  • Publication number: 20240098183
    Abstract: A marking method on image combined with sound signal, a terminal apparatus, and a server are provided. In the method, a first image is displayed. A selection command is detected. A target sound signal is embedded into a speech signal so as to generate a combined sound signal. The combined sound signal is transmitted. The selection command corresponds to a target region in the first image, and the selection command is generated selecting the target region through an input operation. The target sound signal corresponds to the target region of the selection command, and the speech signal is obtained by receiving sound. Accordingly, all attendants in the video conference are able to make makings on a shared screen.
