Testing and Deploying the Solution
For testing purposes, AEGraphics was supplied with two Matrox DSX LE3/4KO/550 SDI video cards, which were installed in an HPZ820 chassis supplied by Vizrt.
On receipt of the equipment from Vizrt and Matrox, AEGraphics began a stringent testing and development phase in their UK head office. They found that the workflow for 4K did not differ significantly from their previous workflow. In fact, AEGraphics was happy with the way that the 4K process fitted into their standard graphics workflow—providing fill and key signals to a switcher that overlaid the graphics onto live video content. Each Matrox DSX LE3/4KO/550 card fed four 3G SDI signals to carry one 4K feed. One card provided the fill signal and the second card provided the key signal to the switcher. The system performed well for 4K in testing and was shipped to various outside broadcast sites at the Cricket World Cup in Australia and New Zealand.
AEGraphics provided the output of its UHD Vizrt machine direct to NEP Australia (the facilities provider), who provided both the 4K production and broadcast facilities. There was some concern about the synchronization of the eight SDI channels that the fill and key signals consisted of and both AEGraphics and NEP were impressed to find that the signals were delivered in sync by the Matrox cards at all times.
Eight flypacks that included four Viz Engines driven by AEGraphics software were supplied for the host broadcast main graphics feed. An unbranded slave feed was also provided for Doordarshan, the Indian terrestrial state broadcaster. In addition, the ICC (International Cricket Council) needed an independent feed for the large arena screens, which required bigger fonts for better legibility. The graphics were driven by in-house software applications. This allowed for quick population of graphics with data and also removed the chances of errors.
For their regular HD graphics delivery on Cricket World Cup coverage, AEGraphics used 24 HP Vizrt machines with Matrox X.mio2 Plus SDI video cards. AEGraphics uses Matrox cards extensively. Three Matrox X.mio2 Plus cards are used in every one of their eight OB (outside broadcasting) vans in the UK for regular HD workflows.
