Abstract:
1. A digital surveillance media storage system, comprising: a media analyzer receiving a media stream and decomposing the media stream into a plurality of media segments based on scenes recorded in the media stream, each media segment of the plurality of media segments having an indicia of a starting location for the media segment in the media stream and a duration time for the media segment; an encoding format selector receiving content semantic information for each media segment of the plurality of media segments and selecting an encoding format for each media segment of the plurality of media segments from plural encoding formats based on the content semantic information for that media segment and scenes recorded in that media segment, wherein the encoding format selector selects: an encoder engine receiving the plurality of media segments from the media analyzer and encoding the media segments according to the encoding format selected by said encoding format selector, where different encoding formats are selected for different media segments; and a file writer receiving the plurality of encoded media segments from the encoder engine and storing information describing the plurality of encoded media segments for the media stream in a single media file.
