Abstract:
1. A method of calculating temporal information of frame-based audio stream data in a system that plays back the audio stream data in case that bit rate information is not included in a frame header, the method comprising the steps of: calculating, by a processor, a decoding frame count per unit time, when the audio stream data encoded as a frame format are input to a buffer; counting, by the processor, a frame count of the audio stream data input to the buffer; calculating, by the processor, a data size per frame of the audio stream data stored in the buffer using the frame count of the audio stream data; and calculating, by the processor, a total playback time of the audio stream data by dividing the entire size of the audio stream data by a multiplication of the decoding frame count per unit time and the data size per frame, wherein the data size per frame is variable.
