SIST ETS 300 801 E1:2003
(Main)Digital Video Broadcasting (DVB); Interaction channel through Public Switched Telecommunications Network (PSTN)/ Integrated Services Digital Networks (ISDN)
General Information
- Abstract
This ETS is the baseline specification for the provision of return channel based on PSTN and ISDN to DVB Systems. It is noted that the DVB does not intend to specify a return channel solution associated to each broadcast system because the interoperability of different delivery media to transport the return channel is desirable. Therefore the PSTN/ISDN solutions for the return channel apply to satellite, cable, SMATV, terrestrial, MMDS or any future DVB broadcasting system. The solutions here provided for return channel through PSTN/ISDN are a part of a wider set of alternatives to implement interactive services for DVB broadcasting systems.

Overview
SIST ETS 300 801 E1:2003 is a key European standard defining baseline specifications for implementing a return interaction channel using the Public Switched Telecommunications Network (PSTN) and Integrated Services Digital Networks (ISDN) in Digital Video Broadcasting (DVB) systems. Issued by the Slovenian Institute for Standardization (SIST), this standard provides a unified framework for enabling interactive services by allowing the DVB system to communicate bi-directionally with end users through commonly available telecommunication networks.
The specification focuses on interoperability and is applicable to a broad range of DVB delivery platforms-including satellite, cable, terrestrial, SMATV, and MMDS. The document does not tie the return channel solely to any particular broadcast system, ensuring that new and future DVB technologies can utilize PSTN/ISDN for interactive applications.
Key Topics
- Return Channel Specification: Definition of protocols and physical interfaces to support return path communications from the user to the DVB service provider over PSTN or ISDN.
- System Architecture: Reference model describing how interaction channels integrate with existing broadcast channels in DVB systems.
- Bi-directional Communication: Guidelines for implementing both broadcast (service provider to user) and interaction (user to service provider and vice versa) channels.
- Protocol Stack Model: Focus on the physical and transport layers; application layer remains open for market innovation.
- Physical Interfaces: Requirements for connecting user terminals to PSTN/ISDN through modems-both internal and external.
- Calling Procedures: Methods and requirements for initiating, maintaining, and terminating return channel connections, including emergency call provisions and line sharing.
Applications
SIST ETS 300 801 E1:2003 delivers strong practical value in enabling interactive DVB services over widely available telecommunication infrastructures. Key applications include:
- Interactive Television: Facilitates features such as voting, shopping, gaming, information retrieval, and user feedback, which require upstream communication from the end user.
- Enhanced User Engagement: Supports real-time interaction between viewers and content providers, making services more dynamic and responsive.
- DVB Services Across Platforms: Ensures consistent support for return channel functionality regardless of whether DVB is delivered via satellite, cable, terrestrial, or other systems.
- Cost-Effective Deployment: Utilizes existing PSTN and ISDN networks, reducing the need for dedicated connectivity solutions for interactive services.
- Future-proofing DVB Systems: By standardizing at the interaction layer, the solution remains relevant as broadcast technologies evolve.
Related Standards
To ensure compatibility and comprehensive coverage, SIST ETS 300 801 E1:2003 references and works alongside several important standards:
- ETS 300 001: General technical requirements for equipment connected to analogue PSTN subscriber interfaces.
- ETS 300 011, ETS 300 012: ISDN user-network interface specifications.
- ETS 300 402, ETS 300 403: Data link and network interface signaling for ISDN.
- EN 50201: Interface requirements for DVB Integrated Receiver Decoders.
- ETS 300 802: Network independent protocols for DVB interactive services.
- ITU-T Recommendations V.21 to V.34, V.42: Modem and data communication standards.
- DAVIC Specifications: Reference models for digital audio-visual interactive services.
Practical Value
By leveraging SIST ETS 300 801 E1:2003, broadcasters, network providers, and system integrators can confidently deploy interactive DVB services using reliable, standardized methods for the return communication channel. The standard guarantees interoperability, simplifies integration across various platforms, and supports the evolving needs of digital broadcasting in a cost-effective manner. This approach future-proofs system investments and promotes richer, more engaging user experiences in digital video services.

Digital Video Broadcasting (DVB) Project
Founded in September 1993, the DVB Project is a market-led consortium of public and private sector
organizations in the television industry. Its aim is to establish the framework for the introduction of
MPEG-2 based digital television services. Now comprising over 200 organizations from more than
25 countries around the world, DVB fosters market-led systems, which meet the real needs, and
economic circumstances, of the consumer electronics and the broadcast industry.

1 Scope
This European Telecommunication Standard (ETS) is the baseline specification for the provision of Return
Channel (RC) based on PSTN and ISDN to Digital Video Broadcasting (DVB) systems.
It is not intended to specify a RC solution associated to each broadcast system because the
inter-operability of different delivery media to transport the RC is desirable. Therefore the PSTN/ISDN
solutions for the RC apply to satellite, cable, SMATV, terrestrial, MMDS or any future DVB system.
The solutions here provided for RC through PSTN/ISDN are a part of a wider set of alternatives to
implement interactive services for DVB systems.
