1. Introduction
Standards governing televisions, set-top boxes and other consumer
electronics devices have for some time been developed with the
Internet in mind. The use of Universal Resource Identifiers (URIs)
[RFC 2396] is now commonplace, including for the purpose of
identifying resources delivered by way of terrestrial, satellite
and cable broadcasts.
For this purpose, a URI scheme was developed as part of the Digital
Video Broadcasting (DVB) suite of standards specifically for the
purpose of identifying broadcasts delivered by way of DVB-compliant
broadcasting systems.

URI scheme syntax.
See Table 1 of [ETSI TS 102 851]
URI scheme semantics.
The dvb scheme references services and resources which are transmitted
using Digital Video Broadcasting-compliant broadcasting systems.
Encoding considerations.
See Section 5 of [ETSI TS 102 851]
Applications/protocols that use this URI scheme name.
dvb URIs are used throughout DVB-compliant broadcasting systems, for
example within Freeview and Freesat in the United Kingdom. They are
also used in TV-Anytime [tva] metadata where it relates to services
transmitted by DVB systems.
Interoperability considerations.
None known.
Security considerations.
Section 7 of RFC 3986 describes general security considerations
for URI schemes. The sections relating to reliability and
consistency, malicious construction, back-end transcoding, rare
IP address formats and semantic attacks all apply to dvb URIs.
The section relating to sensitive information does not apply,
given that dvb URIs do not contain authentication information.

References.
See section 6.
3. Digital Video Broadcasting URI
The DVB URI is defined by [ETSI TS 102 851], and that shall be
considered the authoritative source of the definition of the
scheme-specific-part of the DVB URI.
4. IANA Considerations
Registration will be submitted to IANA for the scheme described in
Section 3.
5. Security Considerations
Section 7 of RFC 3986 describes general security considerations for
URI schemes. The sections relating to reliability and consistency,
malicious construction, back-end transcoding, rare IP address
formats, and semantic attacks all apply to dvb URIs. The section
relating to sensitive information does not apply, given that dvb
URIs do not contain authentication information.
The security considerations of the Digital Video Broadcasting suite
of standards in general are not covered in this document.
