SMPTE 259M

SMPTE 259M is a standard published by SMPTE which "... describes a 10-bit serial digital interface operating at 143/270/360 Mb/s." ^[1]

The goal of SMPTE 259M is to define a serial digital interface (based on a coaxial cable), called SDI or SD-SDI.

There are 4 bitrates defined, which are normally used to transfer the following standard video formats:

Variant	Bitrate	Display Aspect Ratio	Total Lines (per Frame)	Active Pixels	Active Lines	Framerate
SMPTE 259M-A	143 Mbit/s	4:3	525	768	486	59.94i
SMPTE 259M-B	177 Mbit/s	4:3	625	948	576	50i
SMPTE 259M-C	270 Mbit/s	4:3 or 16:9	525	720	486	59.94i
SMPTE 259M-C	270 Mbit/s	4:3 or 16:9	625	720	576	50i
SMPTE 259M-D	360 Mbit/s	16:9	525	960	486	59.94i
