Media Player Chipsets
This page gives some technical background to the history of Media Player chipsets.
Media Players all use a SoC (system on a chip) design whereby all hardware functions are contained within the chipset (video, sound, LAN, interface. etc). For this reason it is sensible to group players of similar chipset together as they will have the same raw performance. The differences come in firmware (software running on the chipset) although in practice firmware is often also very similar between players of the same chipset family (often being just a rebrand of the manufacturer's 'base' SDK version). This page lists all HD Media Player chipsets, grouped by manufacturer. A table allowing sorting by chronological order, clock Mhz. etc is at the end.

Sigma Designs
The first 1080p HD Media Player chipset was the 863x from Sigma Designs. It spawned a whole series of Media Players from early 2008 onwards and it was these players that kick-started the Media Player revolution. Important players based on the 863x chipset are the original WDTV and the Popcorn A-100 NMT. The Sigma 863x is clocked at 300Mhz and has now been superseded by newer chipsets. Limitations of the Sigma 8635 are a slow user interface, limited DTS support, and a general lack of power.
Sigma released both Sigma 864x series and Sigma 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 player (WDTV Live) arriving in October 2009. The Sigma 864x and the 865x are related and similar chips, with the 864x being the more powerful.
The Sigma 864x is clocked at 667mhz. The 8643 and 8642 are identical except that the 8642 is a Macrovision version allowing for the ability to play copy protected DVD / Blu-Ray. The 864x chipset is significantly more powerful than the 865x series, despite the product number being lower.
The Sigma 865x is clocked at 500mhz. All the 865x variations are similar, with the 8655 being marginally the most powerful. The 8655 uses 64bit RAM whereas the 8653 uses 32bit and the 8655 has six video DACs whereas the 8653 has four. The only benchmarks we could find give identical scores so real world performance is likely identical. The 8654 and 8652 are copy protection (Macrovision) enabled versions of each allowing for the ability to play copy protected DVD / Blu-Ray. One notable deficiency in all the Sigma chips is the inability to play RMVB files.
Early 2011 will see updates to both the 865x and 864x chipsets. The 865x range will be upgraded with the 8656, offering Gigabit LAN. The Sigma 864x range will be similarly upgraded with the 8646 and 8647 chipsets. They will offer improved performance (800Mhz), Gigabit LAN, and hardware 3D video acceleration.

2011 will also see the introduction of the next generation of Sigma chipsets.
The 865x range will then be suceeded by the 8670, offering a 700Mhz clock, 30% lower heat, and hardware 3D video acceleration. This is expected in mid 2011. Late 2011 will then see the introduction of the 8910 chipset incorporating VXP image processing for superior video quality, and 1080p 3D. This chip will be aimed at premium players and will be dual core running at 1200Mhz.

Realtek
The Realtek 1283 / 1073 chipset range appeared in mid 2009 and is clocked at 400mhz. A flood of cheaper Realtek based Media Players arrived through 2009, shaking up the Media Player market. Major players of this generation include Xtreamer, Asus O!Play R1, and ACRyan Play!On. The 1073 and 1283 are the same chip with the same performance, but the 1283 has added capabilities of recording and DTV. The Realtek 1073DA is an early release that is unable to downmix DTS whilst the 1073DD is the most common version and can downmix DTS.

Realtek 1073
Media Players
400Mhz
It was revealed in February 2010 that neither the 1073DA, 1073DD, or the 1283 can passthrough (bitstream) Dolby TrueHD or DTS-HD MA. In response to this in early 2010 Realtek started shipping enhanced + versions of it's chips. The 1073DD+ and 1283+ can both passthrough DTS-HD MA and Dolby TrueHD. Some players use a chip that is marked 1073C, 1073C+, or 1283C+. As far as we know these chips are exactly the same as the DD+.
The Realtek 1183 chipset is a cut-down version of the 1283 (10/100 LAN, 400Mhz, DVB-T). It passed DivX certification on 01-May-2009 (see here), indicating that the 1183 is of the same generation as the 1073/1283. See also the Realtek processor roadmap link below for further evidence that it is not 'next generation'.
Realtek RTD 1055, 1085, and 1185 chips are the successors to the 1073 series. All three chips run at 500Mhz so providing a small performance increase. Otherwise the chips offer the same comprehensive format support as the previous generation. The new chips run cooler than the old series, hopefully eliminating the need for cooling fans in some players. All chips run the same Realtek SDK4 Casablanca, offering a much better user experience (aesthetically, added media indexing, thumbnails..) even from the stock SDK.
The Realtek 1055 launched in late 2010 and is a non-network version with limited RAM (only 16MB flash and 128MB DDR).

