MaxLinear Inc. and STMicroelectronics are set to unleash a next-generation multi-channel ultra-high definition (UHD) set-top box (STB)/server platform. The 4K UHD satellite server platform is geared for the growing number of satellite pay-TV operators looking to deliver broadcast 4K services along with other value-added features such as multi-channel recording, multi-room viewing and content streaming to multiple devices throughout the home.

The platform features the MaxLinear MxL582 Full-Spectrum Capture (FSC) satellite receiver, which captures the entire satellite RF band and provides up to eight DVB-S/S2 transport stream outputs. The MxL582 is part of the MxL5x2 family of SoCs that feature complete, single chip multi-channel receiver solutions with no external LNA, ultra-low power consumption and industry-leading performance, detailed the companies. The MxL5x2 SoCs support single cable (unicable) distribution and Extended L-Band (XL-Band) input frequencies from 250-2350MHz.

The STiH412 from ST handles the back-end decoding and video processing in the design. This SoC provides high-efficiency video-decoding (HEVC/ H.265) multi-channel decode, UHD display, multi-channel recording to an internal or external hard drive, video-on-demand (VOD) and real-time transcoding of up to three streams and modern HD graphics.

The ST Cannes/Monaco SoC design is based on dual-core ARM processors, superior 2D/3D graphics performance with a Mali GPU, integrated hardware Faroudja multimedia subsystem with HEVC video decoder, high-performance video encoder and high-quality video pre- and post-processing.

The MxL5x2 family includes two devices with XL-Band support, MxL582 and MxL542. The MxL582 includes two XL-Band inputs and eight demodulators. The MxL542 includes two XL-Band inputs and four demodulators. Both devices are pin-compatible and integrate an RF splitter, which enables flexible designs that can support from four to 16 demodulators with common hardware and software. MxL5x2 devices are in volume production and available in a low cost 10 x 10mm QFN package.

The MxL5x2 devices integrate all active front-end components, including the low-noise amplifiers (LNA). Due to the high levels of system integration, the BOM in end applications is reduced to a minimal number of low-cost passive components.

The low-power and power-control flexibility of the MxL5x2 devices enable compliance with the requirements of Energy Star and the European Code of Conduct for Digital TV Services and Broadband Equipment, in both standby and full operating modes.

The Monaco SoC family claims to provide an economical, yet full-featured solution for media server applications. It delivers high computing capabilities based on ARM multi-core processors, superior 2D/3D graphics performance, and integrated hardware video encoders with pre-processing and Faroudja-enhanced video processing. The devices also feature a comprehensive security toolbox for premium content delivery. The ST Faroudja Transcode Engine claims to provide best-in-class transcoding capabilities for multi-screen experiences across consumer and handheld devices. This allows operators to reduce their network bandwidth while offering an excellent quality of service throughout the home. The Monaco family includes the Ultra HD STiH412 and cost-optimised derivatives (STiH410) for full HD (1080p) markets.
