Good-Bye HDEV, Hello EHDC!
This Ustream channel was originally used to show the views from the “High Definition Earth Viewing” experiment (HDEV). That was an experiment to see how well, and how long, standard consumer-grade video cameras could last in space. The experiment consisted of four different brands of home-use cameras: Panasonic, SONY, Toshiba, and Hitachi models were used. The cameras were aimed at the Earth, and they were powered up and down sequentially. The experiment was designed to last about a year, but in fact ran for over three years before a computer problem ended their transmission in mid-2019. (Three of the four cameras were still functioning quite well!)
Rather than have a channel with nothing to show, NASA now uses that Ustream channel to show Earth views from one of the external High Definition cameras mounted on the ISS. While the HDEV cameras were fixed-focus and fixed-aim, this external camera can be rotated and re-aimed as needed or desired. It also is sensitive enough to low light levels that we can often see city lights on the night side of Earth.
So, what does this camera show? It shows an area off to the left (to port) of the direction of travel of the ISS. Think of sitting in the back seat of a car, and looking out through the left-side front window rather than out the windshield or windscreen. As the ISS approaches distant objects, they appear to move off to the left (port) side in a curving arc. Last, the camera itself is rotated 90 degrees, so that to look more-or-less forward, you have to turn your head sideways to the left.

This is an Operational Stream for Communication and Supervising ISS.
Dark Screen: The ISS cameras are pointing at the night side of Earth.
Blue Screen/SD or Red Screen/HD: LOS = Loss Of Signal, ISS is in a spot without an available video relay satellite.
AOS = Acquisition Of Signal
Images from the Cameras: You’re seeing images from the external ISS cameras, or, during the crew’s working hours, from inside the ISS! There are about 80 cameras, external, internal, on robots, on experiments (for real-time transmissions).
What is Telemetry? Telemetry is the automated communication processes from multiple data sources, collecting information in the form of measurements and relayed using radio,
infrared, ultrasonic, GSM, satellite or cable, depending on the
application, for remote monitoring and analysis of equipments, spacecrafts, Rockets etc.
Here you find ISS Telemetry:
This one displays ISS telemetry, but I would say, more for the ones specialized, w/ knowledge how to use/read/interprete it >>> https://iss-mimic.github.io/Mimic/dashboard.html
This one below is simple, easier, less data >>> http://www.telemetry.space/
The isslive had the best telemetry depiction in the past, not been updated lately (keeping an eye, hoping they fix it). >>>
NASA has taken many Telemetry sites down, in protection and safety of ISS.
