Packet Media Streaming with Imprecise Rate Estimation

Packet Media Streaming with Imprecise Rate Estimation

We address the problem of delay-constrained streaming ofmultimedia packets over dynamic bandwidth channels. Efficient streaming solutions generally rely on the knowledge of the channel bandwidth, in order to select the media packets to be transmitted, according to their sending time. However, the streaming server usually cannot have a perfect knowledge of the channel bandwidth, and important pa...

Rate-distortion Optimized Packet Scheduling and Routing for Media Streaming with Path Diversity

We consider diversity for media streaming in a rate-distortion optimization framework. A sender-driven transmission scenario is investigated, where diversity is achieved by using multiple transmission paths over the network. The proposed framework enables the sender to decide at every instant which packets, if any, to transmit and over which transmission paths in order to meet a rate constraint...

Scalable On-Demand Media Streaming with Packet Loss Recovery

Efficient rate distortion optimized media streaming

This thesis considers the problem of finding optimal transmission strategies in ratedistortion optimized media streaming over a packet erasure channel with random delay. A compressed media stream, such as an audio or video stream, that is split into a set of usually interdependent data units, is to be sent to a receiver for instant playback. The data unit dependencies are modeled as a directed ...

Streaming Media in Variable Bit-rate Environments

We consider streaming of video sequences over both, constant and variable bitrate (VBR) channels. Our goal is to enable decoding of each video unit before exceeding its displaying deadline and, hence, to guarantee successful sequence presentation even if the media rate does not match the channel rate. In this work, we will show that the separation between a delay jitter buffer and a decoder buf...
