This research proposes a block-based video codec design with two objectives. The first goal is to propose a method for intraframe that improves the rate-distortion (peak signal-to-noise ratio versus bit rate) of a fixed-size transform encoder. The proposed method uses three integer transform sizes (4x4), (8x8), and (16x16). The codec also adopts H.264-like spatial prediction to intraframe encoding. For simplicity of the design, Huffman variable-length code is used as entropy encoding. For intraframe encoding, the simulations show rate-distortion improvement over JPEG and JPEG2000. In some test sequences, the simulations also show improvement over H.264 (baseline profile at low complexity mode without rate-distortion optimization) with a small increase of operations on each macroblock at the decoder side.Different from the previous work, this research utilizes two sets of three integer transforms, applying {(16A—16), (8A—8), (4A—4)} ... a Cb-blue color difference component, and a Figure 1.1 Test video sequence, Football, common intermediate formatanbsp;...
