  • [Knowledge]供應鏈波特五力模型

 資料來源: http://cdnet.stpi.org.tw/techroom/analysis/2008/pat_08_A016.htm
■ 供應鏈波特五力模型

波特五力分析(Porter 5 Force Analysis)是一個實用競爭策略分析模式。如果以策略規劃角度論,波特五力分析可當成外在環境分析(PEST)與企業本身SWOT分析中間一環。波特五力分析聚焦於與企業外部競爭最直接的五個因素,包括競爭者、上游供應商、下游買家、潛在競爭者(威脅)、替代性技術或商品(機會或威脅),並討論如何控制這五大因素,以獲取本身價值的最大化。

波特五力分析原本用於企業商品競爭優勢比較,然而任何企業內部流程與環節均可納入五力而加以考量。

【價值鏈、價值系統、產業鏈與微笑曲線】是波特五力分析的理論基礎與價值鏈架構;【波特五力分析與專利情報收集】為專利分析觀點下之競爭模型運用,供應商、顧客、競爭者與潛在競爭者為專利分析中之廠商分析,替代性技術與產品為專利分析中之技術分析;【波特五力分析的合作觀點】是將競爭者推廣到合作者或互補者,包括互補者與潛在互補者,而其理論基礎與【集競爭與合作於一身的價值網分析模型】一文討論之價值網分析接近;【業務專業矩陣與銷售波特五力模型】從如何提升客戶價值為出發,點出「客戶價值提升」其實就是銷售波特五力模型應用之一。

由上面應用討論,我們可重新用產業鏈來進行波特五力分析,我們稱為供應鏈波特五力模型。圖一為供應鏈波特五力模型架構圖,其中水平軸為產業供應鍵,若將企業本身放於中心,則上游供應商、供應商之供應商、供應商延伸、下游買家、買家之買家與買家之延伸所串起來的整體供應鏈。替代性技術群(包括本身、供應商與買家)與競爭者群(包括本身、供應商與買家),所組成另兩個機會與風險面向。圖一所有廠商與技術即組成整體供應鏈波特五力模型。

洞悉整體供應鏈波特五力模型後,對應策略可由此展開。例如要增加下游買家之價值,在不損及自身價值條件下,應盡可能替下游買家降低內外部風險與增加機會,其中買家競爭者、買家潛在競爭者、買家替代性技術與買家之買家,均為需要思考之構面。同理,若要提升供應商之價值,在不損及自身利益下,亦應盡可能提升上游供應商之機會與降低其風險,其中供應商競爭者、供應商潛在競爭者、供應商替代性技術與供應商之供應商,也是須要策略思考的構面之一。

最後,供應鏈波特五力模型是一種變動性產業競爭架構,建立是基於產業競爭現實之動態監控模型為一重點。當然,先前不同文章所討論之策略、策略規劃、策略地圖、平衡計分卡、產品組合、技術生命週期、產品命週期、價值網絡分析、價值鏈與價值系統、流程再造與創價流程等均可以與供應鏈波特五力模型充分運用。(1038字;圖1)

Southeast Asia urges cooperation over rice

Asian bank releases emergency funds for poor nations struggling with cost

updated 1:51 p.m. ET May 3, 2008

MANILA, Philippines - Southeast Asia nations meeting in Bali agreed on Saturday to cooperate over the rice market, but stopped short of concrete measures to deal with rocketing prices of the region's staple. 

The issue of food security has hijacked the weekend meeting of trade ministers of the 10-member Association of Southeast Asian Nations on the Indonesian resort island.

"The ministers affirmed that access to adequate and reliable supply of rice and stable prices are fundamental to the region's economic and social well being," said the association's statement.

To meet these ends, it said ministers recognized the need to improve productivity through technology transfers, research and development as well as making more land available for agriculture and lifting spending — both public and private.

Indonesian Trade Minister Mari Pangestu told a news conference that while the association had stopped short of "concrete actions," the group "did agree very strongly to communicate and cooperate among ourselves."

Global food crisis
The Asian Development Bank also announced emergency funding Saturday to help poor countries struggling with soaring food prices and warned these could keep rising and stifle economic growth in the region.

