Rate-distortion optimized frame dropping and scheduling for multi-user conversational and streaming video

We propose a Rate-Distortion (RD) optimized strategy for frame-dropping and scheduling of multi-user conversational and streaming videos. We consider a scenario where conversational and streaming videos share the forwarding resources at a network node. Two buffers are setup on the node to temporarily store the packets for these two types of video applications. For streaming video, a big buffer ...

Rate-distortion Optimized Video Frame Dropping on Active Network Nodes

We propose a rate-distortion optimized video frame dropping strategy that can be applied on active network nodes in case of heavy traffic load. Our approach relies on side information that is sent along with the video bit-streams. The side information consists of a rate vector containing the frame size (in bytes) of every picture as well as a distortion matrix describing the reconstruction dist...

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 ...

Techniques for Improved Rate-Distortion Optimized Video Streaming

We present techniques recently developed by our research group at Stanford University to improve the performance of existing algorithms for rate-distortion optimized video streaming. In rate-distortion optimized streaming, media packet transmissions are controlled in a way that gives an optimal tradeoff between the expected bit-rate that will be required for the transmissions and the expected m...

Rate-distortion optimized frame type selection for MPEG encoding

In this paper, we present an algorithm for joint optimization of anchor frame separation and bit allocation for motion-compensated video coders. The anchor frame separation is optimized in the sense that the distortion is minimized under a bit budget constraint. At the same time, the quantization for each frame in a group of pictures is also optimized in an operational rate distortion sense. Th...
