 # What is SyncTV?
-
 SyncTV is a program that allows you to watch movies and live broadcasts together remotely. It provides synchronized viewing, theater, and proxy features. With SyncTV, you can watch videos and live streams with your friends and family, no matter where they are.
 
 SyncTV's synchronized viewing feature ensures that everyone watching the video is at the same point in the video. This means that you can pause, rewind, or fast-forward the video, and everyone else will be synced to the same point. SyncTV also supports live streaming, so you can watch live events together in real-time.
