A prototype of a novel television set (TV) with personal computer (PC) capability is presented. In addition to fundamental TV functions, the system provides three PC functions: CD playing, teletext viewing and WWW (World Wide Web) browsing. This paper describes the user interface that the user can operate without knowledge of PC. Also, a scan-line conversion method to display clear PC images on a TV monitor is described.

In the search for lower bit rate image compression and representation, a new video motion estimation technique (VMET), that considers video object translation, as well as rotation, and planar multilayering, is described. This new concept uses a modified multipopulation coevolutionary genetic algorithm (MMCGA), that receives the video objects of segmented reference images, and outputs the corresponding motion and layer information, using object and layer genotypes. Genetic operation strategies of reproduction, crossover, mutation, and dominance are applied recurrently in order to create successive generations of genomes with much better fitness, until convergence, or the maximum allowed number of generations is reached. For the increase of prediction accuracy and convergence speed, a lifetime fitness strategy is used. Simulations with synthetic images have shown very encouraging results with the proposed video motion estimation technique, which competes favorably with respect to the conventional algorithms in accuracy, effectiveness, robustness, simplicity and speed.

We have developed a single chip motion JPEG codec LSI that can compress and decompress VGA-size (640 pixels/spl times/480 lines) JPEG images at the rate of 30 frames per second simply by connecting a single external buffer memory chip. The LSI can control compression ratio control technique to store a fixed number of images when there is limited memory capacity, and it compresses data stored in the frame buffer to enable high-speed signal processing without the use of high-speed image memory. The JPEG codec core is small (40000 gates) and power consumption is low (220 mW), making it well suited to a wide range of image processing applications in consumer products.

We have developed a programmable video codec system using a video codec DSP called VDSP1 X for low-bit-rate communication which performs realtime encoding and decoding using discrete cosine transform (DCT)-based algorithms, such as ITU-T H.261, H.263, and wavelet-based subband encoding algorithms. This system realizes real time encoding and decoding for QCIF frame sizes for both DCT-based algorithms and wavelet-based subband encoding algorithms in the same environment.
