ENHANCED VOICE SERVICES (EVS) IN 3GPP2 NETWORK |
| 摘要 |
In various aspects, the disclosure provides for Enhanced Voice Services (EVS) encoding, including encoding an audio signal to obtain an encoded audio signal and a bitrate associated with the encoded audio signal; establishing a source format for the encoded audio signal based on the bitrate; reformatting the encoded audio signal with a pre-selected pattern to generate a packet, wherein a capacity of the packet is based on the source format. And, in various other aspects, the disclosure provides for EVS decoding, including obtaining a data rate associated with a packet; discarding one or more pre-selected patterns from the packet to recover an encoded audio signal based on the data rate; and decoding the encoded audio signal to generate a decoded audio signal. |

1. A method for Enhanced Voice Services (EVS) encoding, comprising:
encoding an audio signal to obtain an encoded audio signal and a bitrate associated with the encoded audio signal; establishing a source format for the encoded audio signal based on the bitrate; and reformatting the encoded audio signal with a pre-selected pattern to generate a packet, wherein a capacity of the packet is based on the source format. |
