SIST EN 301 172 V1.1.1:2003 is the Slovenian adoption of ETSI EN 301 172 V1.1.1, a European telecommunications standard on generic coding of moving pictures and associated audio information. It specifies the coded representation, decoding process, and system layer for digital storage media and digital video communication, and it is aimed at implementers working with the related ITU-T recommendations.

What does SIST EN 301 172 V1.1.1:2003 specify?

SIST EN 301 172 V1.1.1:2003 sets out an ETSI-endorsed framework for generic video and associated audio coding. Its stated focus is studies on video coding for ATM and B-ISDN networks, so it is relevant where coded video must fit into telecommunications transport and service environments.

The document is an endorsement of ITU-T Recommendations H.262 (1995) and H.222.0 (1995) without modification. In practice, that means readers should use the ITU-T texts as the technical substance, while this European Standard records their adoption by ETSI and the national standardization route.

What are the key requirements of SIST EN 301 172 V1.1.1:2003?

The most important point in SIST EN 301 172 V1.1.1:2003 is that it adopts the ITU-T coding and system specifications as-is. For an engineer or buyer, that means conformance is tied to the two referenced ITU-T Recommendations, not to a separate ETSI rewrite.

• The introduction says the document addresses the coded representation of pictures information for digital storage media and digital video communication. In practice, this is the core use case for any implementation that has to encode, transport, or decode moving pictures in a telecom environment.
• The same introduction says the standard specifies the decoding process. That matters because decoder behavior has to match the adopted coding rules if equipment is expected to interoperate.
• The introduction also says it specifies the system layer of the coding. This is important for integration work, because system-layer rules affect how coded video and audio are packaged and handled around the codec itself.
• The endorsement notice states that ETSI approved the texts of ITU-T Recommendations H.262 (1995) and H.222.0 (1995) without modification. In practice, implementers should look to those recommendations for the technical details.
• The scope metadata points to ATM and B-ISDN networks. That tells network and system designers that the standard sits in a telecommunications context, not just in isolated storage or consumer-video use.
• The foreword gives the transposition dates for the European Standard. For procurement and compliance work, this helps identify the standard’s formal status in the national standardization system.

What terms does SIST EN 301 172 V1.1.1:2003 define?

• ATM - Asynchronous Transfer Mode, a telecommunications transport technology mentioned in the scope as part of the network context for video coding.
• B-ISDN - Broadband Integrated Services Digital Network, the broadband network environment named in the scope.
• ETSI - European Telecommunications Standards Institute, the body that produced the European Standard and endorsed the ITU-T texts.
• EN - European Standard, the document type used for this publication.
• IPR - Intellectual Property Rights, highlighted in the front matter because essential or potentially essential IPRs may apply to the standard.
• H.262 - ITU-T Recommendation H.262 (1995), one of the two recommendations endorsed by this standard.
• H.222.0 - ITU-T Recommendation H.222.0 (1995), the other endorsed recommendation, associated here with the coding system layer.

Who uses SIST EN 301 172 V1.1.1:2003?

SIST EN 301 172 V1.1.1:2003 is used by codec and decoder developers, telecom equipment manufacturers, and system integrators who need video coding aligned with ITU-T H.262 and H.222.0. It is also relevant to quality and compliance teams checking whether a product follows the adopted European and ITU-T framework for coded video and associated audio information.

Network engineers working on ATM or B-ISDN-related video services can use it to align transport and coding choices. Buyers and technical evaluators can use it to identify the correct standard family before specifying interoperable video equipment.

Which standards are used with SIST EN 301 172 V1.1.1:2003?

Standard	What it contributes
ITU-T Recommendation H.262 (1995)	Provides the video coding recommendation adopted by the European Standard.
ITU-T Recommendation H.222.0 (1995)	Provides the system-layer recommendation adopted by the European Standard.

What does the SIST EN 301 172 V1.1.1:2003 document contain?

The document contains ETSI’s endorsement notice showing that the two ITU-T Recommendations were approved without modification. It also includes the foreword, introduction, IPR notice, copyright notice, and document history.

For practical use, this means the publication serves as the official European and Slovenian adoption wrapper around the ITU-T technical texts. The useful technical content for implementation is the coding, decoding, and system-layer material identified in H.262 and H.222.0, while this document records how that content is standardized by ETSI.
