| Abstract(in English) | Streaming-based mobile broadcasting such as terrestrial 1-segment broadcasting and digital audio broadcasting started recently, and download-based mobile broadcasting services which play back stored content on receivers are being considered. These broadcasting services require a function for playing back content in depleted video to encourage viewers to purchase content, in addition to a function that allows only subscribers to view content. Therefore, broadcasters require a digital video scrambling method with variable concealed level to control the video quality of stored content. We propose a digital video scrambling method with variable concealed level for stored content. The method can handle H.264/AVC coding content and the processing load for controlling the concealed level of video is low. We also verify by evaluating video quality and implementation that the proposed method is feasible for actual services. |
