FPGA-HDMI1080p video atmosphere light controller

Brief Introduction

• The FPGA-based 1080p video atmosphere light controller analyzes the HDMI video signal, analyzes the color signal of the edge of the picture, controls the color of the corresponding light strips around the TV, and achieves a smooth transition effect visually.

Project Introduction

* 1. Describe the project details

FPGA is used for video signal analysis and processing, WS2812 light strip driver, and open source microcontroller IP core is integrated into FPGA for user interactive settings and parameter adjustment.

* 2. Describe the challenges faced by the project and the problems it solves

Currently, only Philips' Ambilight series TVs are commercially available. Common open source projects require the installation of complex and cumbersome software and configuration steps through Raspberry Pi or PC, and multiple module conversions, etc. This project only requires an FPGA as the core controller, combined with a one-to-two HDMI distributor, which supports up to 4056 lamp beads, and can be used on TVs over 100 inches without any pressure.

* 3. Describe the key points involved in the hardware and software parts of the project

Hardware

• 1) FPGA is connected to an external HDMI video capture chip to capture and analyze video content
• 2) FPGA interacts with the user through the serial port to set parameters, etc.
• 3) FPGA controls the WS2812 light strip to display the color according to the edge of the picture

Software

• 1) FPGA reads each frame of video and smoothly analyzes the edge pixel color
• 2) FPGA controls the WS2812 light strip to display the corresponding edge color of the screen based on the pixels calculated by analysis
• 3) FPGA user interaction, parameter setting, such as background wall color compensation, video signal delay response

One is too few, we need at least 10 people before we can start.
