SoCs for designing UHDp60-enabled “4K” STBs

STMicroelectronics has unveiled SoCs STiH314/318 and STiH414/418 for designing UHDp60-enabled “4K” set-top boxes. The new SoCs demonstrated at IBC 2014.

ST is launching these chips after success of its widely-deployed STiH312/Cannes and STiH412/Monaco architectures. ST says availability of mature software 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.

With high power efficiency and full backward software and pin-to-pin hardware compatibility with the existing Cannes/Monaco devices, the STiH314/318 and STiH414/418 facilitate seamless introduction of UHDp60-10b solutions, including an HEVC1-10-bit decoder for true Ultra-HD experience, HDMI 2.02 (6Gbps) for best quality, HDCP 2.2, and watermarking compliance with 4K content-protection requirements.

All four devices incorporate quad-core SMP3 ARM application processors that deliver 8000 (STiH314/414) or 12000 (STiH318/418) DMIPS, as well as a quad-core Graphics Processing Unit for excellent 3D graphics performance. The STiH414 and STiH418 also integrate ST's Faroudja Transcode Engine, providing best-in-class transcoding capabilities for multi-screen streaming across consumer and handheld devices. This allows operators to optimize network bandwidth while offering an excellent quality of service throughout the home. The STiH318/418 adds built-in support for VP9, the latest video-compression technology from Google.

Other key benefits include advanced security supporting concurrent conditional access, DRM (Digital Rights Management) and watermarks to protect premium broadcast content; a wide range of connectivity options including USB 3.0, PCI-e, SATA and Gigabit Ethernet; and dedicated interfaces to companion front-end solutions DOCSIS 3.0, DVB-C/DVB-S2/DVB-T2, and 802.11ac Wi-Fi devices.
