When you connect a DLNA-certified receiver to your home network, you can stream content like digital music files and photos from other DLNA-compatible devices and computers on your network.

Home theater receivers and preamp/processors with this feature can convert video signals coming in via component video jacks to a different form of video connection for output to your TV. Note that converting the signal from one connection type to another doesn't necessarily mean an improvement in picture quality or resolution - some receivers make the picture look better, while others merely convert the signal for hookup convenience
