Hi,
As we discussed, I will create simple Roku channel with category screen, category items(videos) screen(Grid) and video player with pre-roll and post-roll ad support.
All images will be provided by you exact size required for roku that would be around 15 images like 2 splash screen(HD 1280x720, SD 720x480), hangover(HD 1280x110, SD 720x75), icon, web channel icon, ect. I will send you exact size required on Monday. These images are different size of your channel/app logo.
Thanks