The 1085 and 1185 are replacements for the 1073 and 1283 respectively. The 1185 will bulk ship in May, with the 1085 to follow in June. Both chipsets are network enabled and benefit from the addition of Gigabit networking. The 1085 has 512MB flash RAM, 256MB DDR and an integrated Flash enabled browser. The 1185 has all the features of the 1085 whilst also being DVB-T / PVR capable (so equivilant to the old 1283). Both chips have an internal PCI-Express expansion slot allowing for internal Wi-Fi and other internal add-ons.

Other Manufacturers
The AmLogic 8626H (Apollo) chipset was launched in early 2010 as a budget alternative to the Realtek 1073. It runs at 400mhz and appears to be at least equal in decoding performance to the Realtek chips whilst being even cheaper. The 8626H's main drawbacks are that it does not support lossless HD-Audio or WMV / VC-1. The Amlogic 8613 is an older Amlogic chipset used in the WDTV Mini and is unable to decode 1080P.
The Telechips 8900 series, as previously found in car entertainment systems is clocked at 500Mhz and offers performance roughly on a par with Sigma 865x chips. This chipset is used in the HDX Bone.

400Mhz
The Boxchip F10 appeared in late 2010, is SoChip SC9800 based (currently also used in some high-end portable media players), and offers full 7.1 downmix. Clock speed is as yet unknown but decoding performance has been shown to be comparable with 1073 based players. The Boxchip is a low cost solution and has allowed Media Players to be more inexpensive than ever before.
Players using Intel chipsets started to appear in late 2010. Both Google TV and BoxeeBox use the Intel CE4100. This chip runs at 1.2Ghz and reports state it is capable of 90Mbit/s h.264 video, making it roughly on a par (for h.264) with the 667Mhz Sigma 864x series. As a general purpose chip it will however be much superior.
A new chip for mid 2011 is the MediaTek MTK 8550, a chip made originally for Blu-Ray players. As such it supports Blu-Ray menus. ƉD' is also supported. File format support looks good and there are a few players upcoming using this chipset.
Other chipsets that we've come across but have little information on are MStar D7M26L/6M68/SC9800/TCC8900 and Amlogic7226/7228/8618.

