Towards an IP/GSE-Only Signalling Framework for DVB Transmission Systems
Towards an IP/GSE-Only Signalling Framework for DVB Transmission Systems Nimbe L. Ewald and Gorry Fairhurst Electronics Research Group, Department of Engineering, University of Aberdeen, AB24 3UE, UK {n.l.ewald,g.fairhurst}@abdn.ac.uk Abstract. An Internet Protocol/Generic Stream Encapsulation (IP/GSE) signal- ling framework is proposed to replace the current MPEG-2 Transport Stream (TS) Table-based signalling system and to enable smoother convergence of Digital Video Broadcasting (DVB) transmission systems and IP networks. GSE suitability is explained and a review of IP-based signalling techniques is pre- sented in order to select the optimal candidate methods for this architecture. Keywords: GSE, DVB, IP signalling, MPEG-2 TS Tables. 1 Introduction IP-based signalling procedures for content metadata currently take place in DVB networks, e.g. acquisition of an Electronic Service Guide (ESG) in a DVB-H system. However, the signalling for network metadata is still being performed through MPEG-2 encoded Tables conveyed by the TS even though the second generation of DVB systems can also support the Generic Stream (GS). The GS is expected to be used for IP-based services, where IP packets can be en- capsulated using the Generic Stream Encapsulation (GSE) protocol [1]&[2] as an adaptation layer that provides efficient IP packet encapsulation and fragmentation. In current network signalling, two sets of MPEG-2 encoded Tables are necessary for DVB system signalling, the Program Specific Information (PSI) and the System Information (SI) defined by MPEG and DVB, respectively. Tables are segmented in Sections, directly encapsulated in TS packets and sent with high repetition rates (e.g. -
Latest Transmitter Technology for VHF Band
Broadcasting and audio/video technology | Transmitter systems Latest transmitter technology for VHF band III Radio and television are celebrating a comeback in VHF band III as the UHF band is increasingly dedicated to other applications such as wireless communications. With the R&S®TMV9 medium-power transmitters and the R&S®THV9 high-power transmitters, network operators are now able to use the latest technology in this frequency band, too. Broadcasting in VHF band III is gaining new momentum Terrestrial broadcasting transmitters for UHF bands IV/V have somewhat overshad- owed transmitters for VHF band III over the past few years. That’s changing with the digital dividend, which has brought increased significance to band III for ana- log and digital TV as well as for digital audio broadcasting. This is because regula- tory authorities in many countries have instructed broadcast network operators to release frequencies in the UHF band so that they can be available for other appli- cations such as wireless communications. Free channels in VHF band III can be used for analog and digital TV. In addition, digital audio broadcasting in line with Fig. 1: Liquid-cooled R&S®THV9 high-power the DAB(+) standard will be implemented in this band. DAB(+) networks are being VHF transmitter featuring 5.2 kW output power expanded in some regions, while new, nationwide networks are being built in oth- from four amplifiers. ers. Broadcasting in VHF band III is gaining momentum. To accommodate this transition, Rohde & Schwarz has announced two new com- pact transmitter families that provide network operators with peak values in energy efficiency, power density and flexibility. -
NDS Response to Consultation on Issues Relating to Mobile TV Services
NDS Response to Consultation Paper on Issues Relating to Mobile TV Services Promoting a Level Playing Field NDS believes in and has consistently promoted a level playing field for all types of delivery platform in India – using cable, DTH satellite, IPTV, microwave distribution, powerline, terrestrial, wireless and yet to be developed technologies. NDS welcomes any regulatory development that will facilitate the growth of new free-to- air and pay TV services, provided that the regulatory development will not: • significantly impair the ability of content providers and platform operators to make reasonable returns on their investments, nor • significantly favour one type of service platform or delivery method over the others, or disfavour one compared to the others. NDS recognises that broadcast mobile TV is inherently a different type of service to the other broadcast TV services delivered to “fixed” devices, and that it is at a very early stage of deployment worldwide compared to such services. Broadcast mobile TV is still at a nascent stage, with at least ten delivery technologies1 and fewer than twenty commercially launched services to date. The technology fragmentation is thus far greater than that for either digital television broadcasting or 2G or 3G mobile telephony in their launch phases. Moreover, while DVB-H leads in terms of number of trials and services, the 1seg (ISDB-T), T-DMB and S-DMB technologies are way ahead of DVB-H in terms of usage, delivering mobile TV to over 11.7 million2, 6 million3 and 1.2 million users or subscribers respectively. It thus appears too early to pick winning technologies. -

ECC Report 177
ECC Report 177 Possibilities for Future Terrestrial Delivery of Audio Broadcasting Services April 2012 ECC REPORT 177 – Page 2 0 EXECUTIVE SUMMARY This Report considers the possibilities for continuing Radio Broadcasting into the future. While recognising that technological developments are opening a wide range of potential platforms for the distribution of audio content, it is felt that ‘terrestrial’ distribution with strategically placed transmitters simultaneously serving a large number of independent receivers will continue. This is particularly true for portable and mobile reception. With this in mind, this document concentrates on terrestrial distribution platforms and especially the relevant digital technologies that exist and are being developed. Radio is now very much a medium which can be, and is, accessed by an audience where a large portion is either mobile or doing something else. The motorist is a good example of this. The report looks at how this audience might be served in the future. While, in the past, conventional terrestrial radio broadcasting was the only viable way to serve this audience, technological convergence and changing habits mean that other platforms such as mobile broadband, satellites and wired infrastructures can now be used under the right circumstances. In spite of this, terrestrial broadcasting does offer certain advantages and it is felt that this will continue for the foreseeable future. Terrestrial broadcasting is itself changing with the advent of digital modulation systems. The report goes on to compare and contrast these modulation systems in some detail, looking at the strengths and weaknesses of each one. This is against the background considerations of audience size, geographical concentration and demographics, and how each system is able to exploit the available spectrum. -

Recommendations on Issues related to Digital Radio Broadcasting in India 1st February, 2018 Mahanagar Doorsanchar Bhawan Jawahar Lal Nehru Marg New Delhi-110002 Website: www.trai.gov.in i Contents INTRODUCTION ................................................................................................... 1 CHAPTER 2: Digital Radio Broadcasting Technologies and International Scenario .............................................................................................................. 5 CHAPTER 3: Issues Related to Digitization of FM Radio Broadcasting .............. 15 CHAPTER 4: Summary of Recommendations .................................................... 40 ii CHAPTER 1 INTRODUCTION 1.1 Radio remains an integral part of India‟s rich culture, social and economic landscape. Radio broadcasting1 is one of the most popular and affordable means for mass communication, largely owing to its wide coverage, low set up costs, terminal portability and affordability. 1.2 At present, analog terrestrial radio broadcast in India is carried out in Medium Wave (MW) (526–1606 KHz), Short Wave (SW) (6–22 MHz), and VHF-II (88–108 MHz) spectrum bands. VHF-II band is popularly known as FM band due to deployment of Frequency Modulation (FM) technology in this band. AIR - the public service broadcaster - has established 467 radio stations encompassing 662 radio transmitters, which include 140 MW, 48 SW, and 474 FM transmitters for providing radio broadcasting services2. It also provides overseas broadcasts services for its listeners across the world. 1.3 Until 2000, AIR was the sole radio broadcaster in the country. In the year 2000, looking at the changing market dynamics, the government took an initiative to open the FM radio broadcast for private sector participation. In Phase-I of FM Radio, the government auctioned 108 FM radio channels in 40 cities. Out of these, only 21 FM radio channels became operational and subsequently migrated to Phase-II in 2005. -
