Optimal Parallel MPEG Encoding
نویسندگان
چکیده
Moving Picture Expert Group (MPEG) encoding is a computationally expensive operation. This paper outlines a method of compressing video streams from within a Resolution Independent Video Language (RIVL) using the MPEG standard of compression in parallel. Two processes, a client and a server, work in tandem to parallelize the MPEG encoding process. The client dispatches jobs to each of the available servers for processing and the servers handle the compression of the video streams. The goal of Optimal Parallel MPEG Encoding is to derive a scalable, robust protocol to efficiently handle this computation.

Concurrency Analysis for Real Time MPEG-4 Video Encoding
The problem of scheduling MPEG-4 video objects for real-time encoding on to parallel architectures is studied. It is shown the need for the analysis of the MPEG-4 video encoder and the design of a scheduler that exploits the MPEG-4 concurrency. A real-time MPEG-4 scheme should take into account characteristics such as VOPs deadlines, precedence constraints, and encoding complexity issues. Concu...
متن کاملParallelizing MPEG Video Encoding using Multiprocessors
Many computer applications are currently using digital video. Recent advances in digital imaging and faster networking infrastructure made this technology very popular, not only for entertainment, but also in health and education applications. However, high quality video requires more storage space and communication bandwidth than traditional data. To deal with this problem, most of the digital...
متن کاملMotion Estimation in Mpeg-2 Video Encoding Using a Parallel Block Matching Algorithm
Motion estimation is the most computing-intensive component of the MPEG-2 encoding process. It refers to the action of searching for the closest prediction of a certain image block. The more accurate the prediction, the better achieved compression and quality are. The optimal solution is guaranteed by performing an exhaustive search for all possible predictions for a certain block. Such an appr...
متن کاملParallel algorithms for MPEG video compression with PVM
This paper presents parallel algorithms for MPEG video compression by using the PVM library. Because of the huge amount of computation, a sequential software encoder is slow at the coding of reasonably sized images (e.g. 0.1-0.3 frames per second). In order to speed up the process, we developed two kinds of parallel algorithm, which run on a cluster of workstations connected to the network. The...
متن کاملOperational rate-distortion optimal bit allocation between shape and texture for MPEG-4 video coding
MPEG-4 is the first multimedia standard that supports the decoupling of a video object into object shape and object texture information, which consequently brings up the optimal encoding problem for object-based video. In this paper, we present an operational rate-distortion optimal hit allocation scheme between shape and texture for MPEG-4 encoding. Our approach is based on the Lagrange multip...
