Abstract
The present invention relates to a method of calculating temporal information of frame-based audio stream data, and more particularly, to a method of calculating temporal information of frame-based audio stream data, in which it can calculate time related information depending on the playback of stream data even when bitrate or timetable information is not included in header information when audio or voice stream data consisting of a frame format are played back. Audio and voice stream data applied at this time includes stream data of a type in which several frames form one bit stream block as well as stream data constructed on a frame basis.
