DVB IP datacast (DVB-IPDC)

DVB with IP Datacast (DVB- IPDC) is a standardized DVB service that specifies the harmonization of IP datacast services via DVB-H, DigitalAudio Broadcast( DAB), Multimedia Broadcast Multicast Service( MBMS) and UMTS.

Thanks to DVB-IPDC, broadcasters only have to prepare their TV signals for mobile TV once, regardless of the transmission technology used. DVB-H and Digital Audio Broadcast use the same transmission formats and protocols. This also means that TV cell phones only have to support one technology.

The IPDC standard is based on the German DXB project with which a high degree of harmonization with DVB-H is achieved. This technique uses the Enhanced Streaming Mode( ESM) from T-DMB and the MPE-FEC (Multiprotocol Encapsulation Forward Error Correction) from DVB-H. This allows multimedia applications to be transmitted via DAB networks, DVB-H or UMTS using the IP protocol without recoding.

DVB-IPDC is transmitted in VHF band III in the frequency range between 174 MHz and 230 MHz and can be used nationwide, whereas DVB-H is better suited for metropolitan areas.
