Understanding J2ME based Open Cable Application Platform (OCAP) for Java Application Developers了解J2ME的基于开放有线电视应用平台( ocap )的Java应用开发
When Java software developers consider portable devices as platforms for their applications, they often see cell phones as the only real option.当Java的软件开发商考虑的便携式设备作为平台,为他们的申请,他们常常可以看到手机的唯一真正的选择。
Cell phone only focus is now changing.手机只有现在的重点是在发生变化。 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.与世界各地通过开放式标准数字电视平台,基于Java技术,终于成为现实,开发人员可以添加电视的,以设备列表中寻找创意的应用软件。
A national middleware platform for cable set-top boxes and digital cable-ready televisions is finally edging into the mainstream.一个国家的中间件平台,为cable机顶盒和数字有线就绪电视是最后边缘纳入主流。 It’s called OCAP, for OpenCable Applications Platform.它的所谓ocap , opencable应用平台。 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.它的基础上, Java 2平台,微型版( J2ME的) ,特别是对连接设备配置(议会)和两个相关的配置文件,该基金会的个人资料和个人的基础上的个人资料。
Two big factors are driving the heightened interest in OCAP among large and small cable operators.两大因素正在推动提高兴趣, ocap之间的大型和小型有线电视运营商。
One is the need for a national applications footprint, to help the industry to better itself against existing and new video competitors.一个是需要有一个国家申请的足迹,帮助业界更好地本身对现有的和新的视频竞争对手。 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.一个关键的区别在这一战略所需要的是使用ocap作为服务的答案为一套机顶盒是购买的有线电视运营商,然后出租给消费者。
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.另一种是预期上升,在“数字有线就绪”的消费电子设备-可能是高清晰度电视,开始-这将包括保费服务,和工作的所有经营地域。 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.四个显着的消费电子厂商-三星,松下, L G电子, D igeo公司-签署了一项计划,使他们能够合作,发展“互动式有线电视准备”设备与有线电视业。
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.我们可以预期ocap为基础的应用程式将有多达三个显着的路线,到消费性装置:租出盒,早在CE设备的基础上chila ,以及更广泛的行政长官的环境,就会出现,如果目前的谈判持双程CE设备的结果,在广泛采用对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.在短期内,所有迹象表明, ocap是为首的成数字电缆连接的设备从2006年开始,你可能可以购买一ocap功能的电视在您最喜爱的电子产品零售商在不久的将来。
What Is OCAP?什么是ocap ?
To summarize:总结:
All cable providers are aligned with an open standard - OCAP, which, when applied, will provide a national footprint for applications.所有的电缆供应商是符合开放标准-o cap,其中,应用时,将提供一个全国性的足迹申请。 Satellite providers could plausibly follow.卫星电视提供商可以振振有词地跟进。
Similarly, the majority of the digital set-top boxes leased to consumers since late 2004 contain sufficient resources to run OCAP applications.同样地,大部分的数字机顶盒租赁给消费者自2004年年底含有足够的资源来运行ocap申请。
I think the time is ripe for Java Application developers to look seriously into OCAP.我认为时机已经成熟, Java应用开发商认真研究到ocap 。 Think television.认为电视。 And especially, start thinking OCAP.特别是,开始思考ocap 。 You don’t want to be lagging behind.你不想被落在后面。
