An iterative method for hypothetical reference decoder [video coding]
We propose a simple iterative method to verify whether a coded bitstream conforms to a hypothetical reference decoder (HRD). A concept of maximum tolerated delay (MTD) is introduced to study the possible low-delay operation, such that we can bound the degree of incorrect motion rendition caused by the variation in end to end delay in the neighborhood of big pictures. Our method can be used in the design of a rate control algorithm to improve the possibility of a coded bitstream that conforms to the HRD.
