Ali current video coding standards such as h . 263 + employ variable length codes ( vlc ) , to achieve high compression efficiency 在現在流行的視頻編碼標準中(例如h 263 + )均使用可變長編碼( vlc )來獲得高效的壓縮比。
This will be begged that the image compression technology not only have good compression efficiency but also can handle nimbly the compression code rate 這就要求圖像壓縮技術不僅要有良好的壓縮效率,而且還可以靈活處理壓縮碼率。
Through large amount of experiments , we conclude that the video compressing program can a chieve higher compression efficiency after using the improved algorithm 因此,在本文的最后,作者對視頻壓縮算法的進一步改進策略進行了研究。
Moreover , we use prediction coding process to achieve high compression efficiency , error data still cause errors to propagate in the temporal direction 而且,由于編碼器利用幀間預測來降低數據量,導致錯誤數據又會在時間域上進行擴散。
Compared with the existing header compression scheme , rfc3095 ( rohc ) has the highest compression efficiency and the best robustness and is suitable for wireless links 在現有的頭部壓縮協議中,以rfc3095 ( rohc )壓縮效率和健壯性最高,最適合于無線鏈路的使用。
