• 5.1 format / LPCM / 24 bits / 48 kHz
• 7.1 format / LPCM / 20 bits / 48 kHz
Notes:
• DisplayMode = Single : is applicable to both DisplayPort A, and DisplayPort B input, separately.
• DisplayMode = A+B : inputs DisplayPort A and DisplayPort B are combined to 1 larger image; in this case
the 2 DisplayPort links need to be genlocked ( = synchronous and in phase).
• In all cases :
- Color Space - Color Sampling:
◦
YCbCr - 4:4:4
◦
YCbCr - 4:2:2
◦
RGB - 4:4:4
- Scan Type = progressive.
• Both Nvidia and AMD GPU's will not support color depths of 10 bits/color while in 3D-stereo mode.
• Some Graphical Cards may not permit 10 bits/color at all video timings, because of bandwidth restrictions.
• DisplayPort A and DisplayPort B automatically detect:
- Active Pixels, and Active Lines
- Vertical Refresh
- 8 bits/color - 10 bits/color
- Frame locked
• All input resolutions are scaled towards the desired resolution specified in the screen presentation file.
• Fractional frame rates = (Hz*1000)/1001
8.15 ICMP(-X) SDI specifications
3G-SDI
Serial Digital Interface (SDI) is a serial link standardized by ITU-R BT.656 and the Society of Motion
Picture and Television Engineers (SMPTE). SDI transmits uncompressed digital video over 75-ohm
coaxial cable within studios, and is seen on most professional video infrastructure equipment. The
first revision of the standard, SMPTE 259M, was defined to carry digital representation of analog
video such as NTSC and PAL over a serial interface and is more popularly known as standard-
definition (SD) SDI. The data rate required to transmit SD SDI is 270 Mbps. With the advent of high-
definition (HD) video standards such as 1080i and 720p, the interface was scaled to handle higher
data rates of 1.485 Gbps. The 1.485-Gbps serial interface is commonly called the HD SDI interface
and is defined by SMPTE 292M, using the same 75-ohm coaxial cable. Studios and other video
production facilities have invested heavily on the hardware infrastructure for coaxial cable and have
a vested interest in extending the life of their infrastructure. Fortunately, SMPTE recently ratified a
new standard called SMPTE 424M that doubles the SDI data rates to 2.97 Gbps using the same 75-
ohm coaxial cable. This new standard, also called 3-Gbps (3G)-SDI, enables higher resolution of
picture quality required for 1080p and digital cinema.
SDI terminology
Standard HD-SDI signal (Single Link)
1.5Gb/s HD 4:2:2
Standard HD-SDI allows for a single 4:2:2 image to be carried on one cable at 1.485 Gb/s. The image uses
the Y Cb Cr colorspace and uses a bit depth of 10 bit per color component.
Due to the data rate limitations only 23.976, 24, 25, 29.970 and 30 fps streams are achievable.
