Abstract

This paper concerns the extraction methodology and usage of MPEG-7 metadata for video transcoding. The idea of the MPEG- 7 descriptors presented within this paper is to give by mens of MPEG-7 metadata Transcoding Hints to a transcoder regarding Motion and Encoding Difficulty. These transcoding hints can be used at the transcoder (1) to preserve the visual quality in terms of PSNR, (2) to modify the GOP structure for efficient storage and retrieval for fast video browsing, while (3) reducing the overall computational complexity significantly.
