Single-chip STB IC packs HD, interactive combo

STMicroelectronics NV has launched a new cable STB IC that cuts the cost of set tops capable of accessing emerging high-value services.

The STi7141 is the first device on the market to combine support for high-definition TV, up to 120Mbit/s broadband, and sophisticated digital video recorder (DVR) functions in a single component, allowing providers to reduce deployment costs while also driving subscriber take-up of innovative and exciting new services such as next-generation interactivity.

The STi7141, is manufactured in 55nm process technology, supports the latest HD broadcast standards with three embedded cable receivers and multi-standard MPEG4/H.264/VC1 decoding. By also including a cable modem meeting the DOCSIS/EuroDOCSIS 2.0 standard, which enables an always-on Internet connection alongside cable TV, the IC supports IP-based interactive TV, and VoIP in addition to broadband ISP services. The STi7141 also supports DOCSIS 3.0 downstream channel bonding, which enables download speeds up to 120Mbit/s.

Unlike any other STB ICs currently available, the STi7141 supports HD and interactive capabilities, and also adds comprehensive DVR functions including trick-play modes such as fast-forward, rewind, pause, skip and slow motion. The latest consumer media interconnects are also supported, including USB, HDMI, eSATA and Ethernet ports for Internet connectivity.

"To take full advantage of cable triple-play services and enhanced interactive television, subscribers need comprehensive set-top box features at an ultra-competitive price," said Philippe Lambinet, executive VP and general manager of the home entertainment and displays group, ST. "Recognizing this imperative, the STi7141 is the first STB IC to support the latest HDTV standards, leading-edge broadband Internet speeds, and DVR functions in a single chip. This chip will allow service providers to deliver high-value experiences at the same time as reducing barriers to access for consumers."

The STi7141 is sampling now to lead customers. The device is packaged in a 35 x 35 PBGA, with pricing available on application.
