Description
Open-source hardware that turns NTSC composite video into color HDMI on a Tang Nano 4K. One FPGA I/O plus a passive R/C feedback network acts as a one-bit ADC; sync and color decoding drive three line buffers and 640x480 HDMI—no external ADC or decoder.

Could you build this?
No Requires deep electrical engineering, HDL programming (Verilog/VHDL), and low-level analog hardware circuit design for FPGA-based NTSC decoding and HDMI signal synthesis.
What it would actually take: Requires an FPGA development workflow using Gowin EDA toolchain with Verilog or VHDL to write hardware timing controllers, sync separators, and color subcarrier demodulators. It relies on hardware analog tricks (1-bit sigma-delta ADC using passive RC networks and LVDS/differential input buffers) to sample composite video at ~14.318 MHz (4x NTSC color burst). Expertise required includes high-speed digital circuit design, signal processing for color TV decoding (YIQ/YUV color spaces), line-buffer memory management, and TMDS video transmission timing for HDMI.
