来自主题: HiFi版 - 最近的一些心得
电脑分辨率指得是显示器的分辨率,那确实是高,但是当你选择其他图像输出方式,例
如连到电视机或投影仪时,图像显示的会是你实际显示器材的native resolution. 一
般电视是480i, 所以你即使使用HD/BD碟机输入1080p的信号,它也会在电视机的内部由
一定的chip来downgrade它,你实际看到的是480i的东西。 高清电视或投影仪也一样,
它内部会有运算模块来保证即使输入的是standard 480i(例如DVD)信号,显示出来的也
是它的native resolution (如720p, 1080i, 或1080p)。 upscalling DVD player内
部也有这么一个chip, 来对DVD信号进行运算再输出。 然而很多高清电视用的这个
chip并不是很好,就像有些便宜的upscalling DVD player效果不好一样。 这时如果用
一个好地scaller, 直接给显示器材输入它native resolution的信号,就会比一般的
DVD机效果好。 Oppo用的就是业内最好的chip, 其他品牌如Denon用同样chip的机型价
位要高好多。

来自主题: Living版 - 买HDTV的几个考虑
供大家参考:
(1) plazma的对比度和颜色,dark black是没的说,绝对比LCD好.但是对于现在的节目来
说,还是LCD比较好,因为电视上有太多480i,480p,4:3的节目.用plazma看,如果不做水平
拉伸,就有可能burn in.拉伸看着难受,多了个顾虑.
(2) 1920x1080意义不算非常大,当然看1080i的节目,还是要比其他的好.但是如果电视
不大也就无所谓了.我觉得hd-DVD和blue-ray DVD的制式之争得过几年才平息.所以短期
内没什么节目可以充分利用1920x1080.就算你买了hd-dvd,你也找不到足够的片子.除非
打游戏,另当别论.
(3) native resolution只是一方面,老的模拟的电视效果那么好,只有480i.颜色数目,
对比度,scaler的性能都要综合考虑.所以不要买太便宜的电视.便宜的电视用的
processor太差.好的scaler非常重要,如果你经常看STV,DTV(480i),EDTV(480p)的节目.
(4) ATSC和QAM tuner,ASTC是用来收 off-the-air信号,QAM是cable

把一个老贴转过来.
顺便说一下关于DVD upconverting的问题.
upconverting 还是有很大差别的.大家都知道DVD是480i,所以以为只要displayer高于
480p就没有差别,这是误解. 在HDTV上,好的scaler能把边界和细线scale到native
resolution上,绝对不是简单的放大.颜色处理也是类似.具体的设计细节各个厂商可能
不太相同.大家一定要实验一下.
Upconverting DVD playerHD输出(780p..1080p)并不一定会比(480i)输出好.这是因为
DVD player的scaler不一定比HDTV的scaler好.
HDMI不一定比component好,因为HDMI的实现很多差别,有的芯片很buggy, 一定要实验.

I only used component video. I remember that when I first got it, I compared
480p and 480i in game(DOA3), 480p is noticably sharper. I assume S-video
should be comparable to 480i on component input.
Surround sound is another story. The effect blows normal stereo system away,
in both games and movies. As you already got the home theater system, you
should upgrade simply for the audio part.

not sure about 标配视频线,for 480P you need a component cable, the normal cable which cames with my WII only supports 480i. Also, it's only very
small difference between 480i to 480p (at least for me).

把声音信号跟视频信号分开送就行了
图像插值,就是把比如480i的信号提升到1080p的分辨率,让电视机来做就行了,除非
电视自带的不够好。

昨天刚看到的,就是:
bring your own whiteboard dry-erase markers. They sell pencil-thin ones at
office supply stores, whereas most companies (including Google) tend to
stock the fat kind. The thin ones turn your whiteboard from a 480i standard-
definition tube into a 58-inch 1080p HD plasma screen. You need all the help
you can get, and free whiteboard space is a real blessing.
我觉得最好买那种笔帽上自带小板擦的,昨天用了一下,很方便
还有如果想练白板推荐costco家的白板set,$29.99好大一块,还带n多附件,其中就包

床上看,就全是马赛克了。
我知道22.2应该播的也是fox13。这个台信号效果倒还行,不过只有480i,比13.1的
1080i 还是粒子粗多了。
新一季的24小时就要在fox开播了,下半年还要指着fox看seahawks。所以这个台不能缺

大前天发现这个游戏的,发现正是这几天上市,今天周末顺便去买了个回来。
在PS2上,用Logic G25方向盘,玩了一个小时,有点失望。
以前在电脑上玩过若干代NFS,从二代开始玩起,最后是Underground 1和2,
一直都觉得还不错,很好玩。
一年前买了个PS2,主要是玩Gran Turismo 4 - the Real Driving Simulator,
为此配了个G25方向盘。开始喜欢这种'Simulation'风格的,不再玩NSF之类‘赛车游戏’
买了这个ProStreet也是听说是NFS以此从纯‘游戏’向‘接近现实’方向靠拢。
(其实以前的Porsche那一代就试图靠拢过,我觉得太难玩了,放弃了)
开始说回ProStreet,玩了一年的GT4还没玩厌,自然忍不住要拿这两个来比,
1。画面,同样是在代表若干年前水平的PS2上,GT4可以到1080i,ProStreet只有480i,
这一下子让我太不习惯了,速度快了,画面分辨率不够真的会眼晕。
也许PC, xBox360, PS3上的效果会好些,EA懒得像PI做GT4那样尽力挖掘PS2潜能罢了。
不过,同样PS2上,GT4
