摘要
高清晰度数字电视(HDTV)技术源之于数字电视(DTV)技术,HDTV技术和DTV技术都是采用数字信号,而HDTV技术则属于DTV的最高标准,拥有最佳的视频、音频效果。基于此,首先简单介绍了HDTV的定义;然后,详细论述了HDTV的各种显示技术,分别是:1080i(隔行扫描,清晰度1920×1080)、720p(逐行扫描,清晰度1280×720)和1080p(逐行扫描,清晰度1920×1080,),以及各种显示技术之间的联系与区别;最后,总结全文使读者正确认识和理解HDTV及其相关技术,概括得出有利于HDTV发展的结论。
HDTV technology originates from DTV technology. Both of them adopt digital signal, but HDTV technology has the highest standard with the best effect of video and audio than DTV technology. Firstly, it introduces the definition of HDTV briefly. Seeondly, it discusses the various HDTV display technique which are 1080i （interlaced, 1920 × 1080）, 720p （progressive, 1280 × 720） 1080p （progressive, 1920 × 1080）, and the relation and difference among them. Lastly, it makes a summary of the paper so that the user can make a correct recognizing and understanding to the HDTV and its related technology, also make some generalizations that are conductive to the development of H DTV.
