Video adaptation has been considered as a promising technique to bridge the gap between network status, device capabilities and user preferences in pervasive media applications. However, conventional adaptation framework based on transcoding or multiple pre-transcoding is not competent for accommodating diversified usages and a large number of users. In this paper, the system design of a novel video adaptation system based on Intermediate video description called "Intermedia" is introduced. Intermedia is consist of multiple video signal components, such as texture, motion, structural characteristic, rate control information, ROI, as well as some semantic features. It is off-line generated and stored in the video server or media gateway. Our adaptation system is able to quickly and easily generate required bitstream from Intermedia with very low complexity to fulfill a specific adaptation requirement, e.g., bit-rate conversion, temporal/spatial resolution reduction, video summarization, region-of-interest browsing, and some multi-dimensional adaptation involving both signal level adaptation and semantic level adaptation. The satisfactory performance of our system demonstrates the effective and efficiency of our proposed video adaptation framework. |
