EBIF
JA What is EBIF?
<!--
EBIF - "Etv Binary Interchange Format". An Enhanced TV (ETV) application format that agents on legacy, resource constrained devices use to recognize that there is interactive content on the channel. EBIF defines the complete end-to-end system including how bits go on the wire, which authoring tools spit their bits out in EBIF, and which end user devices interpret or decode EBIF bits. Both content and service providers can pick whatever EBIF-spitting tools they want. Service providers additionally must select which ETV end user device software they buy. -->
OEDN presents three downloadable EBIF tutorials courtesy of Luxoft
We're grateful to Luxoft (luxoft.com), an OCAP/EBIF developer based in Russia, for allowing us to repost several tutorials (including code), with links to download the source code for each.
These tutorials assume a basic knowledge of EBIF technology and all sample applications were developed and tested using TVWorks XDK, Eclipse IDE and Tomcat Application Server.
Dynamic Content in EBIF Applications Using Two-Way Communication
Building a simple EBIF application featuring dynamic content using two-way communication.

An extension of the 'Dynamic Content' tutorial, create a complete EBIF application using two-way communication
Insert Characters Into Text Fields Using the Remote Control in EBIF Application
When using the textinput widget, you can easily send numeric characters by pressing the digits on the remote control, but to send alpha-characters to the user interface, an additional programming effort is required - this tutorial presents a simple solution to this issue

It's Working: NYU's Twitter ETV Test Application
Introducing the Twitter proof-of-concept app, an EBIF app created by Shawn Van Every of NYU. With EnableTV's help to get this app running and accessible via SlingPlayer, this the the first example of and end-to-end test that OEDN has facilitated.
More about this application:
This is a bound application (tied to an MPEG-2 stream) that puts up a button that says "Get Last Tweet". If you push the "Select" button on the remote, a Java CGI application which is used for EBIF 2-Way Packaging triggers a PHP script, which returns XML for packaging. The PHP script uses the Twitter API and pulls up the latest message to Twitter. When the EBIF application receives a response from the Java CGI app, it displays that message over the top of the video.
2010 - The year of EBIF
As Verizon's Widget Bazaar vision rolls out, excitement for EBIF applications is spreading with increased urgency. FiOS's new widgets, including Facebook and Twitter on TV, are examples of these micro-apps that can spin up in short order.
Leslie Ellis, technology analyst for Multichannel News, breaks EBIF all the way down to “ee-biff” in today's feature. She cautions, "if consumers are exposed only to EBIF triggers that lead exclusively to ads, they could easily 'learn,' incorrectly, that clickable things on the TV screen are ads, so why bother."

Testing an EBIF Application 101
Right now (as of September 2009) the testing process for EBIF applications is confusing at best - so here's some insight on the current state of testing an EBIF application.
While EBIF is a widely accepted standard for developing ITV applications, there is not a standard method for getting an application tested and deployed across millions of digital set-top boxes within the US cable MSOs (multiple system operators). Application developers will need to discover the current certification method on an MSO by MSO basis prior to deployment.
