hd720p的意思
HD包含了720P. 简单来说，通常把物理分辨率达到720p以上的格式则称作为高清，英文表述High Definition，简称HD。 HD是指画面的垂直解析度是1080i、720p或1080p。1080i就是指解析度为1920*1080，采交错扫描，每秒呈现30个完整画面;
hd720p是指分辨率，越高越清楚，普通电脑显卡哪个都达不到的，换个好显卡500左右，还要显示器有高分辨率才行，720P准高清，也叫标清。
720P的意思
720P是美国电影电视工程师协会(SMPTE)制定的高等级高清数字电视的格式标准，有效显示格式为：1280×720。SMPTE(美国电影电视工程协会)将数字高清信号数字电视扫描线的不同分为1080P、1080I、720P(i是interlace,隔行的意思，p是Progressive,逐行的意思)。720P是一种在逐行扫描下达到1280×720的分辨率的显示格式。是数字电影成像技术和计算机技术的融合。
1080i和720p的区别
1080i和720p同是国际认可的数字高清晰度电视标准。原NTSC国家采用的是1080i/60Hz格式，与NTSC模拟电视场频相同。而欧洲以及中国等一些原PAL制国家则采用了1080i/50Hz模式，场频与PAL模拟电视相同。至于720p，则由于IT厂商更深的渗透到了电视行业而成为了一个可选的标准，目前开始在以光盘为载体的HDTV播放机领域拓展地盘。

hd版电影的意思
hd：High Definition
简单来说，通常把物理分辨率达到720p以上的格式则称作为高清，英文表述High Definition，简称HD。
HD高清是英文“High Definition”的中文缩写形式，意思是“高解析度[1] ”，共有四个含义：高清电视，高清设备，高清格式，高清电影。HD因为含有高解析度的意思，所以通常平板电脑的应用都会有HD的标识。
HD是指画面的垂直解析度是1080i、720p或1080p。1080i就是指解析度为1920*1080，采交错扫描，每秒呈现30个完整画面;720p就是指解析度达1280*720，采循序扫描，每秒呈现60个完整画面;1080p就是指解析度达1920*1080，采逐行扫描，每秒呈现60个完整画面。不过市面上薄面电视的解析度应不仅止于上述这些款式，只要显示萤幕的解析度>=1280*720即可以列为HD等级。
通常把物理分辨率达到720p以上的格式则称作为高清，英文表述High Definition，简称HD。所谓全高清(Full HD)，是指物理分辨率高达1920×1080逐行扫描，即1080p，是较高级的高清规格。
