Abstract:
A method for enhancing a region of interest in video frames of a video stream is described. The method includes receiving media data defining base video frames of at least one base stream, said base stream being associated with one or more enhancement tile streams, an enhancement tile stream comprising media data defining tiled video frames comprising a tile, said tile comprising media data for enhancing visual content in a subregion of the image region of the base video frames; requesting media data of one or more enhancement tile streams, preferably one or more HEVC enhancement tile streams, the one or more enhancement tile streams being associated with media data for enhancing visual content in the at least one region of interest; generating base video frames on the basis of media data of the at least one base stream and generating tiled video frames on the basis of media data of the one or more enhancement tile streams, the tiled video frames comprising one or more tiles forming visual content the at least one region of interest; and, replacing or blending at least part of the visual content of said at least one region of interest in the video frames of said base stream with at least part of said enhanced visual content of the tiled video frames.

Claim (Index 1):
Method for enhancing at least one region of interest in video frames of a video stream, preferably by a media device comprising a client device, a first decoder, a second decoder and a rendering device, the method comprising:\n a client device receiving media data defining base video frames of at least one base stream, said base stream being associated with one or more enhancement tile streams, wherein an enhancement tile stream comprises media data defining tiled video frames, a tiled video frame comprising a tile associated with media data for enhancing visual content in a subregion of an image region of a base video frame, wherein media data of an enhancement tile stream are independently decodable from the media data of said base stream; the client device requesting media data of one or more enhancement tile streams, preferably one or more HEVC enhancement tile streams, the one or more tiles of the tiled video frames of the requested media data being associated with at least one predetermined region of interest in the image region of the base video frames; a first decoder connected to said client device generating base video frames on the basis of the media data of the at least one base stream and a second decoder connected to the client device generating tiled video frames on the basis of the media data of the one or more enhancement tile streams, the generated tiled video frames comprising one or more tiles forming enhanced visual content in the at least one region of interest; and, a rendering device forming video frames comprising an enhanced region of interest by modifying at least part of the visual content of the at least one region of interest in the video frames of said base stream on the basis of at least part of the enhanced visual content of the tiled video frames, said modifying comprising replacing or blending at least part of the visual content of the at least one region of interest in the video frames of said base stream with at least part of the enhanced visual content of the tiled video frames.
