Terrestrial DVB (DVB-T): A Broadcast Technology for Stationary Portable and Mobile Use (original) (raw)

Review: Digital Video Broadcasting Terrestrial (DVB-T) and DVB-T2

Digital video broadcasting Terrestrial (DVB-T) is a leading international standard established for the move from Analog to digital broadcasting basically via terrestrial networks. Within DVB-T it is possible to carry defined data containers in addition to the audio and video in the MPEG 2 transport stream.Digital broadcast systems have increasingly been deployed for various services such as Digital Video Broadcasting (i.e. DVB-S, DVB-T, etc.) and Digital Audio Broadcasting (DAB). Classical digital broadcast systems were designed with fixed modulation techniques, which had to guarantee reliable communication even with very hostile channel environment. Video Broadcasting is playing a key role in communication areas. In this paper DVB-T (terrestrial based digital video broadcasting) and DVB-T2 is analyzed in terms of various parameters.

DVB-T2: The Second Generation of Terrestrial Digital Video Broadcasting System

IEEE Transactions on Broadcasting, 2000

This paper provides a review of the second generation of Terrestrial Digital Video Broadcasting standard DVB-T2. DVB-T2 is the evolution of DVB-T and, together with DVB-S2 and DVB-C2, inaugurated a new transition from the first generation digital broadcasting systems, similar to the transition from analog to digital systems. In the paper the most relevant features of DVB-T2 are explained in detail, along with their benefits and trade-offs.

HDTV field trials using DVB-T and DVB-T2 broadcasting systems

2010

This paper presents the first field trials carried out in Spain to test HDTV reception using DVB-T and DVB-T2 systems. High definition and standard definition digital television contents and services were multiplexed and broadcasted from a terrestrial transmitter. The aim of these trials was to analyze DVB-T2 technology when this system is configured according to the needs of terrestrial HDTV broadcasting and to compare the results with DVB-T technology in terms of CNR requirements and achieved data rate. Field measurements were carried out in different scenarios and reception conditions. The study presented in this paper is focused on fixed reception, Gaussian channel, because it is the expected reception condition for HDTV.

DVB-The Family of International Standards for Digital Video Broadcasting

Proceedings of the IEEE, 2006

This paper presents an overview of the fields of technology addressed by technical specifications created by the DVB Project (DVB). It serves as an introduction to the section of the special issue of the PROCEEDINGS OF THE IEEE in which a number of very recent DVB technologies will be explained in detail. The overview starts with an explanation of the wide field of application which the members of the DVB Project decided to address over the years. It then discusses the base band processing required for DVB services and looks into the specifications provided for the broadcasting over cable, satellite, and terrestrial transmitters. The concept of broadcasting generic data is explained and the interaction channels supported by DVB will be introduced. Multimedia Home Platform (MHP) facilitates a horizontal market of receivers able to run software programs (applications in DVB terminology) in a well defined way. After a short introduction into the specifications addressing the delivery of broadcast-type content over broad-band IP networks, the concept of broadcasting to handheld devices is introduced. The paper closes with a description of the newest areas of development DVB has decided to tackle.

DVB-NGH: The Next Generation of Digital Broadcast Services to Handheld Devices

IEEE Transactions on Broadcasting, 2014

This paper reviews the main technical solutions adopted by the next generation mobile broadcasting standard DVB-NGH, the handheld evolution of the second generation digital terrestrial TV standard DVB-T2. The main new technical elements introduced with respect to DVB-T2 are: layered video coding with multiple physical layer pipes, time-frequency slicing, full support of an IP transport layer with a dedicated protocol stack, header compression mechanisms for both IP and MPEG-2 TS packets, new LDPC coding rates for the data path (down to 1/5), non-uniform constellations for 64QAM and 256QAM, fourdimensional rotated constellations for QPSK, improved time interleaving in terms of zapping time, end-to-end latency and memory consumption, improved physical layer signaling in terms of robustness, capacity and overhead, a novel distributed MISO transmit diversity scheme for SFNs, and efficient provisioning of local content in SFNs. All these technological solutions, together with the high performance of DVB-T2, make DVB-NGH a real next-generation mobile multimedia broadcasting technology. In fact, DVB-NGH can be regarded the first third-generation broadcasting system because it allows for the possibility of using multiple input multiple output MIMO antenna schemes to overcome the Shannon limit of single antenna wireless communications. Furthermore, DVB-NGH also allows the deployment of an optional satellite component forming a hybrid terrestrial-satellite network topology to improve the coverage in rural areas where the installation of terrestrial networks could be uneconomical.

Mobility issues in a DVB-T environment

Digital Video Broadcasting (DVB) is the leading technology for permitting digital television access to a wide repartition of users. There exist many different types of DVB technologies: DVB-T for Terrestrial, DVB-S for Satellite, DVB-C for Cable, each one with its own specifications. This paper focuses on the DVB-T mechanism and the way it handles mobility; it describes all the mobility issues and challenges arising from this technology. Investigations on the integration of the Internet Protocol, IP, over the coming terrestrial digital television standard, DVB-T, are also included. It presents mobility scenarios in a special DVB-T environment, along with a complete broadcasting architecture, in which all leading mobile technologies coexist, and provides solutions and enhancements for a better technology deployment.

Analysis and Performance Comparison of DVB-T and DTMB Systems for Terrestrial Digital TV

Computing Research Repository, 2008

Orthogonal frequency-division multiplexing (OFDM) is the most popular transmission technology in digital terrestrial broadcasting (DTTB), adopted by many DTTB standards. In this paper, the bit error rate (BER) performance of two DTTB systems, namely cyclic prefix OFDM (CP-OFDM) based DVB-T and time domain synchronous OFDM (TDS-OFDM) based DTMB, is evaluated in different channel conditions. Spectrum utilization and power efficiency are

DVB-T2: An outline of HDTV and UHDTV programmes broadcasting

Telfor Journal, 2015

Increasing of video resolution of the HD programmes requires a higher bit rate. On the other hand, a continuous enhancement of existing and introduction of new source coding techniques are evident. Technical evolution of the Digital Terrestrial Television platform improves channel coding and RF channel utilization. Some optional solutions have also been proposed. This paper discusses the possibilities of allocating HD programmes in formats expected in the near future. Performed calculations are guidance to accurate examination of the efficiency of allocating high definition programmes in the DVB-T2 multiplex, in line with existing and expected enhancements.
