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...
متن کاملSynthesis and characterization of mPEG-PCL copolymers as a polymersomes for delivery of enalapril as a model hydrophilic drug
Purpose: Enalapril maleate (EPM), was used for hypertension and congestive heart failure. In this way, an innovative delivery system with mPEG–PCL was synthesized and the release profile of the EPM from the drug-loaded polymersomes was evaluated. Methods: Di-block methoxy)-poly (ethylene glycol) - Poly (caprolactone) (mPEG-PCL) copolymers were synthesized and used to prepare of polymersom...
متن کاملA New Merit Version for Mpeg-2 Encoded Files a New Merit Version for Mpeg-2 Encoded Files a New Merit Version for Mpeg-2 Encoded Files 2 Merit 3.3 2.1 System Overview 2.3.1 Mpeg Bit Stream Parsing 2.3.2 Storing Mpeg Information
The MPEG Encoded Retrieval and Indexation Toolkit (MERIT) performs video segmen-tation of MPEG les in the compressed domain, using an algorithm based on macroblock type statistics. It was written in C by V. Kobla in 1995 for his doctoral work at the University of Maryland. Kobla's code dealt with MPEG-1 les only. In this report we update MERIT to analyze MPEG-2 les as well. We modify the le par...
متن کاملMPEG-4: An Object-Based Multimedia Coding Standard Supporting Mobile Applications
The ISO MPEG committee, after successful completion of the MPEG-1 and the MPEG-2 standards is currently working on MPEG-4, the third MPEG standard. Originally, MPEG-4 was conceived to be a standard for coding of limited complexity audio-visual scenes at very low bit-rates; however, in July 1994, its scope was expanded to include coding of scenes as a collection of individual audio-visual object...
متن کاملOn the Implementation of MPEG-4 Motion Compensation Using the TMS320C62x
This application report describes the implementation of MPEG-4 motion compensation on the Texas Instruments (TI) TMS320C62x digital signal processor (DSP). MPEG-4 is a standard for coding of audiovisual information being developed by the Motion Picture Experts Group (MPEG). MPEG-4 became an International Standard in December 1998. Motion compensation is a basic component of MPEG-4 and other vi...
