Using a Home Entertainment Control Centre, gives you lots of additional audio and video inputs, so you can connect several different source devices (eg: DVD player, VCR, BluRay player, video game consoles, etc) to the switch box, and then connect the switch box to your TV. Then you can easily switch between your devices, either with the remote control or with the buttons on the switch box! No need to struggle behind your TV to disconnect and reconnect cables to get the right device working!
