MILPITAS, CA, Sep 11, 2014 (Marketwired via COMTEX) -- Sigma Designs, Inc.(R) a leading provider of intelligent system-on-chip (SoC) solutions for Smart TV, Smart home and IP-based set-top-boxes (STBs), today announced the SMP8758 SoC, designed to support UltraHD (4K) resolution using HEVC (H.265) compression technology for next-generation STBs. The SMP8758 will be on display at Sigma Designs' stand #BM7 at IBC 2014, a key video industry event taking place in Amsterdam from September 12-16.
This latest addition to the Sigma HEVC chipset family leverages Sigma's industry-proven technologies such as secure media processing, multi-format FHD and UHD video decoding, VXP(TM) display processing, and field-proven AV software core. The SMP8750 family offers SoCs at multiple cost and performance combinations allowing each SoC to offer optimal performance to price ratio for multiple STB platforms from zappers, PVR capable, Hybrid-broadcast, IPTV STBs or streamer boxes. Future certification of CAS technologies and integration into the next generation IPTV/OTT ecosystem is planned.
The SMP8758 comes with a full Software Suite, including libraries and services packaged under both Linux and Android development kits for rapid development. The Reference Design Kit incorporates managed power consumption circuits and associated software in the SDK and is developed to a minimal R-BOM to allow lower cost implementations with a lower memory subsystem footprint.
