Harris introduces upgrade for China’s DMB-T standard

MUMBAI: International communications and information technology company Harris has introduced its first transmission solution for China’s Digital Multimedia Broadcast-Terrestrial (DMB-T) standard at the upcoming BIRTV show in Beijing, China.

The company is also shipping its first DMB-T transmitter to Yunnan TV in China later this month and will provide upgrade kits for Harris DVB-T transmitters currently installed in China.

 

Harris debuted the DMB-T transmitter outfitted with a new Harris DTV660 DMB-T exciter. The DTV660 DMB-T exciter is based on Harris‘ field-proven range of Digital Video Broadcast-Terrestrial (DVB-T) standard exciters, and features a new modulator designed specifically to meet the new Chinese digital TV standard.

The new DMB-T transmitter uses Harris Atlas technology, which includes a variety of solid-state, air-cooled and liquid-cooled analogue and DVB-T digital transmitters.

Harris Atlas DVB-T transmitters already in the field today can be upgraded to the DMB-T standard with a board swap and firmware changes.

 
Harris broadcast communications president Tim Thorsteinson says, "Harris is pleased to support China’s DMB-T standard for digital terrestrial television. Harris has a long history of leadership in transmission, and continues to design new platforms and modify existing technology to support digital TV standards internationally. We look forward to supporting this unique standard as China moves forward with its DTV initiatives for both terrestrial and mobile TV broadcasting."

The DMB-T standard has been designed to provide the best possible reception quality, even in large metropolitan areas with difficult reception conditions. The standard has been engineered to provide a very high level of spectral efficiency. This provides the capability to transmit multiple programs of video, audio and data within the same channel that was previously occupied by a single analog signal. The standard is also designed to allow both terrestrial TV sets and mobile handheld devices to use the same spectrum.

The medium-to-high power liquid-cooled design of Harris DMB-T transmitters is specifically for broadcasters seeking an efficient, high-power density transmitter, resulting in greatly reduced room air-conditioning requirements and overall electricity costs.

The new Harris DMB-T transmitter series also shares the compact footprint of the Atlas transmitter design for broadcasters with limited space in the transmission facility.
