I thought Blu Ray was the biz, so whats this for, may be I am tired, it's not making sence.


Panasonic DMPBD60

PHL Reference Chroma Processor Plus is a high quality image-processing technology developed by Panasonic to precisely process each pixel of the Blu-ray Disc video signal in the vertical direction. It reproduces colour data with twice the accuracy of conventional systems to keep colours faithful and sharp. Panasonic's developed high-precision 4:4:4 signal technology also processes each pixel of the Blu-ray Disc video signal in the horizontal direction, to complement vertical direction processing. When viewed on a VIERA high-end model, which features 4:4:4 signal compatibility, it recreates images with the original film quality to further enhance movie enjoyment. Because these models are compatible with the VIERA CAST function, you can access YouTube, Picasa, and other Internet sites from the special VIERA CAST screen. YouTube lets you watch the newest video clips, and Picasa lets you view Web-based photos. You can also check weather and stock information on other sites.

Nearly all video recording systems, indeed coding systems, throw away colour detail on the grounds that the eye cannot resolve it anyway.

It looks to me as though Panachronic have spent some time in designing a better way to re-constitute the missing detail and are trying to sell it.  There are people out there who like to spend their hard-earned (or nefariously-gained) on such devices so good luck to them.

In the instances where colour detail is needed (such as chromakey, blue/greenscreen. CSO or whatever you like to call it) producers will probably use a recording format that preserves the information rather than re-create it.  HDCAM SR for instance or direct HDD recording.

As you say seems they have done some home work and want paying.

Just makes me feel that Blueray is not quite as good as it 1st seemed.

The bandwidth and storage required for full video is enormous.  Whilst it can be managed uncompressed the arguments for compressing it are very convincing. Seeing as how we are desperate to clog up every available artery and repository of digital real estate with data, the compromise is continually there: "How much compression can I get away with?"  The answer is similar to "as much as possible before the slightly aware notice it".  With images, lossy compression is acceptable and allows vastly greater compression ratios than any currently known lossless algorithm.

So.... I was very saddened to view some BBC HD stuff in a local department store the other day that had compression artifacts crawling all round the BBC logo in the top left corner.

Going to Blu-Ray.  It survived a format war with HD DVD which was primarily about the length of recording you could store on it!  With your perception, disappointment was inevitable.

Cheers for the explamation, it seems to be sinking in slowly.

At the end of the day - the source material is compressed and 4:2:2 so all they can claim is that they make the most of that. Let your eyes decide how good a job they make of it, I guess.  :-/
