INTRODUCTION The Internet, television, cell phones and other communication portals continually challenge
the status quo of how we see information. This challenge once only considered relevant for
consumer industries has become important for all industries. Think of the evolution of the
slideshow – from transparencies, to PowerPoint, to animated PowerPoint, to hyperlinked-
animated PowerPoint, to automated animated PowerPoint.
Modern day communication requires media rich presentation. Whether it be video, data,
audio or a combination of all three with interactivity, media rich presentation is rapidly
replacing simple printed materials, such as signs, training manuals and corporate memos.
Video and audio are perceived as the best attention getter. Animated graphics are
perceived as a good and less expensive alternative. Interactivity is perceived the best
attention holder.
The next wave of broadcast technology must seamlessly incorporate all media rich
elements. This paper explores how WEGENER’s groundbreaking iPump technology achieves
this goal to enhance educational networks, business networks and broadcast networks.
iPUMP Media Servers - Applications
White Paper - 2
WEGENER’S IPUMP Just what is the iPump? The iPump Media Server may be described as an integrated digital
satellite receiver, IP router, and multi-media server. It is part of WEGENER’s complete end-
to-end solution for content delivery and management.

INTERACTIVE TRAINING Your travel budgets have been cut and your staff reduced. Yet, you are required to increase
worker productivity, increase customer satisfaction and remain abreast of the latest
company information.
Training will probably be a key element to any proposed solution. And, access to compelling
training materials could improve the likelihood the material is viewed and the information is
retained.
While one instructor cannot visit every site or speak to every customer, video can.
With 2 video outputs and LAN access, multiple training classes can be conducted at the same
time from one WEGENER iPump. Training classes can be broadcast based on local schedules
or conducted ad-hoc.
Figure 2 – iPump On-Screen-Display (OSD)
WEGENER’s innovative on-screen-display (OSD) allows one class to be conducted in a fully
interactive manner. As shown in figure 2, the OSD provides a media-rich presentation of content
available to the instructor. Using a remote control, the instructor can scroll through multiple
sections.
White Paper - 5
The CHANNELS section contains live satellite broadcast channels and multiple ‘virtual channels’.
Virtual channels are a collection of seamless linked media and video files. They are presented
with program guides and are perceived to be standalone broadcast channels.
Figure 3 – CHANNEL Program Guide
The LIBRARY section is a warehouse of individual stored content that be viewed at any time for
video-on-demand.
Figure 4 – LIBRARY Section
White Paper - 6
The instructor has the added ability to rewind, fast forward and pause video from the
LIBRARY section. The instructor can also jump to other sections at any time, as shown in
the figure 5 below. The instructor is not confined to a strict viewing schedule or distracted
with VCR tapes and machines.

Text data can be accessed from the DATA section and viewed on a television monitor.
Unlike one-way broadcast technology or video tape distribution, WEGENER’s iPump network
solution can centrally monitor, update, and delete content stored on deployed units.
WEGENER incorporated its expertise gleamed from deploying commercial broadcast satellite
networks to provide iPump networks the same power to accurately address and schedule
content delivery to individual deployed units. Combined with conditional access options, it
creates the framework to generate revenue from content delivery.

STREAMING MEDIA WEGENER iPumps provide another way to continuously push high quality media content to
the edge of a network without tying up valuable IP bandwidth used for site-to-site
communications. This technology bridges satellite delivery with IP infrastructure quickly and
simply.
The iPump accepts and stores files of any type, in addition to the MPEG files. Once files are
stored within the iPump, they are available to other computers1 over a local area network
via File Transfer Protocol, web browser, or Microsoft’s Server Message Block protocol.
The iPump outputs files directly onto the local area network through IP routing or streaming
IP. High quality video is made available for desktop computer in standards-based formats
limiting the need for costly propriety decode software.
Alternatively, peripheral decoder units from WEGENER can be used to display video to
television monitors.
POINT OF SALES DIGITAL SIGNAGE The billboard industry is increasingly embracing technologies that provide more animated
graphics (e.g. revolving panel billboards and large LCD displays). This technology is filtering to
inside the retail building.
More eye catching than print signs, retailers are looking for creative ways to entice shoppers
to stop and buy. Digital signage promises to add flexible and highly targeted messaging.
Past scrolling text and animated graphics, WEGENER iPump peripheral decoders open a door
for a solution that also provides high quality video advertisements in both standard
definition and high definition video formats.
The peripheral decoder is IP based. It is easy to send different program channels to each
decoder. Making use of the CHANNEL section of the iPump media server, content playlists
can be customized for individual departments and play continuous throughout the day.
1 Access to files can be restricted.

