Broadcast transmitting/playback apparatus and method thereof

摘要

A broadcast transmitting apparatus and method, and a broadcast playback apparatus and method for providing an object-based audio by encoding and decoding a multichannel audio signal are provided. The broadcast transmitting apparatus may generate audio identification information used to determine whether the multichannel audio signal is an object-based audio signal. When the multichannel audio signal is determined to be the object-based audio signal, based on the audio identification information, the broadcast playback apparatus may control and output the multichannel audio signal for each channel.

主权项

1. A broadcast playback apparatus, comprising:
a multichannel audio signal determiner configured to determine whether a multichannel audio signal is an object-based audio signal, based on audio identification information, the object-based audio signal being an independently encoded signal; a downmixer; and an audio decoder configured to decode the multichannel audio signal and to send the multichannel audio signal to the downmixer, in response to the multichannel audio signal being determined to be the object-based audio signal.
