為了解決hdmi擷取卡的問題，作者蔡智宇 這樣論述：

Numerous interfaces such as the intelligent software architecture and ELSA have been developed throughout the history of computer uses. In recent decades, peripheral component interconnect (PCI) and Peripheral Component Interconnect Express (PCI-E or PCIe) have been used frequently. PCIe is com

puter system bus, that operates according to the PCI coding concept and communication standards, and is based on the relatively fast communication serial system. Because PCIe is based on the PCI system, only the hardware layer requires modification the software that enables the PCI system to transfo

rm into PCIe does not require modification. PCIe can more quickly replace almost all existing internal buses, including Accelerated Graphics Port (AGP) and PCI. In this study, PCIe cards for High Definition Multimedia (HDMI) and Serial Digital Interface (SDI) were developed, and the SDI To PCIe card

was combined with a real-time multiple-license plate character recognition system. In Chapter 1 of this study, the major functions and features of the PCIe image capture card, and the system architecture are introduced. The real-time image, the resolution of which was 720p, was captured using a

camera and transmitted to a computer. The image information was obtained from the PCIe card, which was inserted into the computer. Finally, the image information was processed by the software interface system and the result was exported. Chapter 2 presents the specifications of the PCIe card and

used it to achieve the development goals of this study. Furthermore, the functional requirements of the HDMI, and SDI to PCIe, the circuit layout and the finished print circuit board, the installation of the PCIe windriver interface, and the distribution of the PCIe are described. In addition, devel

opment of the Graphical User Interface (GUI) are discussed. Chapter 3 with the real-time multiple-license plate character recognition system. The real-time license plate character recognition procedure was executed using the software interface and the results are presented in this chapter. After

processing was conducted using these procedures, a license plate character recognition system was established and its applications were determined. In Chapter 4, the development of the PCIe card and software interface is described. The results of the license plate character segmentation and licen

se plate character recognition are discussed. Chapter 5 provides a conclusion and recommendations for future research.
