General Information

Abstract

The present document applies to InDoor Units (IDUs) for satellite broadcast reception. An indoor unit gets on an input
interface the signal that has been received from satellite and processed by the OutDoor Unit (ODU). It performs carrier
selection, demodulation, audio and video decoding.
IDUs in the scope of the present document demodulate broadcast carriers by means of a Zero IF tuner.
Part of the IDU functionality may be integrated with the ODU. In that case the present document applies to this part of
functionality as well as the remaining part in the IDU.
The indoor unit may be integrated with a domestic television receiver.
The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the
efficient use of radio spectrum in order to avoid harmful interference.

Overview

SIST EN 303 372-2 V1.2.1:2021 defines harmonised requirements for Satellite Earth Stations and Systems (SES), specifically focusing on indoor units (IDUs) for satellite broadcast reception equipment. Developed by the Slovenian Institute for Standardization (SIST) and identical to ETSI EN 303 372-2, this international standard addresses the criteria for access to the radio spectrum, essential for avoiding harmful interference in satellite TV and radio broadcasting environments.

The standard applies to IDUs that process signals received from satellites via an outdoor unit (ODU). The IDU is responsible for functions such as carrier selection, demodulation, and audio/video decoding. Compliance with this standard is critical to demonstrate that the equipment supports the efficient use of the radio spectrum and operates without causing adverse effects to other systems.

Key Topics

  • Scope of Application

    • Applies to indoor units designed for satellite broadcast reception, often integrated with consumer television receivers or combined with ODUs.
    • Covers IDUs that use Zero-IF tuners to demodulate broadcast carriers.
  • Technical Requirements

    • Adjacent Signal Selectivity: Ensures that the receiver can effectively distinguish desired signals from adjacent channel signals to minimize interference.
    • Dynamic Range: Specifies that IDUs must operate effectively over a broad range of input signal levels, accommodating various satellite EIRP and ODU configurations.
  • Compliance and Testing

    • Includes detailed procedures for verifying conformance to adjacent signal selectivity and dynamic range criteria under representative operational environments.
  • Interface Considerations

    • Addresses functionality split between ODUs and IDUs and scenarios where these units are integrated or interact via protocols such as SAT>IP for IP-based delivery.

Applications

This standard is essential for manufacturers, integrators, and operators working with satellite broadcast reception systems, ensuring their equipment:

  • Meets regulatory requirements for radio spectrum usage in the European Union under Directive 2014/53/EU (Radio Equipment Directive).
  • Minimizes harmful interference, promoting reliable satellite TV and radio broadcast reception for end-users.
  • Facilitates integration with domestic television receivers, enhancing home entertainment systems.
  • Supports SAT>IP technology, enabling satellite television signal distribution over IP networks for multi-room or streaming applications.
  • Is suitable for a variety of deployment scenarios, including fixed installations, consumer electronics, and professionally managed broadcast environments.

Related Standards

  • ETSI EN 303 372-1: Covers outdoor units (ODU) receiving in the 10.7 GHz to 12.75 GHz frequency band.
  • EN 50585:2014: Defines the SAT>IP protocol for transporting satellite signals over IP networks.
  • ETSI EG 203 336: Offers guidance on selecting technical parameters when developing Harmonised Standards under the Radio Equipment Directive.
  • Directive 2014/53/EU: Essential for market access, setting out legal obligations for radio equipment in the European market.

Practical Value

Implementing SIST EN 303 372-2 V1.2.1:2021 helps ensure that satellite broadcast reception equipment is:

  • Conformant with European regulatory requirements, providing a trusted basis for CE marking and market access.
  • Engineered for performance and reliability, supporting robust signal demodulation in diverse real-world conditions.
  • Future-proof and interoperable through alignment with current protocols and adjacent standards, supporting seamless integration in evolving satellite broadcast infrastructures.

By adopting this harmonised standard, stakeholders can enhance the quality, compatibility, and compliance of satellite broadcast reception products, benefiting both service providers and consumers across the satellite communication ecosystem.