Audio will be included. Content can be continuously updated or removed by the central
network operator. Site operators can tweak playlists or request content that best fits their
location.
CREATING VIRTUAL CHANNELS In traditional one-way broadcast environments custom programming usually requires
broadcasting a new separate channel and utilizing precious, expensive satellite bandwidth.
Local advertising requires additional video servers and cuetone devices. For each piece of
customization there are cost and maintenance concerns, such as additional satellite
transponder time, bandwidth consumption and servicing additional pieces of equipment.
An iPump Media Server is one piece of equipment that can receive satellite broadcasts,
store program material and seamlessly combine them to create ‘virtual channels’. Stored
program material can also be combined with live broadcast content.
A central network operator could easily distribute multiple customized playlists, sending
them to specific regions or groupings of iPumps or even to individual iPumps. Each iPump
uses the playlists to generate ‘virtual channels’ from stored program materials. As shown in
figure 6, an iPump can create a multi-channel environment. No distinction is given to the
viewer between a live channel and a ‘virtual channel’.
Figure 6 – iPump “Channel” Section
White Paper - 9
Repetitive broadcasts can be sent once and either scheduled to play continuously, play at a
scheduled time or play program material in a random sequence continuously. Updates,
modifications and deletions can be made by the central network operator without local
intervention. This lessens the need for transponder satellite time or eliminates the need for
VCR tape distribution.
TIME SHIFTED PROGRAMMING Satellite programmers currently repeat programs or use a separate satellite feed to
overcome east and west coast time zone differences.
On an iPump Media Server, time shifted programming would be a ‘virtual channel’. Programs
are recorded to the iPump Media Server while simultaneously playing out local content. The
stored content is then scheduled to play at the later appropriate time.
An iPump Media Server allows programmers to create modified channels without having to
duplicate satellite transmission feeds. The Broadcast option of the iPump Media Server
product family supports 4:2:2 video decoding and SDI output - ideal for commercial digital
distribution.
WEGENER’s network control system is a mature product and the result of years of
experience with commercial satellite broadcast applications. It will ensure a satellite
programmer’s content gets to the right location, at the right time, in a secure manner.
VIDEO ON DEMAND Video-on-demand or VOD is the use of technology that allows viewers to watch specific
programs on a non-scheduled basis from a video server. Cable operators utilize remote
servers and digital cable set-top devices. Personal video recorders (PVRs) use a video
receiver, a set-top media server (some are integrated into a receiver device) and require
the user to specify what programs to record.
The iPump media server is both a satellite receiver and media server. A central network
operator can ‘push’ content to the distributed iPumps or respond to requests for content.

Individual stored media files can be accessed via the on-screen-display, web browser or LAN
connection. Here are a few examples of possible applications:
▪ Internal training sessions scheduled on an ad hoc basis
▪ External demonstrations for customers
▪ Films or documentaries made available to schools
▪ News clips or sporting highlights distributed from a major network to regional sites
▪ Corporate messaging or speeches for remote sites
▪ Distance education
In fully implemented iPump network solutions remote iPump users can access the central
content management system to view what new content is available and contribute content.
Network operators can schedule delivered content for deletion. Conditional access can be
used to generate revenue
SUMMARY Modern day communication requires media-rich presentation. WEGENER strongly believes
that the next wave of broadcast technology must seamlessly incorporate all media-rich
elements.
IPump Media Servers give networks the ability to combine media storage, IP routing and
satellite broadcast technology. These multifunctional devices can enhance broadcast
networks, educational networks, product marketing and business networks.

APPENDIX A – Technical Overview
IPUMP PRODUCT INFORMATION The name iPump represents the idea of an i nformation Pump. Information may be in the
form of video, audio, images, data files or anything at all which may be put in the form of
1’s and 0’s. The iPump may output this information upon receipt or place it in storage for
later transmission, streaming or viewing.
The iPump is designed for applications where the user wants to have the option of either
centralized or local control of media delivery. In a typical network as shown in figure 7,
transmitted content is distributed to an iPump via satellite and output in a variety of forms.
Figure 7 – iPump Media Server Interfaces
White Paper - 1 2
Programs can be viewed via a video monitor or transmitted via an Ethernet connection to
desktop computers on a local area network. The iPump also uses the Ethernet connection to
provide a return path to the originating location of the network. This gives feedback of
operational status, usage data, and assures file transfer to the network manager.
At the same time, program streams may be stored on the hard disk drive inside the iPump.
As shown in figure 8, the iPump can store over 200 hours of video content.
