TABLE OF CONTENTS

Article 1. The accompanying Circular sets forth economic-technical norms for measurement and inspection activities in the broadcasting and television sector, including:

Norms for measuring electromagnetic field exposure of radio and television stations. Norms for measuring the quality of IPTV (Internet Protocol Television) service on public fixed telecommunications networks. Norms for measuring the quality of digital cable television DVB-C signals at subscriber connection points. Norms for measuring analog cable television signals at subscriber connection points. Norms for measuring digital terrestrial DVB-T2 broadcast signals. Norms for measuring the quality of digital satellite DVB-S and DVB-S2 television signals at receiving points. Norms for measuring the quality of digital terrestrial DVB-T2 television signals at receiving points.

Article 2. Scope of Standards

Economic-technical norms for measurement and inspection activities in the broadcasting and television sector set forth in this Circular specify the maximum direct costs required to complete a measurement and inspection task in the broadcasting and television sector, including: Material costs, labor costs, machinery and equipment costs. These norms do not include transportation costs for labor, machinery, and equipment, nor indirect costs allocated within each measurement and inspection task.

Article 3. Applicability

State budget-funded agencies conducting measurement and inspection activities in the broadcasting and television sector shall comply with the provisions of the law. Agencies conducting measurement and inspection activities in the broadcasting and television sector without using state budget funds are encouraged to apply the economic-technical norms set forth in this Circular.

Article 4. Application of Standards

Economic-technical norms for measurement and inspection activities in the broadcasting and television sector serve as a basis for relevant agencies and units to establish prices, budgets for implementing measurement and inspection activities in the broadcasting and television sector, and manage economics during the implementation of such activities.

Article 5. Implementation Provisions

This Circular takes effect from June 1, 2018. In cases where measurement activities have special characteristics and the application of the norms issued with this Circular is inappropriate, the agency conducting the measurement activity shall develop norms and report them to the managing authority for the Ministry of Information and Communications to consider and issue or approve for the managing authority to issue. During the implementation process, if there are difficulties or obstacles, agencies and units are requested to report to the Ministry of Information and Communications for consideration and resolution.
