FIELD: playback and recording of audio/video information.
SUBSTANCE: method includes compressing information in real time scale to blocks, containing variable amount of compressed data, and playback parameters are determined dependently on compressed data. Playback parameters contain access list, having components, while each following component is connected to following range of fixed playback time and contains block pointer within said range. Access to information in real time scale may be received in playback device in chosen playback time moment. Respective component in access list is determined by division of selected time value on range value. Component provides a block pointer, appropriate for selected moment of playback time. For calculating address in selected playback time moment within range, interpolation may be used, and precision may be increased by reserve parameter, which points to maximum space between block having selected playback time, and interpolated address.
EFFECT: higher efficiency.
