Are interlaced fields encoded separately?

This is a question regarding interlaced video that I've never received a firm answer on.

Question is: are the fields in interlaced video actually encoded separately? This would mean that the fields exist separately in the video stream and are recombined by your video player. Or, are the fields encoded into the same frame as a progressive video, and the term "60i" is simply used to describe how the video is visually perceived?

If the former, how can I check that a video is truly interlaced, and not just a progressive video with interlaced frames?
