women constitute about half population of the society and public opinions have caused women not to act and progress well in the society. television as the most popular and further epidemic media may present the women's abilities toward achieving the goals of twenty-year vision deed. the present essay is attempting to consider the different abilities of women such as personal, familial and ...

aim: the aim of this study is to identify a framework of needed expertise for publishing academic electronic textbooks according to the characteristics of this kind of books. therefore the final result focuses on needed experts through the consensus method. method: delphi technique using the researcher made questionnaire was done in four rounds. the research population was composed of forty exp...

The MPEG-4 standardization phase has the mandate to develop algorithms for audio-visual coding allowing for interactivity, high compression, and/or universal accessibility and portability of audio and video content. In addition to the conventional “frame”-based functionalities of the MPEG-1 and MPEG-2 standards, the MPEG-4 video coding algorithm will also support access and manipulation of “obj...

This memo describes a packetization scheme for MPEG video and audio streams. The scheme proposed can be used to transport such a video or audio flow over the transport protocols supported by RTP. Two approaches are described. The first is designed to support maximum interoperability with MPEG System environments. The second is designed to provide maximum compatibility with other RTP-encapsulate...

Recently, a new approach in low bitrate coding of stereo and multi-channel audio has emerged: Spatial audio coding permits an efficient representation of multi-channel audio signals by transmitting a downmix signal along with some compact spatial side information describing the most salient properties of the multi-channel sound image. Besides its impressive efficiency allowing multi-channel sou...

BBC R&D has been conducting audio tests for and on behalf of ISO/IEC MPEG since 1973. This report summarises the more important of those tests and the methods used for the assessments. Systems tested include MPEG-2 Layers II and III, as well as the more recent Non-Backwards Compatible codecs. It is reported that the optimisation is still in progress. No part of this publication may be reproduce...

BACKGROUND Rapid identification of subject experts for medical topics helps in improving the implementation of discoveries by speeding the time to market drugs and aiding in clinical trial recruitment, etc. Identifying such people who influence opinion through social network analysis is gaining prominence. In this work, we explore how to combine named entity recognition from unstructured news a...

For the acceptance of future network-based media services the technical advancement of the man-machine interface is of great importance. The Fraunhofer Institute for Systems and Innovation Research (ISI) in Karlsruhe has conducted an expert survey on different acceptance factors, on the future development of media usage behavior, on network infrastructure and terminal devices as well as on the ...

MPEG Audio Layer-3, or “MP3,” has rapidly become the most popular format for the encoding and compression of digital audio and has found widespread application in both hardware and software. This literature survey provides a brief introduction to the MPEG (Moving Picture Experts Group) standard for audio encoding and explores the feasibility of formally modeling an encoder and a decoder. It als...

In this paper we present a novel way of creating mosaics from an MPEG video sequence. Two original aspects of our work are that (1) we explicitly compute camera motion between frames and (2) we deduce the camera motion directly from the motion vectors encoded in the MPEG video stream. This enables us to create mosaics more simply and quickly than with other methods. Abstract In this paper we pr...
