Abstract :
Two novel real-time software-based video coders, the software-based moving picture coder (SBMPC) and the popular video coder (PVC), are proposed. SBMPC uses the modified block truncation code and multiresolution-in-time sampling techniques. PVC uses the adaptive quantizer and the modified windowed Huffman coder. Both the coding speed and the compression ratio are thus made much higher than those of traditional video coders. By using the proposed coders, video quality and coding speed are good and fast enough for practical video applications. Since no compression hardware is needed in the proposed video coders, the cost and complexity of developing multimedia applications can be greatly reduced
