Product Features
This chapter contains information on special features associated with the AMD
FirePro V7900 SDI.
Serial Digital Interface (SDI)
Serial Digital Interface (SDI) consists of a series of video standards used in the
professional video industry to provide broadcast-grade video. SDI is standardized by
the Society of Motion Picture and Television Engineers (SMPTE) and is used to transmit
uncompressed digital signals with or without embedded audio within television
broadcast studios.
SD-SDI, the standard used for standard-definition video, provides data rates up to 360
Mbits/s. HD-SDI, the standard used for high-definition video, provides a nominal data
rate of 1.5 Gbits/s. For greater high-definition needs, the Dual-Link HD-SDI and 3G-SDI
standards also exist to provide even faster data rates.
Due to their high data rates, SDI interfaces are intended only for short distance
transmission and professional use.
Note: To use SDI functionality of your AMD FirePro V7900 SDI graphics card, a
certified SDI I/O card is required. For a list of certified SDI I/O cards, see
www.amd.com/sdi-tech .
Note: SDI is not enabled by default. To enable it, see Enabling SDI .
MultiCard Support
MultiCard Support is a feature that enables you to fully use the power of your AMD
FirePro graphics cards when more than one card is installed in a single system with
multiple displays.
With MultiCard functionality, each OpenGL graphics application automatically uses
the graphics engine of whichever GPU is associated with the display on which the
application is initially launched. Users who wish to run two OpenGL graphics
applications can take full advantage of their two GPUs by ensuring that the two
applications are launched on displays connected to different graphics cards.
For example, in a configuration comprised of four displays attached to two graphics
cards, you can obtain optimal performance for two OpenGL applications by launching
the first application on a display attached to graphics card #1 and launching the second
application on a display attached to graphics card #2.
