A method for streaming live video includes encoding a video stream on a server, where the server is connected to a client through a network. The server receives a request from the client for a memory address of a first video frame and checks if the memory address of the first video frame has been bit shifted in a direct mapped memory buffer to determine if the first video frame is available. The server provides a memory address of an output video frame to the client in response to the request.

The present invention, disclose a method for cashing video which is distributed through data communication network, implemented by one or more processors operatively coupled to a non-transitory computer readable storage device, on which are stored modules of instruction code that when executed cause the one or more processors to perform: generating Multi part single video file encoded in a single compression container, logically partitioned to multi parts; determining and maintaining expiration dates for each part of video, wherein the expiration date of at least two video parts is different; Caching video parts based on video partitions in at least one main original server and local memory; upon request for the multi part video, checking validation (expiration date) of each video part fetching or retrieving each video part from local or remote caching location based on expiration date of said video part; generating video stream composed of all retrieved validated video parts.

A media server is hosted in a service provider's network so that media content can be stored from or rendered to a private network such as a Digital Living Network Alliance network. Media content may be stored by accessing the media server or by downloading the media content to the media server. Support of set top boxes interacting with voice-on-demand (VOD) controllers and computers interacting with IP-based video content servers are integrated through the media server. Consequently, VOD assets can be played on IP-based devices and IP-based content can be played on set top boxes. A gateway function converts IP-based content to a VOD asset, and renders the VOD asset to a set top box while mapping digital rights management information for the VOD asset. Conversely, the gateway function may convert a VOD asset to IP-based content that can be played on an IP-based device.

A system according to one embodiment disclosed in the present document may comprise at least one network interface, at least one processor, and at least one storage apparatus, wherein the storage apparatus includes instructions that, when executed, cause the processor to: store uploaded video data in the storage apparatus, without transcoding video data to be streamed; receive a first request for streaming of the video data; when the video data to be streamed at the first request is not available on the storage apparatus, transcode the video data in order to stream same; stream the transcoded video data to a first external device through the interface; receive a second request for streaming of the video data; and stream the stored transcoded video data to a second external device through the interface, without additionally transcoding the video data.

A video information periodic broadcasting method includes segmenting video information with an equal duration to obtain video segments S.sub.i of each time series, where i is the segment serial number of the video segments. The video segments S.sub.i are connected in series in an order of ascending the segment serial numbers. Segmenting each video segment S.sub.i with an equal duration to obtain video sub-segments S.sub.i,j of each time series, where the number of the video sub-segments S.sub.i,j of each time series is equal to the segment serial number of the video segments corresponding to the same time series, j is the sub-segment serial numbers of all the video sub-segments of the video segment. The video sub-segments S.sub.i,j are connected in series in an order of ascending the sub-segment serial numbers to form the video segment S.sub.i. Transmitting the video sub-segments through multiple periodic broadcasting channels with an equal bandwidth.

A broadcaster device generates a live stream including video-based commentary regarding a live event combined with an audio and/or video feed of the live event itself. A viewer device receives a copy of the integrated live event and commentator stream and synchronized event information (e.g., real-time scores), and displays the integrated stream and the event information (e.g., as a “scorebug”). Viewers of a given live event may seamlessly select amongst different broadcasters for the same live event to access different integrated live event and commentator streams respectively synchronized with the event information. A social media platform is provided in tandem with live streaming of digital content relating to live events to allow a given broadcaster and their associated viewers to communicate with one another, comment on the event and/or the broadcaster's live stream, and send digital gifts.

Systems and methods are provided for generating an augmented reality display for users of augmented reality devices. Features provided in the AR displays may be used to update a non-augmented reality display. In addition, interactions in the AR displays may also be incorporated into the non-augmented reality display.

To appropriately prevent an image with disadvantageous or inappropriate imaged content from being transmitted when such imaged content is generated in a use case such as real-time distribution of a captured image, and to prevent mistrust of a viewer due to malfunction or the like. Therefore, a transmission unit is caused to execute transmission of a first image that is delayed by a delay processing unit. If a switching trigger is detected during this time, the image that the transmission unit is caused to transmit is switched from a first image to a second image that is reproduced by a reproduction unit.

Multiple segmentation servers are synchronized to provide failover capacity in such a way that should a failover occur, the segment numbers/playlists/encryption keys/decryption keys are identical on each of the segmentation servers. Synchronizing the contents of a segmentation server on one or more backup segmentation servers ensures that the delivery of a content stream is immune to the failure of segmentation servers, provided at least one segmentation server remains fault-free. A caching server may further facilitate the fault tolerance by checking the availability of the individual segmentation servers, collect content segments from one of the segmentation servers, and serve the content segment to clients. The caching server automatically checks a primary segmentation server to ensure it is available (e.g., online), and provides automatic failover to a backup segmentation server should the primary server experience a fault (e.g., go offline).

The described technology is generally directed towards validating content selection graphs for use in an in-memory content selection graph data store. When a content selection graph data is generated, the graph nodes can correspond to prebuilt response data. The response data for any of the nodes can be verified against rules based on the type of a node, for example, as well as based on client-specific information for types of clients. The overall validation process can validate the content selection graph for subsequent use, can result in errors or warnings being logged (which may or may not render the graph unusable, e.g., depending on severity), or can fail the content selection graph. If validated, the content selection graph can be used to rapidly return response data when content from the graph is requested.
