Recently, a Korean standard service, as the designated digital multimedia broadcasting (DMB) system, has been in commercial service following a period of time of careful reflection. Now, the next generation of digital broadcast services will not be limited to digital audio but also extended to a variety of multimedia data services as well as mobile application services. However, the current app...

This paper introduces the Terrestrial Digital Video Broadcasting DVB-T, stating its innovative aspects and its major advantages for data broadcasting, particularly TV broadcasting. It also presents the experimental DVB-T network built up by Retevisión in the framework of the Spanish VIDITER project (Terrestrial Digital Video) and the European ACTS VALIDATE (Verification and launch of Integrated...

Digital Video Terrestrial Broadcasting (DVB-T) allows combining broadcasting, telephone and data services in one network. It has facilitated mobile TV broadcasting. Mobile TV broadcasting is dominated by fragmentation of standards in use in different continents. In Asia T-DMB and ISDB-T are used while Europe uses mainly DVB-H and in USA it is MediaFLO. Issues of royalty for developers of these ...

Since it is easy to edit and perfectly produce a pirate copy, the copyright protection of digital object (e.g., audio, image and video) becomes an important concern. For example, the annual report by the Cable and Satellite Broadcasting Association of Asia (CASBAA),? which studied TV markets across 11 Asian countries, said the number of illegal connections is expected to have risen 20% to $5.2 ...

Interleaving along with error correction coding is an effective way to deal with different types of error in digital data communication. Error burst due to multipath fading and from other sources in a digital channel may be effectively combated by interleaving technique. In this paper an efficient technique to model convolutional interleaver using a hardware description language is proposed and...

The purpose of this article is to justify and recommend more fitting ways of measuring and controlling the audio level in digital broadcasting than looking at isolated samples or quasipeak levels. The new ITU-R BS.1770 standard, specifying long-term loudness and peak-level detection, is evaluated and a centre of gravity approach to loudness control is suggested. Metadata associated with Dolby A...

Orthogonal Frequency Division Multiplexing (OFDM) is known to exhibit robustness to multipath transmissions over time-invariant frequency selective channels, and this is among the main reasons it has been adopted as the standard modulation technique for both digital audio and video broadcasting in Europe. However by duality, OFDM is particularly sensitive to time-varying channels. In this paper...

The RDM-QIM algorithm has been proposed as a solution to the gain attack in QIM-based data hiding schemes. Several data hiding applications, such as broadcasting monitoring and live performance watermarking, requires a real-time multi-channel behavior. While Digital Signal Processors (DSP) have been used for implementing these schemes achieving real-time performance for audio signal processing,...

The Eureka-147 Digital Audio Broadcasting (DAB) standard defines the ’dynamic labels’ data field for holding information about the transmission content. However, this information does not follow a well-defined structure since it is designed to carry text for direct output to displays, for human interpretation. This poses a problem when machine interpretation of DAB content information is desire...
