Software tool to update ST61 records based on the TVA files


In the process of preparations for the Regional Radiocommunication Conference (RRC-06) it is important to bring the St61 Plan in line with the actual situation, as far as possible.


In many cases the national TVA files contain more accurate and up-to-date data than the corresponding St61 records.

This programme is intended to help the CEPT administrations in the process of updating their ST61 entries, based on the TVA files.


The main functions of this programme are:

  • comparison of St61 records and TVA records in order to identify matching records
  • review and update of data
  • generation of electronic notices according to format specification as given in the ITU circular letter CR/120.

ST61 records are retrieved from the file ‘terrabasebeta.mdb’ which is an MS Access database supplied by the ITU BR on the BRIFIC CD-ROM. This file must be available on the hard disk and the software will read it directly.


TVA files contain analogue TV data in a format that is compliant with the specifications included in Annex 3 to Chester Agreement ’97 and is also provided in the ECC Report 35. A set of the latest TVA files supplied by CEPT administrations are available on the ERO FTP server.


It is recommended to read the User documentation alongside using the software.

The programme is developed for MS Windows platform.
