  • Localization of customer premises equipment in a digital communication network
    Patent number: 9762958
    Abstract: In one embodiment, a localization beacon is inserted into a digital communication signal by a localization device. The resulting modified signal is transmitted to customer premises equipment (CPE). One or more CPE devices monitor incoming signals to detect the presence of a localization beacon. If a localization beacon having certain characteristics is not received, the one or more CPE devices are configured to disable one or more CPE features.

  • Resource-adaptive management of video storage
    Publication number: 20050074063
    Abstract: A method for providing adaptive video compression includes encoding a video stream in a first compressed format, storing the video stream in a storage device, retrieving the video stream from the storage device, decoding the video stream, encoding the video stream in a second compressed format, and storing the video stream in the storage device. Systems and other methods for providing adaptive video compression are also disclosed.
