Links and Sources: [1] CCIR476 Arduino library, Does anyone have any tips for using an Arduino to overlay a real-time data stream onto an NTSC video signal? My application is a downlink video system to be flown in large model rockets. With 'TheDotFactory' software I generated a character bitmap for a subset of the ASCII codes 32 - 126 used for regular text display. SDI signal generators typically cost anywhere from $350 to $2,000. So signal coming from eye phone jack to An Arduino NTSC/PAL video display shield with integrated framebuffer and composite video output. Once you can produce a PWM signal you just have to modulate it with whatever waveform you like. 84: Unlike the 640×480 image, both sync-pulses (HSYNC and VSYNC) are positive. The frequency range reaches form zero to 16 KHz with a resolution of a millionth part of one Hertz! Distortions can be kept less than one percent on frequencies up to 3 KHz. This one uses an AD9833 module and an Arduino Nano - that's all, not even a PCB. Any help appreciated. Figure 11: Finished signal generator \$\begingroup\$ People have generated PAL/NTSC video in software on PIC and Arduino, search Hackaday. You can optionally add an OLED display. To run the Test Pattern Generator, you'll need to download the ESP_8_BIT_composite library, uncompress the .
