Abstract
An exemplary decoding method of an input video bitstream including a first bitstream and a second bitstream includes: decoding a first picture in the first bitstream; after a required decoded data derived from decoding the first picture is ready for a first decoding operation of a second picture in the first bitstream, performing the first decoding operation; and after a required decoded data derived from decoding the first picture is ready for a second decoding operation of a picture in the second bitstream, performing the second decoding operation, wherein a time period of decoding the second picture in the first bitstream and a time period of decoding the picture in the second bitstream are overlapped in time.
