【 摘 要 】

Recently, an end-to-end framework called SSM, for fully content agnostic adaptation of scalable bit- streams or certain non-scalable bit-streams operating in scalable modes, has been proposed. SSM develops metadata to describe a scalable bit-stream in terms of adaptations that can be conducted on it to obtain lower versions, and also allows recipients to specify usage environment constraints based on which a piece of content is to be adapted by a network adaptation engine. Based on this framework, a fully format agnostic universal adaptation engine software has been developed. In this report, we present adaptation use cases involving several different standard and non-standard bit-stream formats (MPEG-4, JPEG2000, MC- EZBC), and show how the universal adaptation engine adapts them. The SSM schema and software versions considered is 2.0. 76 Pages
