## Title
Network voice and video communication system and method

## Abstract

A network voice and video communication system for communicating with remote computer users via at least two chat applications. The network voice and video communication system captures voice and image data, acquires voice and image data, and stores voice and image data. The network voice and video communication system further receives transmission instructions from the at least two chat applications and transmits the voice and image data to the at least two chat applications. The at least two chat applications simultaneously transmits the voice and image data to corresponding network addresses of the remote computer users.

## Background
BACKGROUND
1. Technical Field
The present disclosure relates to voice and video communication, and more particularly to a network voice and video communication system and method.
2. Description of Related Art
Generally, a network camera providing network voice and video communication to a computer can only be employed by a single application. For example, the camera cannot be employed by Microsoft service network (MSN) Messenger and SKYPE at the same time, limiting effectiveness of the system.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a block diagram of an exemplary embodiment of a network voice and video communication system.
FIG. 2 is a flowchart of an exemplary embodiment of a network voice and video communication method.



DETAILED DESCRIPTION
Referring to FIG. 1, an exemplary embodiment of a network voice and video communication system 10 includes a voice and image capture module 100, a data acquisition module 200, a storage module 300, a transmission module 400, and a multi-application module 500. The network voice and video communication system 10 is configured for communication of a computer user 20 and remote computer users 30. The computer user 20 and the remote computer users 30 may connect to the network voice and video communication system via a communication network, such as the Internet or an intranet.
The voice and image capture module 100 is configured for capturing voice and images of the computer user 20, and can include a network camera and/or a network telephone, or a microphone. The network camera captures image data for different chat applications such as Microsoft service network (MSN) Messenger, SKYPE and others. The network telephone or microphone may capture corresponding voice data.
The data acquisition module 200 acquires voice and image data from the voice and image capture module 100. The voice and image data may include pixels, color, and/or audio frequencies of the voice and image data.
The storage module 300 temporarily stores the voice and image data acquired by the data acquisition module 200, and may be a random access memory (RAM).
The transmission module 400 receives transmission instructions from the multi-application module 500 to select the voice and image data from the storage module 300 and transmit the voice and image data to the multi-application module 500. The transmission module 400 may be a driver program. After receiving the transmission instructions, the transmission module 400 transmits the voice and image data from the storage module 300 to the multi-application module 500.
The multi-application module 500 includes at least two chat applications, such as SKYPE and MSN Messenger. The multi-application module 500 sends the transmission instructions to the transmission module 400 and receives the voice and image data therefrom, then transmits the voice and image data to corresponding network addresses (e.g., Internet protocol addresses) of remote computer users 30 on the network via the at least two chat applications simultaneously.
Alternatively, the voice and image capture module 100 may include a screen capture capability and/or a network telephone or microphone. Current display and audio output are thus available simultaneously via different chat applications.
Referring to FIG. 2, a network voice and video communication method is provided, which includes the following blocks.
In block S1, the voice and image module 100 captures voice and images of the remote computer user 30.
In block S2, the data acquisition module 200 acquires voice and image data of the captured voice and images from the voice and image capture module 100.
In block S3, the storage module 300 temporarily stores the voice and image data from the data acquisition module 200.
In block S4, the multi-application module 500 sends transmission instructions to the transmission module 400.
In block S5, the transmission module 400 receives the voice and image data from the storage module 300 according to the transmission instructions from the multi-application module 500, and transmits the voice and image data to the multi-application module 500.
In block S6, the multi-application module 500 transmits the voice and image data to the corresponding network addresses of the remote computer users 30.
It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
