Developments in videocompression and VLSI technologies are producing revolutionary changes in the television industry. Television signals worldwide are beginning to be compressed, encoded and transmitted using digital means. Using digitalcompression, encoding and transmission techniques has the advantage of better bandwidth utilization, flexibility and ease of integration with other digital data, and an overall higher quality of video at the receiver. The purpose of this paper is two-fold. Firstly, an introduction to videocompression in the context of emerging digital television standards is provided. The important role played by International Standards, specifically MPEG, in the development of digital television systems is discussed. Secondly, current trends in the use of compression in the development of digital television for deployment in the United States and Europe, and the participation of Philips in these new applications, are discussed.

The large quantity of data associated with visual information necessitates the use of compression techniques. In this paper, we propose a novel approach (compressed domain technique) to implement spatial scalability directly on the compressed image/video data. In contrast to the spatial domain technique (baseline for comparison), the proposed technique removes the unnecessary decompression and re-compression procedures. The computational complexity is greatly reduced by using certain approximations. We note that depending on the image/video content, only marginal quality degradation (almost unnoticeable subjectively) may be introduced. Simulation results confirm the substantial reductions in computational complexity of the proposed technique at a comparable performance to the spatial domain technique.

This paper presents a new method, called Spatial Dynamic Motion Compensation (SDMC), which applies the concept of global motion to the coding of motion trajectory information for the purpose of side information reduction in digitalvideo signal compression. The experimental results of the SDMC algorithms presented in this paper have shown that the new method yields significant improvements in terms of bit rate reduction of motion information over the method used in MPEG-1, while maintaining a comparable reconstructed picture quality, when the video sequences possess significant global translational motion.
