A TV has a TV processor and a display presenting a map showing the topology of the home network of which the TV is a part. A user can manipulate the user input device to navigate around the map and cause content to be transmitted from a source component shown in the map to a sink component shown on the map. The map can change the appearance of component icons and/or paths between icons to provide visible indication of advantageous component and/or path selection for executing a user-desired task. Also, map information can be uploaded to an Internet server that can respond by sending back information pertaining to components represented on the map.
