Overview

SIST EN 301 192 V1.7.1:2021 (identical to ETSI EN 301 192 V1.7.1:2021) is the DVB specification for data broadcasting. It defines the transport and encapsulation protocols and signalling needed to carry general-purpose data over MPEG-2 based DVB Transport Streams. The document is intended to be used with ETSI EN 300 468 (SI/PSI frameworks) and extends DVB transmission standards to support non‑audio/video services such as software downloads, IP tunnelling, interactive TV and other broadcast‑based Internet services.

Key topics and technical requirements

• Transport & encapsulation protocols for delivering data within DVB Transport Streams (based on MPEG-2 TS).
• PSI (Program Specific Information) and SI (Service Information) rules and required descriptor usage to signal data services (e.g., Data_broadcast_descriptor and specific stream types).
• Data piping and support for asynchronous, synchronous, and synchronized data streaming models.
• Multiprotocol Encapsulation (MPE): encapsulation of IP and other network-layer protocols for broadcast distribution.
• IP/MAC Notification Table (INT) signalling: mechanisms and descriptors for advertising IP/MAC based services, including platform, target and operational descriptors.
• Time Slicing and MPE‑FEC (forward error correction): techniques to improve bandwidth efficiency and robustness for broadband multicast over broadcast channels.
• Descriptor and table definitions (e.g., platform_descriptor_loop, target_descriptor_loop) and semantics required for interoperable implementations.
• Requirements for receiver behaviour, buffer models and interoperability guidance (informative sections).

Practical applications

• Satellite, cable and terrestrial delivery of firmware/software updates and large file broadcasts.
• Broadcast distribution of IP services (IP tunnelling) to enable one‑to‑many delivery of data and Internet content.
• Interactive TV and hybrid broadcast/broadband services, where broadcast carries cached content or multicast data and broadband returns interactivity.
• Content distribution for connected devices (set‑top boxes, connected TVs, IoT devices) that rely on broadcast for efficient one‑to‑many delivery.

Who should use this standard

• Broadcast network designers and operators (satellite, cable, terrestrial)
• Set‑top box, smart TV and receiver manufacturers
• Software vendors providing broadcast file delivery, middleware or MHEG/HbbTV applications
• System integrators deploying hybrid broadcast‑IP services
• Standards and compliance teams ensuring interoperability with DVB ecosystems

Related standards

• ETSI EN 300 468 (SI/PSI signaling) - intended companion standard
• MPEG‑2 Transport Stream specifications - underlying transport format

This standard is essential for any project that needs reliable, standardized methods to encapsulate and signal data over DVB transport streams, ensuring interoperability across broadcast networks and receiver platforms.

