Understanding J2ME based Open Cable Application Platform (OCAP) for Java Application Developers了解J2ME的基於開放有線電視應用平台( ocap )的Java應用開發
When Java software developers consider portable devices as platforms for their applications, they often see cell phones as the only real option.當Java的軟件開發商考慮的便攜式設備作為平台,為他們的申請,他們常常可以看到手機的唯一真正的選擇。
Cell phone only focus is now changing.手機只有現在的重點是在發生變化。 With worldwide adoption of open-standard digital television platforms based on Java technology finally becoming a reality, developers can add Television’s to the list of devices looking for creative software applications.與世界各地通過開放式標準數字電視平台,基於Java技術,終於成為現實,開發人員可以添加電視的,以設備列表中尋找創意的應用軟件。
A national middleware platform for cable set-top boxes and digital cable-ready televisions is finally edging into the mainstream.一個國家的中間件平台,為cable機頂盒和數字有線就緒電視是最後邊緣納入主流。 It’s called OCAP, for OpenCable Applications Platform.它的所謂ocap , opencable應用平台。 It’s based on the Java 2 Platform, Micro Edition (J2ME), and specifically on the Connected Device Configuration (CDC) and two related profiles, the Foundation Profile and the Personal Basis Profile.它的基礎上, Java 2平台,微型版( J2ME的) ,特別是對連接設備配置(議會)和兩個相關的配置文件,該基金會的個人資料和個人的基礎上的個人資料。
Two big factors are driving the heightened interest in OCAP among large and small cable operators.兩大因素正在推動提高興趣, ocap之間的大型和小型有線電視運營商。
One is the need for a national applications footprint, to help the industry to better itself against existing and new video competitors.一個是需要有一個國家申請的足跡,幫助業界更好地本身對現有的和新的視頻競爭對手。 A key distinction in this strategic need is the use of OCAP as a services answer for the set-top boxes that are purchased by cable operators, then leased to consumers.一個關鍵的區別在這一戰略所需要的是使用ocap作為服務的答案為一套機頂盒是購買的有線電視運營商,然後出租給消費者。
The other is the anticipated rise in “digital cable-ready” consumer electronics devices - probably high-definition TVs, to start - that will include premium services, and work across all operator geographies.另一種是預期上升,在“數字有線就緒”的消費電子設備-可能是高清晰度電視,開始-這將包括保費服務,和工作的所有經營地域。 Four notable consumer electronics companies - Samsung, Panasonic, LG, and Digeo - have signed a plan that enables them to co-develop “interactive cable-ready” devices with the cable industry.四個顯著的消費電子廠商-三星,松下, L G電子, D igeo公司-簽署了一項計劃,使他們能夠合作,發展“互動式有線電視準備”設備與有線電視業。
We can expect OCAP-based applications will have as many as three significant routes into consumer devices: leased boxes, early CE devices based on CHILA, and the wider CE environment that will appear if current negotiations about two-way CE devices result in widespread adoption of OCAP.我們可以預期ocap為基礎的應用程式將有多達三個顯著的路線,到消費性裝置:租出盒,早在CE設備的基礎上chila ,以及更廣泛的行政長官的環境,就會出現,如果目前的談判持雙程CE設備的結果,在廣泛採用對ocap 。 In short, all signs indicate that OCAP is headed into digital-cable-connected devices starting in 2006, and you may well be able to purchase an OCAP-enabled television at your favorite electronics retailer in the near future.在短期內,所有跡象表明, ocap是為首的成數字電纜連接的設備從2006年開始,你可能可以購買一ocap功能的電視在您最喜愛的電子產品零售商在不久的將來。
What Is OCAP?什麼是ocap ?
To summarize:總結:
All cable providers are aligned with an open standard - OCAP, which, when applied, will provide a national footprint for applications.所有的電纜供應商是符合開放標準-o cap,其中,應用時,將提供一個全國性的足跡申請。 Satellite providers could plausibly follow.衛星電視提供商可以振振有詞地跟進。
Similarly, the majority of the digital set-top boxes leased to consumers since late 2004 contain sufficient resources to run OCAP applications.同樣地,大部分的數字機頂盒租賃給消費者自2004年年底含有足夠的資源來運行ocap申請。
I think the time is ripe for Java Application developers to look seriously into OCAP.我認為時機已經成熟, Java應用開發商認真研究到ocap 。 Think television.認為電視。 And especially, start thinking OCAP.特別是,開始思考ocap 。 You don’t want to be lagging behind.你不想被落在後面。
