基于FPGA的音频内容远程识别系统

FPGA-based Audio Content Remote Identification System

基于FPGA的音频内容远程识别系统利用互连网，通过对音频音调特征等进行采集到本地集中处理，实现了广播电视节目中播出广告的远程监测以及自动识别和分析统计。结果可以自动载入相关数据库。该系统主要为被广告公司提供投播信息、监播结果、决策依据。

The FPGA-based audio content identification system is used to present a comprehensive narration about industrial background of the apparatus and method to design and implement of it.This article focuses on an algorithm on character extraction of the television sound,and gives a new method of extracting the characteristics of audio data based on the Audio.The design of hardware in the system is also elaborated.
