What does "tbr", "tbn", and "tbc" mean?

Mark Filipak
In this ffmpeg output listing:

Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, top first),
720x480 [SAR 32:27 DAR 16:9], Closed Captions, 29.97 fps, 29.97 tbr, 90k
tbn, 59.94 tbc

what does "tbr", "tbn", and "tbc" mean?

I've searched the documentation but have not found Joy.

Thanks!

   - *tbn* = the time base in AVStream that has come from the container.
   - *tbc* = the time base in AVCodecContext for the codec used for a
   particular stream.
   - *tbr* = *tbr* is guessed from the video stream and is the value users
   want to see when they look for the video frame rate.
