Here's some background on the production from the ESPN press release.
A one-hour preview show airs from Indianapolis Motor Speedway at 11 a.m. ET, with the race telecast, presented by Go Daddy, at noon. The green flag for one of the world’s iconic and most historic sporting events is at 12:15 p.m.
ESPN’s production of the Indianapolis 500 on ABC will utilize 84 cameras to televise the premier event of the IZOD IndyCar Series, including three onboard cameras per car in 12 of the 33 cars competing in the race.
Among the cameras will be the newly-enhanced “Batcam,” a camera that provides unique and dramatic views running on a cable over pit road and the frontstretch and has been utilized by ESPN at Indy for several years. But with new technology, “Batcam” can now move faster than ever, reaching speeds of 95 mph.
Views and replays also will be enhanced with expanded usage of four Ultra Hi Motion cameras. As was the case last year when the cameras were used for the first time, they will be located in the short chutes at each end of the 2.5-mile track as well as at the fourth turn exit, with a fourth robotic camera added this year to provide a low shot entering the first turn. The cameras can shoot at speeds of up to 1,200 frames per second. ESPN also will have Super Slo Motion cameras positioned in each turn.
Viewers of the ABC telecast will have the option of a second screen experience through a choice of live streaming video from the onboard cameras on ESPN3, ESPN’s multi-screen live sports network. ESPN3 will carry the feeds exclusively through WatchESPN and on Indycar.com to fans who receive their Internet or video subscription from an affiliated provider. Viewers will be able to choose which driver’s onboard cameras they want to watch from among the available cars and this year, for the first time, all of the feeds also will include ESPN’s live scoring ticker. ESPN3 also will have replays of the ABC telecast following the event. ESPN3 is available online at WatchESPN.com, on smartphones and tablets via the WatchESPN app and through ESPN on Xbox LIVE.
Marty Reid will call the race with analysis by former IndyCar driver Scott Goodyear and 1998 Indy 500 winner Eddie Cheever. ESPN SportsCenter anchor Lindsay Czarniak will host the telecast while pit reporters will be Rick DeBruhl, Jamie Little, Dr. Jerry Punch and Vince Welch.
NBC did the F1 race today with 16:9 graphics feed and letterboxed the SD feed. ABC is full screen 4:3 on the SD feed. Audio is DD 5.1.
