2在同樣的視頻質量下，壓縮演算法的輸出碼率直接決定其性能的優劣，或者說，輸出碼率相同的條件下，圖象質量的優劣反映了壓縮演算法的性能。由於m - jpeg和dv都是採用幀內壓縮方式，它們的壓縮效率當然要比mpeg2低。當然，這是一個平均情況，在低碼率的時候， mpeg2可以比m - jpeg的壓縮比高很多而保持較好的圖像質量而在要求圖像質量很好的時候比如演播室節目編輯和後期製作，它們的差別不是很大。The development of mechanized mathematics goes through tortuous way in the western countries, written calculation is the most compute means. the mechanized degree of writing calculation is lower, and not meet the actual demands. other means, example : table calculation, slide rule, graphic solution, are invented to make up the defect of writing calculation
