Overview of Still-picture and VideoCompression Standards

Abstract

This paper discusses current video compression techniques and presents an overview of the existing video compression standards and standards to be. The standards discussed here are standards defined by dedicated committees as well as de facto standards. 1 Introduction In the past years a number of compression standards have emerged and a number is now being developed. Although it would be useful to use only one general video compression standard, a growing number of standards is developed because of enhanced processing power, dedicated hardware, new compression techniques, and networks with different bandwidths. Each compression standard supports a specific video application. It is difficult to choose the correct compression standard for a specific application. As is true of compression in general that there does not exist one best compression algorithm, the same is true of video compression: there is no best standard. Some applications require fast real-time encoding, at the cost o..
