The multi-directional antenna has a variable amplifier which can be controlled a gain from the TV broadcast signal receiver and amplifies a received TV broadcast signal. The TV broadcast signal receiver detects a level of a TV broadcast signal outputted from the multi-directional antenna, and controls the gain of the variable amplifier corresponding to the detected level of the TV broadcast signal.Type: GrantFiled: January 17, 2006Date of Patent: March 16, 2010Assignee: Funai Electric Co., Ltd.Inventor: Mayumi Kaneko

Publication number: 20090310027Abstract: Systems and methods for adjusting the relative timing of audio and video signals of a video game responsive to a lag differential between an audio system and a video system connected to a game platform are described. In one embodiment, a method includes determining, by a game platform, a difference between an audio lag of an audio system connected to the game platform and a video lag of a video system connected to the game platform. The game platform may then transmit an audio signal and a video signal, wherein the relative timing of the audio signal to the video signal is reflective of the determined difference. The difference between the audio lag and video lag may be measured directly, or the audio and video lag may each be measured separately.Type: ApplicationFiled: June 16, 2008Publication date: December 17, 2009Inventor: James Fleming

Patent number: 7573536Abstract: A method for controlling a device for the distribution and processing of video signals is proposed. The device has a number of inputs and outputs. Signal processing stages for processing the input signals can optionally be switched into the signal paths. The method according to the invention comprises the following steps: input signals are represented on a display with an input symbol. When common properties are present, the relevant input sources are assigned input symbols which have a common color property and/or graphical property. The relations between a specific input symbol and the assigned input signal and the relevant input are stored. An output of the device is assigned an output symbol, which represents the desired properties of the output signal in the same way as the input symbols represent the properties of the input signals. Finally, an output symbol is assigned to an input symbol, whereupon the relevant input is connected to the relevant output.Type: GrantFiled: March 22, 2004Date of Patent: August 11, 2009Assignee: Thomson LicensingInventor: Arnd Paulsen
