Introduction

The high-definition (HD) video standard has been developed as the successor to the analog, standard definition (SD) video, which (in the United States) dates back to the first proposal by the National Television System Committee (NTSC) in 1941. The HD standard has been developed by the Advanced Television Systems Committee (ATSC) and was approved in 1995. The ATSC standard encompasses an all-digital system and was developed by a Grand Alliance of several companies. Even though the ATSC standard supports eighteen different formats, we are restricting our discussion here to the ones that provide the most improvement in picture quality over NTSC. The two best-known HD formats are 1080i (1920 × 1080, 60 fields per second interlaced) and 720p (1280 × 720, 60 frames per second progressive), compared with 480i for SD.
