2 /DRM ContentServer What Is It? One-Box Encoder Solution for Digital Radio Real-time audio encoding (DRM xhe-aac, DRM AAC, Classic, +, Surround) Data Application Management (DL+/TM, Journaline, SLS, EPG, TPEG, ) Multiplex Generation (dyn. reconfigs) Monitoring / verification / logging 2

4 /DRM ContentServer Interfaces Content contribution (possibly public) Firewall Multiplex distribution (protected) Broadcast Configuration/ System Administration remotely via network (http/https), using a web browser like Firefox internal Content Providers (data sources) local network Internet external Content Providers (data sources) local audio analog/digital ftp(s), http(s), mirroring, RSS/Atom, real-time socket, audio file upload (mp3/wav), Livewire audio-over-ip, UECP STI-D/STI-C/ETI via EDI/DCP (from Service Multiplexer) time sync (GPS, NTP) Local administration console: network/hardware config, broadcast configuration selection ContentServer R5 AudioServer Multimedia DataServer DMB Gateway Multipex Generator IP Continuous self-monitoring, System status signalling: reports, SNMP, relay-card, local console, web interface (status/logfiles) Multiplex via EDI (FIC, MSC) full SFN support EDI/DCP standardized protocol (optional legacy interf. G.703, X.21) DCP: UDP/IP, serial (RS-232) connections, local or long-distance all DCP features: FEC, interleaving, fragmentation, network load balancing ETI via EDI/DCP STI-D/STI-C/ETI via EDI/DCP Monitoring Modulator(s) at transmitter site(s) Service / Ensembe Multiplexer sync. EDI Redundancy Group Feature: multiple ContentServers per group (2 or more) full failover: each group member independently generates frame-synchronous and co-timed EDI signal group-wide synchronized dynamic reconfigurations single user interface: automatic replication of broadcast configurations, schedules, uploaded content mutual system health and availability checks among members 4

5 ContentServer Customized Feature-Sets Individual system functionality according to customer needs Pre-defined feature collections Editions : Community Edition Standard Edition Professional Edition Developer Edition License management: USB or SW (system upgrades via file) Optional limited runtime: demos, exhibitions, renting, 5

6 /DRM ContentServer OEM Partners ContentServer Technology Basis for products of our OEM Partners OEM Partners for ContentServer: IZT, AVT, Broadcast Partners, RFmondial, VDL, A-Media, OEM Partners for DRM ContentServers: Ampegon, Transradio, Nautel, Continental, BECIL, 6

7 /DRM ContentServer in Redundancy Group mode Distribution Redundancy with EDI & MDI Single user interface for configuration & scheduling (web browser), data upload (ftp, ftp/http mirroring) local audio + real-time data input Individual system configuration access (web browser), if required Multiple ContentServers combined to a Redundancy Group ContentServer AudioServer Multimedia DataServer Multipex Generator ContentServer - automatic synchronization - uploaded data distribution (IP) - audio cross redundancy ContentServer Optionally > 2 systems per Redundancy Group modulator / transmitter or EDI/ETI Switcher with redundant EDI inputs EDI/DCP outputs: frame-synchronous (including dynamic reconfigurations) independently generated by each ContentServer detailed content quality indicators (audio errors etc.) 8

8 /DRM ContentServer in Redundancy Group mode Distribution Networks Multi-Site Example Site Oslo A Site Oslo B Disaster recovery site Redundancy Group A -CS 'EnsMux' (for region A) -CS 'EnsMux' (for region A) -CS 'EnsMux' (for region A) Redundancy Group B -CS 'EnsMux' (for region B) -CS 'EnsMux' (for region B) -CS 'EnsMux' (for region B) Redundancy Group SMux 1 -CS 'ServiceMux' (national services) 1 -CS 'ServiceMux' (national services) 9

9 /DRM ContentServer in Redundancy Group mode Example: German Multiplex Launch configuration 2011 DRadio, Köln: Service Multiplexer 1x -CS Redundancy Group DRadio, Berlin: Service Multiplexer 1x -CS Regiocast, Leipzig: Service Multiplexer 2x -CS Media Broadcast, Frankfurt: Ensemble Multiplex Head-End 2x -CS ETI Distribution via Sat/G.703 FhG-IIS, Erlangen: Service / monitoring access 10

10 Extended STI-C : Multi-Regions + Shared Services Overview ETI vs. STI-D vs. STI-C Audio, Video & Data Service Encoders Service Multiplexer Service Multiplexer Service Multiplexer STI-D STI-D Service Multiplexer STI-D STI-D STI-C Ensemble Multiplexer ETI ETI Modulator (COFDM) Modulator (COFDM) STI-D: Service Transport Interface Data Part, STI-C: Control Part ETI: Ensemble Transport Interface One or more Service Multiplexers feed one Ensemble Multiplexer n:1 STI-C enables autonomous configuration & management of Service Muxs. 11

11 Extended STI-C : Multi-Regions + Shared Services Application of STI-C Typical use-case Service Multiplexer Sub-Multiplex A Locally encoded services Sub-Multiplex Ensemble Service Multiplexer B Sub-Multiplex Ensemble Multiplexer Multiplex (EDI) Service Multiplexer C Resulting Multiplex Configuration (example) Inserted parts of submultiplexes: Services A Services C Services B 12

12 Extended STI-C : Multi-Regions + Shared Services Application of Extended STI-C Shared Services Ensemble Multiplexer Ensemble Multiplexer Region B Local Region A services Local Services Central Service Multiplexer Extended STI-C Local services Ensemble Multiplexer Region C Resulting Multiplex Configuration for Region C (example) Local services Shared Services (via STI-C) Local services 13

13 Extended STI-C : Multi-Regions + Shared Services Application of Extended STI-C Extended STI-C for Multiplexes: Local services encoded locally in multiple regions Un-used capacity in each region managed centrally with 1 single Service Multiplexer Benefits over legacy sub-channel extraction: Full config autonomy for shared content and regions, respectively: minimizes effort and complexity Match of all IDs + parameters in all regions at any time Time-synchronous re-configs, announcements, etc. in all regions Minimizes hardware, rack-space, audio-wiring, data interfacing, etc. Reduces cost and complexity for system setup and operation 14
