Abstract:
This disclosure describes techniques for rate control for intra coded frames. In one example of the disclosure, a rate control parameter may be calculated using a target bit rate and a complexity measure. In one example, the complexity measure is calculated with a sum of absolute transformed differences (SATD) calculation of an intra-coded frame.
