Abstract
An image decoder has circuitry coupled to a memory. The circuitry splits a current image block into a plurality of partitions. The circuitry predicts a first motion vector from a set of uni-prediction motion vector candidates for a first partition of the plurality of partitions, and decodes the first partition using the first motion vector.
Claims29
An image decoder comprising:
- circuitry;
- and
- a memory coupled to the circuitry;
- wherein the circuitry, in operation:
- splits a current image block into a plurality of partitions;
- predicts a first motion vector from a set of uni-prediction motion vector candidates for a first partition of the plurality of partitions;
- and
- decodes the first partition using the first motion vector.

An image decoder comprising:
- an entropy decoder which, in operation, receives and decodes an encoded bitstream to obtain quantized transform coefficients,
- an inverse quantizer and transformer which, in operation, inverse quantizes the quantized transform coefficients to obtain transform coefficients and inverse transform the transform coefficients to obtain residuals,
- an adder which, in operation, adds the residuals outputted from the inverse quantizer and transformer and predictions outputted from a prediction controller to reconstruct blocks, and
- the prediction controller coupled to an inter predictor, an intra predictor, and a memory, wherein the inter predictor, in operation, generates a prediction of a current block based on a reference block in a decoded reference picture and the intra predictor, in operation, generates a prediction of a current block based on an encoded reference block in a current picture, wherein the inter predictor, in operation,
- splits a current image block into a plurality of partitions;
- predicts a first motion vector from a set of uni-prediction motion vector candidates for a first partition of the plurality of partitions;
- and
- decodes the first partition using the first motion vector.
