  • Patent number: 10594624
    Abstract: Systems and methods are described for using opportunistically delayed delivery of content to address sub-optimal bandwidth resource usage in network infrastructures that allow subscribers to share forward link resources. According to some embodiments, content is identified as delayable and assigned to a delaycast queue and/or service flow. For example, a server system of a satellite communications system identifies content that can be delayed to exploit future excess link capacity through multicasting and to exploit subscriber-side storage resources. Some implementations attempt to exploit any excess link resources at any time, while others exploit unused bandwidth only during certain times or when a certain threshold of resources is available. Various embodiments also provide content scoring and/or other prioritization techniques for optimizing exploitation of the delaycast queue.

  • Patent number: 9800909
    Abstract: As additional channels are added to a communication system for applications, such as standard density (SD) and eventually high density (HD) Video on Demand (VOD), additional capacity can be realized by reducing the time required to transmit content. A reduction of transmission time (or an increase of the transmission rate) can be achieved by bonding chancels of the communication system. The bonded channels typically provide a statistical multiplexing gain because the additional bandwidth is treated as a large single channel for the download. Bonding channels of the communication system can provide high speed downloading of content, such as video content, far in excess of the playback rate. Using bonded channels can relax the Quality of Service (QoS) requirements of a data stream, such as a video stream, over an internet protocol (IP) network.

The length of the matching range is iteratively increased by checking previous and next symbols in the input data and the dictionary until a matching range length meets a threshold limit or the length of the matching range cannot be increased further. Compressed data corresponding to the input symbols is provided where input symbols are copied over and symbols in a matched range of data are replaced with a representation of their corresponding start location and length in the dictionary.

  • Patent number: 8817694
    Abstract: A satellite broadcasting system is achieved where remote beam forming processors combined with wavefront multiplexers located among distributed ground stations are used to control downlink beam footprints and pointing directions. Digital beam forming (DBF) techniques allow a single satellite download broadcast antenna array to generate multiple independently pointed simultaneous downlinks, which may contain distinct information content. Allocation of some uplink back-channel elements as diagnostic signals allows for continuous calibration of uplink channels, improving downlink broadcast array and user broadcast performance. Wavefront multiplexing/demultiplexing allows all array element signals to be radiated by the broadcasting antenna array, with simultaneous propagation from ground stations to the broadcasting satellites through available parallel propagation channels in the uplinks of feeder links, with equalized amplitude and phase differentials.

  • Patent number: 8774225
    Abstract: Services and service components in a broadcast network may be mapped to disparate physical layer transmission channels (PLPs) using logical layer pipes (LLPs). The use of LLPs allows different service components of a single service to be mapped to physical layer transmission channels (PLPs). Accordingly, service components may be shared among different services. Additionally or alternatively, different functions (e.g., different error detection or correction protocols) may be applied to each service components of a service. A receiver may identify services, service components and corresponding PLPs based on LLP identifiers. The receiver may then access and receive desired services and service components through the identified PLPs.

  • Patent number: 8693504
    Abstract: Customizable, multimedia messaging over a subscriber television system utilizing a service independent framework is provided. A multimedia messaging (MMM) server is generally located at a headend of a cable or satellite system, and an MMM client at a communications terminal located remotely with respect to the MMM server. A service provider or operator defines a message configuration to present the message content to subscribers. The message configuration includes parameters that control the presentation of the message content. The MMM server receives an MMM request from a service application, and generates an MMM request which is sent to the communications terminal, particularly, to the MMM client. The MMM client processes the MMM request, including retrieving message content and/or message configuration. The MMM client presents the message to the subscriber. Since the MMM server and MMM client are platform independent, different services may send uniquely generated and designed messages for presentation.
