A few screens from a design exploration in which we asked, "What if we were not restricted by having to show the small video window (aka the PIG) in the upper left corner of the screen?"
Here, full screen video is pushed to the background, and we can maintain our immersive UI while never taking up 100% of the screen. Instead, a larger percentage of the video is incrementally covered the further you dive into learning about content. The Info Screen almost covers the screen entirely, assuming you're intention is to switch to a new piece of content. Meanwhile, the Mini Guide lets you see what's coming on next without interrupting what you're currently watching.
