Encoder and encoding method using coded block pattern estimation

摘要

An encoder includes a motion estimation module configured to perform motion estimation of a current frame based on at least one reference frame, a motion compensation module configured to generate a signal including a compensation image for the current frame from the at least one reference frame using a result of the motion estimation performed by the motion estimation module, and a coded block pattern (CBP) estimation module configured to estimate a CBP based on the signal output from the motion compensation module.

1. An encoder comprising:
a motion estimation module configured to perform motion estimation of a current frame based on at least one reference frame; a motion compensation module configured to generate a signal including a compensation image for the current frame from the at least one reference frame using a result of the motion estimation performed by the motion estimation module; and a coded block pattern (CBP) estimation module configured to estimate a CBP based on the signal output from the motion compensation module, wherein the signal output from the motion compensation module comprises a motion vector value from a current macroblock and a motion vector estimation value estimated from a macroblock adjacent the current macroblock wherein the CBP estimation module comprises: a transform unit configured to transform a difference between the motion vector value and the motion vector estimation value; and a quantization unit configured to quantize an output signal of the transform unit.