"The cheap food era may be over," the bank's President Haruhiko Kuroda told a news conference in Madrid, where the band held its annual meeting.

The new aid will come in the form of soft loans for the governments of countries hardest hit by the global food crisis, such as Bangladesh.

Kuroda declined to give an overall figure for this expenditure, saying it would depend on requests governments make. He said the amount would be "sizable, but not enormous."

The African Development Bank offered $1 billion more in food aid and urged grain-exporting countries not to curb shipments.

Countries including India, Vietnam, Indonesia and Brazil have restricted food exports in a bid to secure domestic supplies and limit inflation. Guinea on Saturday announced it was setting up an emergency food stock, especially for rice.

Former U.N. chief Kofi Annan said on Friday that farmers in Africa could double food output in five to 10 years if rich countries partner them in a "Green Revolution" for a long-term solution to the continent's food crisis,

Annan, who led a meeting of agriculture experts in Salzburg, said in a teleconference call that major funding was required to offset the impact on the world's poorest continent of the sharp price hikes for essential food and fuel.

Humanitarian aid could only be the first step of a longer-term strategy which should seek "to enable African farmers to dramatically increase their output so that Africa can feed itself and not be dependent on food aid."

'Massive violation' of human rights
The World Food Program has described soaring food prices as a "silent tsunami" that threatens to plunge more than 100 million people into poverty.

The new U.N. food envoy on Friday sought a special meeting of the U.N. Human Rights Council this month to address a global food crisis he said was a "massive violation" of human rights.

Olivier De Schutter said he wanted the Geneva-based Human Rights Council to hold a special session around May 22 or 23 to complement efforts by other international agencies to tackle the crisis and to establish it as a human rights issue.

"If we had 100 million persons arrested in a dictatorial regime, if we had 100 million persons beaten up by police, of course we'd be marching in the streets and we'd be convening special sessions," De Schutter said at a news conference.

Protests, strikes and riots have erupted in developing countries around the world after dramatic rises in the prices of wheat, rice, corn, oils and other essential foods that have made it difficult for the poor to make ends meet.

President Bush proposed this week $770 million in new U.S. food aid to stave off the crisis, pledging Washington would take the lead in combating global hunger.

Bush said on Friday food prices have been rising as a result of soaring energy prices but the use of corn-based ethanol is not the main driver behind rising prices at the supermarket.

Southeast Asian trade ministers repeated in their statement a commitment to conclude the long-delayed Doha round of global trade negotiations by the end of the year.

The food crisis should be a "big jolt" to concluding the global trade negotiations, said Australian Trade Minister Simon Crean, who was also attending the Bali meeting.

He said good progress had been made in the past few weeks but a possible May 19 date for a potentially key Geneva meeting of World Trade Organization ministers was looking unlikely.

"We're hopeful that a date very soon after that is."

The Doha negotiations were launched in 2001 to lower barriers to trade to give the world economy a lift and help the poorest countries to fight poverty by exporting more.

But negotiators say the talks risk more years of delay or outright collapse if there is not a breakthrough soon.

