  • Publication number: 20190199765
    Abstract: A method and system is provided for controlling bandwidth rate limiting and client rendering rate limiting in a video delivery network. The method provides network service providers with a means for overriding video delivery data rates selected through dynamic client bitrate adaptation, as well as video data rendering rates of the clients, to limit the impact of network congestion. A system is also specified for implementing a client and a proxy computer in accordance with the method. The system works transparently with standard HTTP-based video delivery systems and includes an HTTP proxy cache infrastructure to support bandwidth rate limiting and client rending rate limiting. The system further provides for administrative overrides of client bitrate selection and client bandwidth usage.

  • Publication number: 20180005364
    Abstract: A dual mode inspector includes an optical inspector configured to detect a defect located at a first location on a sample, a microscope configured to capture an image of the defect at the first location on the sample, and a platform that is configured to support the sample. The sample is not removed from the platform between the detecting of the defect located at the first location on the sample and the capturing of the image of the defect at the first location on the sample. The dual mode optical inspector also includes a controller that causes the optical inspector to detect the defect located at the first location on the sample and causes the microscope to capture the image of the defect at the first location on the sample. The dual mode inspector also performs scanning lens distortion correction to improve the capturing of defect images.
