SYSTEM AND METHOD FOR REAL-TIME TRANSCODING OF DIGITAL VIDEO FOR FINE GRANULAR SCALABILITY |
摘要 |
A video transcoder (500) is presented for transcoding a previously coded digital video data stream into a layered stream consisting of a base layer having a lower data rate than the original source stream and an enhancement layer encoded using Fine-Granular Scalability (FGS) techniques. The video transcoder (500) comprises an efficient means for re-encoding existing digital video into FGS multilayer video to provide variable levels of displayed picture quality under conditions of changing bandwidth degradation in wireless and/or wireline networks.
