Abstract

A method for controlling the capture of multimedia content, the method comprising: capturing, by a device, the multimedia content, the multimedia content including at least an audio signal and a video signal; obtaining control information based on at least one of the audio signal or the video signal ; controlling the preprocessing of the audio signal based on the control information obtained from the video signal; and / or controlling the preprocessing of the video signal based on obtaining the control information from the audio signal.

Description

Background technique [0001] Multimedia capture capability has become a common feature in portable devices. Multimedia calls between two or more check-in staff may include simultaneous transmission of both audio and video signals. On the other hand, many people tend to record or capture audio and video content at events they are participating in, such as concerts or sports events. [0002] Background noise challenges the audio coding and overall quality of experience in mobile multimedia communications. Multimedia terminals are often used in environments with high background noise levels, making multimedia capture vulnerable to background noise. In order to improve audio quality, multimedia terminals usually apply noise suppression (also known as noise cancellation) as a preprocessing step before the speech signal undergoes audio coding. Noise suppression can never completely distinguish between speech and background noise, and therefore noise suppression is usually designed to ...
