FIELD: physics; communication.
SUBSTANCE: present invention pertains to multimedia information transmission systems. The technical outcome is achieved by that, video image, for example, in a multimedia stream is scanned before compression so as to identify symbols, such as graphic characters and alphanumeric characters. The types, positions and sizes of the symbols are recorded for presenting symbolic information. The image is then compressed with or with out compressing the symbols, which can be removed from the image before compression if necessary. The compressed video and symbolic information is sent to a receiver, which decompresses the video, optionally converts the symbols and then inserts them where the symbolic information indicates.
EFFECT: increased efficiency of transmitting compressed multimedia information.
