Abstract:
1. A method for rate estimation in a video encoder in a circuit, said method comprising: determining a correlation between a first rate control metric and a second rate control metric in said circuit; generating an estimation metric; and estimating the first rate control metric from the second rate control metric and the estimation metric; wherein determining, generating, and estimating occur while predicting a partition of a picture from an original another picture, wherein predicting is limited to integer offsets; executing a first plurality of instructions stored in a non-transitory computer-readable medium for predicting the partition from the another picture, wherein predicting further comprises interpolating fractional sample resolutions, thereby resulting in a prediction error; and executing a second plurality of instructions stored in a non-transitory computer-readable medium for quantizing the prediction error based at least in part on the first rate control metric.
