Coding method and apparatus with candidate motion vectors
A transmitting method for transmitting a bitstream to a terminal is provided. The bit stream is generated by coding a current block of a picture and has an index for identifying a motion vector candidate from a motion vector candidate list. The motion vector candidate list is generated and includes motion vector candidates and a value for each motion vector candidate. A second candidate is arranged before a first candidate in the motion vector candidate list. The first candidate is sorted before the second candidate in the motion vector candidate list based on the values of the first and second candidates. The value of the first candidate is higher than the value of the second candidate. For each motion vector candidate, the value is based on a number of times the motion vector candidate is selected as a motion vector predictor for neighboring blocks.
1. A transmitting method for transmitting a bitstream to a terminal, the bit stream being generated by coding a current block of a picture and the bitstream having an index for identifying a motion vector candidate from a motion vector candidate list, the motion vector candidate list being generated by performing processes, the processes including:
generating the motion vector candidate list including motion vector candidates and a value for each of the motion vector candidates, the motion vector candidates including a first candidate and a second candidate, the second candidate being arranged before the first candidate in the motion vector candidate list; and
sorting the first candidate before the second candidate in the motion vector candidate list based on the value of the first candidate and the value of the second candidate,
wherein the value of the first candidate is higher than the value of the second candidate, and
for each motion vector candidate of the motion vector candidates, the value is based on a number of times the motion vector candidate is selected as a motion vector predictor for neighboring blocks.
