FIELD: mp3 playback.
SUBSTANCE: additional capabilities of playback control and/or editing ("trick play") are applied to the initial data stream. Stream contains headers and signal data which interleave with each other. Each header defines the interval to the next header; each header corresponds to the frame of signal data. Header is associated with a pointer which defines the starting point of signal data for this frame relative to the header. Before applying the additional playback control capabilities ("trick play") the initial data stream is converted into a temporary data stream of the same type that of the initial stream. During the conversion frame data is moved so that every frame contains data which corresponds only to this frame. At the same time frame header are modified with the purpose of changing the bit length of the frame so that frame data fully fits into the frame.
EFFECT: additional mp3 playback capabilities.
