 | HD Ready To appreciate just how good a high definition picture is, it helps to know how TVs, DVDs and VHS worked in the past. Until recently, there was only one type of broadcast format Standard definition - SD. With SD, the level of detail in the picture resolution is limited. SD has a resolution of 720 X 576, which means 576 horizontal lines of 720 pixels each. Pixels are the dots which make up a digital picture. The new HD formats boost resolution far beyond SD, giving your TV a level of clarity and detail that is absolutely breathtaking. |
