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, video-on-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.

Abstract: The Association of Radio Industries and Businesses in Japan decided the specifications for a digital terrestrial broadcasting system called ISDB-T in 1998. The ISDB-T transmission system is recommended in ITU-R Recommendation BT.1306. Planning criteria of the ISDB-T system are recommended in ITU-R Recommendation BT.1368. This paper describes the transmission scheme of the ISDB-T system. First, it explains features of the ISDB-T system. Second, it describes transmission systems such as modulation, error correction, orthogonal frequency division multiplexing framing, transmission and multiplexing configuration control, guard interval, etc. Finally, it concludes discussion of the ISDB-T transmission system and describes transmission parameters used in Japan.

Abstract: In an RF communication system, aspects for cellular network and intelligent integrated broadcast television downlink with intelligent service control with feedback may comprise a mobile terminal (MT) generating a request for media comprising a specified quality of service (QoS) to be delivered to the mobile terminal. The request may be sent via a cellular service. The QoS may be negotiated between the MT and the cellular service and/or a broadcast service, where the cellular service and/or the broadcast service may provide the requested media. The specified QoS may be determined based on, for example, a received channel condition. The media may be received by the MT via a single integrated cellular and VHF/UHF baseband processor, and the received media may be consumed by the MT. The broadcast service may comprise, for example, a cellular broadcast service and VHF/UHF broadcast services such as, for example, DVB, ISDB, ISDB terrestrial, and ATSC services.

Abstract: Operators are introducing mobile television and digital video content services globally. The Handbook of Mobile Broadcasting addresses all aspects of these services, providing a comprehensive reference on DVB-H, DMB, ISDB-T, and MediaFLO. Featuring contributions from experts in the field, the text presents technical standards and distribution protocols, offering detailed coverage of video coding, including design methodology and error resilience techniques; state-of-the-art technologies such as signaling, optimization, implementation, and simulation; and applications of mobile broadcasting, including emerging areas and new interactive services.
