A Generalized Linear Model for MPEG-2 Packet-Loss Visibility
نویسندگان
چکیده
In this paper, we focus on predicting the visibility of packet losses in MPEG-2 compressed video streams. We develop a generalized linear model (GLM) to predict the probability that a packet loss will be visible to an average viewer. The GLM input consists of parameters that can be easily extracted from the video near the location of the loss, and outputs an estimate of the probability that that loss is visible. We also show how our GLM can be used to classify each loss as visible or invisible. Using this method, we are able to achieve a high classification accuracy.

Design and Practical Implementation of a New Markov Model Predictive Controller for Variable Communication Packet Loss in Network Control Systems
The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...

The Networked Control System in modern control widely uses to decrease the implementation cost and increasing the performance. NCS in addition to its advantages is inevitable. Nevertheless they suffer of some limitations and deficiencies. Packet loss is one of the main limitations which affect the control system in different conditions and finally may lead to system instability. For this reason...
متن کاملPerceptual Video Quality Measurement Based on Generalized Priority Model
We consider factors not only in a packet, but also in its locality, to account for possible temporal and spatial masking effects. We apply our visibility model to packet priority for a video stream, when the network gets jam-packed at an in-between router; the router is able to choose which packets to drop such that visual quality of the video is minimally crashed. To show the effectiveness of ...
