Just-in-Time Distributed Video Cache
A video optimizer receives a request to optimize a source file and stream the optimized file. The request may be accompanied by a key uniquely identifying the original source file to be optimized and an optimized version of the source file to stream to the client. The key uniquely identifies the source video file as it exists on an origin server to prevent transmission of modified source video and the optimized version of the source file by optimization parameters to ensure compatibility with the user device. The video optimizer queries a cache database in response to the received request, which contains references keys and locations of optimized source files among local caches in a cluster of video optimizers. The cache database responds indicates whether a matching optimized version of the source file exists in a local cache of a given video optimizer in the cluster.
Electronic device and method of operating the same
An electronic device includes a display, a communication interface, a memory storing one or more instructions, and a processor. The processor, by executing the one or more instructions, is configured to, receive a user input for processing a second content while displaying a first content image on the display by processing a first content, identify whether a resource is available for processing the first content and the second content in the electronic device, based on the resource for processing the first content and the second content being unavailable in the electronic device, identify a peer device which has available resource to process the second content, transmit a request for processing the second content to the peer device, receive, through streaming, result second content which results from processing the second content by the peer device, from the peer device, and display, in addition to the first content image, a second content image corresponding to the result second content, on the display.
Systems and methods for streaming media content during unavailability of content server
Systems and methods are described herein for streaming during unavailability of a content server. Upon determining that there are conditions indicating buffering issues during delivery of a media asset, a server determines a first group of devices suitable for receiving the media asset from the server and sharing the media asset on a peer-to-peer network. Then, the server determines a second group of devices suitable for receiving the media asset on a peer-to-peer network from a first group device. The server then determines groupings within which to share and receive the media asset. Next, the server transmits instructions to the devices in the first group to maintain in buffer and share certain portions of the media asset with the second group devices within their grouping. Finally, the server updates information detailing the media asset portions the devices are maintaining in buffer and sharing.
TRANSMISSION DEVICE, COMMUNICATION SYSTEM, TRANSMISSION METHOD, AND COMPUTER PROGRAM PRODUCT
A transmission device according to an embodiment includes one or more processors. The processors divide a plurality of pieces of transmission data to be transmitted into first data and second data. The processors transmit the first data to a server device configured to distribute the transmission data to a reception device. The processors store the second data in storage. The processors receive, from the reception device or the server device, a request for transmission of the second data. The processors transmit the second data to the server device in accordance with the request for transmission.
Apparatus and methods for content storage, distribution and security within a content distribution network
Apparatus and methods for content fragmentation, distribution, protection, and re-constitution within a content distribution network. In one embodiment, the apparatus and methods enable distribution of content fragments to edge nodes (which may include user or subscriber CPE), thereby enabling edge networks or membership groups to be established wherein content can be shared solely at the edge. In one variant, high data bandwidth, symmetric uplink/downlink, low latency PHY links (e.g., 5G NR-compliant wireless interfaces) between the edge nodes participating in the edge networks or membership groups are used such that particular quality of service/experience performance requirements can be met. Distribution of the fragments also advantageously enhances redundancy and security.
Tiered digital content recording
A digital content recording network controller device determines a first content of a set of content to be more likely to be requested by a user of a content access device than a second content of the set of content based on monitored behavior of the user. The device stores the first content in a first storage device of a tiered group of storage devices and stores the second content in a second storage device of the tiered group of storage devices wherein the content access device is located closer to the first storage device than the second storage device. This balances storage load with accessibility, resulting in a faster responding system that does not require as much storage.
Video file storage prediction process for caches in video servers
In some embodiments, a method receives a first set of video files at a node that delivers video files to client devices and receives a second set of video files. The second set of video files are predicted to be delivered by the node to a client device during a time period. The node receives a request for a video file from a client device and determines whether the video file is stored in the first set of video files and the second set of video files. When the video file is stored at the node, the node sends the video file from the first set of video files and the second set of video files. When the video file is not stored in the first set of video files and the second set of video files, the node sends a request for the video file to another node.
SYSTEMS AND METHODS FOR STREAMING MEDIA CONTENT DURING UNAVAILABILITY OF CONTENT SERVER
Systems and methods are described herein for streaming during unavailability of a content server. Upon determining that there are conditions indicating buffering issues during delivery of a media asset, a server determines a first group of devices suitable for receiving the media asset from the server and sharing the media asset on a peer-to-peer network. Then, the server determines a second group of devices suitable for receiving the media asset on a peer-to-peer network from a first group device. The server then determines groupings within which to share and receive the media asset. Next, the server transmits instructions to the devices in the first group to maintain in buffer and share certain portions of the media asset with the second group devices within their grouping. Finally, the server updates information detailing the media asset portions the devices are maintaining in buffer and sharing.
Storage system
In one embodiment, a method includes receiving a stored copy request indicating data and including a request identifier, scheduling publication of the data to an object store, and sending a subscription request indicating the data and the request identifier to the object store. In another embodiment, a method includes receiving a publication request indicating data to be copied, wherein the publication request is a recording request indicating a channel and a timespan, receiving one or more subscription requests for the data, receiving the data, and generating a copy of the data for each subscription request.
DYNAMIC CONTENT STEERING BASED ON SERVER AND CLIENT DEVICE CAPABILITIES
The disclosed computer-implemented method includes determining that incoming media item requests are to be skewed from a random distribution among server nodes, using a random distribution algorithm, to a directed distribution among the server nodes. The method then includes identifying, in a loading assignment, which media items are to be loaded onto specific server nodes to produce the directed distribution of media item requests. The method next includes preloading the identified media items onto the server nodes according to the loading assignment and receiving media item requests for the preloaded media items. The method then includes routing the received media item requests to the server nodes using the random distribution algorithm, where the random distribution algorithm is skewed to the directed distribution based on the preloading of the media items according to the identified loading assignment. Various other methods, systems, and computer-readable media are also disclosed.
