STi5514 Set-top box decoder with hard disk drive capability for digital TV, digital set-top box or cable box

STMicroelectronics, the world leading supplier of MPEG-2 decoders, offers a complete range of integrated circuits for set-top box applications. The STi5514 device integrates a 32-bit CPU, an MPEG2 decoder and many of the peripheral functions required by today’s powerful STBs. Additionally, the STi5514 can simultaneously demultiplex three transport streams and manage multiple descrambling modes and conditional access standards, making it the ideal solution for low cost STBs requiring DVR (digital video recorder) functionality.

Together with the STi5516 and STi5517 devices, the STi5514 provides a scalable STB decoding solution reducing time to market for manufacturers by making the reuse of hardware and software components as easy as possible across a range of products.

Complementing the STi5514, STMicroelectronics has developed the STV0299, STV0297 and STV0360 demodulator devices to deliver a complete chipset offering for satellite, cable and terrestrial STB requirements.
