer network a second coded data set comprising (i) at least a portion of a second set of payload transmitted from said second user device and (ii) a second set of redundancy information indicative of said second set of payload;determining whether said second coded data set is missing a portion of said second set of payload;in response to said second coded data set missing a portion of said second set of payload, processing said second set of redundancy information and thereby extracting said missing portion; andgenerating an output data set comprising payload carried by said second coded data set, and forwarding said output data to said first user device.
