FHD means Full HD, which is fully HD, and is called full high definition. Generally can achieve resolution 1920*1080. FHD means Full HD, when the chip source reaches 1080P definition, FHD LCD TV can complete performance. If you buy HD TV, SD TV, then even if the signal source is full HD, it can only display SD.

Scope: Generally used at home electricity (flat-screen TV), digital products, notebooks, similar digital cameras, MP5, MP4 and so on.

Another video that does not reach HD (<=1280*720) is SD (Standard Definition), General standard 4:3 is 640*480 (VGA), 16:9 is 848*480 (WVGA), PAL is 720* 576,NTSC is 720*480. Of course there are also "variants", such as 15:9 800*480 (WVGA).

Many cameras already have the ability to shoot FHD video. The general film is to use FHD after filming, after processing made. FHD has the following frame frequency: 1920*1080 60p (i) (NTSC) 1920*1080 30p (NTSC) 1920*1080 50p (i) (PAL) 1920*1080 25p (PAL) 1920*1080 24p (movie). 60p (i) and 50p (i) are also known as full HD progressive.

There is also a 4:3 screen ratio, the resolution of 1440*1080 and 960*540, the former also known as the 4:3 in the Full HD FHD, the latter is HD HD, which often appears in the camera. So we now see the news ah, generally not 640*480 shot, but the two kinds of shots.

The 1920*1080 pixel in the photo is 2M (million pixels) and a higher level is 3.5m,2560*1440 pixel. And now the highest video sharpness is just 1920*1080. Reason: 1. TV, camera and other reasons can no longer improve clarity. 2. Size. such as Canon SLR 1920*1080 p capacity can be as high as 330mb/min (MOV), Panasonic and Sony AVCHD format also has more than 100mb/min capacity, and MP4 also 100mb/min above the size.

Limited to this, the current size of the largest FHD format is 1920*1080 60/50p (i). Since the three resolutions of 1920*1080 and 1280*720 and 640*480 are doubly related, that is, (the size of the shot) 4:2:1, some cameras with high speed photographic capabilities can only be 1280*720 100fps (PAL) 640*480 200fps ( PAL) 1280*720 120fps (NTSC) 640*480 240fps (NTSC).

HD is the resolution or pixel is 1280*720 above the video, and currently capped for 1920*1080. In other words, 16:9 HD video has only two resolutions: 1280*720 (HD), 1920*1080 (FHD). HDTV is a high-definition TV 1280*720 above resolution. To view high-resolution pictures, video (resolution >=1280*720) on High-definition televisions (resolution >=1280*720), use HDMI connectors to connect televisions and computer or camera DVDs.
