USAC AUDIO SIGNAL ENCODING/DECODING APPARATUS AND METHOD FOR DIGITAL RADIO SERVICES |
| 摘要 |
Disclosed is a unified speech and audio coding (USAC) audio signal encoding/decoding apparatus and method for digital radio services. An audio signal encoding method may include receiving an audio signal, determining a coding method for the received audio signal, encoding the audio signal based on the determined coding method, and configuring, as an audio superframe of a fixed size, an audio stream generated as a result of encoding the audio signal, wherein the coding method may include a first coding method associated with extended high-efficiency advanced audio coding (xHE-AAC) and a second coding method associated with existing advanced audio coding (AAC). |

1. An audio signal encoding method comprising:
receiving an audio signal; determining a coding method for the received audio signal; encoding the audio signal based on the determined coding method; and configuring, as an audio superframe of a fixed size, an audio stream generated from the encoding of the audio signal, wherein the coding method comprises a first coding method associated with extended high-efficiency advanced audio coding (xHE-AAC) and a second coding method associated with existing advanced audio coding (AAC), and when the received audio signal is encoded based on the first coding method, the audio superframe comprises syntactic information as to whether the audio superframe comprises header information of the first coding method. |
