Abstract: An exemplary device renders, within a field of view of an immersive virtual reality world (“world”) presented on a display screen, content of the world based on a stream of a first content file comprising a first content sector of the world. The device predicts that a user will provide user input representative of a request to shift additional content included in a second content sector of the world but not the first content sector into the field of view. Based on the prediction, the device requests and begins receiving a stream of a second content file comprising the second content sector. The device then detects the predicted user input from the user and, in response, switches from rendering the content included in the first content sector based on the first content file to rendering the additional content included in the second content sector based on the second content file.

Abstract: A method, system and computer program product for selecting a bitrate to stream encoded media. A manifest file is fetched, where the manifest file contains metadata for encoded media segments which includes tags signifying the associated encoded media segments being important to the viewer. A playback occupancy level is then increased before reaching these tagged media segment(s). A high bitrate (high quality) is selected to stream the tagged media segment(s) which are then fetched and played at the selected high bitrate in response to the new playback buffer occupancy level being above a threshold level. In this manner, those media segments that are of higher importance to the viewer will be viewed in a higher quality since content information is used to select the bitrate to receive the encoded media segments. As a result, the user's quality of experience in viewing media is improved.

Abstract: In one aspect, an example method includes: receiving an instruction to apply a first particular DVE to a temporal portion of a video segment; making a determination that no temporal portion of the video segment satisfies each condition in a condition set; and based, at least in part, on the received instruction and the determination, transmitting to a DVE system a first instruction that causes the DVE system to apply a second particular DVE to a particular temporal portion of the video segment, thereby causing first content within a region of the particular temporal portion of the video segment to be removed, and a second instruction that causes the DVE system to apply the first particular DVE to at least part of the particular temporal portion of the video segment, thereby causing second content to be overlaid within the region of at least part of the particular temporal portion.

Abstract: Systems and methods for performing bit rate encoding are described. One of the methods includes receiving data indicating a change in a first connection speed that is associated with a first network. The change generates a second connection speed. The method further includes determining whether a media file is being downloaded. The method also includes determining that a current segment of the media file is being downloaded. The current segment is downloaded at a first bit rate and the first bit rate is associated with the first connection speed. The method includes determining whether the media file includes a remaining segment to be downloaded. The current segment precedes the remaining segment. The method includes identifying a second bit rate based on the second connection speed, receiving the remaining segment at the second bit rate, and stitching the remaining segment with the current segment.

Abstract: Links are set among three hierarchical data and one moving image data. When a display area overlaps with a first link area while an image is being displayed by using first hierarchical data, switching to display by use of the 0-th hierarchical level of the second hierarchical data is made. When the display area overlaps with a second link area while an image is being displayed by using the second hierarchical data, switching to display by use of the 0-th hierarchical level of the third hierarchical data is made. The link destination of another link area is the moving image data and moving image reproduction is started as a result of zoom-up of this area. The hierarchical data are held on the client terminal side and the data existing on the other side of a switching boundary are transmitted to the client terminal in a data stream format.

Abstract: An interactive video/multimedia application (IVM application) may specify one or more media assets for playback. The IVM application may define the rendering, composition, and interactivity of one or more the assets, such as video. Video multimedia application data (IVMA data may) be used to define the behavior of the IVM application. The IVMA data may be embodied as a standalone file in a text or binary, compressed format. Alternatively, the IVMA data may be embedded within other media content. A video asset used in the IVM application may include embedded, content-aware metadata that is tightly coupled to the asset. The IVM application may reference the content-aware metadata embedded within the asset to define the rendering and composition of application display elements and user-interactivity features. The interactive video/multimedia application (defined by the video and multimedia application data) may be presented to a viewer in a player application.
