APPARATUS AND METHOD FOR PROVIDING THE AUDIO METADATA, APPARATUS AND METHOD FOR PROVIDING THE AUDIO DATA, APPARATUS AND METHOD FOR PLAYING THE AUDIO DATA

摘要

PURPOSE: An audio metadata providing device, a method thereof, an audio data playback device, and a method thereof are provided to output multi-channel audio with various methods by combining audio raw data with audio metadata including the channel information of the audio raw data. CONSTITUTION: An audio metadata providing device (210) comprises an audio metadata generator (220) and an audio metadata transmission unit (230). The audio metadata generator generates audio metadata including the channel information of audio raw data. The audio metadata transmission unit transmits the audio metadata to an audio data playback device (250). An audio raw data providing device (240) transmits the audio raw data to the audio data playback device. The audio raw data playback device reproduces the audio raw data by analyzing the received audio raw data and the audio metadata.
