These are rather confusing times in the world of home theater and even next-generation gaming. With the move to new high-definition optical disc formats in the way of HD-DVD and Blu-ray, hardware makers and studios are utilizing some rather stringent anti-piracy means in order to prevent movies from being copied, especially in HD. The side effect is that these means will prevent some users from being able to take full advantage of the formats, and the details behind all of this is causing quite a bit of confusion.
高分辨率DVD（包括HDDVD和BD）的出现让现在的消费者很迷惑，有谣言关于高分辨率电影在本世代电视无法显示真正高清晰，由于版权保护等等原因。
Both HD-DVD and Blu-ray employ an AACS (Advanced Access Content System) copy protection scheme that, to keep things short and (somewhat) simple, will down-scale HD content to a non-HD resolution if it isn't displayed over an HDCP-compliant HDMI connection. In other words, hooking up either of these formats via component connections won't cut it for true HD playback, at least in the future. Luckily, studios behind both formats have said that they won't ship their first batches of movies (possibly for a few years) with the scheme enabled to give users time to shift over to HDMI-enabled televisions, but this still leaves many questions in the world of gaming, specifically with regards to the PlayStation 3.
HDDVD和BD都有AACS反拷贝系统，如果没有HDCP-兼容的HDMI来接电视，不会有真正高清晰，不过，这只限于电影！！还有一点，现在或1/2年内出的高清晰DVD电影，这一点还没有执行！！为的是电影发行商考虑到现在HDCP-兼容的HDMI电视还不普遍。这就是说现在买的HDDVD电影可能可以用普通的component或VGA，DVI达到完全高清晰，只要你的电视支持！但5年以后，你就必须用HDMI+好电视才可以了？（我本人对这点表示怀疑！难道某年某月出的某个电影就突然不能播放了？）
The main concern is whether or not gamers will be able to play PlayStation 3 titles in high-definition if they're "only" using component cables. Luckily, Blu-ray's copy protection scheme should have no impact on gaming whatsoever and PS3 gamers will be able to enjoy their next-gen systems at HD resolutions with any sort of HD-capable connection. This means HDMI, VGA, DVI and component connections would all work in HD, assuming these connections are all supported by the PS3's "Multi AV-out" port. Composite and S-Video would only work in 480i, of course.
然而，这一点不会对游戏玩家造成影响，因为PS3/BD游戏的输出画面没有被拷贝/盗版的价值，所以你可以用任何的接口HDMI/VGA/DVI，无论现在或将来，来达到高分辨率的输出，只要你的电视支持。所以，不需要等到真正支持1080p video-input的电视出了，只要是支持1080以上的的电脑LCD都可以用来玩1080p的PS3游戏。这倒不失是中国万家的解决方案，毕竟国内的相看HD电影的少，玩游戏的多，所以买个1080p的电视还不如买个便宜的29寸的1900x1080的液晶显示器。
The technical reason for this is that Blu-ray's AACS system is both hardware and software based, and any protected software will need to contain an Image Constraint Token (ICT) to essentially turn on the protection scheme. In other words, this is optional and whoever authors the media has the option of utilizing the AACS scheme or not. It's very much like how some VHS tapes have Macrovision and some don't.
BD的AACS反拷贝有硬件和软件两部分，所以游戏发行商不会在游戏中加入类似的软件保护。
后面的不重要，大家可以攒钱买支持1080线的LCD显示器了。至少玩PS3够用了
You won't need these for HD gaming.
In practice, it wouldn't make any sense to copy-protect the image output of a videogame. With movies, this makes obvious sense as the movie is wholly visual - that's its purpose and only existence (well, plus audio, of course). With gaming, the visuals only work to parlay the experience of interaction, which is what publishers are selling. If people stopped buying games and just started downloading 12-hour video walkthroughs, this might be a problem, but we don't foresee that happening, well, ever. It's possible that a company like Square may want to apply something of this sort to its cutscenes at some point in the future, being as so much money and production time goes into the making of these cinematics, but even this is rather unlikely.
There are rumors and rumblings that some older sets, HD or no, will simply not work with the system at all. This is not true whatsoever. It's true that you may not be able to play some future Blu-ray videos in HD resolutions on these sets, but they'll be perfectly fine for gaming. A good, basic rule of thumb is that if you can display HD video from any other component in your home theater, be it your cable box, Xbox 360 or whatever else, then it'll work fine with PlayStation 3 games. And even if you have some 1976 set that barely works, you can be sure there will be some way to get a PlayStation 3 connected to the POS.
With all of this confusion, some folks may wonder why Sony has been so outright steadfast about including Blu-ray in the PlayStation 3. Aside from simply making things confusing, the format has also played a large role in the system's delay to November of this year.
Really, there are multiple answers to this. First and most obviously, gaming benefits most from Blu-ray's massive storage capabilities, with dual-layer discs capable of holding up to 50GB of data. Dual-layer HD-DVDs can store about 30GB by comparison while dual-later DVDs can store around 9GBs. The Blu-ray Disc Association is currently experimenting with eight-layer discs capable of holding a whopping 200GB of data. If that's not enough room for you RPG gamers out there, we don't know what is.
More importantly in Sony's long-term plans as an electronics giant, however, is Blu-ray's role in movies. While Blu-ray will likely do fairly well on its own (once the prices come down to more consumer-friendly levels, anyway), Sony is using the PlayStation 3 to act as something of a Trojan Horse to get players into people's homes. If the PS3 is roughly as successful as Sony's past consoles, that would mean somewhere around 100 million Blu-ray players in homes all over the world in around five years or so, not counting standalone players.
Being as Sony pioneered the technology, should Blu-ray win out over HD-DVD and supplant DVD as the standard in home video, the company stands to make a fortune raking in a small percentage for every Blu-ray disc sold, similar to how it currently takes a licensing cut for every game sold.
Now, one other question that people have is whether or not the PlayStation 3, and all other Blu-ray players for that matter, will be able to play their current DVDs and CDs. Yes, it will. In fact, just about the only media type that the PlayStation 3's Blu-ray drive won't be able to read is HD-DVD. There's no word yet from Sony on whether the system will up-scale DVDs to HD resolutions, though we'd be a bit surprised if it didn't. Although, the Xbox 360 doesn't so...
That should wrap up most of the pending questions that people seem to have about the PlayStation 3's Blu-ray capabilities and any adverse connectivity effects its copy-protection scheme may bring with it. Hopefully Sony will announce the last few tiny details at its press conference at this year's E3, like the exact drive speed, DVD up-scaling and so forth. But regardless, rest assured that you won't have any problems playing games in high-definition on your current display.. |
