Stiemerling, Ed. Status: Standards Track Stream: IETF Date: December 2016 Mailbox: schulzrinne@cs.columbia.edu, anrao@cisco.com, robla@robla.net, magnus.westerlund@ericsson.com, mls.ietf@gmail.com Pages: 318 Characters: 746422 Obsoletes: RFC 2326 I-D Tag: draft-ietf-mmusic-rfc2326bis-40.txt URL: https://www.rfc-editor.org/info/rfc7826 DOI: 10.17487/RFC7826 This memorandum defines the Real-Time Streaming Protocol (RTSP) version 2.0, which obsoletes RTSP version 1.0 defined in RFC 2326. RTSP is an application-layer protocol for the setup and control of the delivery of data with real-time properties. RTSP provides an extensible framework to enable controlled, on-demand delivery of real-time data, such as audio and video. Sources of data can include both live data feeds and stored clips. This protocol is intended to control multiple data delivery sessions; provide a means for choosing delivery channels such as UDP, multicast UDP, and TCP; and provide a means for choosing delivery mechanisms based upon RTP (RFC 3550). This document is a product of the Multiparty Multimedia Session Control Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
