I own a Toshiba HD-E1 (HD-A2) player and have just got a new samsung 1080p LCD. The maximum output from this player is 1080i, so the display has to convert it to 1080p. The display uses motion adaptive deinterlacing, where static parts of the picture are full resolution and moving parts are bobbed (see the bottom example in this secrets article). It's not so much the lower resolution of motion video that bothers me, but the chroma bug . - It's very easy to spot on the opening titles of Payback HD-DVD. What I need is a 1080p player, but i'm concerned that if they do internal processing from 1080i to 1080p, that they too will stuffer from the chroma bug. Are either of Toshiba's 1080p players HD chroma bug free?


My PS3 outputs 1080p, chroma bug free with 100% resolution frames, obviously not a lot of use for my HD-DVD movies.

according to those who have tested the XA2 for this, the bug is present but barely, if at all, noticable to the human eye.

What about the HD-EP10 (HD-A20)?

AFAIK, the chroma bug is a DVD encoded error. It is not the fault of the player. The player's responsibility is to be able to filter it out. The XA2 for one does have a chroma bug filter.

No. CUE, chroma upsampling error, is MPEG decoder or "decoder" bug upsampling 4:2:0 to 4:2:2. SD and HD DVDs are encoded in 8bit YCbCr 4:2:0. And I believe some players introduce CUE when going from 1080p24 to 1080i, or 1080p24 to 1080i to 1080p, I can't remember. There's a whole thread about it for one of the players.

As the article says, the chroma bug is introduced when interlaced chroma up-sampling algorithms are used instead of progressive. If the player decoded from 24p -> 60p then it is my understanding the chroma bug could be completely avoided.

Basically if you set your player to output at ANY progressive resolution (480p, 720p, or 1080p) you won't see the Chroma bug at all. It gets covered up by progressive modes.

Not necessarily, the only 1080P HD-DVD players out at the moment use intermediate interlaced processing (they go from 24p on the disc to 1080i, which in turn is converted to 1080p by a secondary video processor, although i'm not sure about the HD-A20), so there is still room for the chroma bug. 480p and 720p is obviously not optimal either!

I don't know what I was thinking when I said this. The XA2 doesn't have a chroma bug filter. That's my Anthem AVM50 I was thinking about.


Sorry. I was wrong in the first statement too. Just ignore the whole thing.

Here's a photograph of the anti piracy logo on new warner discs. Toshiba HD-A2 you can clearly see the chroma bug, Sony PS3 does not have it.

Is that also the case for 720p output? The HD-A2 converts the 1080p on the disc to 1080i and then 720p?
