By introduce new video coding technologies , avs and h . 264 gain a wonderful coding efficiency . the computing complexity also increases for 2 - 3 times than mpeg - 2 because of the complexity of the algorithm . that means the performance of software decoding can not achieve a high level , especially the real - time high - definition decoding
同時avs和h . 264等高級視頻編碼標準采用了大量最新的視頻編碼技術(shù),獲得了很好的效果,但是其壓縮效率的提高也是以壓縮算法復(fù)雜度的提高為代價的,其解碼復(fù)雜度大約是mpeg - 2的2 - 3倍,這造成了單純用軟件解碼難以達到很高的性能,特別是對于實時應(yīng)用,對于高清晰度視頻不能實現(xiàn)實時解碼,這樣就需要硬件加速或者設(shè)計專門的硬件解碼電路。

Avs1 - p2視頻壓縮標準的制定開始于2002年6月，它主要面向標清和高清視頻的編碼，目標是要取得與h . 264 avc相似的編碼性能，而編碼復(fù)雜性要大大低于h . 264 avc 。

As to still image coding , even though the performance of wavelet image coding algorithms excel first generation image compression standard jpeg , but they will produce boring mosquito noise at low bit - rates , which are mainly located around image edges . besides that , their coding efficiency will drop rapidly for those natural images with rich textures
而在靜態(tài)圖像編碼方面，雖然小波圖像算法的編碼性能遠遠超過第一代圖像壓縮標準jpeg ，但它在低位率條件下也會出現(xiàn)蚊式噪音，主要集中在圖像邊緣附近，而且對于包含豐富紋理的自然圖像，其編碼效率也會急劇下降。

Ii sqs image coding has achieved higher coding efficiency , but he hasn ? thought about the differences between relativity degree and feature of the wavelet subtrees in different directions , according to the differences of the relativity among them , different scan methods have been adopted in coding
Sqs算法的核心是利用不同方向、不同頻帶之間的小波系數(shù)的自相關(guān)性進行分形編碼。盡管davis的sqs算法取得了較高的編碼效率，但他沒有考慮到位于不同方向上的小波樹之間的相關(guān)性程度和性質(zhì)是不一樣的。
It imposes some bad impact on video implement over network and imposes many challenges to the traditional nonscalable video coding technology which is not efficient for transmission video over the error - prone . then the scalable video coding technology was proposed , which can provide a rang of bitrate change and its redundant video content compensate the transmission error , but loss coding efficiency
傳統(tǒng)的不可分級編碼技術(shù)已經(jīng)不能滿足視頻在這類網(wǎng)絡(luò)上的傳輸需要，就提出了可分級編碼技術(shù)，它能提供一定的位率可變范圍，同時因可分級性而帶來的冗余信息也在一定程度上補償了因傳輸誤差而引起的視頻內(nèi)容的損失，但也因此而損失了編碼效率。
Firstly , based on conventional vq , a fast algorithm named equal - sum block - extending nearest neighbor search ( ebnns ) is presented , which not only can achieve the reconstructed image of full search algorithm but also can greatly reduce both the codeword search ratio and chip area . in order to improve coding efficiency , a new algorithm called correlation - inheritance coding is proposed , which is embedded in conventional vq system to improve compression ratio by re - encoding the indexes
