中文拼音 [sǎomiáoyāsuōbāo]
掃描壓縮包
英文
scan archives-
Also, it supports scanning in memory including the decompression of archives packed files, resulting in unrivaled scanning speed and robustness
最後，它支持內存掃描包括解壓壓縮檔打包文件，掃描速度驚人This paper first research on main technologies used by avs standard, which include prediction, transform, quantization, in - loop filter, and entropy encoding, and then focus on the 2d - vlc entropy coder of avs, which is context - based adaptive coder. this encoder operates on run - level pair, and it uses the type of current block and value of current coefficients to switch vlc code - table. these tables are designed according to the distribution of transformed coefficients, and this way is much better than using only one table to code all residual coefficients in one 8x8 block
本文首先詳細研究了avs標準的核心技術，包括預測編碼、變換量化、環路濾波器以及掃描和熵編碼等，之後重點研究了avs標準中使用的基於上下文的2d - vlc變長編碼方法，這種方法編碼的是（ run ， level ）數對，同時根據當前編碼塊的類型和殘差系數這兩種上下文信息來切換碼表，這些碼表是預先根據變換系數在不同位置的分佈信息設計好的，這樣要比只使用一個變長碼表來編碼塊內所有位置上的殘差系數的壓縮效果要好得多。
