STMicroelectronics N.V. has introduced a portfolio of set top box (STB) SoCs for HD terrestrial, cable IP and satellite equipment that claim to enable Internet-based services in price-sensitive markets. Manufactured in 40nm process technology, the ICs boast enhanced processing engine with integrated on-chip features that simplify STB design, allowing operators to take advantage of lower-cost memories and meet the latest low-power objectives.

The chips are geared for HD zappers, personal video recorders (PVR), IP clients and dual-HD boxes supporting connected-TV services such as IPTV, information channels and OTT video, gaming, catch-up TV and social networking.


The STB ICs are developed using 40nm process technology.

The devices support the full range of HD broadcast and multimedia codecs, hybrid and IP standards, the latest security and content protection standards, and important middleware stacks from the leading providers, ST noted. The ICs deliver outstanding "green" features such as the latest generation of energy-efficient Ethernet and a 0.5W stand-by mode with fast-resume capability, added the company. Code-compatible with STi7105, the devices facilitate rapid porting of existing software, permitting customers to upgrade their product platforms with minimal development costs.

The SoCs enhance flexibility for equipment manufacturers and save cost for operators through pin compatibility between two decoder-only chips and their associated packages that combine the decoder with a cable, satellite or terrestrial demodulator. This enables designers to create products for various market sectors taking advantage of extensive hardware commonality to save costs and lead times, the company indicated.

The product family includes the STiH207 decoder designed for IP client, zapper and PVR applications, the STiH237 that features an integrated Digital Video Broadcast-Satellite 2 (DVB-S2) demodulator for satellite zapper boxes, and the STiH239 that integrates a dual DVB-S2 demodulator for satellite PVR and dual HD picture-in-picture (PIP) STBs. Additionally, the STiH273/STiH223 includes DVB-T (digital-terrestrial) and DVB-C (digital-cable) annex A/B/C demodulation, while the STiH207 decoder, which adds support for1080p60 decoding, dual HD PIP and 3DTV MVC (Multiview Video Codec), is pin compatible with the STiH239, STiH237 or STiH273.

The STiH207, STiH237, STiH239 andSTiH273 are sampling to lead customers, in 27 x 27mm BGA packages.
