What is the correct Mobile TV business model for operators and why TDTV is a good fit for that model? We believe that there are three keys to making a mobile TV business model work for operators. The first key is to expand the notion of mobile TV to encompass a full range of mobile broadcast services. In addition to traditional linear mobile TV, mobile broadcast can support video on demand, music downloads, weather, traffic, news, and even OTA software and application loads. As mobile broadband usage takes off with HSPA USB dongles and embedded laptops, many of these applications can be moved over to unused spectrum - but to do this - the technology supporting the broadcast network has to be completely integrated with the HSPA/WCDMA network. The second key to making mobile TV successful is to lower the cost of the platform to a point where it can support mass market demand. To do this, a technology should leverage existing 3G networks and spectrum, allow network and spectrum sharing between operators, and allow seamless handoff to HSPA in less dense regions.
