The Digital Audio Broadcasting (DAB) system developed within the Eureka 147 project is well adapted to the requirements of broadcasting audio, programme associated data and general data including e.g. video, still images and coded traffic messages. The configuration of the DAB multiplex (i.e data rates and error protection of the different applications) is flexibly adjustable. Having evaluated ...

Innovations in hardware and network technologies lead to an exploding number of non-interrelated parallel media streams. Per se this does not mean any additional value for consumers. Broadcasting and advertisement industries have not yet found new formats to reach the individual user with their content. In this work we propose and describe a novel digital broadcasting framework, which allows fo...

A scalable source coder was designed for a hybrid HDTV terrestrial broadcasting system. The hybrid combination of analog and digital methods allows for both high video compression ratios and eecient utilization of the available channel capacity. EEcient channel utilization enables closer receivers to decode high quality video, and allows further receivers to decode natural looking, though lower...

Content distribution applications such as digital broadcasting, video-on-demand services, video conferencing, surveillance, and telesurgery are confronted with difficulties besides the inevitable compression and quality challenges with respect to intellectual property management, authenticity, privacy regulations, and access control. Meeting such security requirements in an end-to-end video dis...

Due to the extensive use of digital media applications, digital productions are easily copied and manipulated. Therefore, multimedia security and copyright protection is becoming important. Digital watermarking is an excellent tool to ensure security and protection of multimedia data by embedding some information into the digital production. For real time applications, such as Internet Protocol...

The increasing use of compression standards in broadcasting digital TV has raised the need for established criteria to measure perceived quality. This paper presents a methodology using Circular Back-Propagation (CBP) neural networks for the objective quality assessment of MPEG video streams. Objective features are continuously extracted from compressed video streams on a frame-byframe basis; t...
