摘要

Assistance information related to a tier framework may describe signaling for extractable and decodable sub-sequences based on pictures interdependencies. This may allow a video application to efficiently select pictures when performing a given trick mode.

1. A method comprising:
receiving a High Efficiency Video Coding (“HEVC”)-coded bitstream containing plural elementary streams of a first video program; presenting a user interface to a viewer providing options to control trick mode functionality; receiving a request for trick mode operation from a user; and interpreting assistance information contained in data fields of the bitstream to affect certain behavior to provide the requested trick mode, wherein the assistance information pertains to picture interdependencies related by successive tier numbers.
