uhm.. Try setting sp, then push : push : push : push : push ... it might be faster.
Anyway, very nice. I just wish it was demonstrated on the original 48k model. ;)
To "expand" pixels, you could probably AND with 170, then write, then XOR the original and write in a line somewhere below; you'd have split every 2nd pixel, so you'd have to mess up the datastreem at the source, but you might get an even better performance.
I'm trying to get my head around this having watched arduino microcontroller video players (of similar black & white quality). From what I gather, lets say they have a microcontroller (amtel) hooked up to a nokia 3310 screen or equivalent, each bitmap pixel is drawn to the screen. No discrete cosine transform compression of anything fancy. My understanding is sketchy. So this spectrum just grabs the image on screen from the video stored on the PC, regardless of the codec. Is that correct?
These eight bit computers from the eighties had loads of potential that were never realized back in the day. All of them did great things if put into the right hands.
It makes you wonder what could have been done with a video digitiser back in the day if there had been one for the spectrum. I remember a big bulky digitiser I had for the Atari ST but obviously that's a much faster machine with better graphics and still you could only capture still or about 2 second video clips.
@graspee I had a digitizer for the ST too. Can't remember it's name, I think it was something like Rombo. I guess you can't catch a lot of video though with 512K of memory.
Nice, but even on the Speccy without multicolor mode you should be able to do better graphically. I assume you're streaming bitmaps here, not character sets - then floyd steinberg would work a *lot* better than patterndithering, since it generates sort of an interlacing effect that shows off details much more than a static pattern that looks the same in every frame... try it!
I've just bought a ZX Spectrum +3, never knew that it was capable of producing video like this. Amazing for such an old machine. Great video thanks for sharing this is absolutely fantastic.
Is that it? You are sending complete bytes to Speccy. Or, you're probably using INIR command, port input in a loop? That would be pretty fast, I guess. ZX didn't have a DMA though.
Memories... Oh, those memories. Bring them back...
@jbase44 It's a memory mapped device, so LDIR to copy out the ethernet buffer to screen (a sequence of LDI instructions would be faster). When the spectranet is paged in there are 4 x 4K pages in the memory map between 0x0000 and 0x3FFF, two of the 4K pages (lowest and highest) are fixed but the middle two can be paged as RAM, flash ROM or ethernet buffers.
@74HC138, oh that's not exactly fair then. ;) Back in 90-s we didn't have the luxury of memory mapping an external device or paging video RAM although some other Z80 and 8080 based computers had it. One could use paging to produce smoother animation.
@jbase44 It makes no difference that it's memory mapped, INI and LDI both take the same number of T-states, and the data still has to be copied from the ethernet chip to the frame buffer. Since I already have to have all the paging for the ROM and extra RAM, might as well memory map the ethernet buffers too since it simplifies the design of the glue logic. (The Speccy 128K does have paged screens, btw, so you had paged video ram in 1986 with the original 128K :-))
As someone who used to own a Spectrum back in the 80's, knowing that people are still out there plugging away making this technology do new things makes me feel kinda warm and fuzzy inside. Well done to you sir, very interesting!
You can achieve higher image quality by pre-processing the stream using a dithering method other than Ordered Dithering as used here, and which is the worst method.
The dithering "noise" should be random, so that at 50Hz frame speed, it averages and becomes less apparent.
this is genuinely amazing!!!. fantastic sir, to whoever figured out how to do this i doth my cap. i'd love to know how to process video with this effect
this is genuinely amazing!!!. fantastic sir, to whoever figured out how to do this i doth my cap. i'd love to know how to process video with this effect
Love the emotional music. Kinda like an old war hero the spectrum here- still fighting the good fight. Completely useless really, but amazing accomplishemnt to do this. Pls do more.
@doodydude234 well, I didn't know the Speccy had a sexual orientation... and considering this was shown live at the University of Zaragoza last week, shown live at RetroEuskal, and countless other shows, and also appeared on Aragón TV, as well as ETB-3 it's provably not fake.
@doodydude234 Yes, we know you are! However, we're *STILL* not interested, so move along now...
@74HC138 Chapeau, mate! That's quite an achievement. Just to be sure, how much processing is being actually done by the Spectrum? And is it required to raise the clock speed? What about sound (or that'll be really pushing it)?
@pastorrtom I suspect the C64 wouldn't have enough memory bandwidth to do it (although the 6502 is fast per megahertz, a 1MHz 6502 is no match for a 3.5MHz Z80 for memory block transfers and the sprite hardware that helped the C64 with games won't be of any help here). However, I could be wrong, I'm hardly a C64 expert.
@74HC138: check knZyPXcelYM ... just note this is transfered via IDE (over a CD-Rom which is also responsible directly outputting the music), rather than over network.
And since we're talking about modern hardware, take a look at this -> Yo7uXaV6Q1s ... sorry but (as much as I like the spectrum) video-streaming certainly is a C64 domain :)
@owczarekn yes, very impressive. But what you fail to mention is that demo needs an external blitter, the C64 can't shift memory around nearly fast enough by itself. This particular demo used the Spectrum's Z80 to make the video. I'm sure with an external blitter it could be made a lot more impressive.
@owczarekn Because the author says so - "It's not a gfx expander -- that's the point. The REU only provides RAM and a blitter that is fast enough to copy the images to normal system memory." In any case, it's pretty easy to calculate, even the most optimized code for a 1MHz 6502 will not do a full screen 4bpp 50Hz video, it simply cannot move the data around that fast. The Commodore REUs effectively behave as a blitter with fast memory transfers that do not involve the CPU (i.e. DMA).
I think that’s just genius what you have managed to do. Back in the 80’s if you had told your school mates that you can stream video on a speccy they would’ve just laughed at you. Pure genius.
Awesome!!! One cuestion, have you uploaded some videos with this kind of image in youtube, or some?? I understad that you are streaming video with a Zx but I am so far of make this device lol, thanks
@prangxxx Amstrad took over Sinclair just after Sinclair released the toast-rack 128K machine (the one with the heasink). All other Spectrums after that were produced and designed by Amstrad. The machine in question (as can be clearly seen) is a Spectrum +3, the last Spectrum model released by Amstrad.

