What is Transcoding Technology
About this documentation
This section discusses the Transcoding Technology architecture, how to utilize Transcoding Technology facilities like preference aggregation, working with stylesheets and annotators, using XML configuration, using special transcoding plugins and data transformation.
What is Transcoding Technology
Transcoding Technology enables us to make Web-based information available to users of handheld and other pervasive devices economically and efficiently. Transcoding Technology modifies content presented to users based on the information associated with the request, such as device constraints and organizational policies. This transformation of information from one form to another is the central idea behind transcoding, a technology particularly suited to bridging the gaps between the variety of data formats encountered on the Web and the devices comprising them.
Transcoding Technology uses specialized programs called transcoding plugins to perform different conversions, such as from HTML for a browser, to WML for a Web-enabled cell phone. Transcoding Technology 's architecture provides a pluggable framework for adding new device and content type transformations, by developing new transcoding plugins.
Enable and disable Transcoding Technology
This is no longer enabled by default with IBM WebSphere Portal. To enable Transcoding Technology run the following command from the portal_server_root/config directory:
UNIX:
./WPSconfig.sh configure-transcoding
Windows:
WPSconfig.bat configure-transcoding
- i5/OS:
From the UserData directory path portal_server_root/config:
WPSconfig.sh -profileName profile_root configure-transcoding
...where profile_root is the name of the IBM WAS profile where WebSphere Portal is installed; for example, wp_profile.
- After running the configure-transcoding task, stop and restart the portal server for the changes to take effect.
To disable Transcoding Technology run the following command from the portal_server_root/config directory:
- UNIX:
./WPSconfig.sh
remove-transcoding
Windows:
WPSconfig.bat remove-transcoding
- i5/OS:
From the UserData directory path portal_server_root/config:
WPSconfig.sh -profileName profile_root remove-transcoding...where profile_root is the name of the WebSphere Application Server profile where WebSphere Portal is installed; for example, wp_profile.
