DAB-IP - Movio<br />

DAB-IP (Digital Audio Broadcast - Internet Protocol) is a variant of DMB. It's being called<br />

Movio and uses technology <strong>de</strong>v<strong>el</strong>oped by BT and Microsoft. Virgin Mobile was first to the UK<br />

market with a working offering using Movio in 2006. There's ev<strong>en</strong> a DAB-IP handset – the<br />

Trilogy- which has be<strong>en</strong> <strong>de</strong>v<strong>el</strong>oped by HTC (the firm behind O2's XDA range, for example).<br />

DVB-H<br />

In terms of <strong>de</strong>ployed networks, however, DVB-H (Digital Vi<strong>de</strong>o Broadcasting)-Handh<strong>el</strong>d is<br />

curr<strong>en</strong>tly the clear winner. (Previously known as DVB-X, too). Effectiv<strong>el</strong>y this is the r<strong>el</strong>evant<br />

mobile TV standard set for Europe by ETSI (the body which originally gave us GSM). It is being<br />

heavily supported by Nokia and O2. As the name implies, DVB-H is a version of an existing<br />

digital TV standard – but optimised for mobile phones and PDAs. However, it does require<br />

existing programme material to be re-broadcast – h<strong>en</strong>ce the trials to discover what handset<br />

owners want to view. Sadly, the r<strong>el</strong>evant spectrum for DVB-H won't be free in the UK until<br />

2012. DVB-H handsets have come from LG.<br />

ISDB-T<br />

The Japanese have adapted their existing digital TV standard for use with mobile phones. It's<br />

called Integrated Services Digital Broadcast – Terrestrial (ISDB-T). To provi<strong>de</strong> the<br />

interactivity (or 'back' chann<strong>el</strong>) another standard called STD-AXX is utilised. Like i-mo<strong>de</strong>, can<br />

ISDB-T ever succeed outsi<strong>de</strong> Japan?<br />

MBMS<br />

Another possibility is MBMS (Multimedia Broadcast and Multicast Services) which has be<strong>en</strong><br />

put together by the 3GPP. Its major backer appears to be Ericsson. MBMS can be offered via<br />

existing GSM and 3G networks. Better still, it inclu<strong>de</strong>s an uplink chann<strong>el</strong>, not avai<strong>la</strong>ble in rival<br />

technologies like DVB-H (backed by Nokia) or DMB (active in Asia). MBMS is a kind of TV<br />

version of multimedia messaging (MMS) andis akin to s<strong>en</strong>ding TV clips simultaneously to<br />

multiple<br />

recipi<strong>en</strong>ts.<br />

MediaFLO<br />

A proprietary system, MediaFLO, has attracted supported in the USA but requires building out<br />

a separate network. Qualcomm’s new air-interface technology, 'FLO' (Forward Link Only) is<br />
