Method and apparatus for temporal motion vector prediction

A video decoder for video decoding, comprising:

• processing circuitry configured to:
• acquire a current picture from a coded video bitstream,
• select a previously decoded first neighboring block from a plurality of previously decoded neighboring blocks of a current block in the current picture,
• determine, based on a motion vector of the selected previously decoded first neighboring block, a candidate block that is included in a previously decoded picture and that is one of (i) neighboring to a collocated block of the current block and (ii) within the collocated block, and
• perform temporal motion vector prediction for the current block based on a motion vector of the candidate block.

A non-transitory computer readable medium having instructions stored therein, which when executed by a processor in a video decoder causes the processor to execute a method comprising:

• acquiring a current picture from a coded video bitstream;
• selecting a previously decoded first neighboring block from a plurality of previously decoded neighboring blocks of a current block in the current picture;
• determining, based on a motion vector of the selected previously decoded first neighboring block, a candidate block that is included in a previously decoded picture and that is one of (i) neighboring to a collocated block of the current block and (ii) within the collocated block;
• and
• performing temporal motion vector prediction for the current block based on a motion vector of the candidate block.
