Scalable Media Object Framework of MPEG-2 Video for QoS Adaptation
Hyeong-Cheol Kim, Chan-Geun Jeong · The Transactions of the Korea Information Processing Society · 1999
In this paper, we propose a new framework for scalable media object to adapt the various QoS requirements in the heterogeneous networking environment. An MPEG-2 video is split into a set of scalable media objects in terms of temporal scaling and fidelity scaling. The portion of the scalable media objects is selectively delivered to adapt the QoS requirement. This framework can satisfy the various QoS requirements on bandwidth, even though the clients share a multipoint channel. By analysis on the rate-distortion characteristics of scalable media object framework, we shows our approach is feasible to support the various QoS requirements.
