An Overview of VC-1

摘要

VC-1 is a state-of-the-art video compression format that provides highly competitive video quality, from very low through very high bit rates, at reasonable computational complexity. The technology includes several innovations to improve the rate-distortion performance envelope of the format and to provide additional tools for perceptual quality improvement. This paper describes some of the key innovations of VC-1 that contributes to its quality and complexity advantages. The focus of this paper is on those tools which are unique-to VC-1, and differentiate it from other video compression standards.
