Publication number: 20140016039Abstract: The present invention relates to electronic units, communication systems and methods, information processing terminals and methods, and information processing apparatuses and methods which allow easy and quick communications. When a link pin 21A is inserted into a VCR 3, the VCR 3 reads the pin ID stored in the RF tag of the link pin 21A, and reports the pin ID and the address to a management server 1. When the management server 1 has already obtained the pin ID of a link pin 21B read by a television receiver 5, the management server 1 determines whether the group ID included in the pin ID reported by the VCR 3 is the same as the group ID included in the pin ID reported by the television receiver 5. When the management server 1 determines that they are the same, the management server 1 connects the VCR 3 to the television receiver 5. The present invention can be applied to various types of information processing apparatuses connected to a network.Type: ApplicationFiled: September 12, 2013Publication date: January 16, 2014Applicant: SONY CORPORATIONInventors: Yuji AYATSUKA, Nobuyuki MATSUSHITA

Video display apparatus for shortened-delay processing of a video signal and video processing method
Patent number: 8593575Abstract: According to one embodiment, a video display apparatus includes a video processing module and a controller. The video processing module is configured to perform signal processing on a video signal to generate a display video signal, and to output the display video signal to a display module. The controller is configured to turn on or off short delay processing mode, and to control the video processing module so that a delay time of the display video signal from the video signal becomes approximately 12 to 17 ms at a minimum when the short delay processing mode is on.Type: GrantFiled: November 30, 2011Date of Patent: November 26, 2013Assignee: Kabushiki Kaisha ToshibaInventor: Kenichi Horikoshi -
Patent number: 8576343Abstract: According to one aspect, a mixed-signal tuner for analog and digital TV reception incorporates a demodulator for analog TV, employing various features for resolving limitations of the analog circuitry and for achieving compatibility with various global TV standards. Such features, which may be present in one or more embodiments, include the use of a variable sample rate in all digital clocks for frequency planning, and use of a microcontroller (MCU) to control various circuitry of the tuner.Type: GrantFiled: June 29, 2009Date of Patent: November 5, 2013Assignee: Silicon Laboratories Inc.Inventors: Alan Hendrickson, David Trager, Mitch Reid, Li Gao, John Khoury

Patent number: 8570435Abstract: A video processing method and a device thereof are described. The method includes the steps as follows. An input video signal is received, in which a single period of the input video signal has a plurality of first input frames and a plurality of second input frames. The input video signal is processed, so as to generate an output video signal, in which a single period of the output video signal has a plurality of first output frames and a plurality of second output frames, and an amount of the first output frames is the same as an amount of the second output frames. A sum of the amount of the first output frames and the amount of second output frames is an integer multiple of a sum of an amount of the first input frames and an amount of the second input frames.Type: GrantFiled: October 2, 2009Date of Patent: October 29, 2013Assignee: Realtek Semiconductor Corp.Inventors: Jin-Sheng Gong, Hsieh Chun-Hsing

Patent number: 8482674Abstract: A video production apparatus advantageously includes at least one embedded multi-previewer (14) that receives at least some of a plurality video signals generated by one or more elements in the switcher, such as a mix-effects engine (10). The multi-previewer generates an output signal which when displayed yields of mosaic of images, each representative of a respective input signal. In this way, an operator can observe, via a single video monitor, the status of multiple video signals, thus obviating the need for multiple device outputs, multiple monitors, and associated cabling.Type: GrantFiled: July 16, 2008Date of Patent: July 9, 2013Inventors: Bret Michael Jones, David Alan Casper

Patent number: 8477245Abstract: A television adapter includes first and second conversion circuits, a switch unit, and a high-definition multimedia interface (HDMI). The first conversion circuit includes a digital to analog (D/A) converter and a coupler. The second conversion circuit includes an analog to digital (A/D) converter and a decoupler. When the switch unit connects the first conversion circuit to the first HDMI, the D/A converter converts a first digital signal from the HDMI into a first analog form data. The coupler couples the first analog form data to a first alternating current (AC) voltage. When the switch unit connects the second conversion circuit to a second HDMI, the decoupler decouples and separates a second AC voltage into a second analog form data. The A/D converter converts the second analog form data into a second digital signal, and outputs the second digital signal to the second HDMI.Type: GrantFiled: April 10, 2012Date of Patent: July 2, 2013Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Chih-Huang Wu, Szu-Lun Huang
