  • Publication number: 20190289296
    Abstract: Videos may be characterized by objective metrics that quantify video quality. Embodiments are directed to target bitrate prediction methods in which one or more objective metrics may serve as inputs into a model that predicts a mean opinion score (MOS), a measure of perceptual quality, as a function of metric values. The model may be derived by generating training data through conducting subjective tests on a set of video encodings, obtaining MOS data from the subjective tests, and correlating the MOS data with metric measurements on the training data. The MOS predictions may be extended to predict the target (encoding) bitrate that achieves a desired MOS value. The target bitrate prediction methods may be applied to segments of a video. The methods may be made computationally faster by applying temporal subsampling.

  • Publication number: 20190230010
    Abstract: A monitoring station deployed in a network monitors packets over one or more interfaces in the network. The monitoring station identifies a flow in a media session. The flow includes at least one request message that includes a request for a segment or chunk of video content and one or more response messages including the requested chunk. The monitoring determines a start of a chunk in the flow and determines an end of the chunk in the flow. Using the start and end times of the chunk and next or subsequent chunks, the monitoring station determines one or more chunk statistics, such as chunk size, chunk duration and chunk download time.

  • Patent number: 10250579
    Abstract: A capability is provided for securely transferring a file within network-based storage. A capability is provided for securely transferring a user file of a user from a first server to a second server. The first server may be associated with a first service provider and the second server may be associated with a second service provider. The secure transfer of a user file from the first server to the second server may be performed based on a One-Click File Transfer capability in which only a single click by the user is needed in order for the user file to be transferred. The secure transfer of a user file from the first server to the second server may be performed based on a Zero-Click File Transfer capability in which the user file may be transferred without any interaction by the user.

  • Publication number: 20170168994
    Abstract: A manner of facilitating document presentation that may be used to advantage, for example, by a presenter in a meeting room or auditorium setting. A document-presentation system includes a control server that receives a document-presentation indication, for example from a presenter device or another apparatus in a meeting room or associated with a meeting. The control server communicates with the presenter, or user, and determines the document or documents to be presented and a location from which they may be obtained. The control server then sends a presentation notice to a selected render server, which downloads and renders the document. The render server renders the document to a frame buffer in local memory, encodes the pixels read from the frame buffer, and streams the encoded pixels to an adapted display device in a selected location. The render server communicates with the user via the presenter device to start, control, and terminate the presentation.

  • Publication number: 20160294991
    Abstract: Various embodiments provide a method and apparatus providing signaling protocol overload control by enhancing hop-by-hop overload control using cooperation between an “upstream server” or Sending Entity (SE) and the server receiving the signaling request messages and replying with signaling reply messages for a session the “downstream server” or Receiving Entity (RE). In particular, an overload control mechanism for a signaling request transmitted between an SE and the RE allows the RE to receive from the SE a predicted load based on the original un-throttled signaling load information at the SE. The RE may then base decisions such as an overload trigger or a resource scaling decision based on the received un-throttled predicted load at the SE.

  • Patent number: 9106431
    Abstract: The invention includes a method and apparatus for providing media content. The method includes duplicating each packet of an original packet stream for which an associated importance level satisfies an importance condition, inserting each duplicate packet within the original packet stream to form thereby a modified packet stream, and transmitting the modified packet stream toward a wireless terminal adapted for processing the modified packet stream for presenting the media content conveyed by the original packet stream. The duplicate packets may be inserted within respective windows associated with the duplicate packets, wherein each window is determined according to an original packet position associated with the original packet from which the duplicate packet is formed.

  • Patent number: 9107236
    Abstract: The invention includes a method and apparatus for scheduling multicast transmissions in a wireless network by selecting one of a plurality of multicast groups of a cellular region that is permitted to transmit information during a current timeslot. A method includes receiving data rate request values from wireless user terminals of each of a plurality of multicast groups, assigning a data rate to each multicast group using the data rate request values of wireless user terminals belonging to the respective multicast groups, selecting one of the multicast groups using the assigned data rates, and transmitting information to the selected one of the multicast groups at the associated assigned data rate. In one embodiment, the multicast scheduling algorithm may be a multicast proportional fairness (MPF) scheduling algorithm which attempts to maximize utility value of data received by individual users.

  • Patent number: 9030960
    Abstract: A capability is provided for reducing or even eliminating redundant traffic in cellular wireless networks. A method is provided for encoding a target packet in a manner for reducing redundancy of information in the target packet. The method includes identifying a region of the target packet that matches a region of a stored packet, removing, from the target packet, the identified region of the target packet from the target packet, and inserting, within the target packet, an encoding key comprising a hash of the stored packet. A method is provided for reconstructing a packet from an encoded packet that is encoded in a manner for reducing redundancy of information in a network. The method includes identifying an encoding key within the encoded packet, wherein the encoding key comprises a hash of a stored packet, retrieving the stored packet using the hash of the stored packet, removing the encoding key from the encoded packet, and inserting information from the stored packet within the encoded packet.

  • Patent number: 9007978
    Abstract: Various methods and devices are provided to address the need for improved multicast operation. In one method, a station transmits (401) a multicast packet to a plurality of mobile devices and to a group of monitoring stations (MSs). An indication of whether the multicast packet was received by that MS is received (402) from each monitoring station (MS) of the group of MSs. When this indication indicates that the multicast packet was not received, the multicast packet is retransmitted (403) to the plurality of mobile devices and to the group of MSs.

  • Patent number: 8954515
    Abstract: An application proxy is disposed between a user device and an application server. The application server supports an application that is available on the user device. The user device registers with the application proxy for the application. The user device is prevented from transmitting application update request messages to the application server. The application proxy transmits application update request messages to the application server on behalf of the user device. The application proxy receives application update response messages from the application server. The application proxy determines, based on the application update response messages from the application server, whether to send an application update notification message toward the user device. In this manner, application update traffic normally transmitted via the network between the user device and the application proxy is reduced. The application update request and response messages may be polling messages, keep-alive messages, and the like.
