Scalable video coding (SVC) is desirable for video applications in heterogeneous environments where users have a variety of terminals. Because motion-compensated prediction is used in SVC codec, when SVC video is transmitted over loss-prone networks, the decompressed video can suffer severe visual degradation across multiple frames. In order to overcome this, one scheme utilized at the decoder is...
The recently developed video compression standard, H.264/AVC surpasses the performance of previous video standards, such as MPEG-2, MPEG-4(part2), and H.263 and is therefore expected to be selected as the video standard for most digital video applications. The widely distributed infrastructure, however, continues to use the previous standards. Heterogeneous video transcoding offers a significant key...
This letter proposes a unified loop filter for video coding, which suppresses the quantization noise optimally and improves the objective and subjective qualities of the reconstructed picture simultaneously. The proposed filter unifies nonlinear enhancement filter and linear restoration filter within the classical optimization framework of least mean square error. To adapt to locally diverse quantization...
