Abstract

In a situation where many different output formats tailored to certain environments must be generated upon request from a single generic storage format of a video object, transformations in real-time must be available. The paper introduces the building blocks of a system that can provide such transformations. A non-real-time preparation phase produces a layered lossless format and also does content analysis. Meta-data extracted here are later used to control and simplify the transcoding process performed in real-time. The worst-case-to-average ratio is reduced significantly, allowing for better scheduling, reduced buffer sizes, and higher admission rates. The paper describes the details of this approach and provides an evaluation. Copyright 2005 ACM.
