ATSC Mobile Digital Television
Mobile DTV is an exciting approach to delivering high-quality, large-scale multimedia content services to mobile and video devices, such as mobile phones, portable media players, laptop computers, personal navigation devices and automobile-based “infotainment systems.”
For ATSC broadcasters, mobile DTV represents a significant new revenue stream, as well as an innovative way to reach new audiences. Implementation costs are relatively low. Mobile DTV’s “one-to-many” broadcast model delivers streaming and on-demand multimedia content at a lower cost per viewer than all other schemes that rely on “one-to-one” data transmission, such as packet cellular video.
ATSC A/153, the technology standard for mobile DTV, enables local TV stations to deliver live, digital content by overlaying the signal upon their current DTV infrastructure — without the need for additional broadcast spectrum.
