A media switch enables a terminal to access content by receiving a content request from a terminal for a first piece of content to be distributed over a cable system, identifying.sup., a personal channel within resources available in the cable system to distribute the first piece of content to the terminal, transmitting access information to the terminal to enable the terminal to access the first piece of content through the personal channel, and interfacing with a cable headend to provide the first piece of content on the personal channel.

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.

A cloud recording system, a cloud recording server, and a cloud recording method are provided. The cloud recording system includes an image source device, a recording device, and a remote storage device. The image source device provides an audiovisual streaming data. The recording device is used for receiving the audiovisual streaming data. The recording device stores at least one recording time parameter and includes a capture unit and a conversion unit. The capture unit is used for capturing a partial audiovisual streaming data in accordance with the recording time parameter. The conversion unit is used for converting the partial audiovisual streaming data into a captured file. The recording device is configured to transmit the captured file to the external of the recording device. The remote storage device is connected to the recording device and is used for receiving and keeping the captured file.

Systems, devices, apparatuses, components, methods, and techniques for predicting user and media-playback device states are provided. Systems, devices, apparatuses, components, methods, and techniques for representing cached, user-selected, and streaming content are also provided.

Systems, methods, and devices of the various embodiments disclosed herein may provide a protocol and architecture for decentralization of content delivery. Various embodiments may provide a client based method for content delivery from content delivery networks (CDNs) via tiered caches of content hosted by Internet Service Providers (ISPs). In various embodiments, content delivery protocol (CDP) messages may enable clients to discover local cache network topologies and request content from a CDN based on a discovered local cache network topology. In various embodiments, security may be provided for the content delivery by the use of key encryption and/or file hashing.

A method is provided, including the following operations: executing a cloud video game in a data center; streaming video generated by the executing cloud video game over a network to a client device; deploying a cloud gaming proxy to an edge compute that is proximate to the client device; wherein the cloud gaming proxy buffers the video and retransmits lost packets of the video to the client device.

A digital content storage and delivery system (DCSDS) includes a network interface to communicate data between the DCSDS and a destination device via a network data communication link having limited bandwidth. An input interface receives digital content for handling by the DCSDS. A storage architecture stores recorded video content on behalf of subscriber end users for on-demand playback via the network data communication link, and it caches live streaming video content for distribution via the network data communication link. The DCDS may monitor bandwidth usage of the network data communication link, determine current bandwidth demand for playback of recorded video content stored at the storage architecture, and reserve at least some of the limited bandwidth of the network data communication link to satisfy the determined current bandwidth demand. The available bandwidth is allocated to support distribution of live streaming video from the DCSDS.

Prior to receiving a request from a client device for information from a content distribution network (CDN), a Reductive Edging device predictively requests the information from the CDN based on prior user activity and stores it in memory. The Reductive Edging device is thus configured to respond to the request from the client device for information from the CDN with the information stored in the memory prior to receiving the request.

Aspects of present disclosure include devices within a transmission path of streamed content forwarding received data packets of the stream to the next device or “hop” in the path prior to buffering the data packet at the device. In this method, typical buffering of the data stream may therefore occur at the destination device for presentation at a consuming device, while the devices along the transmission path may transmit a received packet before buffering. Further, devices along the path may also buffer the content stream after forwarding to fill subsequent requests for dropped data packets of the content stream. Also, in response to receiving the request for the content stream, a device may first transmit a portion of the contents of the gateway buffer to the requesting device to fill a respective buffer at the receiving device.

The present application discloses techniques for playback of live broadcast content. The techniques comprise receiving a request of playing live broadcast content from a client computing device, wherein the request comprises information indicating a first address associated with the live broadcast content, and the request further comprises a playback time parameter indicating a playback time length; generating a second address based on a current system time parameter, the first address, and the playback time parameter; obtaining live broadcast content based on the second address and transmitting the live broadcast content to the client computing device.
