Patent number: 8339914Abstract: Provided is a digital broadcast receiver capable of displaying a message, a list of titles of contents or the like together with a viewing screen without interrupting viewing of contents. The digital broadcast receiver includes a controller 25 configured to determine whether an optical disc inserted into the receiver is a read-only optical disc or a recordable optical disc and also to control a display screen. Upon insertion of an optical disc, the controller 25 causes a display screen including a first display area and a second display area to be displayed, the first display area displaying digital broadcast or external input contents, the second display area displaying a message indicating that the optical disc is being prepared. In a case where the optical disc is a read-only optical disc, the controller 25 causes only a playback screen of contents recorded in the optical disc to be displayed upon completion of the preparation of the optical disc.Type: GrantFiled: September 24, 2009Date of Patent: December 25, 2012Assignee: Sharp Kabushiki KaishaInventor: Toru Hirota

Patent number: 8296809Abstract: Where an instruction for a scheduled recording has been received from a remoter controller, a control unit starts the processing for display control (step S1). When the time has reached a predetermined period of time counted by a timer, for example, two minutes, before the start of the scheduled recording (step S2), the control unit determines whether or not a display unit currently displays two or more screen, and if the display unit is displaying two or more screens, the processing proceeds to step S4, and before the time for starting the scheduled recording, the controls unit makes a screen other than the screen for a program scheduled to be recorded disappear, that is, one of the screens, which displays a channel not selected for a scheduled recording, remain, and makes one screen in a multi-screen go into non-display. For example, on a TV screen, the display of a program on a BS channel for which a recording is scheduled disappears, and only the remaining BS display is provided.Type: GrantFiled: May 14, 2007Date of Patent: October 23, 2012Assignee: Sharp Kabushiki KaishaInventor: Toru Hirota
