碩士 === 國立中正大學 === 電機工程所 === 97 === Under the trend of digitization, consumer electronic products take over information products to play a major role in market, especially digital TV. The subject of this dissertation is focused on digital TV broadcasting through 802.11 uni-casting. By employing the Wireless Local Area Network (WLAN) technique to communicate two devices, transport streams from the digital TV receiver are packed and transmitted to a computer through an 802.11 Access Point (AP) to accomplish uni-cast. Such a uni-cast is successfully conducted by implementing a Printed Circuit Board (PCB) that includes a LFEC3E Field Programmable Gate Array (FPGA) chip, an RTL8201BL Ethernet chip and corresponding electronic components. To effectively link our PCB and a computer, adequate handshaking mechanism is established. This computer receives broadcast packages and recovers transport streams. Additionally, it uses the package cache software, like winpcap, to store these transport streams, and then utilizes a media player to demonstrate digital TV programs. On the other hand, we also successfully developed another PCB that directly converts packets to transport streams. Here, two approaches are adopted to effectively realize this conversion. Notably, this work achievement can be beneficial to various digital-home applications.
