从网上找到两篇关于音频规格和高清播放机芯片的文章。
希望能解答一些初学者心中的疑问,让大家能真真购买到最适合自己的高清播机。
HD Media Player Chipsets
This page gives some background to the history of Media Player chipsets and lists the key players associated with each.
The first chipset to be capable of decoding 1080p full-HD video was the 863x, clocked at 300mhz, from a company called Sigma Designs. The Sigma 863x spawned a whole series of Media Players from early 2008 onwards. It was these players that kick-started the Media Player revolution. Manufacturers released machines with modified versions of the original Sigma firmware, so the Sigma 863x machines are not identical. There are differences in all areas, from user interface to marginal decoding performance. Ultimate performance will always be a combination of hardware and software.
The Sigma 863x is now being superseded by newer chipsets, aimed squarely at the growing Media Player market. Limitations of the Sigma 8635 such as slow user interface, limited DTS support, and just general lack of power are being addressed in a new generation of chips released in 2009.
Sigma 863X, CPU: 300mhz
Popcorn Hour A-110, WDTV, Dune HD Base, Egreat EG-M34A, Myka, Tvix M-7000A, QNAP NMP-1000 and HDX1000.
The Realtek 1283 / 1073 chipset range appeared in mid 2009 and is clocked between the old Sigma 863x and the newer Sigma 864x/865x. The Realteks use one CPU, clocked at 400mhz. A flood of cheap Realtek based Media Players have arrived through 2009. These have included the 1073 based ACRyan PlayOn, ASUS O!Play, Mvix Ultio, and the 1283 based Xtreamer, amongst many others. The 1073 is simply the 1283 with some DTV functions stripped out, they are otherwise the same chip providing the same performance in a Media Player. The only hardware performance difference amongst the Realteks is that the Xtreamer is clocked at 450mhz rather than 400mhz.
The Realtek chipsets provide fast and reliable performance at a low cost. These players can cope with all Media files you are likely to come across with only abnormally high reframe files or some HD audio formats providing any problems. The one big problem common to all the Realteks is a fairly unattractive user interface. This should be fixed in future software updates.
Realtek 1073/1283, CPU: 400/450mhz
Xtreamer, Myix Ultio, ACRyan Playon!HD, Asus O!Play, DViCO 6600, MediaGate M2TV, Brite-View CinemaTube and IcyBox IB-MP305.
Sigma released both 864x series and 865x series chipsets in late 2009, with the first player featuring the 8643 (Popcorn Hour C-200) shipping in September 2009, and the first 8655 players (WDTV Live / Eminent EM7075) arriving in October 2009.
The Sigma 864x and the 865x are related and similar chips. The 864x has Blu-Ray capability and is the more powerful. It contains a 667mhz CPU and a 333mhz IPU (image processing unit), 2* HD video decoding, and three 333mhz Audio DSPs. The 865x lacks Blu-Ray support and uses a 500mhz CPU / 333mhz IPU, 1.25x HD video decoding, and one Audio DSP.
Sigma 864X, CPU: 667mhz
Popcorn Hour C-200 and Dune HD Base 3.0.
Sigma 865X, CPU: 500mhz
WDTV Live, Eminent EM7075 and Datastor Media Player
Even at this early stage, it is apparent from testing that the new Sigma chips are more powerful than both their 863x predecessor (much more powerful) and the competing Realteks. Less testing has been done on the 864x because it is only available in one player with limited availability, however a decent amount of testing has now been done on the 8655. All these tests indicate that this is hugely impressive chip, capable of dealing with anything you throw at it in terms of reframes/bitrate. Other problems from the previous generation have been solved, the user interface is now much quicker, and DTS is supported.
In late 2009 Intel is expected to release it's own new media processor, the 800 MHz CE3100. This chip promises to take everything one stage further towards a single integrated home entertainment hub with computer functions. In some ways it is really just a Pentium M rebadged. It will be interesting to see how this chip compares (including for price) when devices are released utilising it such as the Conceptronic Yuixx.
Intel CE3100, CPU: 800mhz
Conceptronic Yuixx
2009 has seen many Media Player chipset developments. The old Sigma 863x is now a relic of the past, with new more powerful and cheaper chips being available from both Realtek and Sigma. The players using these chips are all at an early stage in their development so it is impossible to make any final judgements. What we can say though is that both the new Realteks and the new Sigmas are capable of playing back flawlessly almost any file you will find in the wild. In this sense, the choice of which to buy has become slightly irrelevant. Of more concern should be the usability of the device and it's price. In the near future we would expect the range of HD formats being used to become much more narrow, largely negating the format issue. Interface and additional web-based services will become much more important to the bulk of users. |

各位大大..小弟我有个疑问想请教你们..
对于full HD LCD TV来说PC input和blu ray/dvd player input的解晰度会有所不同?
最近看上几台full HD的lcd.可是在resolution那边有些疑问..
拿philips的lcd来说,它的resolution spec如下…
Computer formats 640 x 480, 60, 72, 75, 85Hz, 800 x 600, 60, 72, 75, 85Hz, 1024 x 768, 60, 70, 75, 85Hz, 1280 x 768, 60Hz, 1280 x 1024, 60Hz, 1360 x 768, 60Hz, Via HDMI/DVI input,
Video formats 480i, 60Hz, 480p, 60Hz, 576i, 50Hz, 576p, 50Hz, 720p, 50, 60Hz, 1080i, 50, 60Hz, 1080p, 24, 25, 30, 50, 60Hz
是不是说连接PC的话,就算是用HDMI cable,它最高的resolution也只能去到1360 x 768, 60Hz(还低过我的HD ready lcd monitor的resolution,1600X900),而不是1920X1080P full HD的resolution?
这样的话就算从PC 播放HD movie,也没有HD的效果了..对吗? |

