I do not know if they can output more then one of these resolutions concurrently but I suspect that they can since I would assume that the "filmers" would want to save a digital copy of the 1080p/60 content for later use even though they may be are currently scaling it to 1080i/60 or 720p/60 for broacasting.
A year or so back one of the tech supervisors for mobile equipment trucks outlined (HD programming section) how joint 720p/1080i sports events, like ESPN's 720p for weekday golf coverage plus a 1080i network on weekends, are handled: While 1080/60p cameras can output that format, 720p, or 1080i, he mentioned the on-site cameras typically (to avoid mixups) feed 1080i to trucks, then it's either converted to 720p or used as is. The short Ambarella paper I linked earlier discusses 1080p60, with MPEG-4, for broadcasting. And of course 1080 at 60 full frames/sec is much more bandwidth demanding than 1080@24 fps for movies.
Doubt live 3D events like the recent Masters are using or recording 1080p60 camera outputs instead of 1080i30 (1080/60i). 1080p60@3 Gbps, with ~148-MHz sampling--double standard-HD's 1.5 Gbps with ~74-MHz sampling--requires dual-link or equivalent camera outputs. Taping 1080p60 typically involves HDCAM-SR recorders running at double speed (~800 Mbps). It's being used for some movie and archived productions; maybe they'll use and store it for the new 3D channels; recall a news item about ESPN upgrading studios for 1080p60 (storage).
Mentioned RED digital-cinema hardware earlier here since, even though it's not designed for live programming, its output might be modified for broadcasting, boosting effective 1080i resolution and image sharpness after its ~4k downconversion. 3D RED rigs benefit from the camera's compact size, and the digital outputs have a standard bandwidth-saving compressed format; recent sensor/firmware enhancements have boosted dynamic range.
I am not sure what you mean by a 3D computer.
Any PC rigged for 3D-signal output. A different thread topic if detailed, which I summarized
for my current 2D display, supposedly capable of taking a 120-Hz HD input. Yup, we likely still differ on this. -- John