媒體播放器芯片
本頁提供有關媒體播放器（高清播放機）的技術背景
高清播放機都是用SOC（系統集成芯片）設計，因而所有的硬件運轉都是包括在芯片內（視頻、網絡和接口等等）。因此，使用同樣芯片的高清播放機的性能是類似的。主要的區別來自於固件（在芯片中運行的軟件），雖然在實踐中，固件也非常相似（通常只是基於芯片廠商的SDK版本）。本頁列舉了按照廠商分類的所有的高清媒體播放機芯片和一張可以根據年代、主頻等等排序的表格（翻譯版本不能排序）。
西格瑪（下面還是寫作SIGMA，符合大家習慣）設計
第一款1080P高清媒體播放器是SIGMA 863X系列的芯片。SIGMA從2008年至今，已經設計開發了一整套高清媒體播放器芯片，是此類芯片的始祖。如之前的WDTV、A-100NMT POPCORN（爆米花，這家公司的名字有意思），都是基於300MHz的863X芯片的，而今都被更新的芯片取代。863X芯片的主要局限是：用戶界面緩慢，DTS支持受限，不夠強大。
SIGMA在2009年晚些時候發佈了SIGMA 864X和SIGMA 865X系列芯片（高清銳視N3 2010年春節前就推出了，小編不得不服），第一款使用8643機器的機器是2009年9月的POPCORN HOUR C-200（直譯是「爆米花時段C-200」），而第一款使用8655芯片的是2009年10月的WDTV Live播放器（都是美國的產品）。SIGMA 864X和865X系列是相關而且接近的芯片，而864X系列則更強大。
SIGMA 864X系列芯片時鐘主頻是667MHz，8643和8642幾乎完全一樣，除了8642支持Macrovision版本保護，可以播放有此種版權保護技術的DVD和藍光碟。864X芯片遠比865X芯片要強勁，只是產品號碼更小一些（SIGMA肯定不瞭解中國人認為編號越大越好，喜歡拿編號說事，其實編號什麼都不說明）。
SIGMA 865X時鐘主頻是500MHz，所有的865X系列芯片都是類似的，8655是全系列最強勁的，使用64位而8653使用32位（理解廠商為什麼還是用8653,64位的固件實在是不好寫，寫不好反而造成死機，降低用戶體驗，大家也要注意不要盲目跟風，咱中國的軟件還是落後），8655有6聲道DACs（數模轉化器），而8653有4個（有SPDIF就行，個人覺得這個無所謂）。可以給對這兩款芯片進行準確評價的指標也是很類似的。8654和8652支持Macrovision版權保護，讓用戶能夠觀看版權保護的DVD和藍光碟。有一點值得注意的是，所有的SIGMA都不支持RMVB播放（這點不盡然，我看到最新的資料支持RMVB V8以上的版本，不過需要廠家固件支持）。
2011年早些時候，865X和864X的芯片已經升級了，865X將升級到8656(國內有沒有廠家跟進啊)，提供千兆網絡。864X芯片將坐類似的升級到8646和8647.他們將提供800MHz，千兆網絡和3D視頻加速器（流口水啊，最早推出8643的高清銳視，千萬別讓我失望啊）。
我們也將看到對下一代SIGMA芯片的介紹。
865X系列將被8670取代，提供700MHz的主頻，低30%的發熱量和3D視頻加速功能（口水已經把地毯全打濕了）。預計將在2011年中期推出。在2011年晚些時候，我們將會看到8910推入市場，這款芯片將繼承VXP圖像加速，以提供超清晰的畫質，同時提供1080P 3D（口水滾滾而來，可是，可是，要2011年底，哎！）。這款芯片將瞄準高端用戶並且使用雙核技術，提供1200Mhz的主頻（我準備再家裡做IMAX影院了，小一點，但是我可以坐在跟前看）。
台灣瑞昱（誰能不用查字典就認識這個字，膜拜下，下面還是寫REALTEK）科技
REALTEK1283/1073芯片是在2009年中期出現的，其主頻是400MHz，REALTEK來的便宜貨在2009年如潮水一般用來（看來作者很不滿），改變了媒體播放機市場的格局（原文是要動了媒體播放機市場）。這一代的播放機主要是Xtreamer，華碩O！Play R1和ACRyan Paly!On（都是中國人的牌子，這麼喜歡用感歎號）。1073和1283是相同的芯片，有著相同的性能。但1283已經添加了錄製和數字電視的功能。REALTEK1073DA是較早的版本，不支持DTS向下混合而1073DD是罪常見的版本，可以向下混合DTS。
