Abstract

A system (and methods) for transferring multimedia information from a source location to a destination location through one or more networks, which may be different. The system has a source output which provides a first stream of information in a first format. The system also has a destination input which receives a second stream of information in a second format. A proxy transcoder server (“PTS”) is coupled between the source output and the destination input. The PTS has a transcoding module transcoding data. The PTS also has a capability module identifying a first capability of the source output and a second capability of the destination input, and selecting a transcoding process based upon the first capability and the second capability.

Claims

1. A system for transferring multimedia information from a source location to a destination location through one or more networks, the system comprising:

a source output providing a first stream of information in one of a plurality of source;

a destination input receiving a second stream of information in one of a plurality of destination capabilities;

a proxy transcoder server (“

PTS”

) coupled between the source output and the destination input, the PTS comprising;

a capability module adapted to identify the source capability of the source output and adapted to identify destination capability of the destination input;

a selection module adapted to select a transcoding process based upon the one capability of the source capabilities and the one capability from the destination capabilities;

a transcoding module adapted to use the selected transcoding process to process the first stream of information; and

one or more elements described in the specification of Exhibit 1, which has been incorporated by reference for all purposes.
