Fraunhofer DRM ContentServerTM R4 04 / 2009 Fraunhofer DRM ContentServerTM R4 The Fraunhofer DRM ContentServerTM R4 is a highly reliable professional broadcast system for Digital Radio Mondiale (“DRM“, see www.drm.org). It provides all options DRM offers and all interfaces for a smooth integration into the broadcast chain. The Fraunhofer DRM ContentServerTM R4 provides triple functionality: – DRM AudioServer with multistream real-time audio encoding – DRM Multimedia DataServer supporting all standarized as well as broadcaster specific data services, covering import, processing, encoding and broadcast Fraunhofer DRM AudioServer This system component provides realtime encoding of up to four audio streams in parallel: – Live analog, digital, Livewire or MP3 playlist input – AAC (mono/stereo/parametric stereo), HVXC and CELP encoding with SBR – All possible bitrates including UEP (unequal error protection) – All available sampling rates (8 / 12 / 16 / 24/ 48 kHz) – MPEG Surround option Versatile data import interfaces and automation features allow for a smooth integration into production environments: – RSS import (automatically scheduled or manually triggered) – Ftp, ftp-mirroring and http-mirroring – Web-interface for quick data editing using a standard web browser – UECP, Funkhaustelegramm, Leitungsprotokoll and ZENON studio interfaces – Socket interface for real-time data insertion – Protected connections for secure and reliable data import restricted to the predefined data sources: ftps, ftps-mirroring, https-mirroring Fraunhofer Multimedia DataServer – DRM Multiplex Generator managing the extensive DRM signalling capabilities, generating the full digital DRM Multiplex and providing standard MDI/DCP output streams This component supports the import / collecting, merging, checking, conversion and encoding of data for all stand ardized DRM / DAB as well as individual data applications. DRM / DAB data applications: Fraunhofer DRM Multiplex Generator – – – – – – All DRM signalling features are supported according to ETSI ES 201 980 (v.3.1.1) including the DRM dynamic reconfiguration feature. The One-box DRM Broadcast Solution The system is typically located in the studio, at a playout center or at the transmitter site – with full remote control for administration and data provision. The remote web interface featuring Fraunhofer´s in-place-editing techno logy for quick and convenient system configuration can be accessed through any modern web browser. The output signal of the Fraunhofer DRM ContentServerTM R4 carries the complete DRM Multiplex (FAC, SDC, MSC) in MDI/DCP format according to ETSI TS 102 820 (Multiplex Distribution Interface) and ETSI TS 102 821 (Distribution and Communications Protocol). This DRM Multiplex can be fed simultaneously to any number of DRM Modulators (optional SFN operation) and monitoring stations. The protocol standard MOT 2.1.1 (Multimedia Object Transfer) for enhanced file and directory structure transmissions is supported. DRM TextMessages Journaline® MOT Slideshow MOT Broadcast Website TPEG Traffic Information PRBS – internally generated synchronous or asynchronous test patterns – EPG – Electronic Programme Guide – TMC – Traffic Message Channel Open interfaces allow the transmission of any custom-tailored individual application at various protocol levels: – Transparent File Transmission via MOT – IP Insertion – (Internet Protocol tunneling) – TDC – Transparent Data Channel – DRM Data Units – MSC Data Groups – Synchronous / asynchronous data streams Transmission channel options: – Robustness modes A, B, C, D – Spectrum occupancy 4.5, 5, 9, 10, 18, 20 kHz – MSC modes 16 QAM, 64 QAM and hierarchical (HMmix, HMsym) – SDC modes 4 QAM and 16 QAM – Interleaver length 0.4s and 2s – EEP (equal error protection) and UEP (unequal error protection) with all possible combinations of protection ratios / code rates – DRM+ option: robustness mode E, 100 kHz, MSC modes 4/16 QAM, SDC modes 4 QAM code rate 0.5/0.25, interleaver length 0.6s DRM signalling options: – Service ID – Service language (short list for scanning and detailed list covering all worldwide languages) – Service programme type – Country of origin – Current time and date, including local time offset – Alternative frequencies for the whole DRM Multiplex and individual DRM services – Announcements (traffic, news, weather, alarm, etc.) Full Unicode / UTF-8 support (all international characters, ISO 10646) for DRM TextMessages and DRM service labels. – Detailed system status information via HTML – HTML access to detailed log files for inspection and download – System configuration backup and restore mechanism (remote and local) Administration and data provision are based on Ethernet network or modem dial-in connections featuring a detailed user management. The strong firewall functionality guards the access to the system. Hardware The audio A / D conversion and system synchronization rely on a GPS clock source. Alternatively the system synchronization can be done via network timing protocol (NTP). The Fraunhofer DRM ContentServerTM R4 is based on robust and redundant 19" server hardware for reliable 24 / 7 operation. A console display is supported to locally activate configurations, to monitor the system status and to setup the basic hardware parameters. The system as a complete package including hardware and specific customers support services is available from our OEM Partners. Advanced System Features Automatic broadcast scheduling: – Global broadcast calendar – Unlimited weekly calendars – Manual, SNMP triggered, or scheduled broadcast activation / reconfiguration Sound system configuration: – Live audio level monitoring via web browser – Audio amplification setup – Audio clipping and silence detection – Optional MP3 normalization on import Powerful security features: – Professional firewall – Secured connections for administration and data upload – Continuous system self-monitoring – Monitoring of attached uninterruptible power supplies (UPS) – System status signalling via e-mail report system, console, relay card and SNMP *feature is under development – – – – – – – – – – – – – – – DRM Multiplex Generator Fraunhofer Institute for Integrated Circuits IIS Executive Director Prof. Dr.-Ing.

It provides the full functionality of the DRM system with regard to signalling and transmittable content (incl. dynamic reconfigurations). Basic Standard Professional Developer Basic Edition Available options Compact The Fraunhofer DRM ContentServerTM R4 is available in three Editions (option packages). All Editions share all the basic DRM functionality, but each Edition provides a different level of system functionality by default. All Editions can easily be extended by additional features at all times. – Basic Edition The perfect starter kit for smaller broadcasters or for use at the transmitter site (accompanying a DRM Modulator) with the option of future extension to the customer´s growing requirements – Standard Edition Combines the most important DRM features (like AFS) and functionality (like Broadcast Scheduling) for easy integration into a studio or playout center environment – Professional Edition Extends the Standard Edition by professional automation features and provides the full range of individual data transmissions as well as standardized multimedia applications like DRM-EPG Compact Editions DRM TextMessages Journaline® EPG – Electronic Programme Guide MOT Slideshow MOT Broadcast Website/ Transparent File Transmission TPEG traffic information TMC – Traffic Message Channel PRBS Generator (sync/async) IP Insertion TDC – raw data (any individual data on any protocol level) Support for multiple MOT priority classes – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – Data import methods Import via HTML interface Import via file FTP upload Import via HTTP/FTP mirroring Import via live socket connection Import from existing RSS sources (TextMessages + Journaline®) Import from Funkhaustelegramm, UECP, Zenon, Leitungsprotokoll (TextMessages + Journaline®) Import via automatic scheduled mirroring Secure data import connections – – – – – – – 1 – – – 1 – – – – 1 1 1 1 2 2 1 1 1 Symbols: Option is included in the package – Option is not included but can be added to the package Option can not be combined with the package Note: This list is informative only.
