本文讨论了与IP多媒体业务（如视频会议）的传输和控制相关的技术问题，这些业务涉及异构终端。特别是，它描述了IETF SIP（会话发起协议）和ISO MPEG-4 DMIF（交付多媒体集成框架）会话和呼叫控制信令协议之间的互通的实验系统的设计和实现。该IP视频会议互通系统由两个核心单元组成，用于支持从DMIF域到SIP域（即DMIF 2SIP单元）和从SIP域到DMIF域（即SIP 2DMIF单元）的音视频流的传送。这些单元执行各种转换功能，用于在IP联网环境上透明地建立和控制多媒体会话，包括会话协议转换、服务网关转换和地址转换。
This article discusses technical issues related to delivery and control of IP multimedia services, such as videoconferencing, involving heterogeneous end terminals. In particular, it describes the design and implementation of an experimental system for interworking between IETF SIP (session initiation protocol) and ISO MPEG-4 DMIF (delivery multimedia integration framework) session and call control signaling protocols. This IP videoconferencing interworking system is composed of two core units for supporting delivery of audio-video streams from a DMIF domain to a SIP domain (i.e. DMIF2SIP unit) and from a SIP domain to a DMIF domain (i.e. SIP2DMIF unit). These units perform various translation functions for transparent establishment and control of multimedia sessions across an IP networking environment, including, session protocol conversion, service gateway conversion and address translation.
