DVB-H / DVB-SH / DVB-T iSplicer


The DVB-H / DVB-SH / DVB-T iSplicer is a key component of high revenue generating and cost-optimised Mobile or Terrestrial TV networks. It enables the primary distribution of Mobile or Digital TV content directly to the DVB-H, DVB-SH or DVB-T broadcast towers. The distribution can be done via standard satellite links, microwave, leased lines, IP multicast networks or technologies any mix of these distribution. The dynamic isochronous content adaptation feature allows the highest degree of flexibility in the definition of service packages and enables innovative advertising schemes.

UDcast DVB-H iSplicer

This DVB-H / DVB-SH / DVB-T distribution engine, designed for installation at transmission towers and cellular base stations integrates three major broadcast network functions:

Distribution Network Adapter

  • Enables distribution of MPEG2 Transport Stream via satellite data links or any type of ASI or IP multicast networks.

Isochronous DVB-H/DVB-SH/DVB-SH Splicer

  • Dynamic local selection of national, regional and local content.
  • Selection of channels directly within the Transport Stream (re-multiplexing).
  • Bandwidth optimization on the distribution link (no redundancy).
  • Isochronous operation enabling content selection with SFN and MFN cells.

MIP Inserter

  • Insertion of MIP (Megaframe Information Packet) or SHIP (SH Initialization Packet).

SHIP Inserter

  • Insertion of SHIP (SH Initialization Packet).

iSplicer is compliant with DVB-H, DVB-SH and DVB-T standards, and fully interoperable with all DVB-H / DVB-SH / DVB-T standard equipment (terminals, encoders, modulators, network adapters, ESG and CA/DRM systems).

The iSplicer is configured in-band, meaning the entire network is managed globally through the central IPE/iSplicer Manager. The DVB modulation parameters are passed to the modulators/transmitters via the MIP/SHIP protocol, allowing central management of the transmission parameters from the Head-End. These parameters can be adjusted centrally over the lifetime of the transmission network.

The different SFN cells in the transmit areas can have different modulation parameters, allowing maximum coverage optimization.

The iSplicer receives, modifies and re-transmits the MPEG2 Transport Stream while assuring the integrity of the modified stream. The iSplicer also guarantees the synchronization between modulators when they transmit at the same frequency. Multiple iSplicers can operate jointly within the same SFN (Single Frequency Network) cell.

The iSplicer helps to optimize the capital and operating expenses (CAPEX/OPEX) of large DVB-H and DVB-SH deployments, enabling significant cost savings of up to 40%. The iSplicer can also reduce network deployment time, and increase service and advertising revenues thanks to its addressable approach to content and advertising distribution. The number and size of local broadcasting areas can be dynamically defined via the IPE/iSplicer Manager.
