摘要： A method of operating a video decoder system includes decoding an encoded video frame using a decoder control unit for determining whether the acceleration is required for respective decoding functional units and the degree thereof. This includes the decoder control unit receiving a target time value to be taken to decode a frame; the decoder control unit performing main processing including inverse transformation and motion prediction on a predetermined frame; the deblock unit providing a value of time taken to perform deblock filtering on a frame prior to the predetermined frame to the decoder control unit; the decoder control unit comparing a value of total time taken with the target time value, in which the received value of time taken for the deblock filtering of the previous frame and the value of time taken for the main processing are added; and the decoder control unit accelerating deblock filtering of the deblock unit if it is determined that the total time taken exceeds the target time value at the comparison step.
