Abstract:
1. A multimedia communication system, comprising: a transmitting end of the system comprising at least two sound picking up devices, an image capturing device, and a processor; a receiving end of the system comprises at least an image output device and a sound output device; and a correction module, wherein each of the at least two sound picking up devices is adapted to collect a sound signal of an acoustic source and send the collected sound signal to the processor; wherein the processor is adapted to receive multiple sound signals sent from the at least two sound picking up devices, to obtain location information of the acoustic source corresponding to an initial position of a lens in the image capturing device according to the sound signals, and to send the location information to the correction model; wherein the image capturing device is adapted to collect an image signal, to obtain information of variation of the lens, and to send the collected image signal and information of variation of the lens with respect to the initial position of the lens to the correction module; wherein the correction module is adapted to obtain current location information of the acoustic information according to the location information of the acoustic source and the information of variation of the lens, and to determine an orientation of sound of the acoustic source according to the current location information of the acoustic source; and wherein the receiving end is adapted to play the orientation of the sound of the acoustic source according to the determined orientation, so that the orientation of the sound signals of the acoustic source being played at the receiving end matches the position of the acoustic source in a picture being displayed.
