What hardware do you think is required for H.265? Please elaborate as to me it seems like you have no clue as to what your talking about.

Well "required" probably wasn't the best choice of words, what I meant was it lacked H.265 acceleration hardware.  I clarified in the next sentence that they could do a software encoder/decoder, though I don't think it likely.  H.265/HEVC was finalized on January 25, 2013 and the specification was formally ratified as a standard on April 13, 2013 but the GCN architecture the PS4/Xbox One is based on came out a year before that.  I don't believe even the latest nVidia PureVideo (Feature Set E from Maxwell) or AMD UVD 4.2 have support for H.265 yet.

 

In any event the point of my post wasn't to debate what encoding formats the consoles can and will support.  The overall point was that System Update 2.0 would not come out on or before the 7th as the post I replied to stated and it didn't.

H.265 is a compression format, it doesn't require any special hardware to decode...

H.265 is a compression format, it doesn't require any special hardware to decode... 

H.265 is the successor to H.264 both are Video compression standards.  Is your contention that video cards don't include dedicated hardware to support compression standards?  Google AMD UVD/VCE or nVidia PureVidio/NVENC.  These are the video decode/encode hardware blocks from AMD and nVidia that is included in their GPUs/APUs.  Both the Xbox One and the PS4 have dedicated hardware for doing H.264 as part of their GPUs, neither has any dedicated hardware to support H.265, which was my point.  Again, in theory, Sony could write a software decoder/encoder and even use the GPU shaders to try to reduce CPU usage but I doubt they'd bother.

 

You can certainly disagree with my assertion that they wouldn't bother, that's just my opinion, but it is FACT that these "compression formats" are typically supported in hardware in modern electronics (from high end GPUs to mobile SOCs and HDTVs) and the PS4 lacks such hardware with respect to H.265 (though it DOES have it for H.264).  H.265 is very new and devices are just coming out that support it.  I don't believe any AMD or nVidia Graphics Cards currently support it (though they both have extensive support for H.264, its predecessor)

      I'm not unblocking my camera for this crapola. Sorry, Google.

      It seems these features are for Business Profiles

      Ummmm that is what is it supposed to do. Just turn if off in settings if you do not want it analyzing your open tabs. Chrome does the same thing with Gemini. Sarfari will do the samething after Apple's AI and even more so with the release of their 27 versions that is now powered by Googles LLM/ML models. Understanding why it is doing it and how it can help you vs jumping to some conspiracy theroy is a much better approach. As long as it can be turned off, all is good. Yes the default should be off but the a lot of people would never discover these features.

      Just another reason (aside from many others) not to use Edge. Firefox 153.0b5 DEx64 has a similar feature added recently in prior builds that I will turn off at some point when I get around to it. It's the new "Something looks suspicious" page that pops up here and there. It cleverly hides itself between web pages that I've actually visited; as a result, you know, of selecting a web page and telling the browser where to go. The interesting thing is that it does not produce these warnings from pages that I, as the only intelligent user of the browser in my system, have ever directed the browser to open! What seems to be happening is that the browser looks at all the goofy ad links on a web page I do actually open and selects one that "looks suspicious" and then creates the "something looks suspicious" web page, which is neatly inserted, as mentioned, between web pages my RB ("real brain") has directed the browser to load in a session. The thing is, I usually look at links I am considering to follow before I ask the browser to load them, and in cases I have noticed where the link does indeed look suspicious, most of the time I will choose to not follow the link at all. Doesn't everyone do this or something similar? I am picky about what I voluntarily load... (I don't like links that start off fine, with a site designaiton that seems normal enough but then is followed by indecipherable alphanumeric strings many, many lines long, etc. I tend to reject those because they look suspicious. They may not be, but I don't care... I'll stay with Firefox, of course, if for no other reason than they usually let you turn off the junk you don't like. And because it isn't Edge... But at some point Microsoft will come to realize that putting your bookmarks on the left side is a Good Thing for a lot of people, just as Microsoft discovered when it had the bright idea of nailing the Windows taskbar to the bottom of the screen, when for decades Microsoft browsers had left that placement up to the user. They have finally reversed the obscenity of that decision. Finally.

      Google was using the old CATPCHAs data to train their LLMs. What is the say they won't use this camera data of users to train their LLM? these companies need some strict regulations!
