This paper describes a methodology to generate Transport Streams using low cost domestic equipment, in some experiments involving DVB (Digital Video Broadcasting). First the basic aspects of DVB are described followed by a short description of the equipment used to build the DVB TS generator. The results allowed building a TS generator which can be used for near full functional tests in DVB tec...

The analyze of MER (the modulation error) for the DVB-T (Digital Video Broadcasting Terrestrial) signal is studied in this article. The analyze of MER variation was made on the Romanian territory in two locations with and without obstacles. The results show that the DVB-T signal had a better quality and the DVB-T transmissions in the both locations are less affected by the noise. Key-Words: MER...

A novel technique for implementing statistical multiplexing (StatMux) of broadcast services over Digital Video Broadcasting for Handhelds (DVB-H) channels is proposed. DVB-H uses a time-sliced transmission scheme to reduce the power consumption used for radio reception part in DVB-H receivers. Due to the time-sliced transmission scheme, the implementation of known StatMux methods for DVB-H appl...

The 2012 World Radiocommunication Conference allocated the 694–790 MHz (700 MHz) band for the mobile service on a co-primary basis with other services in Region 1 (Europe, Africa, the Middle East). However, countries of Region 1 will also be able to continue the use of these frequencies for their digital terrestrial television services, if necessary. This allocation will be effective immediatel...

People travelling in public transportation vehicles are foreseen to be a relevant use case of future Digital Video Broadcast—Handhelds (DVB-H) systems. However, it is also one of the critical user cases, since, besides the vehicle penetration loss, the received signal quality is strongly affected by the high mobility of the users, which is accompanied by temporary shadowing and fast fading. On ...

This paper discusses in-house designed and developed scale-down DVB-RCS hub along with the performance of the realized hub. This development is intended to support the Satellite Based e-Learning initiative in India. The scale-down DVB-RCS HUB is implemented around a single PC with other subsystems making it very cost effective and unique of its kind. This realization will drastically reduce the...

This paper deals with the second part of the latest digital TV standard DVB-SH (Digital Video Broadcasting – Satellite to Handhelds) with focus on utilization of its advantages for the next generation of mobile TV broadcasting. In the second part the simulation model of DVB-SH-B, which is using satellite configuration with TDM (Time Division Multiplexing) transmission mode, is presented. The wo...

Ubiquitous, low power consumption and high bandwidth density communication will require passive athermal optical filters for WDM transceivers in Si-CMOS architecture. Two silicon-polymer composite structures, deposited using initiated chemical vapor deposition (iCVD), poly(perfluorodecyl acrylate) (pPFDA) and poly(perfluorodecyl acrylate-co-divinyl benzene) p(PFDA-co-DVB), are analyzed as candi...

A new system for hybrid satellite and terrestrial broadcasting of multimedia services to mobile handheld receivers has been recently standardised by DVB, namely DVB-SH. Direct mobile reception by S-band satellites is affected by obstacles (trees, buildings, bridges,..) blocking the Line-of-Sight (LoS) propagation, producing deep signal fading events lasting up-to several seconds or even more. T...

This paper presents an approach that enables the receiver to identify the DVB standard among different systems employing the OFDM technique (Orthogonal Frequency Division Multiplexing) consisting of large number of mutually orthogonal sub carriers. This characteristic provides high robustness against multi-path effects. The pilot induced cyclostationarity (PIC) approach is one of the new algori...
