“…Japan began digital broadcasting using a communication satellite (CS) on the geostationary orbit of 128 • east longitude (CS 128 • E) with DVB-S standard. Now, digital broadcasting with broadcasting satellite (BS) and CS on the geostationary orbit of 110 • east longitude (BS/CS 110 • E) is using ISDB-S standard [37]. Compared with DVB-S, ISDB-S adopts the Trellis coded 8-phase shift keying modulation, enabling the broadcasting of two high-quality programs with one transponder.…”

Integrated ServicesDigital Broadcasting-Terrestrial/Satellite (ISDB-T/S) signal, used in Japan as the digital television (TV) broadcasting standard, is exploited in this paper for passive bistatic radar two-dimensional imaging of stationary targets. A multifunctional system is developed with commercial-off-the-shelf antennas, low-noise block downconverters, and amplifiers. Several practical issues of using ISDB-T/S signals for imaging are high-lighted. Ambiguity function analysis, accurate time delay estimation, inverse filtering, and local frequency correction are carried out. Multiple TV channels are combined to improve the range resolution. In order to reduce the artifacts caused by the frequency gaps among multiple TV channels, two low-rank matrixcompletion-based algorithms are proposed. Experiment results with different targets validate the performance of the designed system and the proposed algorithms. Keywords-Integrated services digital broadcasting, low-rank matrix completion (MC), passive bistatic radar (PBR), twodimensional (2-D) imaging. I. INTRODUCTION N OWADAYS, broadcasting signal, communication signal, and navigation signal are used for passive bistatic radar (PBR) applications with an increasing interest [1]-[3]. By using existing noncooperative illuminators without a dedicated radar transmitter, PBR can achieve several attractive advantages over active radar: smaller vulnerability, no need for frequency allocations, and lower cost. Various signals, such as FM radio, GSM, DAB, Digital Video Broadcasting (DVB-T/S), and Wi-Fi, have been researched to validate their performances for different applications: moving target range-Doppler mapping, synthetic aperture radar (SAR) imaging, inverse SAR (ISAR) imaging, through the wall target detection, direction finding, displacement estimation, and coherent change detection [4]-[10]. For passive radar, frequency bandwidth is one of the important considered

Abstract-This paper is a survey of the transmission techniques used in digital television (TV) standards worldwide. With the increase in the demand for High-Definition (HD) TV, videoon-demand and mobile TV services, there was a real need for more bandwidth-efficient, flawless and crisp video quality, which motivated the migration from analogue to digital broadcasting. In this paper we present a brief history of the development of TV and then we survey the transmission technology used in different digital terrestrial, satellite, cable and mobile TV standards in different parts of the world. First, we present the Digital Video Broadcasting standards developed in Europe for terrestrial (DVB-T/T2), for satellite (DVB-S/S2), for cable (DVB-C) and for hand-held transmission (DVB-H). We then describe the Advanced Television System Committee standards developed in the USA both for terrestrial (ATSC) and for hand-held transmission (ATSC-M/H). We continue by describing the Integrated Services Digital Broadcasting standards developed in Japan for Terrestrial (ISDB-T) and Satellite (ISDB-S) transmission and then present the International System for Digital Television (ISDTV), which was developed in Brazil by adopteding the ISDB-T physical layer architecture. Following the ISDTV, we describe the Digital Terrestrial television Multimedia Broadcast (DTMB) standard developed in China. Finally, as a design example, we highlight the physical layer implementation of the DVB-T2 standard.

A new mobile multimedia broadcasting service using a geostationary satellite was launched on May 2005 in Korea. The Satellite Digital Multimedia Broadcasting (S-DMB) system provides high quality audio, video and data broadcasting services to handheld and mobile receivers. S-DMB is a personal digital media which can provide bidirectional and interactive services via the convergent platform of broadcasting and communication. At present, TU Media, the only S-DMB service provider in Korea, provides 15 TV channels, 19 audio channels, and 3 data channels. The number of subscribers is about 890,000 by Nov. 2006. Thousands of low power gap fillers (repeaters) have been installed in the shadowed or blocked reception areas in the metropolitan Seoul.This paper presents the system requirements, standards and specifications, architecture, and service status of S-DMB in Korea. Comparisons with other satellite broadcasting systems and the services are also presented. Link budget analysis on the direct path down-link (satellite to receivers) and relay path feeder link (gap fillers to receivers) are carried out in order to ensure the satisfactory QoS.
