  1. Context - based 2d - vlc entropy coder in avs video coding standard

    基於上下文的二維變長熵編碼器
  2. Coding of audio - visual objects - part 2 : visual. iso iec 14496 - 2 mpeg - 4 visual version 1, 1999. 9 lakhani g. optimal huffman coding of dct blocks

    Cavlc熵編碼器採用上下文技術挖掘塊內系數的相關性,獲得了較高的效率,但其設計來源於對4x4塊進行
  3. Joint video team of iso iec jtc1 sc29 wg11 itu - t sg16 q. 6 doc., klagenfurt, austria, july 2002, jvt - d034. 12 final draft of information technology - advanced coding of audio and video - part 2 : video

    本文的基於上下文的變長方法c2dvlc獲得了更高的效率,相比于mpeg - 2的2d - vlc熵編碼器,在一些典型的高清標清測試序列上,效率平均提高0 . 34db ,與h . 264的cavlc相比,效率相當。
  4. This paper also present a method that reduces the computational requirements of the encoder, while still upholding picture fidelity and remaining compatible with the h. 263 bitstream standard. often a substantial number of inter - macroblocks in the encoder are reduced to all - zero values after quantization. we introduced a method of predicting when those macrobolcks will quantize to zeros, which in turn allows us to eliminate the computation that would normally be required for those macroblocks

    中宏塊經過dct變換和量化后,總有一定數量的宏塊的系數全為零,因此在進行dct轉換前先進行預測,將那些預測系數全為零的宏塊提前查找出來,然後將系數全為零的宏塊azq ( all - zeroquantizedcoefficients )直接送到模塊進行可變長
  5. The standard is designed to give a new technical solution for a broad range of applications, such as very low bit rate conversational services and entertainment quality broadcast, interactive video - on - demand services etc. for the enhancement of the coding efficiencies, the new standard adopts new tools as following : multiple reference pictures, variable block - size with seven block sizes in motion prediction, quarter - pixel accuracy for motion vector, short word - length integer transform, context - adaptive entropy coding and loop filter deblocking

    H . 264 / avc標準支持從低帶寬、高誤率的無線移動視頻通信到高帶寬、低誤率的有線視頻廣播等多種應用,因此,日益受到業界的關注。為了實現更高的效率, h . 264 / avc標準採用了很多新的技術,如多參考幀預測、多尺寸塊模式、 1 / 4像素精度運動矢量、整數變換量化、基於內容的、新型幀內預測、去除方塊效應的濾波等。
  6. 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、變換量化、環路濾波以及掃描和等,之後重點研究了avs標準中使用的基於上下文的2d - vlc變長方法,這種方法的是( run , level )數對,同時根據當前塊的類型和殘差系數這兩種上下文信息來切換表,這些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表來塊內所有位置上的殘差系數的壓縮效果要好得多。
