Towards 5G Broadcast

Large-scale TV transmission is being tested in the Bavarian research project 5G TODAY using the latest technologies. Based on the 5G broadcast mode FeMBMS it will be possible to broadcast media content for 5G terminals via high power high tower (HPHT) transmitters in the future.

Bayerischer Rundfunk

Bayerischer Rundfunk, or BR for short, is Bavaria’s public service broadcaster, reaching around eight million people throughout Germany every day. With ten radio stations and two television channels, two internationally renowned symphony orchestras, a celebrated chorus and more than five thousand members of staff, we are one of Europe’s most respected broadcast institutions. BR operates broadcasting centres in Munich and Nuremberg, as well as over 20 studios and its own broadcasting networks throughout Bavaria. As the fourth largest member of ARD, BR delivers many high-quality programmes to Das Erste, ARTE, 3sat, phoenix and KiKA. Included among the highlights are feature films, series, documentaries and sports broadcasts. ARD consists of nine regional broadcasters and the Deutsche Welle.

Within 5G TODAY, BR provides the necessary broadcast infrastructure. At two locations, high power FeMBMS transmitters will be installed. The transmitters are operated in a single frequency network via channel 56 (750-758 MHz). TV-content to be transmitted is also applied by BR. The main purpose of the project is to investigate the usability of 5G for the terrestrial transmission of broadcast signals. Furthermore it is of interest for the BR which opportunities 5G offers for its content, especially video content and production.

Telefónica

Telefónica

Telefónica Deutschland offers telecommunications services for private and business customers, as well as innovative digital products and services in the fields of the Internet of Things and data analytics. With a total of 49,4 million customer connections (as of 30 June 2018), the company is one of the leading integrated telecommunications providers in Germany. In the mobile segment alone, Telefónica Deutschland is responsible for more than 45,2 million connections – no other domestic network operator connects more people. By 2022, the company aims to become the “Mobile Customer & Digital Champion”, meaning the preferred partner for costumers in the German mobile service market that allows them mobile freedom in the digital world. Through its core brand O2 and various secondary and partner brands, the company sells postpaid and prepaid mobile telecommunications products including innovative mobile data services. The basis for this is a mobile service network based on a high-performance GSM, UMTS and LTE infrastructure. Telefónica Deutschland also provides telephony and high-speed internet products, such as VDSL, in the fixed network field. Telefónica Deutschland Holding AG has been listed in the Prime Standard on the Frankfurt Stock Exchange (TecDAX) since 2012. In the 2017 financial year, the company generated revenue of EUR 4,3 billion with almost 9,300 employees. The company is majority owned by the Spanish telecommunications group Telefónica S.A., headquartered in Madrid. With the presence in 21 countries and a customer base of almost 350 million connections, the group is one of the world’s biggest telecommunications providers.

Telefónica Deutschland is mainly supporting the project “5G TODAY” with its 700 MHz frequencies. Therefore focusing on two primarly topics, the experience how large cells in 5G can be used in the future and understanding the needs for 5G TV.

Rohde & Schwarz

Rohde & Schwarz

Rohde & Schwarz has been an innovator in broadcast and media for over 70 years. The Rohde & Schwarz product portfolio covers the entire signal processing chain for digital video and audio content – from ingest and playout to encoding and multiplexing, from contribution to satellite and IP networks to streaming and broadcast services and entire broadcast networks. The T&M expert also offers a development, production and quality assurance. Rohde & Schwarz invests in an IP and software based future built with the blend of innovation, experience and stability that the company can offer.

As part of the project 5G TODAY, Rohde & Schwarz is developing the FeMBMS standard defined in 3GPP release 14, using its R&S THU9evo high-power transmitter as basis. In addition, Rohde & Schwarz is responsible for the complete modulation feed for broadcasting TV programs of the Bavarian Broadcasting Corporation via FeMBMS. The R&S AVHE100 encoding and multiplexing solution is being used for this purpose, as well as a prototype MBMS gateway that encapsulates the audio/video data into the EPC protocol and delivers the SFN time information.

Institut für Rundfunktechnik (IRT)

Institut für Rundfunktechnik (IRT)

IRT is the research and innovation center for audiovisual technologies of the public broadcasters ARD, ZDF, Deutschlandradio, ORF and SRG/SSR. IRT explores, observes and develops new technologies with the aim to strategically adapt broadcasting to new market environments and needs. Around 100 employees do research on the premise in Munich in close cooperation with partners and clients for innovative solutions in the research areas of new audio-visual formats, cross-media technologies, metadata, cloud production, all IP/IT, smart data, security, multi-platform, 5G, frequencies and regulation and IP distribution.

THE IRT is the proposer and the scientific partner in the 5G TODAY project. As a research and development institute of the public service broadcaster, the IRT has a great deal of knowledge in the field of terrestrial broadcasting systems such as DVB-T2 and DAB+ and has been dealing with mobile standards such as UMTS and LTE/5G. The IRT makes an important contribution to the verification of the FeMBMS specification for the broadcasting service. The main task of the IRT in the project 5G TODAY is the prototype development of the FeMBMS receiver based on Software Defined Radio (SDR). The IRT has also been working on radio network planning and propagation models for terrestrial broadcasting for decades. The coverage prediction for the FeMBMS test field has been already calculated by IRT’s frequency planning tool Fransy. The IRT will carry out field measurements together with the project partners to validate the coverage prediction and participate in the results analysis and utilization planning.
