OPTIMIZING HIGH DYNAMIC RANGE IMAGES FOR PARTICULAR DISPLAYS
To enable practical and quick generation of a family of good looking HDR gradings for various displays on which the HDR image may need to be shown, we describe color transformation apparatus (201) to calculate resultant colors (R2, G2, B2) of pixels of an output image (IM_MDR) for a display with a display peak brightness (PB_D) starting from input colors (R,G,B) of pixels of an input image (Im_in) having a maximum luma code corresponding to a first image peak brightness (PB_IM1) which is different from the display peak brightness, characterized in that the color transformation apparatus comprises: a color transformation determination unit (102) arranged to determine a color transformation (TMF; g) from color processing specification data (MET_1) comprising at least one tone mapping function (CC) for at least a range of pixel luminances received via a metadata input (116), which color transformation specifies the calculation of at least some pixel colors of an image (IM_GRAD_LXDR) having corresponding to its maximum luma code a second image peak brightness (PB_IM2), which is different from the display peak brightness (PB_D) and the first image peak brightness (PB_IM1), and whereby the division of the first image peak brightness by the second image peak brightness is either larger than 2 or smaller than ½; a scaling factor determination unit (200) arranged to determine a resultant common multiplicative factor (gt), by comprising: a capability metric determination unit (1303) arranged to determine a metric for locating positions of display peak brightnesses between the first image peak brightness (PB_IM1), and the second image peak brightness (PB_IM2) and outside that range; and a resultant multiplier determination unit (1310) arranged to determine from the display peak brightness (PB_D), the metric, and the color transformation the resultant common multiplicative factor (gt), and wherein the color transformation apparatus (201) further comprises a scaling multiplier (114) arranged to multiply a linear RGB color representation of the input colors with the resultant common multiplicative factor (gt).
ADAPTING RUNTIME AND PROVIDING CONTENT DURING AN ACTIVITY
Methods and systems are described for identifying and adapting the playback speed of content to be provided during an activity. The methods and systems receive an input including a start cue indicating a start of an activity and access an average duration and an intensity score for the activity. Then the system calculates an adjusted average runtime for the activity based on the average duration and the intensity score and identifies one or more content items, the one or more content items having a total runtime equivalent to the adjusted average runtime for the activity. The system adjusts the playback speed of the identified one or more content items such that the total runtime of playback of the one or more content items matches the average duration for the activity and provides the one or more content items for consumption.
METHODS AND SYSTEMS FOR FACILITATING PROVIDING OF AUGMENTED MEDIA CONTENT TO A VIEWER
Disclosed herein is a method for facilitating providing of augmented media content to a viewer, in accordance with some embodiments. Accordingly, the method may include receiving viewer information, analyzing the viewer information, identifying a media content, receiving the media content, analyzing the media content, identifying an interaction element in the media content, receiving a broadcaster preference and a viewer preference, receiving viewer interaction data, retrieving augmentation content, transmitting the augmentation content, generating a contextual parameter, transmitting the contextual parameter, receiving a selection of an augmentation content, embedding the augmentation content and the viewer context variable in the media content to obtain an augmented media content, transmitting the augmented media content, receiving a broadcaster context value corresponding to a broadcaster context variable, receiving a time stamp, receiving an auto-response content, and embedding the auto-response content in the media content.
Video motion augmentation
A system for providing video motion augmentation is disclosed. In particular, the system provides mechanisms for analyzing video content, metadata, or a combination thereof, to dynamically enhance and adapt regions of small movements or micro-movements in the video content based on a variety of inputs. The regions of small movements or micro-movements may be enhanced based on device characteristics associated with a device consuming the video content, based on a theme associated with the content, based on sensor data, based on user feedback, and based on a variety of other inputs. For example, motion content in the video content may be enhanced and emphasized based on the display resolution or other device characteristics of a device requesting the video content. Once the enhanced video content is generated based on the inputs, the enhanced content may be provided to the device requesting the content.
TRANSMISSION APPARATUS, TRANSMISSION METHOD, RECEPTION APPARATUS, AND RECEPTION METHOD
Both a conventional receiver and an HDR-compatible receiver well perform electro-optical conversion processing on transmission video data obtained by using an HDR opto-electronic transfer characteristic. High dynamic range opto-electronic conversion is performed on high dynamic range video data to obtain the transmission video data. Encoding processing is performed on this transmission video data to obtain a video stream. A container of a predetermined format including this video stream is transmitted. Metadata information indicating a standard dynamic range opto-electronic transfer characteristic is inserted into a layer of the video stream, and metadata information indicating a high dynamic range opto-electronic transfer characteristic is inserted into at least one of the layer of the video stream and a layer of the container.

For example, to the metafile, stream correspondence relation information indicating in which audio stream the encoded data of the plurality of groups is included respectively is further inserted.
Rendering Video Stream In Sub-Area Of Visible Display Area
A system and method for rendering a video stream for display on a display device, which may comprise receiving the video stream by streaming and generating display data defining a visible display area to be displayed by the display device, wherein said generating of the display data comprises rendering the video stream in a sub-area of the visible display area. A selection mechanism may be provided by which a version of the video stream may be selected for streaming having a spatial resolution and/or a bitrate which is selected based on a size of the sub-area. Thereby, the video stream may be adapted in terms of visual quality to the effective spatial resolution provided by the sub-area. For a smaller sub-area, it may be avoided to stream a version of the video stream which contains spatial detail which cannot be perceived when the video stream is rendered in the sub-area but which may incur more technical cost, e.g., in terms of required network bandwidth, decoding capabilities and decoding resource allocation, etc., than a video stream which has a lower resolution and/or lower bitrate and is thereby adapted to the size of the sub-area.
