1. A method for processing a multimedia stream, comprising:
- rendering, from the multimedia stream, a first compressed stream using a first compression algorithm;
in parallel therewith, rendering, from the multimedia stream, at least a second compressed stream using a second compression algorithm;
evaluating at least the first and second compressed streams; and
based on the evaluating act, transmitting a selected one of the compressed streams.

Abstract
A multimedia stream is compressed in parallel by plural encoders, the compressed stream outputs of which are dynamically evaluated for merit. A best one of the compressed streams is transmitted, along with information regarding the particular compression algorithm that was used, so that the receiver'"'"'s decoder can decompress the stream for presentation.

14. A system for encoding an original multimedia stream for transmission, comprising:
-
a first encoder encoding the original stream using at least a first encoding algorithm to render a first encoded stream;
a second encoder encoding the original stream using at least a second encoding algorithm to render a second encoded stream; and
a processor selecting one of;
the first and second encoded streams, to render a selected stream representative of the original stream. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
