Abstract: Presented herein are Tertiary Content Addressable Memory based motion estimator(s). In one embodiment, there is presented a method for encoding a picture. The method comprises addressing a first memory with one or more data words for a first prediction block, and addressing a second memory with one or more data words for a second prediction block while addressing the first memory.

Abstract: Moving picture decoding arrangements where the motion vector for the target block of decoding is calculated on a decoding side. A reference frame is selected dependent on whether candidate blocks adjacent to the target block of decoding have a motion vector for forward prediction or backward prediction. In calculating the motion vector, a median of motion vectors of the adjacent blocks is set as the motion vector. Decoding of a moving picture is performed by using information of the selected reference frame and the calculated motion vector.

Abstract: A method for compressing video operates by first deleting one or more video packets from binary train to provide a reduced binary train. Thereafter, error masking is performed on the reduced binary train to yield a corrected degraded local decoded image which is the image reconstructed on the basis of the reduced binary train and of the masking algorithm. The reduction in the binary train is validated as a function of the quality of the corrected degraded local decoded image. Lastly one of the reduced binary train or of the binary train, is selected depending on whether or not there is validation.
