|20150256832||APPARATUSES AND METHODS FOR PERFORMING VIDEO QUANTIZATION RATE DISTORTION CALCULATIONS - Examples of methods and apparatuses for performing video quantization rate distortion calculations are described herein. An example apparatus may include an encoder configured to encode a macroblock of a frame. The encoder including a rate-distortion (RD) calculator configured to individually quantize a set of coefficient blocks using each of a subset of a plurality of quantization parameter (QP) values to provide individual sets of quantized coefficient blocks. Each of the individual sets of coefficient blocks is based on data of the macroblock. The RD calculator is further configured to determine individual accumulated rate and accumulated distortion value pairs for each of the plurality of QP values based on the individual sets of quantized coefficient blocks. The RD calculator further including a mode decision block configured to receive the individual accumulated rate and accumulated distortion value pairs and to generate a RD cost-QP curve based on the individual accumulated rate and accumulated distortion value pairs. The mode decision block further configured to select a QP value during encoding of the macroblock based on the RD cost-QP curve.||09-10-2015|
