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 data stream representing a media signal at a given level of compression is processed just before the data stream enters the internet. A less compressed data stream representing the same media signal is generated transmitted through the internet. Due to the lower level of compression, the underlying media signal is less sensitive to packet loss in the internet and, as a result, the media signal that arrives at the receiving end will tend to be more continuous and clear.

[ What is claimed is:] [1.] In a telecommunications system of the type including a computer network interconnected to a communications link via a first network access server, said communications link interconnecting source equipment to said first network access server, wherein said computer network is further interconnected to a remote communications link via a remote network access server, a transmission method comprising, in combination, the following steps:at the first network access server, receiving via said communications link a first data stream representing at a first level of compression a media signal provided by said source equipment;at the first network access server, processing said first data stream and generating a second data stream representing said media signal at a second level of compression less than said first level of compression;at the first network access server, forwarding said second data stream in said computer network destined for receipt by a remote user;at the remote network access server, said second data stream;at the remote network access server, processing said second data stream and generating a third data stream representing said media signal at a third level of compression greater than said second level of compression; andat the remote network access server, forwarding said third data stream along a remote communications link to said remote user.
