摘要： A system and method for dynamically setting a complexity level for a scalable module in a video decoder. The method comprises the steps of: decoding a first GOP using an initial threshold value; determining an adjusted threshold value for the first GOP; and decoding a second GOP using the adjusted threshold value calculated for the first GOP. A calculation system is similarly disclosed that determines a threshold value for a current GOP based on a previously decoded GOP by iteratively selecting different threshold values until a scaled complexity of the decoder system for a previous GOP substantially meets a required complexity of the video decoder system for the current GOP.
