In case you haven’t noticed, multimedia communication over IP and wireless networks is exploding. Applications such as BitTorrent, used primarily for video downloads, now take up the lion’s share of all traffic on the Internet. Music file sharing, once on the legal cutting edge of massive copyright infringement on college campuses around the world, has moved into the mainstream with significant...

The increasing growth of sub-micron technology has resulted in the difficulty of testing. Design and test engineers have no choice but to accept new responsibilities that had been performed by groups of technicians in the previous year BIST is a design technique that allows a circuit to test itself. In this project, the test performance achieved with the implementation of BIST is proven to be a...

Digital signal processing (DSP) underpins modern wireless and wireline communications, medical diagnostic equipment, military systems, audio and video equipment, and countless other products, becoming increasingly common in consumers' lives. Due to advances in semiconductor technology, ever more complex DSP algorithms, protocols, and applications are now feasible, which, in turn, increase the c...

background: video-based instruction has been stated as an effective method of teaching and its potentials have encouraged instructors learners to opt this method purpose: the current study has compared the students' cognitive learning in the two approaches of lecture- based and video-based teaching. methods: this quasi-experimental study was conducted on 88 senior nursing students who were rand...

Within the EMBRACE project an advanced communications system and network was developed. It uses the DVB technology for the high-speed downlink and a novel multi-frequency TDMA system for the return link. The return link is scaleable to accommodate the variety of data rates. Emphasis was put on providing quality of service (QoS) in wireless IP networks. Site diversity is used to increase the ava...

The results of a transmission experiment of MPEG-2 coded video data over a satellite link affected by noise are presented. The goal was to investigate under which conditions this type of transmission is economically feasible. The scalability feature of the MPEG-2 encoder was used to produce different bitstreams of the same video sequence. We wanted to verify the best combinations among video an...

Handling and efficacy of a new video-optical intubation stylet were assessed in a simulated difficult tracheal intubation setting and compared with a conventional malleable stylet. Forty-five anaesthetists performed 10 tracheal intubations using both techniques. Laryngoscopy was performed by the observer, who created a grade 3 view according the classification by Cormack and Lehane. The time ta...

The importance of underwater video surveys as an exploration tool has been steadily increasing over recent years [1]. Better photographic equipment, more effective sources of illumination, and improved processing techniques all make video surveying a reliable tool for seafloor habitat mapping, sediment boundary delineation and groundtruthing, mapping and documentation of forensic and archaeolog...

A wireless image real-time transmission system is designed by using 3G wireless communication platform and ARM + DSP embedded system. In the environment of 3G networks, the embedded equipment has realized the functions of coding, acquisition, network transmission, decoding and playing. It is realized for realtime video of intelligent control and video compression, storage and playback in the 3G...

The geography of large and relatively underpopulated countries like Australia makes it attractive to use increasingly cheap information technology to improve access to general practitioners. People are already using the internet to access many other services. However, there are some moderating influences on the use of video-consultations in general practice. These include technical limitations,...