  • [轉載China's At-Risk Factories

 resource from: http://www.time.com/time/magazine/article/0,9171,1731898-1,00.html
China's near miraculous economic rise has been built on the smarts of men like Cheng Wei-lun and the sweat of the 800 workers he employs as chief executive of the Tianji Wooden Products Co. Based in Guangdong province in southern China, the company, which exports $10 million worth of toys and children's furniture annually, is like thousands of other small manufacturers that help form the backbone of the country's formidable export-manufacturing machine. But that frame is showing cracks, and all the brains and brawn in the world might not be enough to rescue Tianji Wooden Products. Cheng's costs have gone up 30% in each of the past two years, but competition is so fierce that he can't raise prices. "Our profits are gone," Cheng says. "If something doesn't change in the next few months, I will have to shut the factory."
Something is about to change--but almost certainly for the worse. Higher labor costs, a strengthening Chinese currency and soaring raw-materials prices are bad enough. Now a slowdown in global growth and a likely full-blown recession in the U.S. are about to stress-test China's manufacturing sector like never before--and could result in the shuttering of thousands of factories and cost hundreds of thousands of workers their jobs. Makers of low-end goods are already suffering. The Guangdong city of Huidong was home to 3,000 shoe factories at the beginning of 2007, but as many as 500 of them have closed over the past 15 months, says Li Peng, secretary of the Asia Footwear Association in Hong Kong. One-sixth of 44,200 textile firms tracked by the China National Textile and Apparel Council lost money last year, and two-thirds are just breaking even. "Manufacturers' profits are so low that when they hit the slightest snag, they have to close," says Li.China's sweatshops have every reason to sweat. America buys about 19% of China's $90 billion in monthly exports. As the U.S. economy began to falter in late 2007, China's torrid export growth rate--for the past several years running at an annual rate of 20% or higher--was showing unmistakable signs of a slowdown. In February it plummeted to just 6.5%, compared with nearly 20% growth expected by economists. Exporters suffered major disruptions from power outages and transportation delays caused by that month's heavy snowstorms, but sluggish U.S. demand was also to blame. The value of U.S.-bound goods showed a rare year-over-year decline that month of 5.3%.Although China is the world's second largest exporter, the country is not as dependent on overseas trade as some. Exports accounted for 36.8% of China's GDP in 2006, compared with 43.2% in South Korea. But China may be unusually vulnerable to weaker international demand because the country has in recent years built too many new factories. With investment capital readily available and China's economy roaring ahead at double-digit growth rates, heavy industry expanded massively. The value of China's steel exports, for example, jumped tenfold from 2003 to 2007, from $5 billion to $50 billion.China's central government recognized early on that an investment bubble was probably forming. In 2004, for both economic and environmental reasons, authorities in Beijing began pressuring provincial and local officials to curb spending on aluminum, steel and cement factories; state-owned banks were periodically told to stop lending for industrial projects. But local officials often ignored the stop signs. More factories meant more jobs and more growth, which made them look good in the eyes of their political superiors. Not only that, but local officials, who can seize land and issue permits for new projects, were often silent partners in new manufacturing ventures. Too many factories were built as a result.This overabundance of production capacity means China's export machine is like a race car with no brakes. As long as the road remains smooth and straight, the car roars ahead. But throw in some potholes and a tight turn, and the wheels come off. Factories have been able to increase output in recent years because the global economy has been on a tear. The 2004-07 period saw the second strongest bout of global growth on record--which translated into strong demand for cheap Chinese-made products. But this era may be ending. Most economists are forecasting a significant slowdown in worldwide GDP growth in 2008. This slowdown, predicts Lehman Brothers economist Sun Ming-chun, will prove to be the "unmasking of [manufacturing] overcapacity in China." Says Li of the Asia Footwear Association: "The cake is only so big, and when you have too many people trying to eat it, you will definitely have some go hungry."Some are already starving. China's competitive advantage has been its armies of cheap workers, but that edge is getting dull. Labor costs have increased 50% in the past four years across southeastern provinces--an area of China sometimes called the "workshop of the world"--and a new labor law passed by Beijing will only add to the burden. Jonathan Anderson, an economist at UBS in Hong Kong, says factory owners in southern China believe the new law will drive labor costs an additional 10% to 25% higher. Among other provisions, the new law entitles laid-off workers to one month of severance pay for every year of employment. "In a case where an export market is going down, if you want to reduce your number of workers, then you face a lot of problems," says Stanley Lau, vice chairman of the Federation of Hong Kong Industries. To lay off people, "you need to pay a huge amount in compensation." Nor is there any relief from surging raw-materials costs. And slowly but surely, the renminbi, China's currency, continues to strengthen--it's now 12% higher against the U.S. dollar than it was 18 months ago--making China's exports more expensive worldwide.A major retrenchment could have serious consequences for China's economy and society. The specter of legions of laid-off migrant workers roaming the streets in search of jobs is bound to keep Beijing's economic policymakers--who fear the political consequences of widespread social unrest--up at night. Sun, the Lehman Brothers economist, says that as manufacturers are pushed to the brink, China's stock markets could see sharp declines. Given that many large, listed Chinese companies pad their profits by investing in stocks themselves, "a big correction could bring [corporate earnings] even lower, and a vicious cycle could result," says Sun.

