  • Patent number: 11463296
    Abstract: Disclosed are procedures for measuring the modulation quality of each message resource element in a failed 5G or 6G communication modulated according to pulse-amplitude modulation, thereby revealing the most likely fault locations in the message. A second copy of the message can be merged by selecting the highest quality message elements from each version, where the quality is related to how far each message element's modulation deviates from the calibrated “states” of the modulation scheme. The receiver may also determine directional information based on the modulation of each message element, and may compare versions to determine the most likely correct state of each message element. Such strategies may directly recover the original message, or may greatly reduce the number of variations that need to be tested.

  • Patent number: 11212567
    Abstract: A reception apparatus includes receiver and processing circuitry. The receiver circuitry receives a broadcast stream that includes a television service selected by a user. The processing circuitry receives a user selection of the television service included in the broadcast stream and determines whether the selected television service is a digital rights management (DRM) protected service. When the selected television service is determined to be the DRM protected service, the processing circuitry outputs a quick response (QR) code for display, monitors the received broadcast stream for a DRM license that is associated with the unique identifier of the reception apparatus, acquires the DRM license that is associated with the unique identifier of the reception apparatus from the received broadcast stream, and decrypts at least one media component of the selected television service using the acquired DRM license.
