SNR scalability, used in two-layer video coding, guarantees good base quality pictures at
the expense of increased overall bit-rate. By understanding the inherent inefficiencies of …

We describe the design and implementation of a self-manageable multi-tiered infrastructure
to support Web-based scientific simulations. This infrastructure demonstrates not only the …

In this paper a new multimedia caching strategy is proposed that includes several
optimizations to the state of the art. This algorithm takes its roots from the interval caching …

针对VBR 编码视频流传输时造成的资源需求的高可变性和资源利用的不平衡性,
提出一个新颖算法BSBS-VBR (buffer sharing and bandwidth smoothing of VBR streams) …

In order to obtain better video quality, media files are required to use variable-bit-rate (VBR)
encoding. However, it produces traffic burst and unbalanced resource utilizations to …

Summary Video-on-Reservation (VoR) serves as an attractive service providing
personalized multimedia services over the networks. In such multimedia services, clients …

Most of the existing buffer allocation and sharing schemes can not make full use of the
system resources while being implemented independently. Here, based on analysis of the …

Multimedia transmission is the effective way of transmitting multimedia elements (comprising
voice, audio, video, data etc) from one place to the other via internet enabled protocols and …
