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. 2. dvb URI Registration URI scheme name. dvb McRoberts Expires December 29, 2010 [Page 2] Internet-Draft URIs for DVB June 2010 Status. provisional 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. Contact. Mo McRoberts Author/Change controller.

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. 6.
