what is difference between hd and full hd

To provide smooth and low bit-rate video streaming, Ultra high definition devices adopt the latest H.265/HEVC compression format.

4K UHD reaches approximate 8.29 megapixels resolution (3840x2160), while 8K UHD reaches approximate 33.18 megapixels (7680x4320). Ultra high definition also known as UHD/4K, this standard includes 4K UHD and 8K UHD. Full HD 1080P Logo Ultra High Definition (HD) Apparently, 1080p can ensure the high resolution, excellent image quality, it's widely used in high definition video surveillance systems. 1080p picture quality is better than 1080i. they have a great difference in image quality. The so-called full HD, refers to the physical resolution up to 1920x1080 (including 1080i and 1080p), i is the abbreviation of interlace, means interlace scan p is the abbreviation of progressive, means progressive scan. In video surveillance market, based on H.264 IP camera and network video recorder supports HD resolutions, typically reaches 720p, 1080p, even much higher resolution such as 3 megapixel, 5 megapixel. Meanwhile, the 16:9 video aspect ratio brings a broader vision. On image quality perspective, HD resolution is four times higher than traditional analog television resolution, image clarity, color reproduction are superior than traditional TV. Apparently, HDTV is the highest standard, its resolution reaches approximate 35mm wide-screen film level, it requires video and display equipment supports horizontal resolution reaches above 1000 television lines, resolution reaches 1920x1080.

Since different image quality and data bandwidth, making video signal divide into High Definition Television (HDTV), Standard Definition Television (SDTV), Low Definition Television (LDTV). About HD standard, internationally recognized two criteria: video vertical resolution higher than 720p or 1080i video aspect ratio is 16:9.įrom video quality, we can easily know the difference between 'HD' and 'SD'. 720p means the vertical resolution is 720 television lines with progressive scan. The physical resolution higher than 720p called as High Definition (HD). Standard definition refers to full D1 (720x576), that is SMPTE 259M standard. Specifically, that means resolution approximate 400 TV lines VCD, DVD, TV shows and other 'SD' video format. The so-called SD, is the physical resolution below 720p (1280x720) format. Compared with traditional CCTV video surveillance system, high definition means superior image quality. As video surveillance now adopting HDTV, we usually hear several resolution standards including SD, HD, Full HD, Ultra HD.

Over the past few years, driven by the consumer electronics market, HDTV LED/LCD television gradually replaces the traditional CRT television, HDTV technology achieve great success.
