新的MPEG-4标准的应用将会促进多媒体压缩技术经历另一次重大变化。这一变化将会与1990年MPEG-2压缩标准的推出一样巨大,而且随着视频通信应用的快速发展,MPEG-4标准势将影响到范围广泛的多种应用领域。目前提供音频和数据服务的许多系统都将会扩展引入实时视频服务,而MPEG-4是这方面的关键技术。然而,根据所讨论的ISO标准的不同版本、部分、类和级,MPEG-4这一词可能意味着多种不同技术。
The new MPEG-4 standard will enable multimedia compression technology to undergo another major change. This change will be as dramatic as the introduction of the 1990 MPEG-2 compression standard, and with the rapid growth of video communications applications, the MPEG-4 standard will impact a wide range of applications. Many systems currently providing audio and data services will be extended to include real-time video services, and MPEG-4 is the key technology in this area. However, depending on the version, part, class and level of the ISO standard in question, the term MPEG-4 may imply a number of different technologies.
