Systems, devices, and methods for streaming or otherwise delivering media content over a network are provided. One exemplary method of streaming media content over a network using a RS-DVR system involves receiving, at the RS-DVR system, a request for a portion of the media content from a media player on a client device via the network, receiving, at the RS-DVR system, the portion of the media content from an origin server on the network, buffering the portion of the media content at the RS-DVR system, and transmitting the portion of the media content to the media player on the client device. The portion of media content may be transmitted using a modified transport layer protocol, and in some embodiments, marked as non-cacheable.

A method for caching a piece of content in a content distribution network of a first network, a browser module running on a user terminal and allowing access to content by using encrypted sessions, the browser module being associated with a proxy server of a second network interconnected with the first network, the proxy server controlling a current session status between the browser module and a content provider. The method includes: the browser module sending a request relating to the content to the content provider; the proxy server obtaining a piece of information relating to the request; the browser module receiving the requested content; and the proxy server commanding the browser module to cache the content in the content distribution network.

Systems, devices, and methods for streaming media content over a network are provided. One exemplary method of streaming media content over a network involves transmitting one or more portions of the media content to a client device via a delivery route between a content delivery source and the network, determining a performance metric associated with the transmitting of the one or more portions via the delivery route, and dynamically adjusting the delivery route between the content delivery source and the network based at least in part on the performance metric.

Herein is disclosed a media content delivery device, comprising one or more content demand processors, configured to determine a first location, the first location being a location for media content receipt; determine a second location, the second being a location for media content delivery; one or more vehicle coordination processors, configured to select a vehicle for media content transportation; cause the vehicle to wirelessly receive the media content at the first location; and cause the vehicle to deliver the media content at the second location.

A system and method for optimizing defragmentation of content in a content delivery network (CDN). In an example, a manifest available to the content delivery node with respect to a particular content as well as segment files stored in a database cache of the content delivery node are analyzed to determine if any segment files referenced by the manifest are absent from the database cache. If so, one or more delivery rules associated with the content delivery node based on historical ABR asset delivery patterns may be applied to determine representations of the absent segment files that satisfy the one or more delivery rules. After determining compliant representations of the absent segment files, they may be pulled from another content delivery node of the CDN (e.g., a parent node or an edge server node).

Systems and methods for mirroring and transcoding media content are provided. In some embodiments, media content stored on a user equipment device is mirrored on a remote server, and the mirrored copy is transcoded and provided to other user devices in a media content format that is appropriate for the user devices. By so doing, the present invention not only provides a convenient and easy way for users to backup media content and access the media content from virtually any device, but also reduces the complexity and costs associated with maintaining reliable and consistent access to media content across various user devices.

The present disclosure provides a video data storage system, an operation method thereof, and a retrieval server. The video data storage system according to present disclosure includes an index server and at least two storage servers for storing video data. The index server stores a first mapping relationship between a camera identification code and a storage server identification code. Each of the storage server stores a second mapping relationship among a camera identification code, a time range of video data and a physical location of video data in the storage server. The operation method includes: making, by the index server, statistics of an operation hot value of video data operated by all clients, and determining the operation hot value of the video data is greater than a predetermined first threshold; if yes, sending, by the index server, a backup instruction to at least one storage server, to instruct the storage server to back up the video data and update the second mapping relationship. The present disclosure can protect the hottest data using a minimum amount of capacity and bandwidth.

Systems and methods are described to transfer content from a first computing device to a second computing that is not directly accessible from the first computing device. The transfer may be carried out using an application operating on the first computing device that uploads the content to the cloud storage service. The second computing device may operate an application that monitors the cloud storage service for recently uploaded content. When the second computing device detects that content has been uploaded to the cloud storage service, the second computing device may download the content. The second computing device may update a manifest file located on the cloud storage service to indicate that the content was downloaded. Subsequently, the first computing device may access the manifest file and determine that content was downloaded.

A video live broadcast method and an apparatus, where when a regional node receives a video request from a video playing client but does not have a corresponding video stream, information about a regional node that has the video stream is learned by searching the live broadcast record table, and then a stream is pulled from the regional node.
