Claim 0:
1. A method of bidirectional inter prediction encoding, comprising:
determining a first motion vector difference of a current picture block and a first identifier, wherein when a value of the first identifier is a first preset value, the first identifier is used to indicate that a second motion vector difference of the current picture block is determined based on the first motion vector difference, wherein the first motion vector difference belongs to motion information of the current picture block in a first direction, and the second motion vector difference belongs to motion information of the current picture block in a second direction;
determining prediction samples of the current picture block based on the first motion vector difference and the second motion vector difference;
encoding the first identifier and the first motion vector difference into a bitstream.
