In this research project, we establish the multimedia networking technology in both of network and end systems, which multimedia application can utilize to guarantee QoS.We first consider an efficient transport mechanism for the data communication, which is based on the rate based congestion control. The rate-based congestion control algorithm has recently been standardized by the ATM Forum. Our study is to proposed the traffic control method suitabe for the environment that the motion video transmission co-exists with data applications. In such an environment, the rate control of the motion video becoms essential to satisfy its QoS.A new rate control method of MPEG-2 is proposed in our research project, and it is evaluated based on user's perception. The results show that the proposed mechanism can provide the motion video transfer with high-quality while keeping the required bandwidth to be small.In multimedia presentation, it is required that proper QoS control method should be specified along with each scene. However, it has not been sufficiently discussed how to deal with such specification. In this research project, we propose a new scenario description language for multimedia presentation, called "MSDL-II" which can specify QoS control method along with each scene. We also implement a distributed multimedia system as an executer of MSDL-II.

在这个研究项目中，我们在网络和终端系统中都建立了多媒体网络技术，多媒体应用可以利用它来保证服务质量。我们首先考虑了一种基于速率的拥塞控制的数据传输机制。ATM论坛最近对基于速率的拥塞控制算法进行了标准化。我们的研究是为了提出一种适合运动视频传输和数据应用共存的交通控制方法。在这样的环境下，运动视频的码率控制成为保证其服务质量的关键。本课题提出了一种新的基于用户感知的运动视频码率控制方法，并对该方法进行了评价。结果表明，该机制可以在保证较小带宽的前提下，提供高质量的运动视频传输；在多媒体播放中，需要根据不同的场景指定合适的服务质量控制方法。然而，如何处理这样的规范还没有得到充分的讨论。在本研究项目中，我们提出了一种新的用于多媒体呈现的场景描述语言MSDL-II，它可以根据每个场景指定服务质量控制方法。我们还实现了一个分布式多媒体系统作为MSDL-II的执行器。
