Decoding method and decoding apparatus for using parallel processing scheme to decode pictures in different bitstreams after required decoded data derived from decoding preceding picture(s) is ready

A decoding apparatus of an input video bitstream including a first bitstream and a second bitstream, each of the first bitstream and the second bitstream containing a plurality of pictures, the decoding apparatus comprising:

• an input storage, for storing the input video bitstream;
• an output storage, for storing a decoded result of the input video bitstream;
• and
• a decoding circuit, coupled between the input storage and the output storage, for decoding a first picture in the first bitstream;
• performing a first decoding operation of a second picture in the first bitstream after a required decoded data derived from decoding the first picture is ready for the first decoding operation;
• and performing a second decoding operation of a picture in the second bitstream after a required decoded data derived from decoding the first picture is ready for the second decoding operation, wherein the first bitstream contains pictures of a first view for a three-dimensional (3D) video presentation, the second bitstream contains pictures of a second view for the 3D video presentation, and 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.
