IP over DVB

IP over DVB or IP over MPEG implies that Internet Protocol datagrams are transferred over the MPEG transport stream, and are distributed using some digital television system, for example DVB-H, DVB-T, DVB-S or DVB-C.

Application examples

  • Data broadcast (datacast), for example a data carousel sending programme information and media over and over again.
  • IP Multicast, for sending media efficiently to a limited group of subscribing users, using only the transmitter towers where users for the moment are situated.
  • interactive TV services
  • To provide internet access by utilizing the DVB system as a broadband downlink, in combination with some narrow-band duplex system. Examples:
    • Satellite Internet access, e.g. to buildings in the countryside, using a telephone modem as the back-channel
    • Broadband Internet access to trains
    • Mobile broadband internet access to cellular phones including a mobile TV receiver, for example a DVB-H receiver.

Return channels

All services except the first requires some kind of return channel.
