SMPTE 367M, also known as SMPTE D-11, is the [[SMPTE]] standard for HDCAM. The standard specifies [[video compression|compression]] of [[High-definition video|high-definition]] digital video. D11 source picture rates can be 24, 24/1.001, 25 or 30/1.001 frames per second [[progressive scan]], or 50 or 60/1.001 fields per second [[Interlaced video|interlaced]]; compression yields output bit rates ranging from 112 to 140&nbsp;Mbit/s. Each D11 source frame is composed of a [[Luminance (video)|luminance]] channel at 1920 x 1080 pixels and a [[chrominance]] channel at 960 x 1080 pixels. During compression, each frame's luminance channel is subsampled at 1440 x 1080, while the chrominance channel is subsampled at 480 x 1080, meaning 3:1:1 chroma subsampling.<ref>{{Cite web|url=https://www.tvyvideo.com/en/2006062219399/articles/technology-1/a-look-at-hdcam-sr.html|title=A look at HDCAM SR &#124; TVyVideo|website=www.tvyvideo.com}}</ref><ref>{{Cite book|url=https://books.google.com/books?id=0O8FpvOGul8C&dq=hdcam+140+3%3A1%3A1&pg=PT72|title=Digital Video Production Handbook|first=Pierre A.

Similar to MPEG IMX, the helical scan head drum is 80 mm in diameter. The helical tracks read by the video heads in the drum, are 22 microns wide. The video heads have a 15.25 degree [[azimuth recording|azimuth]]. Audio is also recorded on the helical tracks.<ref>{{Cite book|url=https://books.google.com/books?id=8YDOAwAAQBAJ&dq=dv+9000+rpm&pg=PA473|title=Broadcast Engineer's Reference Book|first=E. P.
