What is DrTV?

Main advantages

One single transmitter can reach millions of people anywhere, anytime and with unlimited coverage possibilities ranging from 100 km² up to well over 5’000’000 km² (depending on the antenna system)

DrTV offers free-of-charge reception and is independent of any gatekeepers and third party providers like satellites, cable networks or internet.

DrTV keep citizens living abroad informed and up-to-date about what is going on in their home country.

One video stream can be accompanied by several audio streams, allowing for synchronous multi-language support

DrTV is a new application based on DRM.It enables small-scale video and audio services

for cost efficient large area distribution of information and education programs

ONE transmitter covers huge areas, large population and several countries!

Shortwave transmission – the most economic way to reach millions of listeners

What makes DrTV work

DrTV is a new DRM application. It is made possible by enhancement of the Coder (ContentServer) and Decoder (Receiver) and enlargement of the transmitter bandwidth to 20 kHz.

To receive and play DrTV, the receiver (like Uniwave) must have enough CPU power (Central Processing Unit) to be able to decode DRM 20 kHz bandwidth.

The receiver must be able to convert and display the picture stream on the monitor.

Thomson ContentServer

Thomson ContentServer as an asset for any radio broadcast chain

The newest model has been enhanced to enable DrTV

In addition to DrTV, the Content Server provides numerous advanced and very useful services like:

Journaline EPG (Electronic Program Guide) DRM Text messages Slide shows DRM signaling DRM multiplex generation

One ContentServer can send simultaneously the signal to any number of DRM modulators at various transmitter sites

Where is DRTV with Shortwave uniquely useful ?

Store-and-Forward video of news programming for

Businessmen and expatriates in areas with poor Internet access

For national fishing fleets

For citizens travelling abroad with limited Internet access

For distance learning projects in remote areas and for nomadic populations

For keeping citizens informed and connected in catastrophic situations, where local broadcast and communication infrastructure has broken down

January 10

International Shortwave Transmissions

With expanding international trade and migration, more and more people are traveling and living abroad

Mobile TV over shortwave is an interesting option to cover huge areas with news services far away from home

January 10

Example 1: International News Service (High Sea conflict between Korea and South Korea)

Sample from a real DRTV transmission in short wave

Example distance learning system

For fast growing economies such as India, education is a priority, but not easy to achieve when the kids and students are in remote areas, small villages and when there is limited electricity and thus internet

January 10

Example distance learning system

DrTV enables the highly effective use of distance learning in combination with the Uniwave receiver

Reception is possible anywhere in the world - any time of day - and with an absolute minimum of new infrastructure

January 10

Keeping People in disaster areas informed

Shortwave broadcast is worth its weight in gold when it comes to reaching trouble spots and disaster areas at short notice

When natural disaster strikes, communications infrastructure is usually strongly affected at the exact time when local populations require reliable news and information

DrTV can reach into such disaster areas from far away, guiding, informing and comforting the stricken people

January 10

Keeping national fisher fleets informed

Store-and-forward video programming (news on demand)

Shortwave broadcast can reach fishing fleets in far away places

All they need is a shortwave receiver - no other complicated and expensive infrastructure is required

January 10

Next Steps

Detailed field tests Preparation of suitable content (different kinds of videos, etc.) Simulation/calculation of expected service parameters like field

strength, mode, protection, antenna parameters, etc.

Set-up of measurement and monitoring Define measurement program Mobile reception Stationary reception Spectrum measurement Service reliability Service quality

Measurement of minimum requirements for transmitter specifications
