 * Philips (TP Vision) saves an input's name from its Sources menu as "Name&TYPE", the type picking the icon there
 * ("Xbox&GAME_CONSOLE", "Ordinateur&COMPUTER"), and an unnamed port as the text "null". Shown as is, the Inputs
 * menu read "Xbox&GAME_CONSOLE · HDMI 1" and "null · HDMI 4". This gives "🎮 Xbox" and no name; the TV's own
 * setting is left as it is.
