In H.264 video coding, there are a substantial number of 4x4 blocks becoming all-zeros after transformation and quantization. This is a waste of computational resources because these skipped blocks do not require forward transform and quantization. We proposed a very effective early detection of fast skipped block detections based on the theoretical(More)
The paper describes a fast MPEG-2 to H.264 transcoder by leveraging the MPEG-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(More)
