To accelerate the development of mobile TV receivers for China's recently announced digital TV standard, Analog Devices Inc. and Legend Silicon Corp., a supplier of silicon solutions for broadband wireless broadcasting, have crafted a platform by combining demodulators from Legend with low-power RF tuners from ADI's Integrant Technologies. It also leverages ADI's low-power Blackfin processor to perform the MPEG-2 decoding and multimedia processing functions in mobile TV applications. The partners have worked for two years on the development of fixed and mobile TV technologies to support the reception of the new Chinese digital broadcast.

This solution was demonstrated at the International Mobitv Summit & Show 2006 in Shenzhen, China. The new digital terrestrial TV broadcasting standard, coded GB 20600-2006, was announced by the Standardization Administration of China on Aug. 30, 2006, and will come into effect on Aug. 1, 2007. Legend Silicon is the first company to provide a demodulator compliant with the standard, according to the partners.

As per ADI, this solution will enable users to quickly integrate digital reception into a range of portable devices, including portable media players (PMPs), PDAs, smart phones and laptops. ADI completed its acquisition of Integrant Technologies in July. Legend Silicon's demodulator was designed from the ground up to provide services for fixed terrestrial high-definition television (HDTV) and mobile broadcasts. Based on time-domain synchronous-orthogonal frequency division multiplexing (TDS-OFDM) technology, this solution is crafted to provide continuous reception in the challenging conditions of a mobile environment, as well in fixed applications in urban environments where severe multipath interference is a problem.

“As the 2008 Olympic Games in Beijing approach, we expect the Chinese market to rapidly deploy digital broadcast TV services with millions of consumer electronic devices equipped to receive digital broadcast signals,” said John Hussey, vice president of High Speed Signal Processing, Analog Devices. “Initial rollout will begin in set-top boxes, automobiles and televisions, followed soon after by high-end PDAs, smart phones and portable media players. By 2008, the total market size of mobile TV applications in China is expected to be upward of tens of millions of units. Ultimately, the technology will be adapted for mass market mobile phones.”
