Data Processing Device

摘要

Device for analyzing streaming audio-video data, characterized in that it comprises a selector (20) designed to determine input data relating to an audio stream or to a video stream in the streaming audio-video data, a converter (22) designed to produce image data at a frequency chosen on the basis of the input data, an encoder (24) designed to produce compressed data on the basis of the image data, and a projector (26) designed to produce imprint data on the basis of the compressed data, the converter (22) being designed to produce the image data in the form of an image of fixed dimension, the encoder (24) being designed to work successively on each image described by the image data, and the projector (26) being designed to produce the imprint data as a stream on the basis of the weight of the compressed data produced successively.
