Eyeheight Video Keyer Delivers the Action at Wimbledon 2014

Eyeheight DK-2 multi-rate linear downstream keyer

An Eyeheight DK-2 multi-rate linear downstream keyer delivered the excitement of the 2014 Wimbledon Lawn Tennis Championships to television viewers around the world. The keyer was chosen by one of Britain's largest outside-broadcast service providers. It was deployed to add contestant identifier overlays which were faded in and out over the live action using a Eyeheight VP-10 video T-bar module. The event was held at its traditional venue, the All England Lawn Tennis and Croquet Club in south west London, from June 23 to July 6. Andy Murray of Great Britain was the defending champion in men's singles but lost to Bulgarian tennis star Grigor Dimitrov in the quarter-finals.

"The DK-2 performed successfully at the 2013 Wimbledon tournament and has was chosen again for broadcast coverage of this year's event," says Eyeheight Sales Director Martin Moore. "Nearly 10 million viewers saw Novak Djokovic's win in the men's final. Up to six DK-2 keyer channels can be accommodated in a single FB-9E chassis occupying just 1U of rack space which makes it a powerful option wherever space is at a premium."

Compatible with all commonly used 625/525-line standard-definition, 720p intermediate-definition and 1080i high definition formats, the Eyeheight DK-2 incorporates background, fill and key inputs, wipe, matte and garbage-matte generation, independent main and preview keyers plus EDH reinsertion for the main output. It is fully transparent to SDI-embedded audio and other ancillary data. Mechanical relay bypass is available as an option. Features include 10-bit linear keying, manual or automatic transitions, a user-selectable choice of additive, multiplicative and self-key modes, and AES digital audio voiceover.


The DK-2 is equipped with inputs for slave fill sync, slave key sync and master input line sync plus independent programme and preview outputs. An RJ45 port allows connection of three GPI channels and tally as well as RS232-based on-board protocol control. It can be fully operated via Ethernet from anywhere in the world.

Held at the All England Club in southwest London since 1877, Wimbledon is the world’s oldest tennis tournament and the only event of its kind still played on grass. The tournament takes place over two weeks in late June and early July, leading up to singles finals. Five major events are contested each year, as well as four junior events and four invitational events.
