He wants to see the event, not the phones (recording the same video). His interests conflict with other visitors' interests - to have a recording, so they could re-watch and refresh the memories later, or share video with friends. Obvious solution (for event organisers) would be to hire a professional cameraman recording the event and broadcasting the video stream over WiFi to everyone who attends the event, so they could have a copy (they would, anyway). Visit the event, see the QR code on the wall (or ticket), download an app, put a phone in your pocket and get a nice recording - it's this simple. If the pricing's right, and restrictions (okay, organisers want to squeeze some money so there probably would be some sort of DRM) are fairly lax - attenders won't take their phones in air, event organisers will get additional income, problem solved. If the pricing's wrong or DRM is over-restrictive, attenders would take the recording with their phones. (If someone's worried that the streamed video will complete with DVDs/Blu-Rays - it could be of lower quality, but the quality must be competitive with self-made typical-cameraphone recordings.)
