Seeking to offer better mobile TV reception and ability to tune in two channels simultaneously, GCT Semiconductor (
News -
Alert) today announced the launch of its mobile TV receiver, “GDM7302.”
Company officials describe GDM7302 as a comprehensive single-chip solution for ISDB-T one-seg and three-seg broadcasting services.
It can be configured for diversity reception, they say, which automatically receives broadcasting signals from multiple antennas with its two integrated tuners. This results in improved quality and reliability of the wireless link. GCT says its proprietary algorithm for diversity reception provides better coverage through an adaptive control scheme and optimal power consumption.
Integrating the radio frequency
front-end plus demodulator into one monolithic integrated circuit, GCT’s new ISDB-T solution enables power savings, smaller size and bill-of-materials reduction. GDM7302’s advanced features enable ISDB-T terminals to be differentiated with enhanced viewing experiences, according to the company.
Users can also configure the GDM7302’s two receiver for dual channel reception, company officials say. This enables the reception of two channels of programming, allowing for various enhanced viewing experiences such as picture-in-picture and background recording and scanning. The GDM7302’s architecture also provides other benefits, company officials say, such as fast channel switching, seamless channel handover and on-the-fly switching between the diversity and dual channel configurations.
“GCT’s ISDB-T solution enables mobile operators and handset vendors to offer superior features beyond simply watching TV on a mobile handset,” said Tomoya Hemmi, president and chief executive officer of DOCOMO Capital, Inc. “Features like diversity and dual-channel reception are poised to become popular with viewers who desire a better watching experience. And thus, we expect that GCT’s new ISDB-T solution will boost the mobile TV market with their great success.”
