DVB-H (digital video Broadcasting – handheld) is the new digital broadcast developed by the international DVB Project, for the transmission of video, audio and data to mobile handset terminals. It builds upon – and is largely compatible with – DVB-T standard for terrestrial Broadcasting . The standard describes several extensions to DVB-T, specifically tailored to the requirements of mobile reception and transmission environments. These extensions include time-slicing to achieve reduction of terminal power consumption, seamless service handover, and increased error correction to improve performance in typical mobile channels.


Technical Features
  • Encoding of audio, video, data, or files using H.264/AAC standard.
  • Use of IP datacasting for delivery of data to multiple receivers.
  • Organization of data into a group of packets for each channel Time slicing.
  • Insertion of appropriate signaling data for carrying the DVB-H stream information.
  • Application of forward error correction and multiprotocol encapsulation.
  • GPS time stamping for single-frequency networks.
  • Modulation using QPSK, 16QAM, or 64QAM and 4K (or 8K) COFDM carriers with frequency interleaving.
