Surely one of the biggest challenges facing publishers seeking to monetize their online video content is how to effectively use ads from a multitude of ad networks. These ad networks represent the largest pool of online video inventory.The problem is that there are a number of video ad networks and many have different formats. Moreover, there are a number of ad serving technology companies who help publisher. Most of not compatible. San Mateo-based Adap.tv, which started as a platform to deliver overlay ads, has changed course to provide a universal tool which allows publishers to integrate multiple advertising sources -- both network and internal inventory.A few months back, I interviewed CNET's Rafe Needleman who told me that there were just too many ad networks startups in in the online video space. I agree. Whether Adap.tv can bring uniformity to the industry remains to be seen, but it would be welcome.Here is my interview with Adap.tV CEO Amir Ashkinazi. Before forming Adap.tv, Amir was founder of CTO of Shopping.com which was sold to eBay. We caught up last week at Digital Hollywood.-- Andy Plesser
