Claims
- 1. A motion compensated video processing method, comprising the steps of:
- selecting a number of video frames including an I frame in a video frame group comprised of plurality of I frames; and
- replacing said "I" frame by a "B" frame that is calculated as a difference between said "I" frame and the average of two neighboring "I" frames being located on either side of said "I" frame.
- 2. The method according to claim 1, further comprising applying weighting to predetermined frames of said video frame group prior to selective summation.
- 3. The method according to claim 2, further comprising decoding said video frame group by applying weighting to said "B" frame prior to selective summation in order to reconstruct the selected video frames.
- 4. The method according to claim 3, wherein said decoding is of open-loop type, and said weighting is applied by adjusting a quantization value for reduced noise.
- 5. The method according to claim 1, further comprising decoding said video frame group by applying weighting to said "B" frame prior to selective summation in order to reconstruct the selected video frames.
- 6. The method according to claim 5, wherein said decoding is of open-loop type, and said weighting is applied by adjusting a quantization value for reduced noise.
