This functionality greatly reduces the number of connections needed to setup a home theater, since a single connection between a TV/projector and a soundbar can deliver audio signals from all connected sources to the soundbar, and two, it consolidates and simplifies the type of connections used, since a user will only need to purchase HDMI cables to connect all their devices. Lastly, it allows the home theater to take advantage of the speed and bandwidth of the HDMI interface to support audio formats, such as Dolby Atmos, which other type of connections might not.
