Hello
Thinking of buying the Apple Tv for streaming JPG photos to my Sony Ex720 TV. But the TV is very selective on color profiles of JPG (won't accept profile 4:4:4).
So which profile will be submitted from Apple TV?
Thank you for answer.
Best regards

The TV will have nothing to do with it.
The JPG will be decompressed and rendered by AppleTV and output over HDMI according to the prevailing HDMI setting on AppleTV.

The real question is will iTunes and AppleTV handle the 4:4:4 profile JPEG I guess. This is to do with the 'block profile' fro compression rather than a colour space for colour gamut isn't it?
What's the source?
That was what I was thinking AC, it's something I'm not too sure about, I just assumed whatever the source it would be decompressed to 4:4:4, but was thrown by the TV apparently not doing 4:4:4. Also I always thought that the HDMI output just toggled between YCbCr and RGB and the high and low referred to contrast.
Hello again
Hmmmm
If I understand the answers correctly Apple Tv feed the Sony TV with a 4:4:4 signal and then I won't be able to use the product.
So can this signal be tweaked/changed in settings or do I have look elsewhere for a media server?
Please advise.
best regards

I was sort of thinking allowed, my assumptions don't seem to fit your observations regarding your TV, I can't see Sony producing a TV that doesn't work with rec 709, so maybe my assumptions are wrong, what makes you think you're tv has problems with 4:4:4.
Reason for 4:4:4 fault
Have taken some pictures with a pocket camera which automatically saves in jpg format on the memory card. At the same time I took some pictures with Dslr which saves in raw format. The raw files were modified in Lightroom and saved as jpg. All jpg files were copy onto a fat32 usb stick and the dslr images wouldn't show but the pocket camera images no problem.
Sony hinted at differences in color profiles and the files were checked in a program recommended by Sony. So at the moment it isn't very funny to show pictures on ipad or pc monitor when you have a new tv standing.
So any feedback are welcome.

Any chance the processed DSLR images are too high a resolution for the TV to handle?

Agh I see. The TV when processing the images is having a problem with JPEG images for whatever reason. The Apple TV won't send the TV a JPEG image, it will generate a video stream using your slideshow settings and the TV will receive the info in the same way it receives it for a video.
Of course I can't absolutely guarantee the Apple TV won't have a problem with the JPEG image, but I sort of doubt it. If you want to email me one of your photo's I can always try it for you.
