  • Patent number: 10051294
    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.

  • Publication number: 20160095110
    Abstract: A method includes detecting, using a WiFi access point, channel use data indicating traffic on a plurality of channels of an unlicensed LTE band in a wireless network. The method further includes providing the channel use data to a Long Term Evolution (LTE) access point. The method further includes selecting, using the LTE access point, a channel for use in transmitting data by the LTE access point from among the plurality of channels based on the channel use data from the WiFi access point. The method further includes providing, from the LTE access point, an indication of an upcoming transmission configured to transmit data on the channel to the WiFi access point. The method further includes broadcasting one or more messages from the WiFi access point to one or more WiFi nodes, the one or more messages configured to prevent the WiFi nodes from transmitting on the channel.

  • Patent number: 9084012
    Abstract: A media gateway (MG) that services a plurality of client devices, may be handled at least a portion of video conferencing (VC) processing during a VC call between at least one of said plurality of client devices and at least one other VC client. The portion of the VC processing handled by the media gateway may be offloaded from a centralized VC multipoint control unit (MCU). The MG may handle one or more VC MCU functions, which may comprise video conferencing call control and/or management and/or audio/video (AV) transcoding. The MG may perform localized quality of service (QoS) management, to select, and adaptively control and/or configure resources and/or local links used in the MG and/or in VC clients or neighboring MGs connected to the MG, during VC operations, such as in generating, handling, and/or communicating data or content exchanged during VC calls.

  • Patent number: 8917745
    Abstract: Different data communication architectures deliver a wide variety of content, including audio and video content, to consumers. The architectures employ channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, the communication architectures distribute data across multiple orbital angular momentum channels in the bonded channel group.

  • Patent number: 8812740
    Abstract: An apparatus and a system are provided to proxy one or more media signals between at least one local client device and at least one remote client device. For instance, the apparatus can include a first network interface, a media dispatcher, and a second network interface. The first network interface can be configured to receive a single media signal of the one or more media signals from a local client device via a first communication network with an asymmetric communication protocol (e.g., Data Over Cable Service Interface Specification and Digital Subscriber Line). The media dispatcher can be configured to duplicate the single media signal into a plurality of duplicate media signals. Further, the second network interface can be configured to transmit the plurality of duplicate media signals to a plurality of remote client devices over a second communication network.

  • Patent number: 7349291
    Abstract: A method and apparatus for controlling pulses in a pulse-echo level measurement or time-of-flight ranging system. The apparatus comprises a controller, a transducer, and an energy storage device. The energy storage device is operatively coupled to the transducer through a relay. The relay is enabled and disabled by the controller and in the disabled state the energy storage device is allowed to accumulate energy. The energy is stored in the energy storage at a variable voltage level. The controller includes a component for determining a voltage level corresponding to an acceptable confidence level for echo pulses. The controller includes another component for determining a voltage level an increased response time.

  • Publication number: 20050076385
    Abstract: A programmable channel scanning and acquisition method for a cable modem first performs a fast scan and then a slow scan to identify channels supporting cable modem services. The fast scan involves only a check of the cable modem AGC lock. A list of potentially operational channels is assembled and scanned. The list includes, in order of preference, the last known good channel, golden channels that are likely to support cable modem services, “learned” golden channels consisting of previous last known good channels, and other channels within the frequency plan range. The list omits channels on a “black list” known not to be operational and channels outside of the frequency range, except during registration. The method may be optimized by the setting of various parameters for operation in a DOCSIS or EuroDOCSIS environment.
