Transcoding is an important technique for reducing the bit rate or spatial resolution to meet the constrained transmission bandwidths and terminal capabilities. In this paper, we propose a spatial downscaling transcoding method to convert an MPEG-2 bitstream into an H.264/AVC bitstream. A novel feature of the proposed method is to focus on the fast mode decision that fully exploits the advantag...

Traditional transcoding on multimedia has been performed from the perspectives of user terminal capabilities such as display sizes and decoding processing power, and network resources such as available network bandwidth and quality of services (QoS) etc. The adaptation (or transcoding) of multimedia contents to given such constraints has been made by frame dropping and resizing of audiovisual, ...

Multimedia is gaining ever more importance on the Internet. This increases the need for intelligent and efficient video caches. A promising approach to improve caching efficiency is to adapt videos. With the availability of MPEG-4 it is possible to develop a standard compliant proxy cache that allows fast and efficient adaptation. We propose a modular design for an adaptive MPEG-4 video proxy t...

Fused filament fabrication (FFF) has numerous process parameters that influence the mechanical strength of parts. Hence, many optimization studies are performed using conventional tools and algorithms. Although have also been advanced algorithms, limited research reported in which variants naked mole-rat algorithm (NMRA) implemented for solving issues manufacturing processes. This study was to ...

Drawing on a contingency perspective of the resource-based view firm, we test thesis that relationship between international entrepreneurial orientation (IEO) and performance export-manufacturing firms is context-sensitive contingent innovation capabilities. Using time-lagged survey data from 369 Bangladeshi in least developed country (LDC) as an extreme empirical context, predict process produ...

Information systems (IS) development is becoming increasingly more geographically dispersed. Although process rigor, process standardization, and process agility are generally believed to have a positive impact on software development, it has not been well understood how these process capabilities affect distributed IS development. More important, no prior research has investigated their intera...
