Publication number: 20080034398Abstract: A broadcast receiving apparatus includes a tuner unit, a display unit on which a program picture is displayed, an input unit including multiple channel operational buttons, and a control unit that controls these units in a centralized manner. When any of the channel operational buttons is touched, the input unit generates a first operational signal. When the channel operational button is depressed, the input unit generates a second operational signal. When the control unit detects the first operational signal during display of the program picture on the display unit, the control unit displays, on the display unit, program information signified by the first operational signal together with the program picture being displayed. When the control unit detects the second operational signal after detecting the first operational signal, the control unit switches the program picture being displayed to a program picture signified by the second operational signal.Type: ApplicationFiled: June 29, 2007Publication date: February 7, 2008Inventors: Maki FURUI, Toshiyuki Moriya, Tsuguo Itagaki, Sergio Paolantonio
