Siano’s SMS4470 provides best-in-class sensitivity, mobility, and immunity to long echo interference. Further, it supports full antenna diversity (MRC) with up to 4 receivers used concurrently, addressing the extreme requirements of automotive applications. Input to the SMS4470 is the broadcasted RF signal received by one or more antenna(e), and output is a demodulated, selected channel stream. This data is fed into an application processor capable of video and audio decompression and rendering.

The SMS4470 is complemented by Siano’s Host-API software package that includes drivers and libraries for popular host processors and operating systems. This Host-API is based on Siano’s expertise in integrating MDTV into various handheld and portable devices, including mobile phones, personal media players, portable navigation devices, PCs, and automotive applications.
