Standards For IPTV over DVB-H

The DVB-H standard is designed to support unicast broadcasting of IP datagrams to handheld devices, including mobile phones...


DVB-H is specified in ETSI standard EN302 304. Because it is intended for delivery to handheld devices, in incorporates techniques to combat Doppler shift and to minimise power consumption in the receiving device (by using a time-sliced transmission mode, rather that the conventional transmission of DBV-T, for example. It can co-exist on the same transponders as DVB-T provided a suitable frequency allocation is available. This is attractive because with minimal infrastructure change the same transmitter sites can support content simultaneously to fixed (FTA) and mobile terminals.

To provide a reverse channel, implementations are typically integrated with the data services of GPRS or UMTS. This allows usage information and potentially quality of service (QoS) information to be returned to the service provider.

Key Mobile TV Technologies

Several technologies and standards are typically implemented in an overall mobile TV solution:

  • DVB-H (or the competing standards for transmission to handsets)
  • DVB-IPDC for additional protocol layers and features, including reliable IP datagram delivery to/from handsets
  • H.264/MPEG-4 encoding of video signals to achieve high compression and quality
  • OMA BCAST for supporting services, such as Electronic Programme Guide (EPG), terminal provisioning, notifications and interactive services
  • OMA BCAST Smartcard or DRM for Digital Rights Management of content
