System Design Showcase: The International Dota 2 Championships

TNDV and Graystone Media joined forces for the three-day gaming event that was broadcast to three continents in three languages.

TNDV technicians monitor multiple in-house, live streaming and recording feeds on-board the Aspiration truck using Harris HView SX Hybrid multiviewers.

Quality viewing

TNDV’s infrastructure typically produces 1080i HD broadcasts for televised events. The team quickly discovered that 1080i nearly equates with standard definition in the gaming world. It was clear that every pixel and graphic on that screen would be critiqued — all the more intimidating as that judgment would come from gaming experts who create pixels for a living.

Modern gaming offers very high resolutions, with an amazing amount of on-screen detail. We added several Barco ImagePRO-3G signal processors to scale and transcode video for 1080p-quality output. This translated the game’s finer visual details well, with in-house attendees and viewers able to clearly see the flares, sparkles and flashes that take place when an on-screen character casts a spell.

Those seated in the venue were, therefore, treated to exceptional projections, with three distinct screens. Team A and Team B were seen at left and right, with a center screen switch of the various cameras and real-time computer-screen shots.

The Graystone Media team worked closely with TNDV on delivery of graphics, using Chyron HyperX systems on Aspiration to build a database of graphics packages for playout. Trifilm worked closely with Valve on graphics creation, providing head shots, team shots, player statistics and full-screen graphics with team information among other impressive visuals.

Graphics accompanying the live video were carefully balanced for required variances for live AV projection (big and robust) and web streaming (small yet legible). Graphics, however, were just one component where careful considerations were made to ensure a unique experience for both the venue and the broadcast.
