1. A multimedia distribution device comprising:
- a nonvolatile memory storing;
a compressed media signal comprising plurality of scenes each comprising a number of temporally adjacent frames in which at least two scenes are selectively compressed using at least two different codecs from a codec library, wherein the at least two different codecs are automatically selected by repeating, for each of the plurality of scenes, the steps of;
testing a plurality of different codecs on the scene to determine how each codec encodes the scene in terms of quality and compression level; and
automatically selecting the codec that produces the highest quality encoded output for the scene according to a set of criteria without exceeding a bandwidth constraint; and
a plurality of codec indicators specifying which codecs from the codec library were used to respectively compress each scene within the compressed media signal.

Abstract
A multimedia distribution device includes a nonvolatile memory that stores a compressed media signal in which at least two scenes are selectively compressed using different codecs from a codec library, the codecs being automatically selected to produce a highest compression quality for the respective scenes according to a set of criteria without exceeding a target data rate. The nonvolatile memory also stores a plurality of codec indicators specifying which codecs from the codec library were used to respectively compress each scene within the compressed media signal.

11. A method for distributing multimedia content comprising:
-
obtaining a media signal comprising a plurality of scenes, each scene comprising a number of temporally adjacent frames; repeating for each of the plurality of scenes; testing a plurality of different codecs from a codec library on the scene to determine how each codec encodes the scene in terms of quality and compression level; automatically selecting the codec that produces the highest quality encoded output for the scene according to a set of criteria without exceeding a bandwidth constraint; storing the scene encoded using the selected codec in a nonvolatile memory with a codec indicator specifying which codec from the codec library was used to compress the scene, wherein at least two scenes are encoded using different codecs from the codec library. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