在2010年，據披露，無論是1073DA、1073DD還是1283都無法通過了流媒體杜比真高清和DTS-HD MA高清測試。作為對此的回應，REALTEK開始推出增強系列。1073DD+和1283+都通過了DTS-HD MA and Dolby TrueHD測試。有些播放機使用被標識為1073C，1073C+的芯片。就我們所致，這些芯片和1073DD+完全一樣。
REALTEK 1183芯片是1283(包括10/100M網絡，400MHz，DVB-T)芯片的的閹割版（老外也知道這個詞了，最近還看到有老外用HUYOU這個詞，大家都知道什麼意思吧，呵呵，香港人都不知道，這幫老外，不服不行），它在2009年5月1日通過的DIVX驗證，表明1183是和1073/1283同代芯片。查看REALTEK的發展歷程，可以知道，1183並不是所有的下一代（千萬不要被HUYOU，而市面上1283都要比1073貴，甚至貴於SIGMA 8653，千萬不要被HUYOU）。
REALTEK 的RTD 1055，1085和1185芯片相對於1073來說，是更加成功的。所有者三款芯片都在500MHz運行，所以提供了小小的性能升級，這些芯片如同上一代一樣，提供同樣的格式解析能力，只是新的芯片的發熱另更小，因而可能降低對於風扇的需求。所有的芯片都是用同樣的REALTEK 卡薩布蘭卡SDK4，即時是老的SDK，在這幾款芯片上也能提供更優的用戶體驗（觀感上來說，增加了媒體索引，增強了細節顯示———作者的話）。
REALTEK 1055 是在2010年晚期發佈的，是一款無網絡的版本，而且內存也很少（16MB閃存和128MBDDR）（譯者，不知道拿來幹嘛）。
1085和1185是1073和1283的換代產品，1185將在5月大批量出貨，而1085將在6月出貨。兩款芯片都支持千兆網絡，1085帶有512MB閃存，256MB DDR內存，而集成的閃存將允許瀏覽器運行（高清銳視N3早就可以了）。1185有1085的一切規格，並且支持DVB-T / PVR（和1283一樣）。兩款芯片都內置PCI擴展插槽模塊以便外置WIFI和其他的功能。（看看1283的離譜價格，不是很期待，另外請教了專家，為什麼各芯片廠商都不適用內置WIFI：因為WIFI會對解碼過程造成干擾，增加解碼出錯率，降低解碼效率，所以一般不予內置）。
其他製造商
AmLogic 8626H是2010年早期發佈的，作為REALTEK1073的替代品，運行在400MHz，而且其解碼能力表現至少與1073相當但卻更便宜。8626H的主要去誒按是他不支持高清音頻或者WMV/VC-1。AmLogic 8613是一款更老的用在WDTV MINI上的芯片，不支持1080P解碼。（美國貨，未必就比台灣貨強）
Telechips 8900系列（棒子貨，看看錦湖輪胎，要萬分警惕，我是寧可選台灣貨，絕不選棒子貨），主要在汽車娛樂系統中安裝，主頻為500MHz，提供大致上相當於865X新品的解碼能力。用在HDX Bone中。
Boxchip（台灣的）F10在2010年晚些時候出現，是基於SoChip SC9800（也用在一些高端移動媒體播放器中），提供7.1立體聲縮混。時鐘頻率未知，但是解碼能力相當於1073。Boxchip是一款廉價的芯片，將讓播放機更便宜（咱們中國人什麼時候能學會像蘋果一樣，讓體驗更好，而不是更便宜，只要是台灣出來的芯片，都是：更便宜、更便宜、更便宜）。
使用英特爾的播放器出現在2010年晚些時候，GOOGLE TV和BoxeeBox都是使用英特爾 CE4100。這款芯片在1.2GHz運行並且顯示支持90Mbit/s h264的視頻。在h264上與667MHz的SIGMA 864X系列相比，勉強達到同等品質。不過作為通用用途（例如上網、玩遊戲），它的性能更突出一些。（和蘋果以前的處理器類似，主頻低於英特爾，但圖形處理能力遠遠強於英特爾）。
2011年中，聯發科（MTK）將推出MTK8550，一款原本為藍光播放機設計的芯片，它支持藍光菜單和三維顯示（不是3D電影的那個3D）。因此，他的文件格式支持可能會更好，有幾家播放機已經打算使用這款芯片了。
其他的芯片如MStar D7M26L/6M68/SC9800/TCC8900 and Amlogic7226/7228/8618，我們也做了查詢，但是獲得的信息很少。
