Abstract:
A method for encoding a sequence of video frames comprising:analyzing the sequence of video frames to derive information on at least one characteristic thereof, said at least one characteristic comprising at least one of an intraframe characteristic or an interframe characteristic;encoding the sequence of video frames employing at least one controllable parameter;buffering the sequence of video frames and controlling timing of said encoding of the sequence of video frames so that for each frame of at least some frames of said sequence of video frames said analyzing precedes said encoding to derive said information on the at least one characteristic relative each frame of said at least some frames of the sequence of video frames prior to said encoding of the frame; anddynamically adapting said encoding of the sequence of video frames using said information on the at least one characteristic thereof to adjust said at least one controllable parameter employed in encoding the sequence of video frames, wherein said encoding is dynamically adaptive to change in the at least one characteristic of the sequence of video frames.
