IMAGE VIEWING AND ANNOTATION TOOLS FOR EVERY WEB ENVIRONMENT

Use the streamer to deliver significant performance improvements for all users viewing multi-page PDF and TIFF documents. The Document Streaming Server Module is a Servlet (server-side) module which ensures delivery of just, and only just, the right amount of information required for viewing any given page. This may seem like an obvious thing to do. Well, we think so too, but just about all other viewing software (excluding Daeja of course) often sends large quantities of data to a viewer that is never used or required for viewing. This module resolves this in a number of unique (and patent pending) ways...

What does the Document Streaming Server Module do to improve performance?

As documents become larger, time to view becomes longer and longer and it's ultimately all down to the sheer amount of data needed to download to the viewer.

There have been numerous attempts to deal with this issue and these attempts usually fall into one of two categories. Either some kind of server-side pre-rendering (usually into an image format supported by the viewer) in order to permit transfer of pages on demand, or pre-separation of pages (into separate PDF files) so that each can be viewed separately without the need to download the whole document.

The problem with pre-rendering is that it is only a perceived improvement; this ‘improvement’ is only so long as just one or two pages are viewed. When viewing more pages, it actually increases network traffic (image based versions of PDF documents are larger than PDF originals) and so will ultimately lead to reduced network performance and longer overall delays; especially when the number of documents and users viewing them increases.

The problem with the latter approach is that it results in users losing the ease of viewing that comes with simply clicking on the 'next page' button, but instead having to manually select and download those pages required. It also does not reduce network traffic particularly if users have a tendency to view all pages or print all pages.

Daeja's Document Streaming Server Module overcomes these issues. Not only does it remove the need for pre-rendering and pre-page separation, it maintains the ease of multi-page viewing while reducing the amount of data needed to transmit each page and without losing page quality or fidelity.

The Document Streaming Server Module uniquely optimizes the original page information for web usage, which on its own, would lead to huge benefits but combined with our streaming system yields so much more.

Daeja's solution works on-demand with your existing PDF documents. The Document Streaming Server Module takes PDF documents on the server and sends reduced size PDF documents to the viewer. It's even possible to view pages of a multi-page document randomly without having to wait for prior pages to first be downloaded and it's all entirely transparent to the user.

Daeja's solution will integrate into any web based or web enabled Enterprise Content Management (ECM)/DM system, and so whether your users view one or two pages, or all pages, Daeja's unique PDF streaming technology will lead to benefits for all.

Enhance further using pre-fetching

The Document Streaming Server Module can be enhanced through the use of ViewONE Pro's pre-fetching which can be set to pre-download and cache the pages in advance of the one being viewed by a user. This operation is performed by ViewONE client software on the users own machine. See our HTML Manual for further information on the "PrefetchPages" configuration option.

Test for yourself online now - with your own documents

Our online demonstration uses a 20Mb, 783-page TIFF file and a 10Mb, 1,287-page PDF file streamed from our own web server to illustrate the enormous performance gains that can be achieved with the DSSM. You can even upload your own documents! Please click here to view the online demo.
