Abstract: Input sources to a display, such as a television, are depicted with a first indicator if active, such as active with a signal having visual information, and are depicted with a second indicator if inactive, such as lacking an active signal. A selection module allows a user of the display to select an active source but precludes selection of an inactive source. For instance, a user is allowed to select highlighted input sources that are active but not allowed to select grayed out input sources that are inactive. An override allows the user to present all input sources with the first indicator, whether or not the input sources are active.

Abstract: Audiovisual settings for audiovisual display devices are automatically applied based on a user identification input at the audiovisual display device. A display settings module associated with the audiovisual device applies locally cached settings if available or retrieves global settings for the user from a network location. A settings match engine determines audiovisual setting for the user based on the audiovisual device type characteristics and the user's globally stored audiovisual settings. Automatically managed audiovisual settings include display picture settings, channel settings, localization settings, audio settings and lockout settings.

Abstract: Systems and methods for presenting high definition display signals in secondary windows of a display are disclosed. In one embodiment, the aspect ratio of a high definition content secondary window is adjustable. The high definition content secondary window may be a PIP, POP, PBP or other window. Furthermore, the image within the high definition content secondary window may be scaled in a wide variety of manners such that the image shape within the window may also be adjustable. Thus, in one embodiment both the window shape and the image shape within the window may be adjustable. Furthermore, the input format of the content presented to the display may be one of a wide variety of formats. In a further embodiment, the secondary window shape and image shape may be adjustable for a plurality of different input formats.
