100Hz TV???


Recommended Posts


Hi Shahriar,
Actually TV pictures are interlaced, so each complete picture is broadcast at 25 pictures per second. Interlacing causes each individual line to flicker at 25 Hz so a sophistocated TV stores each picture in a digital memory then displays it non-interlaced which is called progressive scanning, or with doubled number of horizontal lines, or at any scanned frequency they want. The pictures are duplicated when they are scanned on the screen faster than they are received.
