Abstract

A system and method for scaling a video system, such as an MPEG-2 video decoder, utilizing an improved data pruning implementation. A scalable data processing system is provided, comprising: a sequential data path for processing multimedia data, including a first processing module and a second processing module; a scalable application for scaling the second processing module; and a data pruning system positioned prior to the first processing module that causes a portion of the multimedia data associated with the scaling application to be truncated.
