USB Wireless Connector Design And Implementation

With the advances in information technology and manufacturing process innovation, domestic digital equipment upgrades constantly. Today, digital television has also been a USB interface with the host side, and it can decode video files,so it can move the film up to the TV broadcast with the USB storage devices,such as audio and video files, and this makes more flexible to people that it provides a more convenient life. Because most audio and video files come from the network, if you want to play with the TV, you need to download the file to USB devices, and then television can play it.This procedure is subject to the USB device's capacity.In addition, the long download time also make users feel more irritable. Therefore, people need a high-speed, real-time online viewing experience. Based on this background, this design which named USB wireless connector can solve this problem. It was installed in the digital TV USB interface with wireless access to the Internet, high-speed connectivity networks for online video, and real-time broadcast on local television.This design uses a wireless network technology,it simulates network video files into the data which does not occupy space in the file list, stored in the linux system dev/ mtdblock node created above into a virtual FAT32 file system, it makes TV playing online video through the connector directly. This would have neither the USB capacity constraints nor the download time.This design describes the USB wireless connector design, including research programs,hardware,software structure,and compared with the same design; secondly,it completes a driver for the USB Gadget modifications and implementation can drive through the USB Gadget dev/mtdblock virtual nodes on the television for the disk,the disk storage of the video file name and other basic information,while a virtual FAT32 file system structure and analysis functions in detail design;then the wireless module of choice analysis, summarized why says it's better in the same design;Finally, test the speed of the connector to verify its feasibility. This design can be used with a USB interface which don't have wireless card TV,or with USB interface, VCD and other household appliances. Use the connector to the TV, users do not use USB flash drives and removable hard disk can store large video files online play movies and TV shows. Since then, the people can easily watch video, more real on television, it makes us more efficient, while saving network cable and other hardware equipment, the room neat also benefit. The design of the TV can easily play online video, is a triple play an important thrust will stimulate growth in business broadcasting.
