http://www.altera.com/literature/wp/wp-3gbps.pdf google can vary order of pages it returns; however I assume you mean this one. 1080p capable using gibi-bits per second of uncompressed video. Society of Motion Picture and Television Engineers (SMPTE) http://en.wikipedia.org/wiki/SMPTE_424M http://en.wikipedia.org/wiki/Serial_Digital_Interface ⟪SDI and HD-SDI are currently only available in professional video equipment; various licensing agreements, restricting the use of unencrypted digital interfaces to professional equipment, prohibit their use in consumer equipment. (There are various mod kits for existing DVD players and other devices, which allow a user to add a serial digital interface to these devices). ⟫ http://www.smpte.org/ It doesn't sound like it should go into first version of the card., it's used in video production environments, possibly as contender to firewire. http://www.altera.com/products/devices/stratix2gx/s2gx-index.jsp ﴾Stratix(r) II GX FPGAs are Altera's third generation of FPGAs with embedded transceivers.

▶The physical interface into the FPGA's transceivers requires an external cable equalizer and cable driver for the Belden 1694A 75-Ω coaxial cable. The cable length can run between 100 to 300 meters depending on the data rate. The cable equalizer is a complex analog component that automatically adapts to the cable length to restore the serial data's eye diagram opening after the dispersive signal loss from the cable's length. On the transmitting side, the cable driver must have enough drive current to handle the load of the long coaxial cable.◀ that pdf referenced says upto 300 meter, but maybe at a slower speed.