世界經濟展望報告:美危機讓全球經濟陷衰退法新社更新日期:2008/04/10 01:00

(法新社華盛頓八日電) 國際貨幣基金今天說,美國房市重挫影響仍在擴散,由於美國似乎無法避免陷入衰退,全球經濟前景越來越嚴峻。該機構預估台灣今年的經濟成長為百分之四。

國際貨幣基金今天發布半年度「世界經濟展望」報告,源於美國的危機持續展現,今年全球經濟成長預料將減緩為百分之三點七。

報告指出,今天公布的經濟成長預測,比世界經濟展望一月份更新報告中提出的數據低了百分之零點五。

由於房價進一步下滑,加上信用條件仍相當艱困,全球最大經濟體美國的經濟可能「微幅衰退」,在明年大多數時間將告停滯。

對全球經濟而言,今年與明年經濟成長率不到百分之三的機率達二成五,國際貨幣基金指出,這樣等同於全球經濟陷入衰退。

國際貨幣基金說,美國是經濟動盪的震央,儘管政府投入數百億美元推動振興經濟方案,美國今年經濟仍僅微幅成長百分之零點五。

由於金融機構整理資產負債表,美國經濟預料明年將「微幅」復甦,成長率回升為百分之零點六。

國際貨幣基金說,在其他先進國家中,由於金融市場緊繃及若干國家房市走跌,西歐成長率將減緩至「遠不及」應有的水準。

十五國歐元區成長預估今年將減緩為百分之一點四,明年為百分之一點二,相較於一月更新報告中的數據分別下修百分之零點二與百分之零點七。

全球第二大經濟體日本預估今年將減為百分之一點四,明年略升為百分之一點五。

國際貨幣基金說,相較之下,新興開發中國家面對市場壓力顯然較具適應彈性,因為它們逐步整合進全球經濟中,加上商品價格飆漲,均支撐這些國家的經濟。

這些國家整體成長今年將減為百分之六點七,相較於先前的預測下修了百分之二點二,但仍相當強勁,而明年將減為百分之六點六。

中國將繼續引領全球成長,今年成長率為百分之九點三,明年百分之九點五。

新興工業化經濟體南韓、台灣、香港與新加坡,預估成長率為百分之四,低於去年的百分之五點六。

  • [轉載]哲學001-中國 老子

資料來源: http://www.legacy1.net/lao_tze.html
Lao Tze
西出函谷、化胡為佛
 Very little is known about Lao Tze. So little that even his surname is clouded in uncertainties. However, it is generally accepted that his name was Li Er (李耳) or Lao Tan (老聃), and was born in the state of Chu (楚國) during the Zhou dynasty (周朝), but the date of his birth is another mystery. Another accepted fact is that he was a keeper of archive (守藏室之史) in the Zhou court. It was while working in this capacity that Confucius (孔子) came and consulted him on matters of ceremonies and rites. Based upon this encounter it is assumed that he was older than Confucius.

It is unclear when he left this post. Legend has it that after leaving he decided to travel westward riding an oxen. At this time a purple cloud started to hover over him. Thus this journey is generally referred to as the Purple Cloud from the East (紫氣東來). One day he came to China's westmost outpost (函谷關). The guardian of this outpost had heard of Lao Tze, his learning  and his westward journey. He specially ordered his underlings to keep their eyes open for Lao Tze and when spotted should reported to him immediately. Upon meeting Lao Tze, he accorded Lao Tze the respects of a student to a teacher and asked Lao Tze to leave some of his wisdom in the form of writing behind. At this point Lao Tze wrote a 5,000 word essay titled Tao Te Ching (道德經). After he finished the essay, Lao Tze continued his westward journey and not to be heard from again.

