发帖数: 60932 | 1 Always browsing through the Target aisles in the Electronics dept. Price is
not to shabby for the size and specs, I believe. Unfortunately, there was no
display model to look at.
Looking through the web, seems like $699 was the price during the Black
Friday deals.
The temporary cut/sale is valid from 1/1 - 1/14. Target online reviews are
at 4.5/5 stars. I've attached to this post some pages from the TV manual, if
you're curious.

他说的是一段你不知道的历史，80年代日本投入了上百亿美元发展世界上首创的高清晰
度电视系统，从摄像机到电视台到卫星到终端电视的全部系统都已经完成并以开始试播。
不过美国轻轻推出一个数字压缩技术，所有的投资全都打了水漂了。
数字电视的核心技术日本没有领先过，都是美国在主导，最早的数字高清国家标准是美
国的ATSC，世界上最早淘汰模拟电视普及数字高清电视的也是美国。 |

智能手机的大规模普及，好像让中国人得了“Wi-Fi依赖症”。在家不能没网络，出门
不能忘手机，移动互联网改变了社会形态和人们的生活方式。但是，我们真的能让手机
放心大胆地连上它吗？
2017年10月16日，Wi-Fi安全协议出现重大漏洞的新闻引发关注，根据一家安全研究机
构发表的报告，用于保护Wi-Fi网络安全的防护机制WPA2出现漏洞，黑客可以利用这一
漏洞监听到任何联网设备的通讯内容。
技术专家们对这条新闻都很淡定，因为他们已经见识过很多次Wi-Fi的安全漏洞了，只
是以前没有引发公众注意而已。
实际上，自从2014年开始，国内媒体就开始报道用户手机加入公共Wi-Fi热点后遭到经
济损失的案件。
在2015年的3•15晚会上，央视曝光了免费公共Wi-Fi存在的诸多问题，并做了一
个令人震惊的实验，主持人邀请现场观众加入节目设置的Wi-Fi热点后发自拍，然后观
众的邮箱和密码都被黑客得到了。

如果只想要SD的TV信号，最便宜的方法是捡一个录像机，那种老式的磁带录像机，VCR
机器，我现在就是这样的，VCR收电视，composite信号到投影机，RCA接receiver的TV 的
audio-in。
如果想要HDTV，要么出钱搞cable公司的cable box，要么HDTV tuner，通过电脑连
receiver。今天刚买了woot上的ATI的usb HDTV tuner，25刀。只有ATSC tuner，意味
着只能收OTA
的HDTV信号，这个价钱，不算太差。 |

发帖数: 2209 | 16 How similar is yours to that one?
The little piece of information useful for you is that nowadays, HDTV comes
in two flavors, Over the air, and Cable.
To enjoy the former one, you need a tuner or TV equiped with something
called ATSC tuner, for later one, you need QAM(or clear QAM for unencrypted
signal) tuner.
So, the answer to your question, is that check your tuner,
if you see QAM tuner, you should able to watch the HDTV with your current
setting, otherwise, get a different TV tuner, actual T |

发帖数: 22 | 18 If you are trying to get Dish(DirectTV/DishNetwork)'s HDTV programming,
you need to get a HD receiver from them(like DISHNetwork's Dish 811 etc)
and subscribe to their HD service.
If you just want to get local broadcast in HD:
1) go to amazon.com and search ZHDTV1 antenna, you'll get one for about
$20. Use www.antennaweb.org to check your distance from towers,
hopefully you are not too far away, otherwise you need bigger/outdoor
antenna. Then you need to do ATSC/8VSB scan to get OTA |

synopsys (向回帖者致敬) 于 (Fri Nov 25 21:02:50 2005) 提到:
如果不用cable/dish company的话，有两种方式接收HD频道：
1. over the air。是不是需要HDTV有个ntsc/atsc的tuner？
2. 从cable中收。是不是需要HDTV有个QAM tuner？是不是可能需要HDTV有个CableCard
Slot？
大家有没有人用comcast cable去收HD channel的？不是说自己另外付钱的那种。如果只
能用额外的天线收，那需要电视有两个天线输入（HD + Comcast cable package)，或是
一个天线输入加dish/DirectTV的box，要不然切换太麻烦了吧？
今天的37寸syntax好像只有第一种tuner，一个天线输入。它本身也属于高档指标（虚假
？比如8ms），低档品牌/design货。

发帖数: 2610 | 20 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 |

发帖数: 4125 | 21 If your TV (most newer one do) have ATSC tuner, you can get a lot of un-
scrambled channel, they will not show up in the correct channel number (
like with the set top box), they will just appear all over the place if you
do a scan of the channels. Depending where you live (some area are not
service by comcast before, they are just bought out by comcast), this un-
scrambled channel may not exist much longer, but depends where you live and
their exist cable tranport system. So this is big YMMV. |

发帖数: 4125 | 23 You must be using the built in ATSC turner to scan for the channels, you
should use the cable box to select the channel, it will match the listing.
Some TV will let you assign lable to these channel, so once you do that, you
can match the TV guide to the channel lable, some cheap TV does not have
this option.

你带回去的话，没法接受cable或者air的信号，只能当外接显示器用。
不过现在国内很多小区都有自己的机顶盒用来接收cable的信号，这样的话你就可以用
这个电视连到机顶盒上去看电视节目了。
输出信号的质量要看机顶盒有没有HDMI的输出了，要是就是一般的S-video信号，那就
算了，牛刀杀鸡了。 |
