A Primer on the T.120 Series Standard - http://www.lotus.com/products/sametime.nsf/standards/8DDB25B6C08E70E5852566640072FCD2
The T.120 standard contains a series of communication and application protocols and services that provide support for real-time, multipoint data communications. These multipoint facilities are important building blocks for a whole new range of collaborative applications, including desktop data conferencing, multi-user applications, and multi-player gaming.
Multipoint Communication Service (MCS) - T.122, T.125; Transport Stacks - T.123; Generic Conference Control (GCC) - T.124; Generic Application Template (GAT) - T.121; Still Image Exchange and Annotation (SI) - T.126; Multipoint Binary File Transfer - T.127.

Key H.323 Terms - http://www.databeam.com/h323/h323primer.html
H.323 is an umbrella recommendation from the International Telecommunications Union (ITU) that sets standards for multimedia communications over Local Area Networks (LANs) that do not provide a guaranteed Quality of Service (QoS). The H.323 standard provides a foundation for audio, video, and data communications across IP-based networks, including the Internet.
H.323 is part of a larger series of communications standards that enable videoconferencing across a range of networks. Known as H.32X, this series includes H.320 and H.324, which address ISDN and PSTN communications, respectively.

Taxonomy of Communication Requirements for Large-scale Multicast Applications
by P. Bagnall, B. Briscoe, A. Poppitt. - RFC2729. - ftp://ftp.isi.edu/in-notes/rfc2729.txt
The intention of this memo is to define a classification system for the communication requirements of any large-scale multicast application (LSMA). It is very unlikely one protocol can achieve a compromise between the diverse requirements of all the parties involved in any LSMA. It is therefore necessary to understand the worst-case scenarios in order to minimize the range of protocols needed. Dynamic protocol adaptation is likely to be necessary which will require logic to map particular combinations of requirements to particular mechanisms. Standardizing the way that applications define their requirements is a necessary step towards this.
Classification is a first step towards standardization.

Open standard aims to provide an extensible framework to enable controlled delivery of real-time data, such as audio and video.
Caching Support in Standards-based RTSP/RTP Servers by Jay Geagan, Mike
Kellner, Alagu Periyannan - http://www.ietf.org/internet-drafts/draft-periyannan-rtsp-caching-00.txt
This document presents the issues facing streaming media caching. It proposes a set of mechanisms to enable streaming media caching between standards-based RTSP/RTP servers and proxies. Streaming media caching refers to the process through which streaming content is dynamically replicated closer to users so as to provide a better viewing experience. A list of RTSP ehancements and open issues are presented. This document is intended to be a starting point for discussion between various parties interested in standardizing the mechanism used by RTSP/RTP servers to enable streaming media caching.

Uniform Resource Identifiers for Television Broadcasts by D. Zigmond,
World-Wide Web browsers are starting to appear on a variety of consumer electronic devices, such as television sets and television set-top boxes, which are capable of receiving television programming from either terrestrial broadcast, satellite broadcast, or cable. In this context there is a need to reference television broadcasts using the URI format described in [RFC 2396]. This document describes a widely-implemented URI scheme to refer to such broadcasts.
Stream URI Scheme by F. Kenji, K. Shinobu, T. Tsuyoshi
This document describes the Stream Uniform Resource Identifier which allows Internet clients to have direct access to multimedia streams.

Multimedia Metadata format and Markup language
Synchronized Multimedia: Synchronized Multimedia Integration Language
W3C Recommendation: Synchronized Multimedia Integration Language (SMIL) 1.0 Specification - http://www.w3.org/TR/REC-smil
This subset of XML (Extensible Markup Language) enables synchronisation of multimedia elements (video, sound, still images. text). SMIL (pronounced "smile") streams multiple movies, still images, and sound separately but co?rdinates their timing.
