As Lucas mentioned, your objective isn't clear. From what I think you mean is, you need to display video & banners on your mobile app.
If that's the case, is fairly easy to do with AdMob. For iOS, iAds also does the trick. In AdMob these videos are called interstitial. However, these are not the only services offering this type of advertising, there are many other, most of them -though- are native SDK to be embedded within your app. Using them on HTML is tricky, if it's ever possible!
By the same token, I would think, that since you're using HTML, is just a matter of finding the right ad platform and code that provides you the interstitial experience.
