Mobile TV Ecosystem - DVB-H Headend

Roll your mouse over the diagram above and click on the hot spots to see more information about that particular TANDBERG Television product.

Throughout its history, TANDBERG Television's best-in-class solutions have made the company the global leader in video compression and have enabled it to provide video expertise across a range of platforms including terrestrial, satellite, cable, IPTV and telco networks. Now these technologies and knowledge - which include acquisition content processing, CBR and VBR encoding, multiplexing, encapsulation, modulation and network adaptation with overall system management; including automated redundancy - have been applied to the mobile world to produce a highly efficient ecosystem for broadcasting to mobile devices. This section is dedicated to the air-interface standard called DVB-H. The ecosystem components are shown above and described below:

Content reception
IRDS to receive, demodulate, descramble and decode SD MPEG-2 or MPEG-4 services with fully automated reception redundancy

AV Routing
Video and audio routing between encoders for automated redundancy and switching of input sources and outputs to encoders.

Content Encoding for Mobile
The mPlex content processing platform provides the highest quality and efficiency in compression and transport specifically for mobile TV. Up-to 8 channels of CBR or VBR encoded content can be processed in a single 1 RU chassis. Content scrambling is performed in the encoder with interfaces to CA/DRM systems and native RTP transport.

IP Switching
IP routing of multicast streams for 1+1 interface redundancy or device redundancy. Monitoring points and simulcasting

DVB-H IPE-10
The air-interface part of the solution that is specific to DVB-H, the IPE is a critical component in adapting the encoder streams to mobile transmission. Timeslicing for handset power saving and FEC for stream resilience are the primary functions of this complex processor, with the IPE-10 enabled for both a centralised model as presented, and distributed IPE architectures. Mobile service operators can be provided with access for scheduling as well as a shared operator model, providing segmented bandwidth to each.

SFN Adaptation
The use of Single Frequency Networks (SFN) in DVB-H transmissions is optional, but often highly advantageous with the amount of transmitters needed for quality indoor reception of TV. SFN adaptation in the headend provides a timing synchronization frame for the GPS-locked transmitters and enables completely bit synchronous transmission by overlapping transmit sites.

The entire ecosystem from reception to transmitter sites is managed, controlled and monitored with nCompass Control and Monitoring.

TANDBERG Television partners with leading suppliers for content protection as well service guides, incorporating these into the ecosystem connection points such as content scrambler and IPE carriage of the Electronic Service Guide (ESG).
