What You Must Know About High Definition Cameras
High Definition industrial cameras have significantly higher resolution than the standard format cameras. HDTV (High Definition Television) technology was first introduced in the US through the 1990s by the Digital HDTV Grand Alliance. It consisted of entities like AT&T, General Instrument Corporation and Massachusetts Institute of Technology. The introduction of the HDTV format required specialized high definition cameras, cabling and tv monitors.
There are three HDTV standards which are currently defined by the International Telecommunication Union (ITU-R BT.709). They are 1080i (1,080 actively interlaced lines), 1080p (1,080 progressively scanned lines), and 720p (720 progressively scanned lines). All of those standards use a 16:9 aspect ratio. All current HDTV broadcasting standards are encompassed within the ATSC and DVB specifications.
The Advanced Television Systems Committee (ATSC) may be the group that developed the ATSC Standards for digital television in the United States, also adopted by Canada, Mexico and South Korea.
DVB, short for Digital Video Broadcasting, is a suite of internationally accepted open standards for digital television.
