A Video signal which has the luminance component and color component separated to provide better image quality. Refers to images that consist of three independent signals: Y (luminance signal), Pb and Pr (color difference signals).

Video signals that have the video brightness signals and color signals mixed together. The type of signals commonly used by household video equipment (NTSC, PAL, and SECAM formats). The carrier signal Y (luminance signal) and chroma (color) signal that are contained in the color bar are overlapped to form a single signal.

However, the projector may not be able to project images protected with updated or revised versions of HDCP encryption.

An abbreviation for High-Definition Television that refers to high-definition systems which satisfy the following conditions.

•Vertical resolution of 720p or 1080i or greater (p = Progressiveg, i = Interlaceg)

•Screen Aspect Ratiog of 16:9

•Dolby Digitalgaudio reception and playback (or output)
