Live video from the International Space Station includes internal views when the crew is on-duty and Earth views at other times.
NASA ISS TV broadcast 24 hour providing live coverage and footage of what I happening and can be seen inside and outside of ISS. There will be some live audio conversation of the crew and Mission Control network in some video.
Because NASA ISS TV provides coverage of the outer space you will also see a sunrise and sunset. Even there are times there are darkness or the camera video appear black you can see amazing views of city lights below.
Even you are not in the outer space, watching the beautiful scenery of space can now be seen by watching NASA ISS TV.
