The DVB Steering Board has approved the DVB-NGH (Next Generation Handheld) specification and this will now be submitted to ETSI (European Telecommunications Standards Institute) for formal standardisation. An NGH BlueBook is to be published.
The DVB hopes NGH will be the ideal solution for broadcast content delivery to handheld and mobile devices for the next decade. “NGH covers the latest modulation as well as coding technologies and can be regarded as the most sophisticated terrestrial broadcast air interface,” comments Peter Siebert, Executive Director at the DVB. “It also offers additional operational flexibility, such as different protection for audio and video streams in one service.”
Based on DVB-T2, there are many improvements and extensions in NGH to aid mobile and portable reception. These additional techniques include MIMO (Multiple-Input and Multiple-Output), Time Frequency Slicing (TFS) with a single tuner, non-uniform constellations, improved and extended LDPC codes for lower code rates, more efficient time interleaving and ultra-robust layer-1 signalling. It also covers a hybrid profile where terrestrial and satellite transmission schemes can be combined.
