Prediction of Cell Losses for VBR MPEG Encoders
نویسندگان
چکیده
In this paper modelling and queuing analysis of variable-bit-rate (VBR) MPEG coded video sources in B-ISDN networks based on ATM are studied. Modelling is performed by examining a low pass version of the aggregate MPEG sequence, capable of capturing the video activity. A discrete state continuous time Markov chain is then proposed to approximate the aggregate MPEG traffic. The previous model is used, combined with flow equivalent queuing analysis, to obtain analytical solution of cell losses. Experimental results are presented indicating that the proposed model is a good predictor of network resources.

Reliable Transmission of MPEG-2 VBR Video Streams over New Network Adaptation and ATM Adaptation Layers
This paper adresses the transmission of VBR MPEG-2 video streams on top of both Network Adaptation (NAL) and ATM Adaptation Layers (AAL) [1] for real-time multimedia applications. The NAL, speci c to MPEG-2, provides a selective data protection mechanism based on syntactic criteria. The AAL provides a reliable transmission by applying per-cell sequence numbering combined with a selective Forwar...
متن کاملEffects of cell loss on MPEG video: analytical modeling and empirical validation
MPEG-encoded variable bit rate (VBR) video traffic is expected to incur cell losses during its transmission over a broadband network. These cell losses introduce distortion into the received video. Frame drop rate and Root Mean Square Error (RMSE) can be used to objectively measure this distortion. These two metrics are useful in identifying the threshold cell loss rate (CLR) beyond which the q...
متن کاملbit - rate MPEG - 2 video compression
Most real-time MPEG-2 encoders are designed to perform in a constant-bit-rate (CBR) mode, in which buffer constraints are imposed to circumvent large deviations from a desired rate at any instant in time. Although such streams are generally good-quality sequences, certain types of operations or environments call for a more efficient real-time CBR encoder. The first part of the paper describes h...
متن کاملAccurate Prediction of Real - Time MPEG - 4 Variable Bit Rate Video Traffic
Kang Yong Lee et al. 823 ABSTRACT⎯In this letter, we propose a novel algorithm to predict MPEG-coded real-time variable bit rate (VBR) video traffic. From the frame size measurement, the algorithm extracts the statistical property of video traffic and utilizes it for the prediction of the next frame for I-, P-, and Bframes. The simulation results conducted with real-world MPEG-4 VBR video trace...
متن کاملPrediction of Variable Bit Rate Tra c Using Earthquake
In this paper, we use prediction algorithms to estimate the behavior of VBR video traac based on statistical short-term earthquake prediction methods. The probabilistic estimation of future inter-arrival times of peak values of MPEG-VBR video stream is considered in terms of Bayes theorem, and the Bayesian analysis of peak rate sample is evaluated on the basis of the proportion of successes rat...
