DVB approves next generation handheld TV specs

Mobile TV and video development has received a huge boost after the Digital Video Broadcasting (DVB) has approved a new specification, DVB-NGH (Next Generation Handheld) to aid mobile and portable reception.
DVB-NGH will take advantage of the MIMO (Multiple-Input and Multiple-Output) wireless communications standard with the aim of improving the efficiency and flexibility of use of broadcast spectrum.
Also covering a hybrid profile where terrestrial and satellite transmission schemes can be combined, the specification will be submitted immediately to the European Telecommunications Standards Institute (ETSI) for formal standardisation, and an NGH BlueBook is also to be published.
When first proposed over five years ago, the DVB-H mobile TV and mobile video standard was by now meant to have established itself throughout Europe and support viable commercial developments. However, the Nokia-led and partially EU-funded standard stalled, and hence mobile video has all but faded.
The DVB now says that since the introduction of DVB-H, significant changes have taken place in the delivery and consumption of multimedia content and that the standard has evolved form its original intention to provide linear broadcast services for handheld devices and now addresses the ‘profound change’ that the multimedia content market is going through and which is now defined by a wide range of rich media content consumption including traditional TV (linear), various video and audio content, images and text messages, as well as push download to local memory in the receiver.
Observing that the delivery of content now has to keep pace with the user’s demand and behaviour, the standards body says that DVB-NGH is designed to 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. Furthermore, it offers additional operational flexibility, such as different protection for audio and video streams in one service” explained Peter Siebert, DVB’s executive director.
