Creating a Digital Library
Selectively Addressable Automatic Alerts
3 Applications of a DAB satellite e.g., WorldSpace
Data Multicasting
- File Broadcast Services
- Provides for the distribution of files to all
recipients of a CUG.
- Audio
- Direct delivery of multiple channels of Pre
recorded/ Live Audio to compact receivers
Data stream transmission Provides the
distribution of data streams to all recipients of
a CUG.
Combined Live Audio Slide Show
(CLASS) Synchronous, live instructor lead
classroom.
Distribution of Emergency Alert
Messages Selectively addressable, secure,
reliable and instantaneous.
4Alert Delivery through WorldSpace
- Covers more than 100 countries with one secure
uplink - Can be addressed by country, group, tier or even
the current location of the receiver - Delivered with a latency of less than 10 seconds
- Automatically triggers a siren/alarm whether or
not the receiver in use - Displays text and automatically switches to audio
information in local language(s) - Caters to diverse requirements/infrastructure
ranging from a sophisticated weather office to a
fisherman out at sea - Goes beyond conventional modes of communication
and supplements/complements other technologies - Survives most hazardous conditions power
failures - Re-used for the daily requirements of the
community (entertainment, agriculture, health,
training..)

6Alert Delivery-Custom Solutions
- Service Options
- Text Only
- Text with Siren
- Text with Shared Audio
- Text with Dedicated Audio
- Alert plus Data Delivery
- Terminal Options (AREA- Addressable Radio for
Emergency Alerts) - AREA-C Audio Alerts for Community Deployment
- AREA-M Alerts for the Mobile User
- AREA-A Audio and Data Alerts for the
Computer-connected User
7AREA-C
- AREA-C is ideal for community deployment
- Immune to loss of main power at the time of the
alert - Battery can be recharged by main or solar power
- External siren controlled by a relay that is
closed by the WorldSpace satellite signal - Option to connect to Public Address system
- Additional box displays all alert parameters
- Radio plays the remotely selected audio channel
that carries authentic information
8AREA-M
- AREA-M is meant for mobile users
- A GPS receiver is connected through the external
box - The box displays the current location of the
receiver before the onset of alert - The alert is triggered only if the current
location of the receiver is within the alert
zone defined by the sender - Can be powered by the vehicle power supply
without using the external battery - Ideal for travelers on land and sea
9AREA-A
- AREA-A is a configuration that connects to the
USB port of a computer - Supports all audio and data services of
WorldSpace - Onset of alert is indicated by a computer
generated siren - Displays all the alert parameters (mandatory
- optional)
- Can support audio/data download, even during
- the alert state
- Can support text-to-speech for the alert

10Alert Delivery-Typical Timeline
- Actions at the Alerting end
- Time 535 pm
- Tsunami warning received from NOAA
- 536 pm (1 minute elapsed)
- Confirm the message
- Type out Alert parameters in the CAP format using
the WorldSpace GUI - Record a short audio message in the local
language - Convert audio file to the required format and FTP
to WorldSpace server - 540 pm (5 minutes elapsed)
- Issue the Alert through WorldSpace text channel
- Insert audio in the alert audio channel
- At the Receive point
- Time 541 pm ( 6 minutes elapsed)
- AREA C sounds a siren, displays alert parameters
and switches the audio to the alert audio
messaging channel whether or not the radio was
being used at this time - AREA-M responds to this alert signal only if its
current position is inside the alert zone. It
also displays the text and plays out the alert
audio channel - AREA-A uses the computer to provide a more
comprehensive display of the alert parameters,
plays the alert audio on the computer and
optionally generates a siren sound on the
computer.
11The Implementation Challenge
- New Technology
- Alert Delivery is the responsibility of a
government agency and usually that agency has no
role or budget for social development - Need for coordination among Ministries
- A comparatively large one-time investment if it
has to scale up to its full potential - Need owners for the activities at non-alert times
(which is hopefully most of the time!) - Continued training of personnel at the hub as
well as in the communities - Sustainability and upkeep of the system

18In Summary
- The Government Agency responsible for Alert
Delivery needs local partners - These partners can be NGOs, Private sector or
other national organizations (Each country has to
choose a model that best suits it) - Non-alert time usage of the system vital not only
for the economics, but for the local acceptance
up keep of the system - If implemented in a large scale, across multiple
projects and over a long duration, these
solutions are cost-effective - Need to bring in regional cooperation and
inter-operability - Important to adopt CAP and establish a
Transmission Hub for all hazards, all media and
all locations - One point generation of the alert and multi point
multiple media dissemination is reliable,
scalable, sustainable and cost effective.
