1. Field of the Invention
The present invention relates to a network video device, and particularly to a multimedia network video device.
2. Prior Art
As development of communication technology, it seems that distance between people in different places gets shorter and shorter. When you want to contact a person far away from your place, you may traditionally use a telephone or a fax. However, you cannot see his or her face and action through the traditional manner.
To encounter the above problem, a video conference is provided through a network. People at different places can see and talk with each other through the video conference. Therefore, the video conference makes communication easy for people at different places, which improves communication efficiency and reduces communication cost.
However, since a conventional network video device is connected to the network in wire communication, the video conference can only be hold at some regular places such as at office or at home for connecting to the network. Therefore, you cannot contact people through the video conference when you are not at the regular places. So, it is not convenient to use the conventional network video device at some extent.
Furthermore, the conventional network video device has a single function of holding a video conference. However, since people need more and more digital products with different functions nowadays, it is usually inconvenient for a user to take with many digital products for providing the different functions. So, it is required a multifunctional product.
Accordingly, an object of the present invention is to provide a multimedia network video device, which is combined with a compact disc (CD) read device, a network video device and an LCD module, and uses one CPU to process multimedia audio and video (AV) data thereby expanding functions of the network video device, whereby the multimedia network video device is multifunctional.
Another object of the present invention is to provide a multimedia network video device, which has a function of a multimedia player but does not need to connect to an external CD-ROM, whereby the multimedia network video device is convenient to use and saves space.
Another object of the present invention is to provide a multimedia network video device, which is connected to a wireless network, thereby being portable and mobile.
Another object of the present invention is to provide a multimedia network video device, which is connected with an external AV signal generator, and plays external AV signals through a display device thereof, whereby the multimedia network video device is convenient to use.
Another object of the present invention is to provide a multimedia network video device, which is multifunctional thereby reducing cost relative to having the functions separately.
To achieve the above-mentioned objects, a multimedia network video device in accordance with the present invention includes a CPU, an I/O module connected to the CPU for transmitting data to or from CPU, a video capturing module for capturing video data and transmitting the video data to the CPU for processing, an audio capturing and playing module connected to the CPU for capturing and playing audio data, a function key module for controlling function status of the CPU, a video driving and displaying module for driving video data processed by the CPU and transmitting the video data to a display device thereof for playing, a CD read device for receiving a CD and reading data from the CD and then transmitting the data to the display device for playing, and a power supply module for providing power to the above modules. The CPU processes data transmitted from the above modules.
Other objects, advantages and novel features of the present invention will be drawn from the following detailed embodiment of the present invention with attached drawings, in which:

Referring to
When the multimedia network video device 26 is used to play CD, a CD playing function is selected through the function key module 18 and then the CD which may be a VCD or a DVD is inserted to the CD read device 22 for reading AV data. The AV data are transmitted to the CPU 10 for processing and then the processed AV data are transmitted to the display device 202 for display through the video driving and displaying module 20.
When the multimedia network video device 26 is used to play AV signals from an external signal generator, a function of playing external AV signals is selected through the function key module 18 and the external AV signal generator is connected to the AV transmission port 124. The AV signals from the external AV signal generator are transmitted to the CPU 10 for processing and then the processed AV signals are transmitted to the video driving and displaying module 20 for displaying through the display device 202.
As described above, the multimedia network video device of the present invention is combined with a CD read device, a network video device and an LCD module, uses one CPU to process multimedia AV data, is connected to a network through wireless communication, and is connected to an external AV signal generator whereby the multimedia network video device is multifunctional, portable, mobile and convenient to use.
It is understood that the invention may be embodied in other forms without departing from the spirit thereof. Thus, the present examples and embodiments are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein.
