TL;DR: The in-loop deblocking filter used in the upcoming HEVC standard to reduce visible artifacts at block boundaries has lower computational complexity and better parallel processing capabilities while still achieving significant reduction of the visual artifacts.

TL;DR: The core transforms specified for the high efficiency video coding (HEVC) standard were designed as finite precision approximations to the discrete cosine transform (DCT) to allow implementation friendliness and is friendly to parallel processing.

TL;DR: Coding efficiency improvements are achieved with lower complexity than the H.264/AVC Baseline Profile, particularly suiting the proposal for high resolution, high quality applications in resource-constrained environments.

TL;DR: HEVC specifies two-dimensional transforms of various sizes from 4 × 4 to 32 × 32 that are finite precision approximations to the discrete cosine transform (DCT) and also supports frequency-dependent quantization by using quantization matrices for all transform block sizes.

TL;DR: The subjective quality of the proposal is evaluated extensively and the results show that the proposed method achieves similar visual quality as H.264/AVC High Profile anchors with around 50% and 35% bit rate reduction for low delay and random-access experiments respectively at high definition sequences.