Introduction
The DVB System provides a means of delivering MPEG-2 Transport Streams (TS) via a variety of transmission media.
MPEG-2 TSs were primarily intended for the delivery of Video and Audio. The present document introduces data
broadcasting as an extension to the MPEG-2 based DVB transmission standards.
Five different application areas with different requirements for the data transport are addressed. For each application
area a data broadcasting profile is specified in the present document. The following is a short description of the
application areas and the profiles.
Data piping:
• The data broadcast specification profile for data pipes (as defined in clause 4) supports data broadcast services
that require a simple, asynchronous, end-to-end delivery of data through DVB compliant broadcast networks.
Data streaming:
• The data broadcast specification profile for data streaming supports data broadcast services that require a
streaming-oriented, end-to-end delivery of data in either an asynchronous, synchronous or synchronized way
through DVB compliant broadcast networks.
• Asynchronous data streaming is defined in clause 5 and allows the streaming of data without any timing
requirements (e.g. RS-232 data).
• Synchronous data streaming is defined in clause 6 and allows the streaming of data with timing requirements
in the sense that the data and clock can be regenerated at the receiver into a synchronous data stream.
Multiprotocol encapsulation:
• The data broadcast specification profile for multiprotocol encapsulation (as defined in clause 7) supports data
broadcast services that require the transmission of datagrams of communication protocols via DVB compliant
broadcast networks.
• Clause 8 further defines a standard mechanism for signalling IP/MAC services deployed within DVB networks
and enables the implementation of DVB receivers that are completely self-tuning when accessing IP/MAC
streams on one or more transport streams.
• Mechanisms for power-optimized reception and forward error correction for multiprotocol encapsulation are
defined in clause 9.
ETSI
8 Draft ETSI EN 301 192 V1.7.1 (2021-05)
Data and object carousels:
• Data broadcast services that require the periodic transmission of data are called data carousels, and are defined
in clause 10.
• Object carousels (as defined in clause 11) are based on data carousels, and provide an additional hierarchical
structure and further metadata, such as for example needed to build a hierarchical file system.
Higher protocols based on asynchronous data streams:
• The data broadcast specification profile for higher protocols (as defined in clause 12) is based on asynchronous
data streams, and supports the transmission of protocols that require a stream-oriented delivery of
asynchronous data through DVB compliant broadcast networks.
ETSI
9 Draft ETSI EN 301 192 V1.7.1 (2021-05)
1 Scope
The present document specifies transport and encapsulation protocols, and signalling for carrying general purpose data
over DVB Transport Streams. The present document is designed to be used in conjunction with ETSI EN 300 468 [2].
Data broadcasting is an important extension of the MPEG-2 based DVB transmission standards. Examples are the
download of software over satellite, cable or terrestrial links, the delivery of Internet services over broadcast channels
(IP tunnelling), interactive TV, etc.

The DVB Project is an industry-led consortium of broadcasters, manufacturers, network operators, software developers,
regulators and others from around the world committed to designing open, interoperable technical specifications for the
global delivery of digital media and broadcast services. DVB specifications cover all aspects of digital television from
transmission through interfacing, conditional access and interactivity for digital video, audio and data. The consortium
came together in 1993.

Introduction
The DVB System provides a means of delivering MPEG-2 Transport Streams (TS) via a variety of transmission media.
MPEG-2 TSs were primarily intended for the delivery of Video and Audio. The present document introduces data
broadcasting as an extension to the MPEG-2 based DVB transmission standards.
Five different application areas with different requirements for the data transport are addressed. For each application
area a data broadcasting profile is specified in the present document. The following is a short description of the
application areas and the profiles.
Data piping:
• The data broadcast specification profile for data pipes (as defined in clause 4) supports data broadcast services
that require a simple, asynchronous, end-to-end delivery of data through DVB compliant broadcast networks.
Data streaming:
• The data broadcast specification profile for data streaming supports data broadcast services that require a
streaming-oriented, end-to-end delivery of data in either an asynchronous, synchronous or synchronized way
through DVB compliant broadcast networks.
• Asynchronous data streaming is defined in clause 5 and allows the streaming of data without any timing
requirements (e.g. RS-232 data).
• Synchronous data streaming is defined in clause 6 and allows the streaming of data with timing requirements
in the sense that the data and clock can be regenerated at the receiver into a synchronous data stream.
Multiprotocol encapsulation:
• The data broadcast specification profile for multiprotocol encapsulation (as defined in clause 7) supports data
broadcast services that require the transmission of datagrams of communication protocols via DVB compliant
broadcast networks.
• Clause 8 further defines a standard mechanism for signalling IP/MAC services deployed within DVB networks
and enables the implementation of DVB receivers that are completely self-tuning when accessing IP/MAC
streams on one or more transport streams.
• Mechanisms for power-optimized reception and forward error correction for multiprotocol encapsulation are
defined in clause 9.
ETSI
8 ETSI EN 301 192 V1.7.1 (2021-08)
Data and object carousels:
• Data broadcast services that require the periodic transmission of data are called data carousels, and are defined
in clause 10.
• Object carousels (as defined in clause 11) are based on data carousels, and provide an additional hierarchical
structure and further metadata, such as for example needed to build a hierarchical file system.
Higher protocols based on asynchronous data streams:
• The data broadcast specification profile for higher protocols (as defined in clause 12) is based on asynchronous
data streams, and supports the transmission of protocols that require a stream-oriented delivery of
asynchronous data through DVB compliant broadcast networks.
ETSI
9 ETSI EN 301 192 V1.7.1 (2021-08)
1 Scope
The present document specifies transport and encapsulation protocols, and signalling for carrying general purpose data
over DVB Transport Streams. The present document is designed to be used in conjunction with ETSI EN 300 468 [2].
Data broadcasting is an important extension of the MPEG-2 based DVB transmission standards. Examples are the
download of software over satellite, cable or terrestrial links, the delivery of Internet services over broadcast channels
(IP tunnelling), interactive TV, etc.

