Idea HN: QR inside video for ad's

USE CASES: 1. SOCIAL:you are watching tv with friends ad is shown,u might want to know more about product/buy it.You just need to click with qr app. 2. CROWD: You are at times square(or a place like that!) ad is shown u want to buy it.You can buy it/know it instantly. 3. NO_CABLE:You are watching ad in a medium which does not have two way connection. ADVANTAGE FOR AD COMPANIES: 1. They can catch/track you where they cannot in general track. 2. They have something measurable 3. They connect with you instantaneously. IDEA: Idea is to create a simple platform where ad companies will provide the link where they expect the user to land or create a page for their brand on the site and upload their video.QR would be generated based on the link and encoded in a video.All the traffic will go through our platform and would provide rich analytics. NEED UR INPUTS: 1.Is this a viable idea? 2. Are there already companies that do it(i googled it couldn't find anything substantial) 3. what do u think? should i try working on this criticisism is welcome :)
