1、數字視頻格式及時序從Consumer產品到Broadcast產品接觸到的數字化的處理越來越多，模擬的越來越少。以前關注模擬視頻的分析測試，現在則越來越多的要應對數字視頻信號的處理。1：這里列岀一些常用的數字視頻格式及時序以做參考。NameHact/actHtot/totSTF/sHSYNC/sMSa/sHbnkVbnkHS2HA480i6072048085852529.9715734.2513.513845122576i50720576864625251562513.514449132480p60720480858525p59.9431468.52713845122576p5072057686
