ABSTRACT:
A system for deinterlacing encoded video data includes a demultiplexer for receiving the encoded video data and producing motion information and compressed video data corresponding to the encoded video data. A motion compensated predictor generates predicted image data based on the motion information corresponding to the encoded video data. A variable length decoder decodes the compressed video data corresponding to the encoded video data to produce residual data. An adder combines the residual data and the predicted image data to generate an interlace field and a memory stores picture data corresponding to the interlace field. A controller processes the motion information and generates motion vectors and a control signal corresponding to the motion information. A motion compensated deinterlacer manipulates the picture data corresponding to the interlace fields from the memory according to the motion vectors and the control signal to generate a corresponding deinterlace picture.
