Transcoding Technology
Overview
Transcoding Technology to make Web pages available on handheld and other devices. One can also format XML-based information for HTML browsers and other uses or convert data to voice output. If used with WebSphere Translation Server, transcoding technology can translate information into the user's preferred language.
By providing a single dissemination point for multiple renderings of information, transcoding technology eliminates the expense of re-authoring or porting data or applications for multiple networks and devices. By transforming content based on what the requesting device can handle. Web content can be transformed differently for different devices. Transcoding Technology supports existing applications and data without requiring that a redesign of corporate systems for the different standards found in each device.
Data transformations are done on the network side of a connection, rather than in the device browser.
Scenarios
These scenarios illustrate some of the ways Transcoding Technology can be used in the organization.
- Web application output tailored for remote workers
- Your technical consultants use monochrome handheld devices to access a Web-based information repository. The Web pages contain full-color graphics, text descriptions, and complex forms. Configure a Transcoding Technology server to perform the following operations before transmitting Web pages to these users:
- Format tables to lists
- Convert images to text links
- Convert images to grayscale and reduce their resolution
- The result is that the forms are intact but sized for the screen. The tech consultants can access information faster and with fewer problems in displaying the relevant data.
- Host data transformed in secure environment
- A host transaction system generates financial data for a secure Web server. Your market finance group needs access to this data from their office desktops as well as from their mobile devices. Transcoding Technology transcodes the output of Web applications to the proper formats, and the Web server encrypts and returns the data.
- Multi-version support for devices
- Transcoding Technology transforms content for a device that does not support JavaScript by removing the JavaScript from any document that contains it. A vendor upgrades the device to support JavaScript. You obtain a new device preference profile from the vendor. You configure WebSphere Everyplace Access to recognize the new device and indicate in Transcoding Technology's matching preferences the upgraded capability. Any user who accesses WebSphere Everyplace Access with the new device receives content containing JavaScript. Users with back-level devices continue to get content without JavaScript.
- Deck fragmentation for smaller devices
- Your employees use handheld devices with screens that display small amounts of data received using the WML or Compact HTML formats. Transcoding Technology converts the original HTML to the appropriate markup language and then breaks the information into fragments of the size the phone can store. This means that application developers do not have to write different versions to support phones with different capacities.
