Abstract: A GUI (Graphical User Interface) device includes a function detecting circuit for detecting whether a plurality of functions is valid or invalid, a controller for changing a display style of icons corresponding to the functions and an icon corresponding to function groups based on the detection done by the function detecting circuit, an OSD (On Screen Display) creating circuit for following a command from the controller and creating icons corresponding to the functions and the icon corresponding to the function groups, and a display section for displaying the icons created by the OSD creating circuit. When the functions are valid, the controller displays icons corresponding to the respective functions on one-to-one basis, and when the functions are invalid, the controller displays a single icon representing a function group, to which the invalid function belongs, in a display style indicating invalidity.

Abstract: Provided is a television broadcast receiver which is further enhanced in the independency of the user application software from the hardware and can increase the development efficiency. The television broadcast receiver includes; a digital channel-selecting means; an analog channel-selecting means; a video signal processing means for processing a video signal from the digital channel-selecting means and a video signal from the analog channel-selecting means; a graphics OSD creating means for creating a graphics OSD signal; a text OSD creating means for creating a text OSD signal; and an RGB processing means for mixing an output of the video signal processing means, the graphics OSD signal, and the text OSD signal.
