New patents are issued by the USPTO on Tuesdays. Both of today's Spotlight Patents concern aspects of digital rights management. Assigned to Verint Americas, the first patent addresses techniques for digital rights management control using video analytics. Assigned to Hitachi (JP), the second patent addresses techniques for an interface that can prevent video signals from being copied easily and which uses a luminance/color difference signal transmission scheme with an excellent harmony with a television circuit.
9,769,542, "System and method for digital rights management control using video analytics," assigned to Verint Americas Inc.
Digital rights management (DRM) of video data is selectively applied to video data by a video processing system that receives a video, comprising a number of frames, and processes at least one frame from the video to determine the contents of the video. The digital rights management for the video is then configured based on the contents of the video.
9,769,448, "Video signal transmitting apparatus and video signal receiving apparatus," assigned to Hitachi Maxell, Ltd. (JP).
An interface is realized that can prevent video signals from being copied easily and which uses a luminance/color difference signal transmission scheme with an excellent harmony with a television circuit. In a video transmission using a digital interface, colorimetry information for defining the conversion from the luminance/color difference signal into a primary color signal and video aspect ratio information are transmitted along with the luminance/color difference type video signal. This allows reproduction of video with high quality and high resolution and also realizes a copyright protection which allows only the users authorized by key information to use the content of the video. With this transmission scheme, it is possible to provide a transmitting apparatus, a receiving apparatus and an interface which highly harmonize with a rationalized television-based circuit.
