TV and radio advertisement detection (Phase 1 application)

目标是利用CRIM开发的电视和广播广告检测技术来开发广告检测产品和服务的原型。这些产品和服务具有非常广泛的适用性。例如，它们可以被电视台用来监测广告和索引广播，被CRTC用来监测广告的合规性，被广告公司和其他企业用来监测他们在电视和广播中播放的广告。我们开发了广告检测系统，可以准确地监测特定的广告，只使用音频。它还可以检测任意广告，召回率超过96%，准确率超过92%。同样的算法也可以用来检测互联网上点对点传输中受版权保护的音频（歌曲等）的复制。

The objective is to leverage the TV and Radio advertisement detection technology developed at CRIM to develop prototypes for advertisement detection products and services. These products and services have a very wide applicability. For example, they can be used by TV stations for monitoring ads and for indexing broadcasts, by CRTC for monitoring compliance of ads, by advertisement companies and other businesses for monitoring the airing of their ads on TV and radio broadcasts. We have developed advertisement detection system that accurately monitors specific ads using audio only. It can also detect arbitrary ads with over 96% recall and over 92% precision. The same algorithms can be used to detect copying of copyrighted audio (songs etc.) in peer-to-peer transfer over the internet.
