Objective
The Radiate Project will trial and promote the new ITU standard for digital broadcasting of audio and data in the AM bands at frequencies below 30 MHz using a system developed by the DRM consortium. The Trial will utilise prototype transmitter exciters for both the Short and Medium Wave bands, using modified existing transmitters located around the world and received on prototype receivers. The objectives of the trial are to: confirm the operational effectiveness of the system and support submissions to the ITU for final acceptance of the DRM system; demonstrate the DRM system's compatibility with existing transmissions; prove the commercial viability of the system and support the development of commercial support tools and equipments; promote its acceptance within and outside Europe; and ensure that European and associated organisations are well placed to take a leading role in the utilisation and commercial exploitation of the new medium.
Objectives:
To verify that digital broadcasting in the AM bands, 30MHz is viable using the standard and system developed by the DRM consortium.
To confirm that the DRM system features operate as expected over a broad range of reception conditions
To show that the expected improvement in both audio quality and reception reliability is consistently achieved
To demonstrate data transmission using the DRM system
To confirm that the ITU requirements for digital systems are met
To demonstrate that DRM broadcasts comply with broadcast legislation and can co-exist with analogue broadcasts
To gain experience in adapting existing transmitters for DRM use
To collect and analyse data from the transmitters and receivers
To gain sufficient operating experience to enable the partners, to have an advantage in the operations and commercial exploitation of the medium when DEM services are introduced
To produce a frequency and network planning recommendation for digital broadcasting in the AM bands below 30MHz.
Work description:
The RADIATE Project will verify the new standard proposed to the ITU by the DRM consortium for digital broadcasting of audio and data in the AM bands at frequencies below 30MHz using a system developed by the DRM consortium
An evaluation criteria document will be produced defining the usability, performance and economic criteria against which the system will be evaluated.
A test plan will then be drawn up in consultation with the DRM technical committee. This plan will describe in detail the transmitters which will transmit to which locations and when, the locations of the prototype reference receivers within the target area for the transmission. The planning stage will also define the test signal for both audio and data. Existing transmitter exciters, receivers and software will be modified or adapted to enable them to work with the new DRM system. Existing transmitters belonging to the partners will be modified to accept the prototype equipment while staying within the ITU regulations
The signal will be received and recorded by the prototype receivers for analysis. The analysis of the data will seek to confirm that the system operates correctly over a broad range of frequencies, propagation conditions and signal paths. The analysis will commence with the first transmissions providing feedback to the transmitter operators and manufacturers such that modifications of the transmitter and receiver equipment can take place during the trial. The results of the analysis will provide data on the systems performance for the RADIATE partners, DRM technical committee and the ITU. The DRM system and digital broadcasting in the AM bands below 30MHz will be demonstrated at broadcasting conferences and exhibitions around the world to encourage the uptake of the technology. A frequency planning and Network planning recommendation will be produced based on the data gathered during the trial. It will provide data to allow the modification of the existing service planning tool
Milestones:
Delivery of the Trial specification document Prototype
Transmitter Exciters and Receivers and Software delivered
Field Trial Start
Field Trial Finish
Interim System Performance Report
Final system Performance report
Recommendation for service planning completed
The results are expected to show that the new system is viable for the digitalisation of the AM bands below 30MHz. That the prototype exciter and receivers are capable of broadcasting the digital signal and can form the basis of the production models.