Here is a brief listing of some of the ideas and concepts in the Tao Te Ching:

  • Tao (道) is the invisible, intangible, and indescribable force which created the universe.
  • Ideas and matters exist in pairs and are relative in that the pairs are always opposite yet depending on the other for its own existence. An example is good and evil. We know good when we encounter it only because we have known or encountered evil.
  • Strength of the weak or soft is greater than the forceful or hard because the hard will break while the soft will bend and rebound.
  • Advocated a return to the simple life of bygone days when people were self-sufficient and uneducated.
  • For government he advocated sparsely populated small states where people have very little contact with each other.
  • Most important of all is the concept which can loosely translated as let it be (無為).

The philosophy as outlined in Tao Te Ching became popular during the early part of the Han Dynasty (漢朝). It is credited with calming the country and settling the population after the turmoil of the Warring States (戰國), the harsh Qin Dynasty (秦朝) and the ensuing civil war (楚漢相爭). From this base Wu Emperor (漢武帝) was able to launch his successful campaigns of driving the Northern nomads, Xiongnus (匈奴), far into the desert.

Hundreds of years later, the Taoists (道教) while battling Buddhism (佛教) for followers adapted Tao Te Ching as their religion's dogma. In turn they honoured Lao Tze as the founder of their religion. However, honours didn't really started to pour in until the Tang Dynasty (唐朝).

Keep in mind that since the latter part of the Han Dynasty, bloodline and ranked clans (門第望族) were of utmost important. At one point clan membership was the only requirement for high ranking positions in government (上品無寒門,下品無望族). Capability and learning played no part whatsoever. Yes, this is a caste system. Its meridian was during the North-south period (南北朝). The two most powerful clans were Wang (王) and Xie (謝). Stories had it that during the early Tang dynasty the emperor had trouble finding a spouse for one his daughters as the royal family was ranked six on list of desired matches. <> Then it is understandable for the royal family of the Tang Dynasty who was very conscientious of its somewhat mixed bloodline to seek direct linkage to a historical Han figure. That figure happened to be Lao Tze. Taoism in turn became the national religion during the Tang Dynasty.

It all started in May 620AD (武德三年) when Ji Shan (吉善) of Jinzhou (晉州) walking along Sheep Horn Mountain (羊角山) met a very dignify-looking old gentleman on a white horse with red mane.

The elderly man said, "Go and inform the Tang Emperor that I am his ancestor. At the end of the year there will be peace and his descendants will be on the throne for a thousand years."

Lee Yun was amazed by this and decided to build a temple where the alleged meeting took place. This was the first step in solidifying the link between the Tang Emperor and Lao Tze. Later a royal edict officially ranked Taoism ahead of all religions.

