PARALLEL PROCESSING FOR VIDEO CODING

摘要

In one example, a device for coding video data includes a video coder configured to code data indicating whether tile boundaries of different layers of video data are aligned and whether inter-layer prediction is allowed along or across tile boundaries of enhancement layer blocks, code an enhancement layer block in an enhancement layer tile of the video data without using inter-layer prediction from a collocated base layer block for which inter-layer filtering or reference layer filtering across tile boundaries in a reference layer picture in an access unit including both the enhancement layer tile and the base layer block is enabled, and code the collocated base layer block.

1. A method of decoding video data, the method comprising:
decoding data indicating whether tile boundaries of different layers of video data are aligned and whether inter-layer prediction is allowed along or across tile boundaries of enhancement layer blocks; decoding an enhancement layer block in an enhancement layer tile of the video data, wherein when the data indicates that tile boundaries of different layers are aligned and that inter-layer prediction is allowed, decoding the enhancement layer block comprises decoding the enhancement layer block without using inter-layer prediction from a collocated base layer block for which inter-layer filtering or reference layer filtering across tile boundaries in a reference layer picture in an access unit including both the enhancement layer tile and the base layer block is enabled; and decoding the collocated base layer block.
