However, it is possible to extract high-resolution images from multiple frames of low-resolution video.

Yep. Happens because the phase of the sampling grid changes on different frames, which effectively increases resolution.

that's also why 1080i effective resolution is more than simply 540 lines of resolution (1080i for a sitcom has a higher effective resolution than 1080i watching a a sporting even, which is also why I think ESPN chose to transmit it 720p, at least for some time, as opposed to 1080i, but could be wrong about that)