  • [轉載]數位家庭時代的產業分工與進化

 數位家庭時代的產業分工與進化
(DigiTimes.com企劃)2005/06/01

家用消費性電子的數位進化論
 在有關消費性電子未來發展的諸多討論中,最常出現的主題就是科技統合(convergence),探討如何匯集傳統PC、行動運算和消費性電子領域,建立一個新應用與新消費者裝置的大熔爐,淡化傳統領域的分界線。我們必須了解,一如其他任何進化歷程的特性,「統合」是一種程序,在這個過程中新的應用和裝置將在市場上陸續出現,它們或許會在市場上成長並且進一步的演化,亦或者被證明無法繼續生存而消失於市場。
 對於消費者、服務供應商和設備製造商而言,此種數位進化論(Digital Darwinism)提供了一股源源不竭的動力,激發人們推出各種超乎人們以往所想像的新應用、使用方法和商機。然而,廣泛多樣化的選擇性,以及消費者對於其中許多選擇的不信任感,卻可能讓價值鏈中的諸多廠商感到不確定或懷疑。因此,我們需要仰賴標準和互通性架構,將科技統合導向正確的方向。
 數位家庭設備的互通性
 「統合」代表的可能是消費者透過網路購買和下載到電腦的版權歌曲可以轉到可攜式音樂播放器中;也可以代表用行動電話所拍攝的相片可以在電視上顯示或用電腦的印表機來輸出;也可能代表了用數位個人錄影機(PVR)收錄的電視節目可以在晚上自動下載到行動電話上,以便於隔日早上通勤時觀看。許許多多新的使用方式將會出現,讓消費者可以在行動電話、可攜式裝置、家用消費性電子設備和個人電腦之間傳輸內容資訊。內容的格式不再局限於單一的裝置,而應該被廣泛的支援。
 過去10年間開發出許多不同的數位音訊、視訊和圖片壓縮機制,使用於各種不同的應用和裝置中。有些編解碼器是以開放標準為基礎,而有些則屬於專屬格式。通常,一種編解碼器能支援多種選擇和工具,可為特定的應用或裝置開發較適用的媒體。然而,單單以編解碼格式的數量和每一格式提供的選擇而言,我們幾乎不可能製造出一種支援所有格式的萬能裝置。再者,越來越多的數位財產權管理(Digital Right Management,DRM)方案,更增添了複雜的程度。著名的電腦科學作者Andrew Tanenbaum 雖曾說過:「存在多種標準的好處就是可有很多標準供選擇」,然而對消費者而言,太多種類的格式卻會讓人無所適從。
 為了確保最基本的互通性並消除消費者心中的疑慮,必須以最基本的設備需求為影音和圖片內容的解碼定義出基本的規範綱要。1990年代中期,數位視訊廣播(Digital Video Broadcast)聯盟定義了MPEG2規範建置方針(之後演進成為ETR 154),針對廣播業者所可能會使用到數位電視接收器的功能,如MPEG2視訊解碼、音訊解碼、解多工(demultiplexing)工具與選項等,定義了一套最低限的規範子集合。同樣的,數位家庭也需要一組最低限的規範清單,包括各種裝置所需的解碼器、編碼器、DRM解決方案和連接工具。由各個消費性電子、個人電腦和行動裝置產業的領導廠商所組成的數位家庭網路聯盟(Digital Living Network Alliance ; www.dlna.org/home),就是為了發展這樣的裝置規範,以及建立消費者信任的認證機制。一些如AAC (MPEG-4 Advanced Audio Coding)、AVC (MPEG-4 Advanced Video Coding,也稱為H.264)和OMA-DRM (Digital Rights Management Solution;原先是針對行動電話設計的,但同樣適用於消費性電子和個人電腦的應用)等格式,似乎都是數位家庭裝置規範應涵蓋的優良候選者。
 消費性電子產業的分工
 過去,消費性電子的OEM廠商們為消費性電子產品提供最大部分的附加價值。消費性電子的OEM負責最大多數的研發工作,而僅向供應商採購最基本的元件。然而在這25年間,由於半導體的整合,使得大部分的附加價值從消費性電子的OEM轉移到半導體廠商。當消費性電子產品開始使用越來越多的軟體時,半導體廠商也開始承擔起大部分的軟體開發成本。

 然而,隨著消費性電子產品中使用軟體內容數量的爆炸性成長,但是軟體開發者的平均生產力並沒有達到同等幅度的成長,我們必須找出能夠支持相關軟體投資的創造性解決方案。
 一如消費性電子的OEM廠商,半導體廠商通常缺乏可以支持內部自行開發符合市場所需的完整功能與應用軟體的經濟規模。再者,這些軟體對於半導體公司而言大多是不具區別性(non-differentiating)的,所以目前的半導體產業大體上是在從事大規模的重複軟體開發工作;許多半導體公司把創新的能力浪費在重新發明同樣的「非區別性產品」,並因此減緩了半導體廠商的創新速度。所謂「非區別性」軟體包括互動式電視中介軟體(MHP、MHEG、OCAP等)、網路協定堆疊(TCP/IP)、互連軟體(UPnP)及其他中介應用(PVR stacks、EPG、Picture Browsers、Music Jukebox) 等。
 不論對消費性電子產品OEM或半導體廠商而言,專注於本身的專長領域才是最符合利益的,凡是不屬於本身專業的部份都應該交由專門人員負責。獨立軟體商(ISV)可以藉由向廣泛的消費性電子產品廠商提供支援各種半導體平台的特殊軟體模組,以建立經濟規模並維持其利潤。消費性電子產品ODM和系統整合業者可以負責這些ISV軟體在各種平台上的導入和測試,以及提供符合個別消費性電子OEM需求的客製化產品。因此,消費性電子OEM和半導體產業需要延伸他們的產業生態系統,將ISV、系統整合業者和ODM廠商涵括進來。

