NetFront™ Transcoder


A next-generation web-to-mobile transcoding server solution that leverages the NetFront Browser engine, the World's Browsing Standard

NetFront™ Transcoder brings the power of the Internet to mobile devices. Web sites are generally designed for personal computers, making the sites unusable by many mobile devices. NetFront Transcoder is a next generation server solution using the NetFront™ Browser engine to pre-render and reformat content, thereby, making that content usable by mobile devices. NetFront Transcoder exemplifies ACCESS' commitment to bring the Internet to mobile devices. It is for this reason and others, why the NetFront Browser is the most popular choice for manufacturers and operators. In fact, NetFront™ products, including the NetFront Browser as an embedded Internet browser, have shipped in over 590 million devices (as of May 31, 2008) throughout the world, including mobile phones, digital TVs, set-top boxes, mobile handhelds, game consoles, automobile navigation systems and many other types of products.

NetFront Transcoder includes automatic conversion functions as well as editing tools that enable website producers to easily repurpose their sites for mobile devices.



The Advantage | NetFront Transcoder

Automatic Conversion
NetFront Transcoder automatically converts standard web pages for display on mobile devices. It uses the NetFront Browser engine to parse web page content blocks and analyze their structure to determine the optimum layout for display on mobile devices. NetFront Transcoder can interpret JavaScript™, CSS and Flash, making it possible to convert rich web content in real time. In addition, NetFront Transcoder can recognize the screen size, supported formats, and memory capacity of individual devices and can thus optimize content for any type of mobile device.


Easy-to-Use Editing Tools
After an automatic conversion, NetFront Transcoder's visual editing tools make it easy to edit the mobile content generated, if the editor so desires. A variety of editing operations can be carried out with drag-and-drop simplicity, including the reconfiguration of parsed content blocks and the replacement of text with images to improve user interaction. NetFront Transcoder's editing tools are so intuitive that even a non-programmer can use them.


Linking with External Systems
With an extensive set of functionalities, NetFront Transcoder's editing tools also make it easy to link site content to external systems such as advertisement services.

Supports a Range of Internet Sites
NetFront Transcoder formats and converts web content designed for a personal computer into a format more appropriate for a mobile device, including script processing and managing sessions and cookies. NetFront Transcoder allows you to access Internet search sites, check web mail, access shopping sites, read weblogs, etc. In other words, you can access the Internet sites you usually use with your personal computer from your mobile device.

*Depending upon the capabilities of your mobile device, some sites may not display completely or some services may not be available.

Flexible System Configuration
NetFront Transcoder implements a scalable and flexible architecture, which can be configured to address the sizing needs for the web sites.

  • High Load Operation
    As shown in the figure below, it is possible to internetwork the load balancer and content conversion server to provide increased scalability. In the case of high load operations, the processing of HTTP requests can be distributed across several content conversion server using a load balancer. Content conversion servers can be expanded in parallel to provide greater flexibility as traffic load increases.
  • Redundancy
    As shown in the figure below, NetFront Transcoder is able to support web sites requiring high availability by internetworking with the redundancy engine.
