  • Still frame detection in video data
    Patent number: 11706415
    Abstract: Still frame detection for single pass video data, including: determining that an average quantization parameter of a frame of video data falls below a quantization parameter threshold; determining whether an amount of skipped macroblocks in the frame meets a skipped macroblock threshold; and responsive to the amount of skipped macroblocks exceeding the skipped macroblock threshold, identifying the frame as a still frame.
    Type: Grant
    Filed: December 28, 2020
    Date of Patent: July 18, 2023

  • Network congestion prediction
    Patent number: 9197565
    Abstract: To control the transmission of real time transport packets over a network, incoming packets received over the network from a transmitter are monitored. A statistical analysis is performed on the received packets to determine network congestion. A message is sent to the transmitter to control a transmission parameter in accordance with the determined network congestion.
