SDI/HDSDI Video Resolution Formats
An SDI/HDSDI signal can be one of several different resolutions. The SDI format may be
divided into either a 525 (720x486) @ 59.94i or a 625 (720x576) @ 50i signal resolution. These
are commonly called NTSC and PAL serial digital signals. Both resolutions employ 10 bit data
and a data clock rate of 270 Mb/s.
The HDSDI signal offers multiple resolutions in 720 or 1080 formats. The 720p signal format is
available at frame rates of 60, 59.94 or 50 Hz. The 1080 signal format is available in interlaced,
segmented or progressive scan formats at applicable frame rates of 30, 29.97, 25, 24, or 23.98
Hz. HDSDI employs 10 bit data and a data rate of 1.485 Gb/s.
