High-definition video - online puzzles

High- definition video is video of higher resolution and quality than standard- definition. While there is no standardized meaning for high- definition, generally any video image with considerably more than 480 vertical lines (North America ) or 576 vertical lines ( Europe ) is considered high- definition. 480 scan lines is generally the minimum even though the majority of systems greatly exceed that. Images of standard resolution captured at rates faster than normal (60 frames/ second North America, 50 fps Europe ), by a high-speed camera may be considered high- definition in some contexts. Some television series shot on high- definition video are made to look as if they have been shot on film, a technique which is often known as filmizing.
