Title:
VOICE FREQUENCY DIVISION TRANSMISSION METHOD, SOURCE TERMINAL, PLAYBACK TERMINAL, SOURCE TERMINAL CIRCUIT AND PLAYBACK TERMINAL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2020/232631
Kind Code:
A1
Abstract:
The present application relates to the field of communications, especially relates to a voice frequency division transmission method, a source terminal, a playback terminal, a source terminal circuit and a playback terminal circuit; wherein the voice frequency division transmission method comprises: the source terminal encodes a first frequency band voice signal and a second frequency band voice signal; the source terminal marks frame synchronization information into the encoded first frequency band voice signal and the encoded second frequency band voice signal; and the source terminal sends the encoded first frequency band voice signal with the frame synchronization information and the encoded second frequency band voice signal with the frame synchronization information to the playback terminal through a first synchronization link and a second synchronization link respectively. According to the present application, the encoded first frequency band voice signal with the frame synchronization information and the encoded second frequency band voice signal with the frame synchronization information are sent to the playback terminal through the first synchronization link and the second synchronization link respectively, thereby solving the problem of sound quality degradation caused by the transmission bandwidth limitation and the problem of affecting the audio being played when improving the sound quality.
