This is a distinction without meaning: all digital anything is analogue if you look closely enough

> And that was because computing power back then was non-existent so they didn't use any kind of compression?

Compression is not a medium-level detail. You can easily store compressed data on a laserdisc.

No, with digital, you need encoding. How can you even compare binary with embedded images.

How are the images encoded?

[brazzy]

In ways that ensure that they are not visually recognizable on the physical medium afterwards, because the visual layout represents a whole lot of redundancy, and the job of compression is to remove redundancy. If the end result has any recognizable patterns, the compression is not doing its job well.

[system2]

If you watch the video, you can see that the images are burnt to the medium and can be seen optically. With 1 and 0, you cannot do this. All you'd see would be random dots everywhere.

Your CED or laserdisc player needs to be smart enough to be able to decode whatever you put on it, which- in the era that they were relevant- pretty severely limited what you could do.
