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.

A method, comprising:
The method of claim 1 wherein all tiles in a base layer of the video are independently decodable.
The method of claim 1 wherein all tiles in an enhancement layer of the video are independently decodable.
The method of claim 1 wherein a region of interest of the video is selected by a user, wherein the region of interest selected by the user is presented on the device.
The method of claim 1 wherein a region of interest of the video is selected by a user, wherein the region of interest selected by the user is presented on a second device.
The method of claim 1 wherein a region of interest of the video is selected by a director, wherein the region of interest selected by the director is presented on the device of a user, wherein the director is a user who controls the video and/or is able to modify the video.
The method of claim 1 wherein the video is encoded with independently decodable tiles and in one or more resolution layers and stored on a server.
The method of claim 1 wherein different users request different resolution layers of the video.
The method of claim 1 wherein different directors request different resolution layers of the video.
The method of claim 1 wherein the supplemental enhancement information message indicates coding tree blocks outside a selected region of interest, wherein the coding tree blocks outside the selected region of interest are not displayed.
The method of claim 1 wherein the supplemental enhancement information message indicates coding tree blocks outside a selected region of interest, wherein the coding tree blocks outside the selected region of interest are encoded as tiles that are able to be encoded efficiently to reduce bitrate.
