—This paper provides a performance analysis of the Scalable Video Coding (SVC) extension of H.264/AVC. A short overview presenting the main functionalities of SVC is given and main issues in encoder control and bit stream extraction are outlined. Some aspects of rate-distortion optimization in the context of SVC are discussed and strategies for derivation(More)
—A concept for variable block-size transform coding is presented. It is called adaptive block-size transforms (ABT) and was proposed for coding of high resolution and interlaced video in the emerging video coding standard H.264/AVC. The basic idea of inter ABT is to align the block size used for transform coding of the prediction error to the block size(More)
In this paper, a decoder side motion vector derivation scheme for inter frame video coding is proposed. Using a template matching algorithm, motion information is derived at the decoder instead of explicitly coding the information into the bitstream. Based on Lagrangian rate-distortion optimisation, the encoder locally signals whether motion derivation or(More)
Efficient intra prediction is an important aspect of video coding with high compression efficiency. H.264/AVC applies directional prediction from neighboring pixels on an adjustable block size for local decorrelation. In this paper, we present an extended prediction scheme in the context of H.264/AVC that comprises two additional prediction methods(More)
This contribution presents results of the MPEG verification test that was carried out for the new Scalable Video Coding (SVC) Amendment of H.264/AVC. The test consisted of a series of subjective comparisons of SVC and single layer H.264/AVC coding for different application scenarios including conversational applications, broadcasting over mobile channels,(More)
Decoder-side motion vector derivation (DMVD) using template matching has been shown to improve coding efficiency of H.264/AVC based video coding. Instead of explicitly coding motion vectors into the bitstream, the decoder performs motion estimation in order to derive the motion vector used for motion compensated prediction. In previous works, DMVD was(More)
