Technology designed in Belfast is set to feature in electronics giant Samsung's new ranges of smartphones, tablets and headsets which are launching later this year.
Staff from audio company CSR's Belfast offices showed off new aptX equipment at this year's International Consumer Electronics Show in Las Vegas.
CSR's aptX division is located at the Northern Ireland Science Park in Belfast's Titanic Quarter.
Belfast audio technology company APT was sold to Cambridge-based CSR for an undisclosed sum in July.
APT, founded in 1989 as a spin-off company from Queen's University, had been bought by management in 2005, with help from two venture capital firms.
Anthony Murray, senior vice president of CSR's audio and consumer business unit, welcomed the high-profile partnership.
"Samsung has established a reputation among consumers for the consistent delivery of high performance products that offer genuine innovation and exceptional value," he said.
"Samsung's decision to partner with CSR is a defining moment for our aptX solution, highlighting aptX as a true 'must-have' feature and one that consumers will start to expect as standard.
"Consumers everywhere stand to benefit from its superior wireless stereo audio quality."
Noel McKenna, CSR's senior director of aptX, also said that this link-up endorses aptX as the latest must-have feature in high-quality wireless audio products.
CSR has also linked up with the Altec Lansing company on a new Bluetooth wireless speaker, the inMotion Air.
The electronics show in Las Vegas is the most important event in the consumer electronics calendar.
This year's show has been dominated by tablet computers as rivals rush in to follow up Apple's success with the iPad.
AptX was the winner of a Best of CES 2010 Award at last year's event. The 2010 showcase also saw the launch of Google's first high-end mobile phone, the Nexus One.
