  ITU-T A.5 justification information for referenced document ETSI EN 302 307-1 V1.4.1 (2014-07) in draft J.298
1. Clear description of the referenced document:
Name: ETSI EN 302 307-1 V1.4.1 (2014-07)
Title: Second generation framing structure, channel coding and modulation systems for Broadcasting, Interactive Services, News Gathering and other broadband satellite applications; Part 1 (DVB-S2)
2. Status of approval:
Approved
3. Justification for the specific reference:
EN 302 307-1 defines a "second generation" modulation and channel coding system for satellite digital multi-programme Television (TV)/High Definition Television (HDTV) services. J.STB-CTS requires a satellite frontend module which needs to refer the existing definition in EN 302 307-1
4. Current information, if any, about IPR issues:
None. IPR info in ETSI are found at https://ipr.etsi.org/
5. Other useful information describing the "Quality" of the document:
EN 302 307-1 has been applied on most of the STB over the world and more than millions of receivers have been manufactured under this specification
6. The degree of stability or maturity of the document:
EN 302 307-1 Version 1.4.1 was published in Jul 2014. It is an approved document by ETSI.
7. Relationship with other existing or emerging documents:
None
8. Any explicit references within that referenced document should also be listed:
