In intra string copy (ISC) technique for screen content coding, since the two string matching parameters, string position offset (pos) and string length (len), exhibit some unusual characteristic, directly applying the existing HEVC binarization to the one-dimentional (1-D) string matching parameters results in poor entropy coding performance. To solve this problem, in this paper, we propose a bijective...
This paper proposes a compound image compression method named United Coding (UC). In this coding method, several lossless coding techniques such as run-length encoding (RLE), Portable Network Graphics (PNG) and gzip are combined into H.264 hybrid coding, and macroblock is the basic coding unit. All coders in UC are used to code each macroblock, and rate-distortion (R-D) optimization criterion is applied...
This paper proposes a Unified LZ and Hybrid Coding (ULHC) method for compound image and video compression. The method is macroblock-based. Each macroblock is first coded simultaneously by both H.264 and gzip, then rate-distortion optimization is used to select either H.264 coding or gzip coding as the final coding of the macroblock. To improve the compression performance of ULHC, gzip uses the most...
This paper proposes a computing paradigm where many users share a host platform consisting of one or more multicore CPU(s) and GPU(s). Each user is connected to the host by a link transferring primarily compressed compound video of screen, mouse and keyboard data. All computation and processing tasks including but not limited to 2D/3D graphics and multimedia processing are done on the host using a...
