PlayStation 4和Xbox One都已经发布一年了，但是对于索尼和微软来说，也是时候考虑推出新版本了。按照此前的套路，两家公司很可能会推出更加轻薄或时尚的功能改进机型。不过知名视频网站Netflix却预测，下一代主机应该会支持4K分辨率。《赫芬顿邮报》在CES 2015期间的最初报道是，Netflix首席产品官曾透露，索尼已承诺为PS4推出支持4K的硬件版本。
本周，《福布斯》希望更深入地挖掘一下，但是Netflix似乎不太愿意透露更多的细节。随后，记者们还向索尼和微软进行了求证，不过两家公司都拒绝对此发表评论。


New versions of both the PS4 and Xbox One will released later this year, Netflix has said.

Chief product officer Neil Hunt told a press conference, as reported by The Huffington Post, that Sony has “promised” a PS4 hardware revision that will increase its maximum video output to 4K.

When contacted for clarification by Forbes, Netflix said that while, according to the site, it “clearly it isn’t in a position to speak definitively on Sony’s plans, [Hunt] believes that when both the PS4 and Xbox One consoles do their traditional two-year hardware refresh (which would be due around October or November) they will add the necessary components to deliver 4K video playback”.

Both Sony and Microsoft declined to comment on the claims, although Sony did say: “Support for high-resolution 4K output for still images and movie content is in consideration, but there are no further details to share at this time.”

Back in 2013 Sony announced a 4K video service for PS4, although nothing has been heard of it since the console’s arrival. Sony Electronics President Phil Molyneux said at the time that while the machine will support 4K video, 4K gaming will not be possible.

Indeed, Sony confirmed to Forbes that that “the PS4 does not currently support 4K output for gaming”.

The site, however, says that both machines would need an additional chip to support Netflix and Amazon’s HEVC 4K UHD streaming format and 4K’s HDCP 2.2 copy protection protocols. Their HDMI ports would also need to be upgraded to HDMI 2.0 if 60fps 4K playback were to be offered.

UPDATE: It has also been previously suggested that Xbox One as it stands can already support 4K output and includes HDMI 1.4.

我怎么记得两个主机本来就支持4k视频和图片输出？

PS3就支持1080p60fps
但是到了PS4，大部分游戏都达不到这个水平。

要在画质上达到中低端PC的水平，分辨率和帧数就得牺牲。

你看原文，和游戏无关

起码可以确定XOne目前的视频解码是无法支持4K的，无论编码是AVC还是HEVC。

无论XOne还是PS4，CPU都不足以支撑4K视频解码，得靠专用的硬解硬件。
顺便一提，AMD是直到刚出没多久的R9-285，才支持4K的AVC视频解码。当然XOne或PS4的VideoCodec可以不用AMD的。但考虑硬件的推出时间，PS4带HEVC 4K解码硬件的可能性也几乎是零。

我记得之前两主机方都回答过这个问题，好像是未来会用固件升级来支持4k视频播放等，x1的hdmi线还宣传是4k ready，如果没有4k输出这么宣传很奇怪

中期改款支持4K Video，而非4K Games，表想多了。

HDMI 1.4就可以传输4K视频信号，但这和视频解码能力是两回事好吧。
视频解码显然不是升级个固件就完事的，Intel的SandyBridge解码任何1080p的H264（哪怕码率超过100MBps）都能超过100fps，但就是不能解码4K，现在的Intel和NV的HEVC解码也只是硬件+CPU的混合加速解码。更何况AMD直到了GCN时期，才基本解决了1080p 60fps影片的解码性能问题……

新机型加一颗硬解芯片配合新固件就搞定了！对游戏毫无影响，完全有可能啊！你看他们都拒绝发表，明显有鬼嘛…

手机都能支持4K播放，家用机想播没什么难度吧。

游戏机硬件封闭是最大的优势

999美元主机,游戏99美元一个

先等970跌倒99美元吧
