VVC Search Space Analysis Including an Open, Optimized Implementation

چکیده
Versatile Video Coding (VVC) is a new video coding standard finalized in July 2020. During the development much attention was paid to keeping decoding complexity increase as small possible, with more permissive approach being taken regard encoding. The VVC reference software VTM random access configuration requires around double time decode and $8\times $ encode video, compared High Efficiency (HEVC) HM. With this runtime increase, an objective bitrate reduction of 40% achieved. In paper we analyze encoding over HEVC. We abstract implementation-based aspects, including low-level optimizations introduce empirical measure quantify extent encoder search space given specific algorithm. Based on measure, compare HM VTM, but also open optimized implementation VVenC, showing potential for its impact compression performance. Overall, it can be seen that while VVC’s quite large efficiently limited either by early termination strategies or disabling tools.

Moreover to this user’s location were used to provide location conce...
متن کاملAnalysis of an Optimized Search Algorithm for Skip Lists
It was suggested in Pugh (1990) to avoid redundant key comparisons in the skip list search algorithm by marking those elements whose key has already been compared against the search key. We present here a precise analysis of the total search cost (expectation and variance), where the cost of the search is measured in terms of the number of key-to-key comparisons. These results are then compared...
