EXTENSIONS OF MOTION-CONSTRAINED TILE SETS SEI MESSAGE FOR INTERACTIVITY

摘要

An extension to the motion-constrained tile sets SEI message provides functionality to signal all tiles are independently decodable and to signal the ROIs that may have more than one tile per ROI. With this extension, the functionality to redefine any independently decodable region-of-interest in a CVS at a coding tree unit level based on user interactivity is enabled. The extension supports the interactivity utilized in various applications such as interactive Ultra High Definition Television (UHDTV), dynamic high-quality zoom-in application, interactive on-demand, e-learning, smart surveillance and many other applications. Additionally, the temporal MCTS SEI message is able to be used by an encoder for tiled streaming to signal explicitly to the decoder that the decoder need only to display the ROI.

主权项

1. A method programmed in a non-transitory memory of a device comprising:
a. receiving a bitstream of a video, wherein the bitstream includes a supplemental enhancement information message, further wherein the supplemental information message signals all tiles are independently decodable and that regions of interest are able to have more than one tile per region of interest; and b. decoding the bitstream on the device.
