A simulated live feed gives the appearance of a live stream. Though, in reality, a simulated live feed is nothing but the videos of the input MRSS feed(or whichever feed you select as the input for the simulated live feed) auto-playing on a loop.
During a Simulated Live play, whenever a new video is added to the input MRSS feed, the user will be taken back to the first video of the simulated live feed as soon as the app reads the new item. If no new item is added to the input MRSS feed, then the app will remember the spot in the simulated live feed till where the user had last seen the feed.
