Overview

SIST EN 301 701 V1.1.1:2003 defines the use of Orthogonal Frequency Division Multiplexing (OFDM) modulation for digital video broadcasting via microwave digital terrestrial television. Developed by the Slovenski inštitut za standardizacijo (SIST) and based on European Telecommunications Standards Institute (ETSI) specifications, this standard allows broadcasters and manufacturers to leverage DVB-T approaches not just for UHF/VHF terrestrial delivery, but also for microwave transport layers. The objective is to enable high-quality, robust transmission of digital television, data, and multimedia services using microwave frequencies.

By referencing DVB-T standards and extending them for microwave applications, SIST EN 301 701 supports evolving broadcast infrastructures, facilitating the adoption of advanced modulation schemes such as OFDM across different frequency bands.

Key Topics

• DVB-T Compatibility: The standard ensures that current DVB-T framing structure, channel coding, and modulation are directly applicable to microwave transport, promoting interoperability and system uniformity.
• OFDM Modulation: Emphasizes the use of OFDM for microwave frequency channels, improving resistance to multipath interference and enabling efficient frequency usage.
• Frequency Translation: Outlines processes for converting signals between UHF/VHF and microwave bands, ensuring flexible channel allocation.
• Performance Requirements: Details phase noise and frequency stability requirements exclusive to microwave OFDM deployments, which are generally more demanding than those for UHF/VHF.
• Spectrum Characteristics: References spectrum masks and bandwidth management as established in DVB-T standards, adapted for the unique environment of microwave bands.

Applications

The practical applications of SIST EN 301 701 include:

• Digital Terrestrial Television (DTT) over Microwave: Expanding DVB-T systems to utilize microwave channels for digital TV broadcast, particularly in scenarios where UHF/VHF spectrum is limited or for distribution over challenging terrain.
• Multi-Program Microwave Services: Supporting the simultaneous broadcast of multiple digital TV and data channels via a single microwave transport link, using robust OFDM modulation techniques.
• Backhaul and Distribution Networks: Enabling operators to build efficient backbone links to transmit DVB-T signals between geographically separated transmitters or from studios to transmitter sites.
• Interoperable Broadcast Equipment: Facilitating the development of receivers and set-top boxes that are compatible with both UHF/VHF and microwave DVB-T streams, aiding consumer electronics innovation.

Related Standards

SIST EN 301 701 V1.1.1 builds upon and interoperates with several relevant standards in digital broadcasting:

• EN 300 744: Digital Video Broadcasting (DVB); Framing structure, channel coding and modulation for digital terrestrial television.
• EN 300 748: DVB Multipoint Video Distribution Systems (MVDS) for frequencies at 10GHz and above.
• EN 300 749: DVB Microwave Multipoint Distribution Systems (MMDS) for frequencies below 10GHz.
• ISO/IEC 13818: Information technology - Generic coding of moving pictures and associated audio information (MPEG-2 standards).
• EN 300 421: DVB for 11/12GHz satellite services.
• EN 300 429: DVB for cable systems.

Compliance with SIST EN 301 701 ensures broadcasters and equipment manufacturers are aligned with European best practices for digital television broadcasting, both terrestrially and via microwave, achieving efficient spectrum usage and reliable, high-quality digital content delivery.
