Abstract: A vertical synchronization circuit for synchronizing multiple video streams using an input vertical sync signal. The circuit includes a digital phase lock loop circuit configured to generate an intermediate frequency signal based on the input vertical sync signal and an analog phase lock loop circuit configured to convert the intermediate frequency signal into a pixel clock. They system further includes a counter configured to generate output synchronization signals based on the pixel clock.

Abstract: Various embodiments are described herein for automatic gain control techniques that can be used by a universal television receiver that is capable of processing television channel signals broadcast according to a variety of analog and digital broadcast standards.

Abstract: An image pickup apparatus includes a camera body 1 including a monitor unit 11, a lens barrel 2 and a lens body 3 which include an image pickup optical system L, a rotary portion 8 provided between the camera body 1 and the lens body 3, and rotatably supporting the lens body 3 with respect to the camera body 1, absorption portions 12a and 12b attached to the camera body 1, and a cover portion 4 movably connected with respect to the camera body 1 and covering the absorption portions 12a and 12b.

Abstract: A display apparatus includes a receiver which receives a broadcasting signal, a display which displays an image based on the received broadcasting signal, a communication unit which communicates with a mobile device, and a controller which determines whether the mobile device interferes with at least one channel of a plurality of broadcasting channels received through the receiver, and controls the display to display a user interface (UI) indicates a user whether image noise has resulted from channel interference by the mobile device.

Abstract: In one aspect a transmission system with a transmitter which can be connected to a video source and a receiver linked to the transmitter via at least four circuit pairs, to which receiver a playback device can be connected is provided. Data is usually exchanged digitally between a graphics card in a personal computer and an LCD display module. The personal computer transmits a digital R, G, B video signal to the LCD display module via a special, so-called DVI (Digital Video Interface) cable. This DVI cable is also provided to transmit so-called DDC (Display Data Channel) data, which particularly comprises specification information of the LCD display module. A transmission system is proposed, which simplifies a connection of an LCD display module to a personal computer and with which the DVI cable can be dispensed with.
