  • Publication number: 20170359780
    Abstract: A device, system, and method adaptively adjusts monitoring for opportunities. The method is performed at a user equipment (UE) configured to control an operation of a transceiver, the transceiver configured to enable the UE to establish a connection with a Long Term Evolution (LTE) network, the user equipment and the LTE network configured with and utilizing a Connected Discontinuous Reception (CDRX) functionality. The method includes receiving a response from the LTE network for an uplink transmission. When the response is an acknowledgement (ACK), the method includes determining whether a value of a network parameter associated with the connection with the LTE network satisfies a predetermined threshold. When the network parameter satisfies the predetermined threshold, the method includes omitting a monitoring opportunity to verify that the ACK is a true ACK.

  • Patent number: 9094685
    Abstract: Systems and methods of transcoding video bitstreams that employ highly efficient look-ahead approaches to video transcoding. The systems and methods perform video transcoding in the pixel domain to make successive adjustments to estimates of the coding complexity of video frames in input video bitstreams. The systems and methods can employ the adjusted estimates of the coding complexity in a rate control function to provide improved bit allocations for the video frames in transcoded output video bitstreams, thereby enhancing overall perceptual quality.

  • Patent number: 8885050
    Abstract: Systems and methods of perceptual quality monitoring of video information, communications, and entertainment that can estimate the perceptual quality of video with high accuracy, and can be used to produce quality scores that better correlate with subjective quality scores of an end user. The systems and methods of perceptual quality monitoring of video can generate, from an encoded input video bitstream, estimates of one or more quality parameters relating to the video, such as the coding bit rate parameter, the video frame rate parameter, and the packet loss rate parameter, and provide these video quality parameter estimates to a predetermined video quality estimation model. Because the estimates of the video quality parameters are generated from the encoded input video bitstream as it is being received, the systems and methods are suitable for use as QoE monitoring tools.

  • Patent number: 8804815
    Abstract: Systems and methods of objective video quality measurement based on support vector machines. The video quality measurement systems can obtain information pertaining to features of a target training video, obtain corresponding information pertaining to features of a reference version of the target training video, and employ the target training features and/or the reference training features to build video quality models using such support vector machines. Based on the target training features and/or the reference training features used to build such video quality models, the video quality models can be made to conform more closely to the human visual system. Moreover, using such video quality models in conjunction with target features of a target video whose perceptual quality is to be measured, and/or reference features of a reference video, the video quality measurement systems can be employed to predict measurements of the perceptual quality of such a target video with increased accuracy.
