DVB/H
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.
