Also shows some interesting data from some new instructions, like the spiral is using the cordic instructions.

I attached a zip of a higher resolution version of the image so you can see it better.

    So, will it be able to do DVI/HDMI?
    I'm assuming that this is VGA!?

    This is using component connections (YCrCb) which most HDTVs have.

    Component video is not very common in Europe at all!

    It'll still do vga, but not HDMI (according to Chip).

    My TV (not HDTV) has HDMI, but no component video. It does have component audio, whatever that is.

    Leon, I think if it has HDMI, then it's an HDTV almost by definition... What's your make and model? I'm curious what that could be...

    It's relatively easy to convert to HDMI using an external chip, but that would require 24 pins to get 24 bit color. Maybe it'd be better to also use an external ADC to save pins... But, you can just buy a VGA to HDMI adapter of Amazon.com for $38...

    I haven't seen an HDTV that didn't have a VGA connector, but haven't looked real hard...

    Panasonic Viera TX-L19X10BW.

    I think you are right, it's described as "HD ready". It has VGA input.

    Leon,
    Older "HD Ready" sets often had DVI inputs not HDMI. There are adaptors on the market that will convert the connection from VGA to DVI.

    That TV has an HDMI input, I've tested it with the HDMI output from the graphics card in my PC. I'd like to try it with my Dell Streak, but I need to buy the docking station.

    BTW: You really have to check your TV manual to see what you have sometimes...

    One of my TVs has a component input using the VGA connector!
    Apparently, there's some quasi-standard where some of the unuses VGA pins are used for component video...

    Ok, that's definitely an HDTV. BTW: "HD ready" just means that it doesn't include an over-the-air HDTV tuner. A lot of TVs from a few years ago were like that. They're rare now as the government requires new TVs (except maybe tiny ones) to have tuners...

    Looks great Roy, thanks for the picture.

    Not only are component signals sometimes stuffed into a VGA connector, there are TV signals too. Matrox did it, and may still do it, offering a chroma and luma signal on the VGA. Used to have a cable for a older G400 series card that I could use for S-video display.

    Deffo read the manual. Anything might be possible.

    @Leon: I've a Viera series set here, and it's got component, no VGA, multiple HDMI inputs.

    Thanks Roy - I am drooling at that pic.

    Regarding HD Ready - I think some of the older sets that have HDMI may not have a working HDCP implementation (I think no set should have HDCP, but that's another discussion entirely)

    Roy, did you generate the picture using a Prop 2 simulator? If so, can we play with it also? Pretty please. :)

    Yeah, "HD Ready" typically means no HD tuner (i.e. like a PC monitor) but some way of providing an "HD" signal to the display. Of course, since "HD Ready" wasn't a specific standard, neither was the input. "HD Ready" displays often had lower specs than modern HDTVs - i.e. only supporting 720p/1080i and having 1024x768 panels.

    Most (all?) VGA<->DVI adapters rely on the analog pins of the DVI connector. Of course, that means that if the DVI side doesn't support DVI-A then the adapter doesn't work. VGA<->HDMI adapters are digital, but are more expensive.

    Dave,
    That was using the big FPGA board Chiop has for developing the Prop 2. It's like $2500 plus some custom boards parallax made to attach to it. So you can't really have it :)

    Others:
    I talked with Chip a bit about HDMI and DVI, and the main problem is that they are digital and to get 1080p would require higher pin signalling rates than will be possible on the Prop2. It may be possible to do lower resolutions over a DVI or HDMI cable (minus the encryption stuff). It's something that one of you folks will have to try.

    My initial calculations, based on my current understanding of the state of the Prop2 design (enough disclaimers?) suggests that 720p / 1080i HDMI out *may* be possible, but I cannot estimate the probability of success without studying everything about the new counter / SERDES modes, HDMI protocol, and exact timings.

    Roy, now I want to play with it even more! I should have realized it was a live video signal displayed on a monitor. Now that is really cool.

    WAIT !!! *** !!! --- I recognize the left column binary sequence in the OP video image.

    Please comment on what uses there are for the sequences of binary numbers with a constant number of 1's,
    and any info on how to quickly convert between normal numbers and binary numbers constrained to a constant number of 1's.

    If %1111111111111111 == 1 (and %10111111111111111 == 2) then what is %10101010101010101010101010101010 == X?
    And the inverse, what is %X == 1048576?
    I need a function and its inverse that's quick for large numbers.

    Just one word of caution that many HDTVs don't support 1080p via the VGA input. Monoprice has a component + S/PDIF to HDMI converter for US$35.
