Shahriar Posted January 21, 2006 Report Posted January 21, 2006 HiWhen I go to market, I see some modern TVs which is written on them: " 100Hz Scan "My question is when the Transmitter sends 50 Pictures per second, then How they show 100 Picture per second?ThanXShahriar Quote
audioguru Posted January 21, 2006 Report Posted January 21, 2006 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. Quote
