Abstract: Systems and methods for transmitting content are provided. In some aspects, a method includes receiving an indication of a plurality of input streams of content. Each input stream is associated with an input bit rate. The method includes determining a plurality of output bit rates at which to transmit the content to one or more client devices, comparing the plurality of input bit rates to the plurality of output bit rates, and generating, by a server, a plurality of output streams of the content based on the comparison. Each generated output stream is associated with a corresponding output bit rate and includes a transcoded input stream or a non-transcoded input stream. The plurality of output streams is generated such that a number of output streams comprising non-transcoded input streams is maximized. The method also includes transmitting the generated output streams to the one or more client devices.

Abstract: A device and method for providing an adaptive bit rate (ABR) proxy is disclosed. An ABR proxy determines an optimal data format to receive content segments for an audio/video (AV) content item from a source ABR server, and generates, based on that format and/or current network conditions, one or more local AV representations for providing content segments for the AV content item to locally connected devices. A local client device selects a local AV representation, and the ABR proxy provides the content segments for the AV content item to the local device in accordance with the selected local AV representation.

Abstract: A distributed adaptive bit rate (ABR) proxy system may include a gateway device that includes a first transcoder and is configured to receive segments of a content item from an ABR server, and a secondary device that includes a second transcoder and is configured to receive the segments of the content item from the gateway device. The first transcoder may transcode the segments based at least in part on a first ABR profile to generate first transcoded segments, and the second transcoder may transcode the segments based at least in part on a second ABR profile to generate second transcoded segments. The gateway device may advertise the first and second ABR profiles to user devices and may transmit the first transcoded segments to the user devices in response to requests therefor. The secondary device may transmit the second transcoded segments to the user devices in response to requests therefor.

Abstract: A system for layered local caching of downstream shared media in a hierarchical tree network arrangement includes a first network node on a first distribution network having a first caching controller. The first network node configured to store a video segment transmitted on the first distribution network based on a first instruction received by the first caching controller from a central caching controller communicatively coupled to the first distribution network. The central caching controller is located upstream from the first network node. The system includes a second network node on a second distribution network having a second caching controller and communicatively coupled to the first network node. The second network node configured to store a video segment transmitted on the second distribution network based on a second instruction received by the second caching controller from the first caching controller.

Abstract: A device for providing downlink channel access for non-operator devices includes at least one processor circuit. The at least one processor circuit is configured to establish a local connection with an operator device that is serviced by a network operator. The at least one processor circuit is configured to provide, to the operator device over the local connection, a request to establish a connection to a network, the request comprising a destination address. The at least one processor circuit is configured to receive, from the operator device over the local connection, control information for reception of a downlink channel provisioned by the network operator for the operator device. The at least one processor circuit is configured to receive downlink data associated with the destination address on the downlink channel and provide, to the operator device, uplink data associated with the destination address for transmission to the network.

Abstract: A method of processes data such as video information. The method includes providing a request from a gateway to an adaptive bit rate server for a unicast adaptive bit rate stream and converting by the gateway the unicast adaptive bit rate stream into one or more multicast adaptive bit rate streams. The gateway is in communication with user equipment having security paired client devices. The method further includes receiving link conditions between the security paired client devices and the user equipment from the user equipment. The method also includes adapting using the gateway the unicast adaptive bit rate stream in response to the link conditions.

Abstract: The present disclosure is directed to methods and system for managing communication of packets. A transceiver node receives a plurality of IP data packets from an internet protocol (IP) network. The transceiver node separates the IP data packets into a first set and a second set of IP data packets, according to channel conditions of a cellular network and a wireless local area network (WLAN). The transceiver node transmits, to a user device, the first set of IP data packets using a cellular network protocol of the cellular network and the second set of IP data packets using a WLAN protocol of the WLAN, causing the user device to aggregate the first set of IP data packets transmitted using the cellular network protocol with the second set of IP data packets transmitted using the WLAN protocol.

Abstract: A system includes one or more network media service devices, with each network media node operably connected upstream to one or more gateway devices. At least one of the network media service devices is configured to intercept an ABR-related request to receive digital media content for a media channel sent from a client set top box to a remote ABR server located upstream from the at least one network media device, identify a second gateway device that is storing the digital media content, the second gateway device having previously received the digital media content from the remote ABR server, and return a network address of the second gateway device to the client set top box for use by the client set top box to receive the digital media content from the second gateway device. In various implementations, the network address is returned in connection with an HTTP response indicating a redirection to the network address.
