These second-generation 4K set-top-boxes will come in small and cool form factors and allow users to enjoy a richer, more immersive Ultra-HD experience delivering fast, crystal-clear sports action and increased color fidelity together with the increased media-content resolution.

With these four new SoCs, identified as STiH314/318 and STiH414/418, ST is leveraging the market success of its widely-deployed STiH312/Cannes and STiH412/Monaco architectures.

The STiH314/318 and STiH414/418 additions now extend the market reach from the most cost-sensitive to the highest-performance use cases. In addition, the availability of mature software allows faster time-to-market and complete re-use of already deployed middleware while low-power operation enables re-use of existing HD form factors.

"With these new devices, ST is broadening its family of complete integrated solutions for set-top-boxes," said Gian Luca Bertino, Executive Vice President, General Manager, Digital Convergence Group, STMicroelectronics.

"As the share of UHD TV shipments are expected to grow from about 6% of TVs sold today to over 30% in the next 5 years, ST is in the pole position to enable its customers to be the winners with the industry’s most cost-effective and power-efficient solutions for next-generation TV services."

Manufactured in 28nm process technology, ST’s new Cannes/Monaco-compatible set-top box SoC devices will be available with complete software support to major OEMs in Q4 2014.
