Q: WHAT IS NTSC AND PAL STANDARD?
A: NTSC is the video system or standard used in North America and most of South America. In NTSC, 30 frames are transmitted each second. Each frame is made up of 525 individual scan lines. PAL is the predominant video system or standard mostly used overseas. In PAL, 25 frames are transmitted each second. Each frame is made up of 625 individual scan lines. PAL: Afghanistan,Algeria,Argentina (N),Austria,Australia,Bangladesh,Belgium,Brazil (M),China,Denmark,Finland,Germany,Hong Kong, Iceland, India, Indonesia,Iraq, Ireland,Israel,Italy,Jordan,Kenya,Kuwait,Liberia,Malaysia,Netherlands,Nigeria,Norway,New Guinea,Pakistan,Singapore,South Africa,South W.

Q: What is S-Video ?
A: It's an analog video signal that carries video data as two separate signals: lumen (luminance) and chroma (color). This differs from composite video, which carries picture information as a single lower-quality signal, and component video, which carries picture information as three separate higher-quality signals. S-Video carries standard definition video (typically at 480i or 576i resolution), but does not carry audio on the same cable.
Q: What is YPbPr signals ?
A: YPbPr is a color space used in video electronics, in particular in reference to component video cables. YPbPr is the analog version of the YCBCR color space; the two are numerically equivalent, but YPBPR is designed for use in analog systems whereas YCBCR is intended for digital video. Y carries luma (brightness) and sync information. PB carries the difference between blue and luma (B − Y). PR carries the difference between red and luma (R − Y).
