Content-based video retrieval has been a very efficient technique with new video content, but it has not regarded the increasingly dynamic interactions between users and content. We present a comprehensive survey on user-based techniques and instrumentation for social video retrieval researchers. Community-based approaches suggest there is much to learn about an unstructured video just by analy...

the video quality assessment must be adapted to the human visual system, which is why researchers have performed subjective viewing experiments in order to obtain the conditions of encoding of video systems to provide the best quality to the user. the objective of this study is to assess the video quality using image features extraction without using reference video. rmse values and processing ...

Video encryption is becoming increasingly important as multimedia applications gain more and more popularity. With a focus on the widely-used H.264 video coding standard, various encryption algorithms based on the intra prediction mode have been developed while suffering limited scrambling space and inadequate security. In this paper, the existing encryption algorithms are first analyzed with r...

In the recent few years, the IPTV service has been widely implemented and actively studied. Among the various IPTV services, the Video-on-demand (VoD) service, which offers watching a selected video at any time through a dedicated stream, is taking the major service portion and being increasingly deployed to the market. Currently, most of the VoD server is transmitting the videos by dedicated u...

Mobile Ad hoc NETworks (MANETs) are becoming more essential to wireless communications due to growing popularity of mobile devices. However, MANETs do not seem to effectively support multimedia applications and especially video transmission. In this work, we propose a cross-layer design that aims to improve the performance of video transmission using TCP Friendly Rate Control (TFRC). Our design...

As computer and network technology advance, multimedia data can be transferred in real time on the internet. The increasing user demands for various multimedia data make VoD (video on demand) services to be developed. Video on demand (VoD) services are being used in lots of fields such as entertainment, distant learning, home shopping, and interactive news. Video-on-Demand (VoD) has been gainin...

This paper will investigate a variety of alternate controllers that are making an impact in interactive entertainment, particularly in the video game industry. Since the late 1990’s, the surging popularity of rhythmic and musical performance games in Japanese arcades has led to the development of new interfaces and alternate controllers for the consumer market worldwide. Rhythm action games suc...
