    Is DVI really much better than component?

    DVI actually has to be post-deinterlacing, because DVI is progressive-only. HDMI adds a 480i mode, but it's not widely used yet. Don

    Competing HD formats

    Mike, I'm not really sure that argument would have much effect on the studios. There aren't that many people with $3000 speaker systems. I agree that there is an audible difference between DD at current bitrates and the master recording (which MLP is just a lossless compressed version of)...

    Competing HD formats

    Audio, bah. :) Without the audio, video is still good. I can make up my own dialog, hum a tune, make sound effects with household objects. But if you leave the audio on and cut off the picture, I'm blind! Aaaaaa! What's that noise? Is that crunching leaves or someone's head being crushed by a...

    Competing HD formats

    Well, I took a quick poll of those who know more than I, and I take it all back. There is a reasonable chance that MLP will become a standard format on HD-DVD. Dolby Digital will almost certainly be one as well, as will DTS and straight PCM. All the standard formats will be supported by every...

    Competing HD formats

    John, Respectfully, I think you are foolish. :wink: But seriously, you're of course correct that it would fit, but I just can't see the studios devoting that much bandwidth to uncompressed audio. Heck, I very much doubt anyone could tell the difference between MLP and, say, 1 Mbps Dolby...

    Competing HD formats

    Well, I personally have no problem with Dolby Digital. It's well regarded in the industry, and it's the most commonly used digital format in movie theaters. I certainly don't think MLP is a good choice for a general HD format at this stage. Lossless audio compression is, IMO, complete overkill...

    Competing HD formats

    Actually, lower density with a newer codec can look better than MPEG-2 at a higher density. I've seen the proof - the same content compressed with MPEG-2 professionally with high-end encoders at 28 Mbps compared with WM9 compressed with a desktop PC at 9 Mbps, and the WM9 looked significantly...

    Competing HD formats

    MPEG-2 is an inferior codec to WM9 or H.264 or most of the other next-gen video codecs in every possible way. At the same bitrate, any of the newer codecs look much closer to the original source than MPEG-2. Heck, they look closer to the original source at half the bitrate. The only reason to...

    HDTV Aspect Ratio

    Also, as Matt mentions, the Sony WSS solution only works in 480i. They didn't implement it for 480p, even though it would have been relatively trivial - it's one line 21 of the vertical blanking area, and line 21 exists in progressive as well as interlaced. Of course, I'm not actually sure...

    HDTV Aspect Ratio

    Sony implemented WSS (Wide Screen Signalling) on some of their 4x3 NTSC TVs and some of their DVD players. Kudos to Sony for taking a stab at this problem, but I believe it's only a PAL standard, and Sony just appropriated it for their NTSC sets. It's possible that it's a legal (but obscure)...

    HDTV Aspect Ratio

    I'll leave aside Phil's comment about "natural wide" as he knows my feelings about that. :) Folks, this is very simple. In NTSC and PAL, you can have 4x3 video or 16x9 video. Those are (so far) the only two aspect ratios available. Sadly, there is no way to distinguish the two electronically...

    HDTV Aspect Ratio

    George, believe me, I know much more about this than thedigitalbits.com (not that I have anything against The Digital Bits; they do a great job). I'm a developer at Microsoft on the digital video team. I know the DVD spec inside and out - I have a copy on my desk. I am not guessing when I say...

    HDTV Aspect Ratio

    "Full" is not a stretch mode. "Full" is a normal 16x9 mode. HDTV is 16x9, as is so-called "anamorphic" DVD. They're both 16x9, so the TV needs to be in 16x9 mode. Q.E.D. The other modes, like "natural wide" (which gets my vote for 'least accurate description') are different ways of converting...

    Which of the following plagued with "Chroma Bug"?

    All the current models of Panasonic DVD recorder use the new MPEG decoder that has the bug, to the best of my knowledge. I've only personally seen two of the recent models, but it would be very strange for them all not to share a common design. Their first model or two from the previous model...

    Which of the following plagued with "Chroma Bug"?

    Stephen, I don't know of any Panasonic RP32. RP was their prefix for progressive models, and the 32 wasn't progressive. The RV32 has no chroma bug. No Panasonic models have had chroma bug up until this year's models, which changed to a new line of MPEG decoders that have chroma bug. There...
