During working hours the stream shows activities going on within ISS and has ISS to cround communications voiceover. During sleeping hours the video alternately shows earth for 45 minutes and darkness, with maybe some lightning flashes or city lights, for 45 minutes.
It is interesting to see solar eclipses happening every 90 minutes as ISS goes into Earth's penumbra and then quickly into its umbra and then reverses the process 45 minutes later.
