The European Union IST research programme SAMBITS (System for Advanced Multimedia Broadcast and IT Services) project is using Digital Video Broadcasting (DVB), the DVB Multimedia Home Platform (MHP) standard, MPEG-4 and MPEG-7 in a studio production and multimedia terminal system to integrate broadcast data and Internet data. This involves using data delivery over multiple paths and the use of ...

Due to the recent popularization of digital broadcasting systems, selective contents, i.e., users watch their selected contents, have attracted great attention. For example, in a quiz program, a user selects his/her answer and watches the video content corresponding to the answer. Although a server can deliver content according to users’ preferences, the necessary bandwidth to play the content ...

The rollout of digital television systems is taking place in many countries worldwide. Utilizing the advantages of digital technologies, the special characteristics of mobile devices – such as small screen sizes and low power supplies – can be addressed, thus enabling mobile television and data services. IP Datacast (IPDC) based on Digital Video Broadcasting – Handhelds (DVB-H) is one of the te...

Orthogonal frequency division multiplexing (OFDM) is a special case of multicarrier transmission, where a single data stream is transmitted over a number of lower rate subcarriers. Orthogonal frequency division multiplexing (OFDM) has been chosen as modulation technique for different application wireless communications. OFDM can provide large data rates with sufficient robustness to radio chann...

AbstrAct The DVB Project is a European-based standards forum that for close to 15 years has been developing specifications for digital video broadcasting, many now implemented worldwide. Its IPR policy has several novel elements. These include " negative disclosure, " the obligation of each member to license IPRs essential to DVB specifications unless it gives notice of the unavailability of th...

Remote communities generally have limited access to telecommunications and broadcast media services. The development of terrestrial and satellite based digital TV delivery systems, particularly those using Digital Video Broadcast (DVB) standards, provide new opportunities for service delivery for remote communities. We investigate potential DVB based interactive TV, data and voice services for ...

With the growth of broadband networks, the Video-on-Demand (VoD) becomes realistic. Many significant broadcasting schemes are proposed to reduce the bandwidth requirements for stored popular videos, but they cannot be used to support live video broadcast perfectly. Herein, we propose a new broadcasting scheme, called Adaptive Live Broadcasting (ALB) scheme, which supports live video broadcastin...

In Europe, the end of the 20 century was the period of the changing to digital systems, including television broadcasting. In Hungary the first digital terrestrial pilot transmissions were started in 1999 and the supplier company plans a start of the full services in autumn 2004, so the time is right to give a brief technical description what is it about and why is it good for us.

We introduce a newsgathering system that features high mobility and wide-area coverage: Mobile Broadcasting Video (MBV) system. According to the original design concept, this system’s transmission channels provide increased mobility and wide area coverage, utilizing wireless LAN and low-orbit satellite technology. Also this system provides audiovisual quality that is comparable to current digit...