▲圖說:消費性電子價值板塊 建立共用的設備架構

 為了建立一個有生命力的產業生態系統,讓每個人扮演好自己的專業角色並且能夠建立區別性和產生可長可久的利潤,消費性電子裝置將需要統合到共同的架構,以在產品內建置共同的硬體和軟體介面。半導體解決方案應該被架構成一個真正的平台,支援一組定義完整、穩定且低障礙的低階平台介面,以簡化ISV的軟體開發。一般而言,這些平台介面應包括作業系統,以及一套應用程式介面(Application Programmers Interface; API)以處理音訊、視訊、串流等作業系統不支援處理的部分。
 綜觀目前使用中的作業系統,Linux最有機會成為消費性電子產業的實質標準。然而,要實現這個目標仍有賴一些發展配合,如改善穩定性、記憶體針腳空間、啟動時間和其他一些符合消費者對於消費性電子產品所期待的屬性等。消費性電子Linux 聯盟(The CE Linux Forum, www.celinuxforum.org )正是基於這個目的而在2003年成立,並已在上述的領域有顯著的進展。
 音訊/視訊/串流API的階層必須夠低,才能為軟體廠商提供最大的彈性,同時也必須高到足以達到硬體獨立性
(hardware-independent)。如果我們能在無排他性的(non-discriminatory)原則之下將API發展成一個開放的業界標準,就能夠建立強大的動能以支撐業界經濟規模和系統的穩定。
 UHAPI 聯盟於2004年11月成立,其目的是要建立通用家庭應用程式介面(Universal Home API; UHAPI;www.uhapi.org)。2005年1月,第一版的UHAPI 1.0規範推出,初期以類比和數位電視做為規範對象。UHAPI進一步的延伸規範如對錄音/影應用的規範還正在發展中。UHAPI聯盟的會員包括飛利浦、三星、惠普(HP)、Access、中國數位電視產業聯盟(DTVIA)、nVidia等。
 UHAPI將為中介軟體和應用軟體開發者降低影音功能程式設計的複雜性,例如訊號調諧、解多工、媒體解碼和視訊混合等。軟體開發者所面對的將是一個完全獨立於硬體之外的影音控制介面,將可以自由地專注在為各種終端產品做中介軟體與應用軟體的創新開發,而不再需要擔心硬體或中介軟體的複雜性問題。

 UHAPI將建置在一個量身定製的影音軟體層(A/V software layer)上,以確保硬體效能的最佳化,並發揮每一個相容SoC平台的架構與功能優勢。
 誠如其名,API能為應用開發者提供非常大的幫助。現在的開發商必須自行編寫連接影音元件而通常極為複雜的程式。透過API功能,這些工作可真正被精簡成只需要一個簡單的函式呼叫(function call)。因此,開發者對於應用程式碼的編寫將更具信心,將更可以確定這些程式可以在DVD錄影機、電視、媒體配接器及其他任何裝置上執行,而無需擔心硬體或中介軟體複雜性的問題。例如,針對電視所開發的一個電子節目表(Electronic Programming Guide; EPG)便可以直接「丟進」一台DVD裝置上來使用。
 結語以上這些業界聯盟計畫的關鍵目標就是要促進科技統合以及持續不斷地的進行應用與裝置的創新開發。標準與互通性的架構是建立市場動能的必要條件。然而,我們不應忘記的是,並非只有應用和裝置需要發展與進化,相關的標準與架構同樣不能停下發展的腳步。它們不斷的更新發展,我們的架構和裝置拓墣也應配合潮流的變化。美國哲學家Alfred Whitehead為此下了一個註解:「進步的藝術是要在變化中維持秩序並在秩序中尋求變化」。(本文由飛利浦半導體提供/作者Paul de Bot現擔任該公司消費事業群業務發展副總裁)
