US 2019/0164560 A1 · BROADCAST TRANSMITTING APPARATUS AND BROADCAST TRANSMITTING METHOD FOR PROVIDING AN OBJECT-BASED AUDIO, AND BROADCAST PLAYBACK APPARATUS AND BROADCAST PLAYBACK METHOD

Abstract

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.

Claims10

Dependent claims

A broadcast playback apparatus, comprising:

a multichannel audio signal determining unit to determine whether an encoded multichannel audio signal in a bitstream is an object-based audio signal, based on audio identification information;
and
an audio decoder to decode the encoded multichannel audio signal, when encoded the multichannel audio signal is the object-based audio signal.

Dependencies are inferred from the claim text.
