Deep Color and X.V. Color - Questions

[Pelican170]

Ok, i have a question about "deep color and x.v. color". Now, if a tv accepts such things, does that mean the source has to output it? Does the PS3 output such Color options? Will a receiver accept this automatically or do only certain receivers accept this? Obviously i dont quite understand it so any info will help?

this is a spec of HDMI 1.3, but just because something is labeled 1.3 does not mean it is automatic. The device has to specifically support it.

...and yes, if the source is not in deep color, then its not deep color. etc

The only real deep color/x.v color source is is used in video cameras... and perhaps a few other non mainstream products. But as for the average joe shmoe...nada.

and yes, the PS3 can output.

From what I read a year ago, these were tech features available on newer HD camcorders, for playback, weren't they?

ok i see. so is this used for blurays? im asking because my receiver is HDMI v1.1. If i got a new tv that accepted this, and the ps3 does output this? then i obviously would need a new receiver, correct? or since i mainly use my setup for gaming and blurays, would it be useless anyways?

[crackinhedz]

yeah, you would need a new receiver with HDMI v1.3 deep color/x.v. color

....but I don't believe any real source material is making its way to common use anytime soon. I also don't think bluray can/will be using it either, someone correct me.

ok thanks for your help. If its not being used currently, then there is no reason for me to upgrade my receiver since it does everything else i need it to (LPCM Lossless Audio and 1080P) Thanks again...

[crackinhedz]

yeah, I wouldn't worry about it until the time comes.

i recently was reading up on this and what i read so far, is for now the hd camcorders that advertise deep color are more just a marketing ploy than actual deep color output, due to the additional size of the video with the extra color information, and the capture capability of the hardware. hmm i still haven't found solid answers though.

[Pelican170]

well thanks guys. if any other info comes up, please post...

I posted about this same question a few months back. I saw where one of the Pioneer BD players supported deep color!

tell me this...how is your tv suppose to show deep colors when the blacks on it are gray lol

Funnily enough, deep colour isn't about colour - its about depth of modulation.

The hole deep color thing is a marketing ploy, it's a feature that is included in players & not in BD's. It's worthless. Don't get suckered into thinking otherwise.

I think its XV colour thats probably the biggest marketing scam. This relates to the colour gamut, which is analogous to envelope, or bandwidth. XV colour isn't supported by blu-ray or any broadcasts, so the information just isn't there in the first place.

Deep colour is a bit different to my mind, as it's more analogous to bit-depth, or over-sampling. This is about the level of resolution of the video that has been captured:

Frames per second;
Lines per frame;
Pixels per line;
Bits per pixel.

Each of these parameters works within the video envelope, and can interopolate between the captured data. For example, scaling can increase the number of lines in the frame, or frame interpolation can increase the frame rate from 24fps to 96 fps for example. These processes don't increase the amount of infromation that was captured, but they can make the resulting video image smoother.

Spatial upscaling is well established, and temporal scaling is getting there. I dont' see any reason why "deep colour upscaling" for want of a better experession, shouldn't be able to scale 8 bit video up to 12 bit video. There won't be any more information, but the video may look smoother, with fewer graduation steps, as a result. Pioneer and Sony are beginning to do this, and if processors, amps, receivers, recorders and displays can handle deep colour, then why not?