The DVB Project is an industry-led consortium of broadcasters, manufacturers, network operators, software developers,
regulators and others from around the world committed to designing open, interoperable technical specifications for the
global delivery of digital media and broadcast services. DVB specifications cover all aspects of digital television from
transmission through interfacing, conditional access and interactivity for digital video, audio and data. The consortium
came together in 1993.

Introduction
The DVB System provides a means of delivering MPEG-2 Transport Streams (TS) via a variety of transmission media.
MPEG-2 TSs were primarily intended for the delivery of Video and Audio. The present document introduces data
broadcasting as an extension to the MPEG-2 based DVB transmission standards.
Five different application areas with different requirements for the data transport are addressed. For each application
area a data broadcasting profile is specified in the present document. The following is a short description of the
application areas and the profiles.
Data piping:
• The data broadcast specification profile for data pipes (as defined in clause 4) supports data broadcast services
that require a simple, asynchronous, end-to-end delivery of data through DVB compliant broadcast networks.
Data streaming:
• The data broadcast specification profile for data streaming supports data broadcast services that require a
streaming-oriented, end-to-end delivery of data in either an asynchronous, synchronous or synchronized way
through DVB compliant broadcast networks.
• Asynchronous data streaming is defined in clause 5 and allows the streaming of data without any timing
requirements (e.g. RS-232 data).
• Synchronous data streaming is defined in clause 6 and allows the streaming of data with timing requirements
in the sense that the data and clock can be regenerated at the receiver into a synchronous data stream.
Multiprotocol encapsulation:
• The data broadcast specification profile for multiprotocol encapsulation (as defined in clause 7) supports data
broadcast services that require the transmission of datagrams of communication protocols via DVB compliant
broadcast networks.
• Clause 8 further defines a standard mechanism for signalling IP/MAC services deployed within DVB networks
and enables the implementation of DVB receivers that are completely self-tuning when accessing IP/MAC
streams on one or more transport streams.
• Mechanisms for power-optimized reception and forward error correction for multiprotocol encapsulation are
defined in clause 9.
ETSI
8 ETSI EN 301 192 V1.7.1 (2021-08)
Data and object carousels:
• Data broadcast services that require the periodic transmission of data are called data carousels, and are defined
in clause 10.
• Object carousels (as defined in clause 11) are based on data carousels, and provide an additional hierarchical
structure and further metadata, such as for example needed to build a hierarchical file system.
Higher protocols based on asynchronous data streams:
• The data broadcast specification profile for higher protocols (as defined in clause 12) is based on asynchronous
data streams, and supports the transmission of protocols that require a stream-oriented delivery of
asynchronous data through DVB compliant broadcast networks.
ETSI
9 ETSI EN 301 192 V1.7.1 (2021-08)
1 Scope
The present document specifies transport and encapsulation protocols, and signalling for carrying general purpose data
over DVB Transport Streams. The present document is designed to be used in conjunction with ETSI EN 300 468 [2].
Data broadcasting is an important extension of the MPEG-2 based DVB transmission standards. Examples are the
download of software over satellite, cable or terrestrial links, the delivery of Internet services over broadcast channels
(IP tunnelling), interactive TV, etc.
