Abstract: A karaoke system with built-in camera includes a decoder, a camera system, and a video selector. The decoder (e.g., a CDG decoder) receives data from a disc and provides a first video signal having graphics, e.g., for lyrics of a selected song. The camera system captures an image of a live scene and provides a second video signal. The video selector combines the first and second video signals to obtain a third video signal and can provide the first, second, or third video signal (e.g., based on user control) as an output video signal. A color eliminator can filter out a designated frequency (e.g., for a designated color such as blue) in the first video signal to provide a better output image for the third video signal. The decoder and camera system are synchronized with a common vertical timing signal and further use a common oscillator signal.

Abstract: A knitted fabric comprises a layer of hydrophillic yarn on one face of the fabric, a layer of hydrophobic yarn on the opposite face of the fabric. A pillar stitched, low density layer of yarn extends between and joins the hydrophillic and hydrophobic yarn layers.
