FIELD: information technologies.
SUBSTANCE: system and method are proposed to indicate points of switching from lower level to higher one at the level of file format for efficient switching of scalable flows in flow servers and at local reproduction of files. Also the present invention proposes system and method for indication of switching points from lower level to higher in bit video flow, for instance to provide for intellectual forwarding of scalable levels in network elements, capable of recognition of media data, or computationally scalable decoding in receivers of flow.
EFFECT: provision of simple and efficient switching from lower level to higher one for adaptation of scalable flow without necessity in detailed selection and analysis of bit video flows by flow server, and thus reduction of computational and implementation resources.
