HD technology and DVR technology have both served to transform and greatly enhance the way people watch TV. High-definition signals require a high-definition television or computer monitor in order to be viewed. High-definition video has an aspect ratio of 16:9 .The aspect ratio of regular widescreen film shot today is typically 1.85:1.Standard-definition television (SDTV) has a 4:3 aspect ratio, although in recent years many broadcasters have transmitted programs "squeezed" horizontally in 16:9 anamorphic format, in hopes that the viewer has a 16:9 set which stretches the image out to normal-looking proportions or a set which "squishes" the image vertically to present a "letterbox" view of the image, again with correct proportions. High-definition image sources include terrestrial broadcast, direct broadcast satellite, digital cable, IPTV, Blu-ray video disc (BD) and internet downloads. Sony's PlayStation 3 has extensive HD compatibility because of the Blu-ray platform so does Microsoft's Xbox 360 with the addition of Netflix streaming capabilities and the Zune marketplace where users can rent or purchase digital HD content. ...
... The HD capabilities of the consoles has influenced some developers to port games from past consoles onto the PS3 and 360 often with remastered graphics. High-definition video is video of higher resolution than is standard. While there is no specific meaning for high-definition, generally any video image with more than 480 horizontal lines (North America) or 570 lines (Europe) is considered high-definition. 720 scan lines is generally the minimum even though many 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. Additionally, non-interlaced video (also called progressive scan) is sometimes considered high resolution, even at standard resolution and frame rates.
