A companion device interoperating with a broadcast reception device for receiving a broadcast signal, can include a communication device configured to connect the companion device with the broadcast reception device, in which the broadcast signal includes emergency alert information and service information for a broadcast service, and the service information includes service identification information for identifying the broadcast service and name information of the broadcast service, and the emergency alert information and the service information are carried in Internet Protocol (IP) packets having a same IP address; and a controller configured to receive the emergency alert information from the broadcast reception device, the emergency alert information including identifier information for the emergency alert information, category information of the emergency alert information, and priority information for the emergency alert information, and the controller receiving information for components of the broadcast service.

A user interface allows for blending of television program choices from which a viewer may select, the blending representing options for linear and non-linear programming presented together within a single hierarchy of a designated category. The blending may further include managed content relevant to the designated category, where desired. Such designated categories may include television programming categories and/or content categories. The options for linear and non-linear programming may be presented together within a single screen of the user interface.

Systems, devices, and methods for providing alternative content in audio-video streams are disclosed. A manifest data structure including data reflective of a plurality of content segments is generated. At least one alternative content indicator, each indicating one of said plurality of content segments as being an alternative content segment is obtained. The manifest data structure is modified to remove data reflective of those of said plurality of content segments that are not indicated by said one of said alternative content indicators as being an alternative content segment. Upon receiving a request from a client device to view alternative content, the modified manifest data structure is sent to the client device.

Systems and methods are disclosed for generating a content structure that can then be used as a content design building block. Specifically, new content can be automatically generated by combining, replacing or mixing and matching objects, actions, settings, effects, audio, etc., from any number of previously stored content structures to create a new content structure, which is then rendered as a new content segment. Content segments are then stitched together to generate a finished content stream. In this way, new and original content can be created without the traditionally expensive and labor-intensive filming or computer animation processes.

A device configured to display a first video scene and a progress bar for a Hypertext Markup Language (HTML) video and to receive a user input that indicates a time instance value on the progress bar. The device is further configured to identify a first source scene identifier for a second video scene and an animation identifier that is linked with the second video scene based on the time instance value. The device is further configured to identify HTML code that is associated with the first source scene identifier and the first animation identifier and to compile the identified HTML code to render the second video scene. The device is further configured to generate a scaled second video scene by reducing a size of the rendered second video scene to fit a preview frame and to display the scaled second video scene in the preview frame.

A device configured to receive a video request that includes source scene information for generating the plurality of video scenes for a Hypertext Markup Language (HTML) video. For each video scene, the device is configured to identify a video scene from the source scene information and to assign a video scene entry in a video timing map to the identified video scene. The device is further configured to identify animation instructions for animations associated with the identified video scene from the source scene information and to populate the video scene entry in the video timing map based on the animation instructions for the animations that are associated with the identified video scene. The device is further configured to output the video timing map.

A system for instant assembly of video clips through user's interactive performance, comprising a device operated by a user, wherein the device comprises: user interface means configured for input and output interaction with the user; a processing unit and a memory configured for the creation of a new video assembled appending a plurality of video clip segments extracted from a plurality of video clips; and an I/O unit configured for access to the plurality of video clips; the user interface means are configured to detect a sequence of manual assembling commands, and to display the plurality of video clip segments, the display order of the video segments being defined by the sequence of manual concatenation commands; the processing unit and the memory are configured to record the appending process of the video segments extracted from a plurality of video clips.

One or more methods and systems are provided for encoding, decoding and playback of a video content in a client-server architecture. The invention proposes a video encoding and decoding method that includes identification of activities in the video content, identification of corresponding API's with related parameters corresponding to activity and storing those API's along with base frame and object frame in the database. In this invention, animation API functions are created for unknown/random activities. The playback involves decoding the data, which is a set of instructions to play the animation with given objects and base frames, and animating object frame over base frame using said API functions.

A multi-window user interface (UI) is presented in various configurations and operational uses to leverage the relatively large display canvas afforded by large screen display devices such as 4K or 8K displays. Along with the various “Multiview” aspects, content delivery techniques, content selection techniques, and level of service techniques also are presented.
