1.7 Versioning and Capability Negotiation
This document covers versioning issues in the following areas:
Supported Transports: RTSP Windows Media Extensions are implemented on top of TCP. Also, implementations that require connectionless transmission of multimedia data over an unreliable network service support UDP. For details, see section 2.1.
Protocol Versions: RTSP version 1.0, as specified in [RFC2326], is supported.
Security and Authentication Methods: RTSP Windows Media Extensions support HTTP access authentication, as specified in [RFC2616] section 11.
Localization: RTSP Windows Media Extensions do not specify any localization-dependent protocol behavior.
Capability Negotiation: RTSP Windows Media Extensions perform explicit capability negotiation by using the following mechanisms:
The type attribute in SDP, as specified in section 2.2.5.2.6.
The Supported (section 2.2.6.10) header.
The X-Accept-Authentication (section 2.2.6.14) header.
