A Performance Analysis of the ITU-T Draft H.26L Video Coding Standard
نویسندگان
چکیده
The ITU-T draft H.26L video coding standard has been designed with the goal of enabling significantly improved compression performance relative to all existing video coding standards, as well as other important features, such as error resilience and network adaptability. While the basic coding framework of the standard is similar to that of currently popular video standards, H.26L includes many coding features not present in earlier standards. In this paper, we first illustrate the improved coding efficiency enabled by H.26L relative to existing video coding standards. Then, we provide a detailed analysis of the individual coding gains provided by several key features of the H.26L standard. These results can be used to motivate further improvements to the standard, assist in choosing the features that will comprise each of its profiles, and facilitate the development efficient encoding algorithms that find an optimal balance between coding performance and complexity.

The error concealment feature in the H.26L test model
This paper presents the error concealment (EC) feature implemented by the authors in the test model of the draft ITU-T video coding standard H.26L. The selected EC algorithms are based on weighted pixel value averaging for INTRA pictures and boundary-matching-based motion vector recovery for INTER pictures. The specific concealment strategy and some special methods, including handling of B-pict...
متن کاملUsing the Draft H.26l Video Coding Standard for Mobile Applications
The mai n goals of the new ITU -T H.26L standardization effort are enhanced compression performance and provision of a “network-friendly” packet -based video representation addressing “conversational” (i.e., video telephony) and “non conversational” (i.e., storage, broadcast, or streaming) applications. Hence, the H.26L design covers a Video Coding Layer (VCL), which provides the core high -com...

متن کاملGeneralized B Pictures and the Draft H.26L Video Compression Standard
This paper reviews recent advances in using B pictures in the context of the draft H.26L video compression standard. We focus on reference picture selection and linearly combined motion-compensated prediction signals. We show that bi-directional prediction exploits partially the efficiency of combined prediction signals whereas multihypothesis prediction allows a more general form of B pictures...
