Functionally Layered Video Coding for Awareness Video Communication

Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a new video coding system which transmits functionally layered data for “awareness” communication. The system displays “awareness”, which is defined as a “blurred” and “semi-transparent” person region by transmitting minimum data necessary for displaying the awareness. The minimum data contains (1) person region and (2) lower frequency band signals of the region for displaying blurred person and (3) higher bit-planes of the band signals for displaying blurred and semi-transparent person. Scenery without person is previously transmitted. It becomes possible to reduce redundancy in data transmission since (2) and (3) above are implemented by the “band decomposition” and the “bit-plane decomposition” of the JPEG2000 (JP2K) international standard respectively.
