    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 includes service management circuitry to dynamically deploy a plurality of service agents in response to dynamic assembly of a corresponding chain of services that each provide different service functionality. The different service functionality can be provided to an operational network device by different respective network devices over a network. The system can include network interface circuitry to transmit the service agents over the network to monitor performance of the respective network devices providing respective services included in the chain of services. The network interface circuitry can receive service performance information from each of the service agents. The performance information can include information indicative of the performance of the respective network devices. The service management circuitry can analyze the received service performance information and manage the chain of services.

    Abstract: A network may include multiple allocations. The allocations may include: a first allocation encompassing central infrastructure, such as central office servers, data centers, or other core infrastructure; an second allocation encompassing gateway elements or other central consumer premises network infrastructure; and a third allocation encompassing nodes, such as client devices, terminals, or other nodes. A virtualization management engine may coordinate resources from the various allocations to support virtual functions distributed over multiple allocations of the network. The virtualization management engine may determine the distribution across the allocations for the virtual functions. The virtualization management engine may be implemented as a virtual function and be distributed across the allocations of the network.

    Abstract: A system controls a transmission of a sequence of compressed video data from an encoder buffer to a network for delivery to a decoder buffer. Control of the transmission includes to: determine characteristics of a video transmission path between the encoder buffer and the decoder buffer, the characteristics comprising at least one of a buffer size of the decoder buffer, an input rate of the decoder buffer, and a buffer size of an equivalent intermediary buffer of the video transmission path; determine a transmission rate from the characteristics of the video transmission path and from the sequence of compressed video data, the transmission rate being determined such that a target quality of service value can be guaranteed for the entire sequence of compressed video data transmitted at the determined transmission rate to the decoder buffer; and control transmission of the sequence of compressed video data at the determined transmission rate.

    Abstract: A system may receive an input stream for a coding operation by a coding device. The system may determine a processing device to assist the coding device with the coding operation. The processing device may generate an indicator containing coding information or other coding assistance by processing the input stream. The processing device may send the indicator to the coding device. In some cases, the indicator may be embedded in the metadata of the stream by the processing device. The indicator may be extracted by the coding device. After reception of the indicator, the coding device may execute the coding task while using the information in the indicator to assist.
