Nearly 120 million mobile users in more than 40 countries are expected to receive broadcast TV services by 2012, according to a new report from Jupiter Research.
That is nearly 10 times the current number of users, but the report warns that services face technological and regulatory hurdles in the interim.
The report said although the European Commission's support for the DVB-H mobile TV standard is a huge boost to that standard, it creates uncertainty for those who regard other technologies as more cost-effective.
The report also emphasised the need for regulators to make the UHF spectrum available as soon as possible, and for suppliers to ensure that broadcast TV chipsets are rapidly introduced into a wide range of handsets to promote adoption.
The report said the US will be the largest single market for mobile broadcast TV services in 2012, followed by Japan and Italy.
Advertising is expected to contribute an increasing proportion to overall mobile TV revenues, but in most cases will provide a supplementary revenue stream. Most services are expected to rely mostly on both subscriptions and pay-per-view for revenue.
