This paper presents a algorithm that combined unary code and exp - golomb code. it switched separately in consideration of the difference between luma and chroma coefficients, instead of setting a marking bit which will bing loss at the same time, and also added some corresponding context models. it had been tested on sd, hd and cif, three types of sequence, and the bitrate had been saved by 1. 24134 %, 0. 10016 % and 0. 16029 % on average
針對這種情況，本文引入exp - golomb碼來減少較大的變換系數二值化的冗餘問題，提出了一種unary碼和exp - golomb碼相結合的的二進制化演算法，該演算法避免了設立標志位所帶來的附加損耗，分別針對于變換系數中的luma系數和chroma系數的概率分佈特點，採取了不同的自適應切換設置，並且相應地增加了概率模型。 -
Exp - golomb codes are applied to code the pairs of the run - length of zero coefficients and the nonzero coefficient for lower storage requirement. c2dvlc is a low complexity coder in terms of both computational time and memory requirement
以往視頻編碼標準如h . 263定義了可選擇的算術編碼器，新近的h . 264 avc標準也採用了高效的算術編碼方法cabac 。 -
The unary code is applied in the binarization of the translation coefficients in the national standard avs. it is preponderant for the small values, but will bring more redundancy for the bigger ones. so the exp - golomb code is introduced for the redundancy reduction
在avs標準中，變換系數level值的二值化方案採用了unary碼， unary碼對較小的整數值二值化效果較好，但對較大的值則會造成很大的冗餘，從而影響了cabac的編碼效率。 -
Therefore, the main subject of this paper is to design a universal, low complexity, lossless and near - lossless compression algorithm for biomedical signals, fith a series of techniques, including context modeling, adaptive prediction and golomb coding, our algorithm obtains satisfactory results on various kinds of biomedical signals with low complexity of implementation
從上述考慮出發，本課題研究設計了一個通用、低復雜性的生物醫學信號無損近無損壓縮演算法。通過採用上下文建模、自適應預測和golomb編碼等一系列技術，該壓縮演算法對各類生物醫學信號都獲得了較好的壓縮效果，達到了通用、低復雜性的設計要求。 -
For the exponential - golomb code is a kind of prefix - codes, and the fact that using prefix - code means there are some strings that cannot be used any more. moreover, it may have some redundancies in it. therefore, we introduce a new algorithm that can remove these redundancies in this paper
由於2d - vlc中使用的指數哥倫布碼是一種前綴碼，而使用前綴碼本身就意味已經有一部分的0 / 1串不能被使用，從而產生冗餘，所以本文研究了一種可以消除這種碼字構造冗餘的演算法，即基於前綴碼的視頻熵編碼演算法（ pcbe ） ，對其給予了完整的數學描述，證明了這種演算法應用於avs標準中的可行性。
