Abstract
In this paper, based on the FPGA and with a video dedicated A / D converter chip, LVDS coding chip, the design and implementation of a SD(standard-definition) analog video signals to HD(high-definition) digital video signal converter. First, input SD analog video into digital video signals meet the ITU-BT656 standard. Then use the FPGA with the video processing chip and DDR do some corresponding processing to achieve high-definition digital video output. After the actual test, the converter output signal of the image quality is well, meets the design requirements, and to verify the effectiveness of the program.
Highlights
With the increasingly and wide range applications of high-definition video, a large number of high-definition video equipment have emerged, accompanied DVI, HDMI, HD-SDI, LVDS and other emerging high-definition video interface
The market still has a lot of standard definition video capture equipment, such as PAL and NTSC format CCD camera. but new products of the video display devices are more of a digital high-definition input-based,such as LCD and LED monitor
It can be seen from the figure that the system mainly composed of the system by the video A/D converter module, the video signal processing modules and video serial output modules
Summary
With the increasingly and wide range applications of high-definition video, a large number of high-definition video equipment have emerged, accompanied DVI, HDMI, HD-SDI, LVDS and other emerging high-definition video interface. The market still has a lot of standard definition video capture equipment, such as PAL and NTSC format CCD camera. But new products of the video display devices are more of a digital high-definition input-based,such as LCD and LED monitor. How to make high-definition digital display device to match the analog standard definition video capture equipment and interconnection between a variety of interfaces, has become a problem of the modern video applications. This paper against the problem of not compatible in analog standard definition video capture equipments and digital high-definition video display devices, in industrial detecting field, so that achieve the standard definition analog video in real time and high-quality serial transmission, and display image clearly in digital high-definition monitor
