    DVDO Iscan HD

    The iScan HD will 'up-convert' a video signal as long as it is one of the following: 1) Composite video - NTSC, PAL or SECAM 2) S-Video - NTSC, PAL or SECAM 3) Component (YPbPr) - 480i, 480p, 576i or 576p 4) RGBs (i.e,. RGB with composite sync) - 480i, 480p, 576i or 576p 5) DVI (not HDCP...

    Chroma bug only in progressive scan?

    The 504 does not remove CUE artifacts. The Faroudja deinterlacers do, but only incidentally as they only use a single field of chroma even for film sources. While this has the (unintended) benefit of largely removing CUE artifacts, it also introduces other problems, such as flicker with sharp...

    Panasonic DVD-F85/87? Video quality? Chroma Bug? ..using interlaced output.

    The chroma bug (CUE) is caused by a design defect in the MPEG decoder. The deinterlacer has absolutely nothing to do with it, outside of makng the original problem more visible since interlaced video tends to hide CUE artfacts somewhat. Both CUE (when present) and ICP (which is always there)...

    Chroma bug only in progressive scan?

    There's at least a bit of misinformation being posted here. CUE and ICP, while related in terms of the net visual effect and the fundamental cause (interlacing), are different beasts. CUE is introduced in the MPEG decoder when video material encoded as (effectively) progressive is decoded as...

    Iscan Plus V2 Problem w/ CAV Laserdiscs

    John, If the iScan is behaving well otherwise, particularly with CLV discs, then perhaps the problem is with your laserdisc player and not the iScan. The iScan has no way of 'knowing' whether a particular disc is CLV or CAV, but your player certainly does. It's probably the only element in...

    Does SilL504 do upscale?

    I have to admit that the logic escapes me here. Chip A has more features than Chip B, so Chip A must cost less. Okay. . . . Also, when did Faroudja (Genesis) announce a FLI23xx chip which has a built-in DVI w/HDCP transmitter? - Dale Adams

    Does SilL504 do upscale?

    So what exactly are the prices of the SiI504 and the FLI23xx chips? - Dale Adams

    Line Doublers and Projectors

    When the DVDO website says that a display "should" be compatible, it means that the published specs for the projector indicate that it should work, but that there's no hard data or direct empirical evidence available that says that it actually does work without any problems. If you have a PC...

    Line Doublers and Projectors

    Your projector has a VGA input which is intended to accept RGBHV computer signals. If a line doubler can produce an RGBHV output (like the iScan Pro can), then it will almost certainly produce a picture on your projector. Whether it will be better than what you have now or not depends on a...

    Denon 2900 video based chroma bug?

    What you're seeing is an inherent limitation of using 4:2:0 encoding for interlaced video. I think the Secrets guys dubbed this one "ICP", or interlaced chroma problem. It's produces very much the same onscreen artifacts as the 'chroma bug', but it's not really a defect of the MPEG decoder...

    Dvdo Iscan Plus On The Blink !!!!

    Troy, If there are no lights on at all, it's most likely the power supply. You can get a replacement by contacting DVDO customer support at 1-866-423-DVDO, or you can check their website at www.dvdo.com. - Dale Adams

    Video flicker / instability / dropout during white scenes

    Andrew, I wouldn't assume it was a design defect in the player. It could just as easily be considered a design problem with your display being unable to track variations in the input. Some players might trigger that sensitivity and while others wouldn't. (I suspect you didn't try replacing...

    Video flicker / instability / dropout during white scenes

    Mike, I haven't heard of this type of problem just spontaneously occurring before. I suppose it's possible if the system was right on the edge of the problem happening and then something changed - electronic component drift over time, power or system grounding variations, or some other...

    Video flicker / instability / dropout during white scenes

    Mike, This type of problem usually occurs when the output of a video source device is AC-coupled and the average DC level of the signal then varies with the picture content. Large variations in the image, such as bright flashes or when 'the screen goes all to white', cause the DC level to...
