ISS mystery glitch

Recommended Posts

I know its Secureteam and many do not believe a lot of Tyler's stuff but this vid seems to demo yet again some oddness in the live feeds.

First part is about SpaceX's mystery payload. hmmmmmm Go to 4:37 for the ISS bit. Pretty good glitch IMO, glitching on the Astronots and not the background, LOL!!!!

This is exactly what happens when there is a glitch using video compression tech. Only the first frame is sent in full. Then each additional frame is compared with the previous and only pixels that have changed/moving and their screen positions are sent. The astronauts and the bar on the right are moving, the rest of the image is stationary. Thus when the glitch hits, the smear effect is only on the parts of the image that were changing.

 

 

An explanation of video compression techniques

 

Section 5. The basics of compression

> Reduce color nuances within the image

> Reduce the color resolution with respect to the prevailing light intensity

> Remove small, invisible parts, of the picture

> Compare adjacent images and remove details that are unchnaged between two images

As you put it that way, it makes sense that only moving pixels are sent and replaced. Keeps file sizes smaller I guess?
