2008年3月24日 · I need to convert 50Hz 625 lines interlaced video frame to vga 640*480 at 60Hz or more. The solution that I find, it is to save all images to a memory. Then I can read it with another rate, but I think it is not a very good solution.

2016年8月6日 · Easy add-on TV tuner module for all VGA-based monitor or projector without coax input. Decoding RF coax signals from cable outlet, satellite box, RF modulator or CCTV surveillance camera system to sharp VGA pixels for display. 4 selectable video inputs: RF/Coax, RCA A/V, S-Video and VGA pass through.

A hardware software co-design for an FPGA based real time video processing system to convert video in standard PAL 576i format to standard video of VGA / SVGA format with little utilisation of resources is realised and evaluated.

2019年6月12日 · A novel RTVPS is designed using FPGA for efficient conversion of PAL to VGA, useful for rugged application with high bandwidth and little resource utilization. It can switch between multiple video input channels. Video output obtained is in real time and can display in VGA or SVGA format with character/text overlay.

2015年3月30日 · I am doing a project using TERASIC DE2 board to convert pal 720×576 to vga. I am using the adv7180 for pal adc and adv7123 for vga dac.

The SB-3860 Video To VGA system converter is designed to convert DVD or VCR Video, S-Video systems or computer VGA signal with Digital Signal Processing (DSP) then output through VGA format.

本文介绍的转换器用于计算机VGA信号转换为彩色电视机PAL和NTSC制式信号. 工作原理. 电路原理如附图所示。 该电路以模拟集成电路AD722为基础，AD722是可将RGB信号转换为NTSC/PAL信号的 编码器，产生与PAL或NTSC标准一致的、对应的亮度 (基带振幅)和彩色信号 (调幅和调相)，还可将亮度和彩色信号混合生成混合视频输出，所有输出可直接驱动标准75Ω端口的视频电缆，无需额外的放大器，该器件只需一组＋5V电源，而且无需外部延迟线或滤波器。 该转换器 …

Our Video Display Format Converters are board-level modules that convert signals between mutually incompatible video formats and standards. Different products exist for converting signals between PC VGA graphics, broadcast-quality NTSC, PAL, RS170, HDMI/DVI and STANAG 3350.
