چکیده

Through detailed analysis of theoretical and real MPEG-compressed video streams, this paper addresses the task of extracting deterministic parameters from such sources in order to provide deterministic service guarantees. We propose and analyze the single-input single-output (SISO) algorithm with quality adjustment to compute the coherent parameters for the XGOP-B deterministic traffic model. Contrary to other proposals, the SISO algorithm leads to a single set of parameters for each input traffic and does not ask for external decisions to perform this stage. Moreover, the accuracy/complexity can be adjusted by a special variable. Our results show that the proposed approach leads to improved accuracy and that the complexity can be decreased by three orders of magnitude.

A self-extracting accurate modeling for bounded-delay video services

This article proposes the XGOP-B deterministic traffic model for MPEG video services requiring strict bounds on the quality of service provided by the network. The XGOP-B model takes advantage of two characteristics of MPEG video traffic by performing a two-level analysis of such sources. In our scheme, the traffic parameters are directly obtained by a single-input single-output parameter extra...

Identification of an Autonomous Underwater Vehicle Dynamic Using Extended Kalman Filter with ARMA Noise Model

In the procedure of designing an underwater vehicle or robot, its maneuverability and controllability must be simulated and tested, before the product is finalized for manufacturing. Since the hydrodynamic forces and moments highly affect the dynamic and maneuverability of the system, they must be estimated with a reasonable accuracy. In this study, hydrodynamic coefficients of an autonomous un...

A New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks

The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...

Extracting Deterministic Parameters from MPEG Video Sources with Quality Adjustment

The most stringent applications in the future will require network services with bounded-delay characteristics. In order to eeciently use the network resources, an accurate deterministic traac model must be developed. This paper analyses the XGOP-B model proposes an algorithm to extract parameters from MPEG video sources that does not allow unfortunate choices, since it automatically results in...

A Rate Control Algorithm for MPEG-2 to H.264 Real-time Transcoding

The demand of transcoding MPEG-2 to H.264 will be raised as the H.264 promises higher coding efficiency over previous video compression standards, while MEPG-2 has been widely adopted in many existing systems. This paper presents a rate control scheme for MPEG-2 to H.264 transcoder with the consideration of peak signal-to-noise ratio (PSNR) fluctuation control and re-quantized quality loss redu...
