摘要：
The paper describes a fast MPEG-2 to H.264 transcoder by leveraging the WEG-2 metadata set to reduce the computational complexity of the H.264 encoding process. With the proposed fast transcoding algorithms, our software-based transcoder can perform real-time transcoding a MPEG-2 movie from a DVD disc (at D1 resolution and full frame-rate) and simultaneously performing RTP/UDP streaming of the H.264 video with AC-3 audio over IP networks using only a 1.6 GHz PC notebook. We can achieve about 20-30% faster than the full re-encoding method even at the same target bit-rate and without visible quality degradation. Benchmarking with existing software systems has shown similar results.
