First, we develop a model for streaming VBR{encoded continuous m...

Interactive Video Streaming with Proxy Servers

Video Streaming across Best-Effort Wide-Area Networks with Controlled Quality Assurance Using Proxy Servers

Video Streaming with Interactive Pan/Tilt/Zoom

High-spatial-resolution videos offer the possibility of viewing an arbitrary region-of-interest (RoI) interactively. The user can pan/tilt/zoomwhile watching the video. This chapter presents spatial-random-access-enabled video compression that encodes the content such that arbitrary RoIs corresponding to different zoom factors can be extracted from the compressed bit-stream. The chapter also co...

Multimedia Proxy Caching for Video Streaming Applications

This paper deals with the use of proxy servers to cache streaming video objects. In this paper, we describe a streaming architecture for layered video objects that uses the concept of layered caching. A new replacement policy is proposed, which is based on the playout time of a video object at the client. We define a new quality metric that takes the number of layers as well as the importance o...
