摘要
Apparatuses and methods for optimizing rate-distortion costs of a signal are disclosed. An apparatus may include an encoder. The encoder may be configured to receive a video signal and provide a residual indicative of a difference between the video signal and a reconstructed video signal. The encoder may further be configured to perform a transform on the residual to provide a plurality of transform coefficients and rate-distortion optimize the plurality of transform coefficients in accordance with an HEVC state transition scheme to provide a rate-distortion optimized plurality of quantized coefficients. The encoder may further be configured to encode the plurality of quantized coefficients in accordance with context-adaptive binary arithmetic coding.
