Abstract: Systems and methods for identifying certain objects within 360-degree content for user interaction. Objects within 360-degree content may be identified, and the corresponding segments of 360-degree content may be assigned a score according to how likely they may be to meet certain criteria, such as the likelihood that the user may interact with the object or its segment. Scores may be assigned in any manner, such as with reference to retrieved user information. In highly scored segments, users may be encouraged to pause the content at that segment, and interact with its objects. Encouragement may take any form, such as highlighting the segment or some component thereof. Likewise, interaction may also take any form, such as the allowing the user to alter the appearance of one or more segment objects in some way. In this manner, increased user interaction with 360-degree video is allowed, increasing viewer interest and engagement.

Abstract: A content selector switch selects, based on a received request for content from a particular remote control device, a multicast network on which to provide the requested particular content. Each multicast network channel of the plurality of multicast network channels is mapped to a respective video channel and each remote control device in the facility (e.g., hotel) is mapped to a respective video channel that the TV controlled by the remote control device stays tuned to. The content selector switch performs the selection by identifying which remote control device in the facility sent the request and selecting the multicast network channel that is mapped to the RF video channel the identified remote control device is mapped to. The content selector switch then provides the specific content on the selected multicast network channel to a multicast-to-channel output device that provides the content on the RF video channel for the TV tuned to that RF video channel to display.

Abstract: Systems and methods for rewinding a video to a point before the video was first viewed. Video transmitted by a media source is cached by a remote server. Upon a trick-play request for the video, the server generates a rewind stream that includes the video that was transmitted by the media source before the user started to view the video. Upon receiving the rewind stream, the user's equipment may cache the rewind stream in a rewind buffer and rewind or play from the rewind buffer. The server may also generate and transmit a forward stream of the video that the media source has not yet transmitted. The user's equipment may cache the forward stream in a forward buffer. To perform trick-play operations with the video, the user's equipment may migrate the playback of the video to the rewind and forward buffers and rewind or fast-forward the video from the buffers.

Abstract: A method includes that a media asset server receives an identifier and a new-language file of a target video and converts the new-language file into a new-language medium file. The media asset server finds a first index file based on the identifier of the target video, and obtains a second index file based on a storage address of the new-language medium file on the media asset server. The media asset server sends the new-language medium file and the second index file to a content delivery server. The content delivery server replaces the storage address of the new-language medium file on the media asset server in the second index file with a storage address of the new-language medium file on the content delivery server to obtain a third index file. The content delivery server generates a first URL of the target video.

Abstract: Methods and apparatus for providing delivery of content to client devices of a network via both multicast and unicast mechanisms. In one embodiment, a system for use in a managed content delivery network is described to bridge multicast to unicast, so that the total network bandwidth consumption is significantly lower than a corresponding unicast-only delivery solution, yet which still provides improved quality of service and user viewing experience as compared to a multicast-only delivery solution. In addition, various exemplary aspects of the present disclosure are readily adapted for real-time multicast to unicast streaming of audio and data to, among other things, minimize network bandwidth usage, while maintaining the guaranteed delivery of unicast streams with little or no modification to the existing client device logic.
