XOS HD Replay System Leverages AJA Video Technology

This college football season, many officials are getting their instant replays in uncompressed HD for the first time thanks to the XOS HD Replay, which is based on video technology from AJA Video Systems.

Earlier this year XOS Digital introduced XOS HD Replay featuring AJA’s KONA LHi capture and playback cards and HDP2 Mini-Converters. The SEC was the first to adopt the HD Replay system with other conferences joining over the course of the season. These conferences include the Big12, the WAC (Western Athletic Conference), and Conference USA.

The XOS HD Replay system takes an uncompressed HD-SDI video feed from the on-field broadcast truck and captures it via an AJA KONA LHi. The HD-SDI output of a second KONA LHi card is routed through AJA HDP2 Mini-Converters to play back the uncompressed HD video on standard computer monitors in a replay booth, for the game’s dedicated replay official. With multiple play angles in superior image quality, replay officials are able to get the conclusive video evidence they need to uphold, overturn, or confirm an on field call or coaches’ challenge while enabling decisions to be made by the replay official in a minimum amount of time.

“The capabilities of the KONA card are the life-blood of this system,” says XOS Digital Director of Development Tom Fuller. “It offers the highest image quality and is imminently reliable. That’s critical because the goal of the system is to enable officials to do their job faster and more accurately. The HDP2 converters are also key because they use a very high quality scaling engine and de-interlacer that enables us to play out to cost-effective HD resolution computer monitors so we’re able to keep costs competitive without sacrificing video quality.”