LCDtv的computer format所指的是从D-sub连接器(PC input)输入的信号。。。
假如你用VGA线把电脑连接到LCDtv(PCinput),resolution一般只能到达1360x768。
然而假如你是用HDMI线把电脑连接到LCDtv(HDMIinput),最高的resolution就取决于你的GraphicCard支援多高resolution。
假如电脑硬件(graphicCard)支援超过1080p,根本没有所谓的HTPC播放不到full HD效果。 |

谢谢大大的解释….这样我就放心了…
所以说只要你是full HD lcd tv,然后用HDMI来连接..只要你的显卡(我的是ATI HD5850,resolution打1920X1080应该没问题)可以支援HD resolution,基本上就没有问题了…对吗..
可不可以这么说..假如是打算用HDMI来连接PC..那在选择LCD TV时基本上可以不用顾虑computer format 这一部分的spec了..… |

画面较容易调,只需要调你的GraphicCard。。。。
但是声音设置方面就较复杂, codec,driver, OS, 播放软件(PowerDVD(播Blu-Ray disc)) ((PureCodec(播电影案)),Output(S/PDIF或HDMI),5.1或7.1,内解或bitstream到HDMI扩大机器,HTS(audio input)能解DTS吗,等等。。。。
如果有时间和感兴趣想更深入研究,可以到Myav,CHDtv, HDclub爬爬贴。

声效方面暂时要pending先..
因为没有budget出HTS了..
所以应该只是用TV的speaker还是我那普通的2.1speaker来顶着先…
下次存够$可以改善声效时再来请教你们… |

请问下HTPC的dvd rom有没有办法做到video upscaling的功能?
需要什么硬件和软件的配合?
以小弟我的硬件来说..ATI HD5850用HDMI连接去full HD lcd..DVD ROM只是普通的LG DVD-RW.
这样的硬件做的到up-scaling吗?
软件方面是需要特定的DVD player软件? |

为什么需要DVD upscale?哈哈, 考虑直接装一个BDdrive啦。
PowerDVD9具有DVD Upscale功能。

BD Drive贵到...少少整千块...暂时不值得玩..
C4卖的Philips BD player BDP3000型号..RM599..在考虑着要不要入手..
不过好像有region code的..

老李,我在等你最新的HDX上画呢。
对了,HDX1000竟然在12月时释出了最新firmware呢,我还以为他们已经放弃了,毕竟大陆市场太竞争了,新一代的产品接着出,旧的就自求多福了,可是HDX还是很不错的企业,毕竟他们的产品是外销到欧美的,support是建立企业信誉最重要的一环了。用了那么几个players,HDX1000我非常满意-为什么呢,它是唯一(不要拿那些天价货来比)在同等级产品中唯一能bitstream DTS和DD HD audio的了,而且在播放BDMV上(多个m2ts)是最棒的了。wdlive在播放BDMV时只会挑最大的来播而已,可是HDX1000是从第一个播放到最后一个的,对于它的能力我真的很讶异。
你的最新HDX-BD1什么时候来站台啊 |

Frankling兄,你果然是一个播放机收集者。HDX-BD1确实是来势汹汹,听说接上无线键盘和鼠标器就能上网。
但我还是较注重片源,好的播放机不需要常常更换年关近先办年货。你已找到货源了吗?小弟朋友正在为我找货源。 |

你说得对啊,年关将近,办年货才重要啊,不过如果把播放机当年货来办呢-乘年假好好看个高清,把LCDplasmaTV的潜能发挥到极致,顺便把好东西跟来拜年的亲朋戚友来分享!!! 不过我应该不会要入BD1了,觉得好像跟1000差别不大,反正有bd player了(对了我的player也可以play mkv),BDrom对我来说性价比就不高了,function也少。。。
最近还在收集remux和iso吗?我有点放弃了,我这里的网速太慢了。。。 |

希望今年拜年来的亲朋戚友没有再对我的高清资源充满兴趣,不然小弟又要大忙一段时间。
小弟是小水管Remux和BD ISO是没有可能,只能期望从同好间交换获得。
最近都在重点收集些穷人的玩意4G左右的720p.mkv案,除非遇到些较值得收集的才拼命收集1080p版本。
电脑power supply都更换了两次,如今改换轻松自载应该可以让电脑引退。
速度上没有变,但是现在能在office远程"收集"与控制,再加上24小时不间断,希望能早日一尝小地主之梦。 |

此盒只需两百左右不到NAS一半价钱.
最近没有budget扩充仓库,所收集和生产的资源又越储越多。
哈哈,与你一样享用资源都没时间,感觉上是为了生产而生产。
现在又买入新机器,把生产时间变换成全日制。。。。
ape兄,有否发现硬盘价钱有向上趋势?扩充仓库的预算又要提高。
Avatar以及2012实在精彩,只是后者比较雷声大雨水小,而风云2我就错过了。
有否发现最近电影院的画面很模糊,特别是那个"吓到笑"整个影片暗暗的,是我的视力出了问题吗?
(注意:此贴纯粹分享播放高清经验和乐趣,不鼓励不提倡非法下载,购买或出售片源。请大家自行决定获取片源的途径。多多到电影院看电影) |
