Beschreibung
Zusammenfassung:	The invention relates to frame forecast mode selecting method of H.264 criterion, the mode selecting method includes: a. input frame image; b. select 16X16 forecast mode; step b includes: b1. Forecast current macro block of frame image as 16X16 forecast mode; b2. Calculate the residual absolute value and SAD16 in 16X16 forecast mode, and collate; b3. if the least residual absolute value and SAD16MIN in 16X16 forecast mode are less than TH16_1, the forecast mode of least residual absolute value and SAD16MIN is the best forecast mode of current macro block and mode selecting of current macro block is ended. By adopting said method, based on relationship between the best forecast mode and sum of residual absolute value, combining the forecast mode selecting and interruption strategy can decrease calculation complexity of frame forecast mode selecting.
