If you're in the industry, you'd know...
Most persons 'in the industry' can barely tie their own shoe laces nevermind understand a file format to any depth above wading pool level haha
that digital signals processed at 1 bit (not our whopping 64 bit of today), at millions of samples per second: are twice as resolute as 2 inch
reel 24 track tape, or full chroma film. 1 bit facilitates far less processing power & allows for full redundancy (you can record multiple frames at
once, in case a frame is dropped).
The method you're talking about is most likely DSD?
1 bit doesn't mean less processing power ... it means more in this context since by its very nature it's a codec. These days it doesn't really
matter, since a good editing rig tears up audio files. In the 60s though? A digital low pass filter would destroy a calculator nevermind more complex
A WAV file, for example, is already decoded. It use more data thru-put because it's large in data size, but less processing power because it's
decoded. DSD formats use less space but more processing power to decompile.
It's still lossless because the data can be retrieved, but I wouldn't describe it in the way being presented. I also have no idea what your
reference to 'full chroma film' means in this context, but DSD does not translate to being better than say R3D encoding etc etc ... blah blah ...
I know this, because I record audio at 1 bit/2.6 million samples per second. This technology was available to the public via the Sony
corporation, since the late 1970s.
DSD as we know it wasn't really developed until the mid to late 80s by Sony. People had the idea earlier, but people also had the idea of using
fourier transforms with images before Adobe Photoshop and modern computing gave us the power to do it.
Vague history here
. There is a lot more
information around as to why Sony developed the file format. If it was anything to do with the military they would have been somewhat more confident
in their internal use of it.

I'm from the school of thought, that the military has had advanced flash based RAM recorders since the 1950s.
They would have had to be bigger than anything available decades later. Circuitry would also have to be able to encode/decode DSD file formats which
would make the army 20 - 30 years ahead at least.
One of the larger elephants in the room though is they would need a file
to store the large file sizes. Bill Gates and Marc MacDonald didn't do that until 1979 forward ...
Think of gun camera footage, from old wars. Film would have taken too much space, for too little footage. Video transmission would be too
un-secure, and resolution would be low. How can we watch half hour dogfights?
Random funny point, as recent as this decade they've attached unencrypted cameras to drones. Admittedly, people got fired, but it happened.
And no disrespect, but unless I'm totally missing something or there is some new 1 bit file format that no one told me about, this doesn't make
By all means, I won't be upset if you correct me or simply say 'oh no, I really do think they had that technology.'
