Abstract
Video scalability plays an increasingly important role in the disclosure of digital video content. Currently, the scalable extension of the H.264/AVC video coding standard (SVC) is being finalized, which provides scalability layers for state-of-the-art H.264/AVC video streams. Existing video content that is coded using single-layer H.264/AVC, however, cannot benefit from the newly developed scalability features. Here, we discuss our architecture for H.264/AVC-to-SVC transcoding, which is able to derive SNR scalability layers from existing H.264/AVC bitstreams. Results show that the rate-distortion performance of our architecture approaches the optimal decoder-encoder cascade within 1 to 2 dB. Timing results indicate that intelligent conversion techniques are required, and that transcoding can significantly reduce the required computation time.
