# Sixth Lichuang Electric Competition #bi4wms-Ambilight

* 1. Introduction to project functions

      The video atmosphere light control system controls the color of the TV frame corresponding to the light strip according to the color of the edge of the video signal screen, which creates a smooth transition effect visually, creating an atmosphere where the video content and the external environment are integrated.

    At present, Philips' Ambilight series TVs and Hue systems are mainly used commercially. Common open source projects are mostly installed through Raspberry Pi or PC, which requires complex and cumbersome software installation and requires many configuration steps and multiple module conversions on the hardware. To achieve this, the core principle is to capture the video stream through the network, the software analyzes and calculates the video stream, extracts the color information corresponding to the picture from the video stream, and finally controls the programmable lamp beads through the GPIO port or USB to serial port. The project is characterized by simple equipment, requiring only one controller, plug and play. The shortcomings of the former are obvious. The software and hardware configuration is complex. At the same time, the forward processing of the software system will inevitably lead to a lag in the color of the ambient light and the video signal. However, this system is implemented using FPGA, and there is no delay caused by the sequential execution of the software system. Therefore, There will be a more perfect video atmosphere scene experience.

*2. Project attributes

This project mainly adds wireless configuration parameter functions based on last year's project, and integrates various popular lighting effects on the market, making the project's usability and playability exponentially enhanced.

Design goals:

Simple hardware system and convenient software interaction

The main function:

Plug and play, no complex switching

The number of lamp beads can be configured according to the actual video screen size. One machine can be used for multiple purposes.

Supports a variety of popular lighting effects
