Apparatus and methods for lightweight transcoding

Abstract

Apparatus and methods for lightweight transcoding. In one embodiment, a minimal function transcoder is disclosed which supports multiple devices requiring various video formats. Transcoding functionality may be downloaded to an existing device and comprises using an intermediate set of data resulting from a partial decode of an input stream that is temporarily stored until all transformation operations have completed. Premises devices register to the transcoder and the transcoder transcodes content requested by the registered devices (i) upon detection that the registered device is 'in use'; (ii) at the time of original content playback or broadcast; and/or (iii) at a time prior to a previously scheduled time of intended use. The transcoder exploits the similarities between the mechanisms by which the various encoding formats and, in one variant, ignores some of the features of the more advanced content formats to arrive at a “just-in-time” or “near real-time” transcoded content.
