Abstract. In the first part of article the possibilities of video compression by downscaling of parameters (bit depth, resolution) are studied and rejected. In the second part of the article the approach to compression, which utilizes saliencies of signal, is studied. Algorithms of object detection and semantic compression are described. The key feature of compression algorithm is supplement of video stream by information about parameters of objects. Final part consists of experimental study of compression ratio of proposed algorithm.

Keywords: object detection, parameters of object, video compression, JPEG, metadata.
