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[edit]

  • 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[edit]

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