Abstract
Efficient video content adaptation requires techniques for content analysis and the development of appropriate mechanisms for content scaling in terms of the network properties, terminal devices characteristics and users´ preferences. In this paper, we propose an adaptive optimal rate distortion scheme able to allocate different priorities for each video object with respect to the users´ needs, network platform capabilities and terminal characteristics without violating the target bit rate of the sequence. In this paper, we consider that video objects have been already detected by a content segmentation algorithm. The proposed scheme minimizes the effects of objects on non-interest compared to objects of interest.
