1255614____ _ V. INSTRUCTION DESCRIPTION (1) _ [Technical Field of the Invention] ^ The present invention relates to an audio-visual playback system, and more particularly to a spear-proof, J-use virtual video zone module (virtual audio / Video driver modu 1 e) to control the wireless audio and video system of the remote entity playback device. v [Prior Art] With the continuous expansion of the information and computer market, the personal computer (PC) has become the standard equipment for performing work and entertainment, driven by the trend of light, short, versatile and fast. With the integration of technology and the development of peripheral devices, the DVD multi-channel home theater playback system, which is based on the personal _> computer platform, continues to enhance the market and service range. In addition, in recent years, computer games on personal computers have begun to add 3D positioning sound effects, so that the original attractive game is more attractive to listen to the ability to listen to the sound, in addition to the popularity of DVD ROM, most of the personal electricity month All have been equipped with the ability to play DVDs, multi-channel movies also let the sound of personal computers into the multi-channel system. With the current computing power of the central processing unit (CPU), it can be played smoothly. D V D software (software), while providing audio field output of AC-3 5.1. • AC-3's sound is divided into six channels: left front, right front, left rear, right rear, center position speaker, and subwoofer. In addition, in the four-channel system of the personal computer, the industry has designed the specifications of the 4. 1 D speaker, that is, the four-channel plus a subwoofer. Therefore, the AC-3's subwoofer data uses this architecture to add the bass component to the two flavors of the front channel.

Because ‘, after 1999, the high-end PC I sound card is almost all four-channel sound effects for the lock sales focus, but the price-oriented motherboard is the hope to balance the price and function. In addition, due to the obvious, and the recording DVD will dominate the key to IT production, the Internet also seems to be an online game or film or movie 'modern or future pictures, multi-person situation. Theater. Digital consumption In the future of the information 3 is the IT production for people to download songs if only people songs or , and . Therefore, the player can lose the image of the partner, the movie picture, etc. It can be played by a single computer. Because when there are many friends who want to have a movie together, it often happens that the computer screen is too small and there is no trend that the video and consumable products have the same performance. Today, shopping, playing songs and pictures can not satisfy the sharing. Under the circumstance, it can be dialed as if it were a cinema-like link. It has become the main player from the multi-media electronic product market, U Ying, various integrated video/sound exhibitions. And to improve the important part of the digital home. The manufacturer provides a kind of (Digital Media terminal connected to an electric IT industry, such as the digital entertainment application of the entertainment system in the network, such as the network download is too small and the law meets the class through the network Adapter) Please refer to Figure 1 for a household electricity. It is a schematic diagram of a traditional multimedia player (Digita 1 M edia A dap ΐ er) system. In this system, music and wireless network server software must be installed on the personal computer 2 0 2 or notebook computer.
