Abstract: Methods, systems and architectures for video and/or audio processing and distribution are described. More particularly, a just in time transcoder/transcoding (JITT) is employed. If a matching optimal asset segment with calculated optimal asset attributes requested by a client device is not stored in a server, the server is configured to invoke the just in time transcoder (JITT) to produce the matching optimal asset segment by transcoding from one or more assets stored in an asset storage device to fulfill the request of client device.

Abstract: Systems and methods are described for providing viewers of streamed video content with the option to view alternative video content in which alternative tone maps are applied to respective regions of interest. In some embodiments, the streamed video content is divided into slices, and alternative tone maps are applied to respective regions of interest within the slices. When a server receives a request from a client for alternative tone mappings of different regions, slices with the appropriate mapping may be assembled on demand and delivered to the client in a single video stream. Tone mappings may be used, for example, to highlight particular objects, such as players in a sporting event captured in the streamed video content.

Abstract: Systems and methods are described for enabling a consumer of streaming video to obtain different views of the video, such as zoomed views of one or more objects of interest. In an exemplary embodiment, a client device receives an original video stream along with data identifying objects of interest and their spatial locations within the original video. In one embodiment, in response to user selection of an object of interest, the client device switches to display of a cropped and scaled version of the original video to present a zoomed video of the object of interest. The zoomed video tracks the selected object even as the position of the selected object changes with respect to the original video. In some embodiments, the object of interest and the appropriate zoom factor are both selected with a single expanding-pinch gesture on a touch screen.

Abstract: Systems and methods are described for providing viewers of adaptive bit rate (ABR) streaming video with the option to view alternative streams in which an alternative tone mapping is applied to one or more regions of interest. The availability of streams with alternative tone mappings may be identified in a media presentation description (MPD) in an MPEG-DASH system. In some embodiments, the streaming video is divided into slices, and alternative tone mappings are applied to regions of interest within the slices. When a server receives a request from a client device for alternative tone mappings of different regions, slices with the appropriate mapping may be assembled on demand and delivered to the requestor as a single video stream. Tone mappings may be used, for example, to highlight particular players in a sporting event.

Abstract: Systems and methods are described for enabling a client device to request video streams with different bit depth remappings for different viewing conditions. In an embodiment, information indicating the availability of additional remapped profiles is sent in a manifest file. Alternative bit-depth remappings may be optimized for different regions of interest in the image or video content, or for different viewing conditions, such as different display technologies and different ambient illumination. Some embodiments based on the DASH protocol perform multiple depth mappings at the encoder and also perform ABR-encoding for distribution. The manifest file contains information indicating additional remapping profiles. The remapping profiles are associated with different transformation functions used to convert from a higher bit-depth to a lower bit-depth.

Abstract: A method for inserting a logo into a stereo video image to generate an overlaid stereo image, the method comprising: detecting presence of stereo pictures in the video image and, when stereo pictures are detected, determining the 3D format of said stereo pictures, said 3D format being a stereo spatially multiplexed format; generating a stereo logo comprising stereo spatially multiplexed logo pictures including a representation of the logo, said stereo spatitally multiplexed logo pictures being arranged in said 3D format; and combining the stereo logo and the video image to generate the overlaid stereo image in said 3D format.

Abstract: Systems and methods are described for providing clear areas related to objects of interest in a video display. In accordance with an embodiment, a method includes capturing, with a camera, a video frame of a scene; determining a camera orientation and camera location of the camera capturing the video; determining a location of an object of interest; mapping the location of the object of interest to a location on the video frame; determining an object-of-interest area based on the location of the object of interest on the video frame; determining a clear area on the video frame; transmitting a location of the clear area to a client device; and displaying the video frame and metadata associated with the object of interest in the clear area.

Abstract: Described embodiments relate to systems and methods for displaying information regarding tracked objects and receiving user input selecting the object(s) to be tracked. One embodiment takes the form of a method that includes: receiving, from a content server, a first representation of a video stream and an object-of-information identifier that indicates availability of a second representation of a portion of the video stream that depicts an object of interest; causing the display of both the first representation of the video stream and the object-of-interest identifier; responsive to a selection of the second representation of the portion of the video stream using the object-of-interest identifier, transmitting, to the content server, a request for the second representation of the portion of the video stream; and receiving and causing display of the second representation of the portion of the video stream.

Abstract: An implementation exits a power saving mode for fixed and periodic active periods of time to receive a separate burst transmission from a first stream during each of the corresponding active periods of time. The first stream is received at a first-stream burst data rate. The first stream includes data configured to be displayed at a first playback rate that is substantially less than the first-stream burst data rate. During the active periods of time, data is received from a second stream at a second-stream rate. The second stream includes data configured to be displayed at a second playback rate that is substantially the same as the second-stream rate. After receiving each of the burst transmissions from the first stream during the active periods of time, the power saving mode is entered for corresponding fixed and periodic power-saving periods of time while waiting for another burst from the first stream.
