Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Scalable media contents, such as the new MPEG-4 scalable video codec enable to easily retrieve different qualities of the media content by simply disregarding certain media segments. The MPEG-21-based codec-agnostic adaptation approach supports this concept by introducing anXML-based bitstream syntax description (BSD) which describes the different segments of a media content. Based on this BSD, an adaptation node can intelligently adapt any scalable media (i.e., remove specific media segments) without the need for codec-specific knowledge. The adaptation approach consists of 1) transforming this BSD and 2) adapting the media based on the transformed BSD. ,  focus on the BSD transformation step and evaluate different mechanisms w.r.t. their transformation efficiency given several application scenarios. In particular,  compare the traditional style sheet-based mechanisms with a novel mechanism based on regular expressions.  discuss both mechanisms in terms of their expressiveness, and propose how to actually employ regular expressions for codec-agnostic adaptation. Finally,  quantitatively evaluate these mechanisms in different adaptation scenarios, which vary in the size and number of required BSD units.
