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 12):
Method according to  claim 1 wherein said one or more enhancement tile streams are formatted on the basis of a data container of a media streaming protocol or media transport protocol, an (HTTP) adaptive streaming protocol or a transport protocol for packetized media data, such as the RTP protocol; and/or, wherein media data of the one or more enhancement tile streams are encoded on the basis of a codec supporting tiled video frames, preferably said codec being selected from one of: HEVC, VP9, AVC or a codec derived from or based on one of these codecs; and/or, wherein media data of the one or more enhancement tile streams defined by the one or more enhancement tile stream identifiers are stored in (tile) tracks and wherein metadata associated with at least part of the one or more enhancement tile streams are stored in at least one base track, preferably said tile tracks and at least one base track having a data container format based on ISO/IEC 14496-12 ISO Base Media File Format (ISOBMFF) or ISO/IEC 14496-15 Carriage of NAL unit structured video in the ISO Base Media File Format.
