The STiH253 digital video broadcast decoder integrates a single DVB-T2 demodulator for highly integrated terrestrial set-top box.
The front end block supports DVB-C, DVB-T and DVB-T2 demodulators and FECs and sits alongside an ST40 applications CPU with 256 Kbyte L2 cache. The 16-bit memory unit supports DDR2 and DDR3 up to 667 MHz (DDR3-1333) and the chip uses the latest generation Delta decoder with ST231 core for the decoding of H.264, MPEG2, VC-1 and AVS HD or SD video streams. It supports 3DTV decoding and display, compatible with HDMI 1.4b
and has connectivity via two USB 2.0 ports, Ethernet MII/RMII/TMII port, SD/eMMC card port, Gen II (3 Gbit/s) eSATA port and PCI-e port.
The center of ST’s expanded family of set-top box (STB) system-on-chip (SoC) ICs is an enhanced processing engine with integrated on-chip features for more efficient end-product design. This robust processing engine enables operators to use lower-cost memory while meeting the latest low-power objectives. These STB SoCs support the full range of HD broadcast and multimedia codecs, hybrid and IP standards, as well as the latest security and content-protection standards with integrated critical middleware stacks from the leading providers.
ST’s chip family expands access to HD zappers, PVRs, Internet Protocol (IP) clients and dual-HD boxes supporting connected-TV services (Internet Protocol TV), information channels and Over-The-Top (OTT) video, gaming, catch-up TV and social networking.
Another addition in the Company’s set-top box portfolio, the STiH271EL, is aimed at price-sensitive markets requiring basic zapper functionality without compromise in the video performance.
The new devices add to ST’s existing line-up of SoCs for generic IP (STiH207), HD cable/terrestrial (STiH273), and HD satellite (STiH237, STiH239) set-top box applications. Pin and software compatibility throughout the family enables OEMs to optimize their design effort across multiple customer/operator cases.
“Across-the-board compatibility of ST’s family of set-top box SoCs is a key advantage for Jiuzhou,” said Huang Wei, Sales Director for Jiuzhou, a leading Chinese set-top box maker. “This uniform model design shortened our development cycle allowing us to address simultaneously the hybrid satellite, cable and terrestrial markets.”
“Replicating the success of previous joint projects, ST’s super-integrated, secure and optimized HD cable chipset with robust security delivers seamless support for our popular Inspur middleware, allowing great user experience in entry-level set-top boxes,” said Wei Cui, General Manager of Digital Media Division at Inspur, a leading set-top box manufacturer in China.
