The paper deals with the utilization of Matlab for simulation and analysis of the digital image transmission and transmission distortions in DTV (Digital Television) and DVB (Digital Video Broadcasting) area. The simulation model that covers selected phenomena of DVB standard baseband signal processing applied in Matlab is presented and features of the protection against transmission errors are...

This White Paper provides an overview of major techniques used in DVB-T2 and their impact on service planning and operation of this new transmission technology.

This paper introduces the world’s first video and audio codec system that complies with 8K broadcasting standards and describes transmission experiments via a broadcasting satellite using this system. 8K Super Hi-Vision (8K) is a broadcasting system capable of highly realistic 8K Ultra High Definition Television (UHDTV) video and 22.2 multichannel audio. In Japan, domestic standards for 8K broa...

During their hospital stay in neonatal intensive care unit, newborn infants can be victims of several nosocomial infections. To improve the monitoring and prevention of such infections in this population, we developed the ASI-NOSO software solution which allows following up patients state regarding nosocomial infection during his hospital stay. Actually, the data's are recorded on the paper for...

Due to its advantages with respect to allowing simple receivers and flexibility, OFDM is – in addition to already existing systems such as DVB-T or HIPERLAN/2 – presently under consideration as auspicious candidate for future wireless communication air interface. However, despite many advantages, the lack of inherent diversity of pure OFDM based transmission schemes represents a major drawback....

OtaDigi is a DVB-T broadcast experiment run by the Helsinki University of Technology and other partners. This paper studies the behaviour of MHP applications, delivered through OtaDigi, using different broadcast configurations. The results show how under optimised configurations, broadcasters can use their bandwidth more efficiently and users can download the applications faster.

The contribution deals with the utilization of Matlab for simulation and analysis of digital QPSK and M-QAM modulators and demodulators used in DVB (Digital Video Broadcasting) standard. Presented modulators and demodulators are optional modules of simulation system that can evaluate the influence of transmission errors on transmitted digital signal and according visual information. The system ...

Error correction technology, with which the errors that occur during transmission are corrected, is essential when high-quality digital video and audio are to be provided in digital broadcasting The principle of error correction is that the improvement in the reliability of the received information as a result of error correction will more than compensate for the increase in data caused by the ...
