Abstract:
A method of encoding a video signal in order to obtain an encoded video stream having seamless splice points, said encoded video stream having a presentation order and encode order, said method comprising the steps of:a) allocating a target number of bits to a first video frame of said video signal that precedes a desired splice point in presentation order; b) determining an estimated decoding delay for a second video frame of said plurality of video frames that follows said desired splice point in encode order; c) determining a correction factor based upon a difference between said estimated decoding delay and a splice point decoding delay for said first video frame, the splice point decoding delay being a delay necessary to achieve a seamless splice point at said desired splice point; d) adjusting said target number of bits allocated to said first video frame based upon said correction factor to obtain an adjusted number of bits for said first video frame; and e) encoding said first video frame based upon said adjusted number of bits.
