The DVB-H technology is a DVB-H in a hybrid network structure spin-off of the DVB T standard. It is to a consisting of both a mobile large extent compatible with DVB-T but communications network such as takes into account the specific properties GPRS or UMTS and an additional of typical terminals, which are expected DVB-H downstream.

The set of specifications for IP standalone or as an enhancement of Datacast (phase1) was approved by mobile telecommunications networks DVB in October 2005. which many typical handheld terminals In Japan, a system called ISDB-T are able to access anyway.

The broadband, feature that ISDB-T adds to DVB-T is introduction of additional forward error DVB-SCENE : 03 high capacity downstream channel the possibility of splitting the channel correction etc., the data rate available provided by DVB-H features a total data bandwidth into segments. The data rate using DMB in that channel is rate of several Mbit/s and may be used which can be transmitted in one approximately 1 Mbit/s. “...can be used standalone or as an enhancement of mobile telecommunications networks...” for audio and video streaming segment is limited to approximately 400 FLO (Forward Link Only) is the brand applications, file downloads and for kbit/s.

It is probably fair system thereby introduces new ways of channel targeting small screens can be to say that FLO was developed as a distributing services to handheld received on terminals with a narrow- response to DVB-H and is based on terminals, offering greatly extended band tuner thus reducing the power know-how gained by analysing the possibilities for content providers and consumption of the tuner.