Even mine the 128k +2A (black one - hasn't got the "play" key/command; don't know any other difference from the 128K+2) said Amstrad. Had it new in 1988.
@simond10 what do you mean "looked real until the video started"? If you don't believe it come to the Vintage Computing Festival at Bletchley Park and you can see it for yourself.
This comment has received too many negative votesshow
@74HC138 Are you ever going to watch something streaming with it? I think not. Why not put the hours into something that you, or others will actually use. Don't get me wrong, I appreciate the technical skill gone into achieving this, but it's like someone restoring a steam engine... "now what are you going to with it???"
@keeprighton2007 Why bother watching a film? Why bother learning to play the piano? Why bother climb a mountain? The hours spent making the Spectranet were *fun*. Millions choose to watch to spend more hours watching TV, I choose to spend them engaging my brain and doing interesting things with old hardware. The Spectranet also is a general purpose ethernet card for the Spectrum, it does a lot more than streaming video (basically anything you want to do withi a network)
@74HC138 nice! I think it is fascinating to see what miracles people can accomplish with 8bit computers. Keep it up man. Keeprighton compares ZX Spectrum with a steam engine. Ha, the system is like the basic buildingblock for every modern pc.
@74HC138 Well there are some of us who actually appreciate the hours you put into this I myself am one of them, good work mate look forward to seeing any future projects you have going on.
@74HC138 Yes, hacking hardware gives me a sense of accomplishment. Then again, my idea of hacking hardware is taking an AUX cable and using it with the HEAD socket on my laptop, and the MIC socket on my stereo. Still, a sense of accomplishment!
ha why are you watching RTL II? that's a German station.

I needed this in 1981 for my ZX81 to watch porn!
(I wonder what Debbie Does Dallas looks like on a Sinclair!?)

Awesome but one question....Why does it say Amstrad? Spectrums are made by Sinclair....(cough cough)
prangxxx 1 year ago
@prangxxx Amstrad took over Sinclair just after Sinclair released the toast-rack 128K machine (the one with the heasink). All other Spectrums after that were produced and designed by Amstrad. The machine in question (as can be clearly seen) is a Spectrum +3, the last Spectrum model released by Amstrad.

@74HC138
Even mine the 128k +2A (black one - hasn't got the "play" key/command; don't know any other difference from the 128K+2) said Amstrad. Had it new in 1988.

Amazing stuff man. I didn't knew that people still bothered developing things in basic spectrum.

@simond10 what do you mean "looked real until the video started"? If you don't believe it come to the Vintage Computing Festival at Bletchley Park and you can see it for yourself.

On the current technlogical level it means one can have video on a wrist watch)

That was fantastic! I can't believe how many people just don't get it. This is just too cool.

I think it is petty cool. I would have loved to see video like that, even tiny clips back in the early 80's.

This comment has received too many negative votes show
@74HC138 Are you ever going to watch something streaming with it? I think not. Why not put the hours into something that you, or others will actually use. Don't get me wrong, I appreciate the technical skill gone into achieving this, but it's like someone restoring a steam engine... "now what are you going to with it???"
keeprighton2007 1 year ago
@keeprighton2007 Why bother watching a film? Why bother learning to play the piano? Why bother climb a mountain? The hours spent making the Spectranet were *fun*. Millions choose to watch to spend more hours watching TV, I choose to spend them engaging my brain and doing interesting things with old hardware. The Spectranet also is a general purpose ethernet card for the Spectrum, it does a lot more than streaming video (basically anything you want to do withi a network)

@74HC138 nice! I think it is fascinating to see what miracles people can accomplish with 8bit computers. Keep it up man. Keeprighton compares ZX Spectrum with a steam engine. Ha, the system is like the basic buildingblock for every modern pc.

@74HC138 Well there are some of us who actually appreciate the hours you put into this I myself am one of them, good work mate look forward to seeing any future projects you have going on.

@74HC138 Yes, hacking hardware gives me a sense of accomplishment. Then again, my idea of hacking hardware is taking an AUX cable and using it with the HEAD socket on my laptop, and the MIC socket on my stereo. Still, a sense of accomplishment!

@74HC138 I was berated for collecting old computers, it was deemed pointless by my critic. I think its just a form of jealousy when
