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.

The Harris® MPH™ mobile DTV solution spans the entire mobile delivery chain, comprising content management, transmission infrastructure and digital signage, as well as test, monitoring and control. The MPH platform leads the industry with a unique, long-term service design, permitting easy upgrade to the latest profit-generating mobile DTV enhancements. Though it performs best with Harris ATSC transmitters, the MPH solution also is compatible with third-party products.

The NetVX encoding module is used to compress a single audio and video stream into the transmission format needed for mobile DTV. The encoder compresses signals using H.264 for video and AAC+ HE for audio, and outputs the resulting stream on IP, which is then encapsulated with other signals.
