The Mobile Digital TV Market
The Mobile Digital TV Market
Mobile digital broadcast TV (DTV) combines the two best-selling consumer products in history - TVs and mobile phones. TV will be an ingredient that drives demand for the next generation of wireless mobile phones because consumers want both communications and entertainment - all in one place and in one device. It is currently assumed that users will "snack" on 15-20 minutes of TV programming at a time to catch up on news, sports, weather, major events such as the World Cup or Olympics, and more in real-time using their mobile phone at speeds comparable to watching their TV at home.
Industry leaders form a Mobile DTV Alliance to support the DVB-H standard
At every level of the mobile DTV value-chain carriers, handset providers, infrastructure owners, content providers, broadcasters and semiconductor suppliers are putting increased efforts behind their mobile DTV plans. And for good reason -- according to Vision Gain, the mobile DTV handset market is expected to grow to over 105 million units by 2009 from the expected five million units in 2005.
Standards Landscape Worldwide
Like most new technologies, there are several different standards for mobile DTV around the world. These include three primary open standards for the mDTV marketplace:
- is quickly gaining ground with trials in Europe, the U.S., Australia, and parts of Asia.
- ISDB-T (integrated services digital broadcast - terrestrial) is the standard in Japan and will be in trials later in 2005.
- DMB (digital media broadcast) has deployed today in Korea with several handsets already in-market to support the standard and is expanding to Europe and other parts of Asia.

The 3G and upcoming HSDPA networks will have a role in the mobile DTV market as well. While the economics and bandwidth requirements of streaming live broadcasts over the cellular network would impact voice services, using 3G or HSDPA networks to download clips or full television shows to memory is practical. Users could watch live events using the broadcast link on their phone and download news or sports clips like they do today on the Internet using their PC. And as personal video recording (PVR) capabilities and user preference programming becomes available on mobile phones, carriers will be able to provide overnight download programming or clips to a user's mobile phone while cellular network utilization is extremely low.
DVB-H: An Open Standard to Accelerate Digital Mobile TV Deployment
DVB-H is an open, non-proprietary standard that will foster growth throughout the wireless ecosystem, allowing mobile Digital TV (DTV) handsets and services to reach the mass market faster and at a lower cost to consumers.
