I'd love to see some figures to back that claim up. IMO, neither the Archimedes hardware, nor the typically available bandwidth in 1995, could even come close to coping with HD.
Well I had a 400x300 256 colour video of the original Thunderbirds 2 countdown running from a 1.8M (3.5 inch floppy) on my original 440 Archi, by the time 1995 came along we had the Risc PC (which according to DEC and Byte magazine was the fastest micro in the world at the time).
The trouble with MPegs etc is that you compress it at source send it down the line then decompress (both video and audio, there is no sync) at the other end, with the Replay system it was just a stream of data, compressed at time of capture. The RiscPC hardware had some clever adaptations which basically allowed for any theoretically possible screen dimensions and refresh rate coupled with a maximum colour depth only restricted by the bus size. In 1995 I was running 1280x1024 in 24bit (note that my first RPC was a mk1 with an arm610 cpu which used the top 8 bits for some cunning memory address techniques) 16M colours (analog in those days), and doing typesetting for various people. I also had the Video editing suit that allowed capture and 'compression' of video sources (you needed very large hdd's for this, mine was 200mb
) into Replay format. I captured all of the Gerald scarf animation sequences from Pink Floyd's The Wall and spliced them to together (this was at 800x600x1024 colours, probably better than the VHS it came from).
There were some pretty large 'pipes' around even in 1995, but these were mostly for commercial usage.
Acorn and ICL (along with Sainsburys, Tescos, high street banks, BBC and ITV) run a 15,000 home experiment around that time which allowed for on-line shopping, off-line viewing of downloaded video and games. Can't find the wiki for it now, but in it's day it was the 'way forward', and so it has proved, albeit using the internet and not dedicated lines.
