STi5517 Low-cost set-top box decoder

STMicroelectronics has developed two devices for low cost cable, satellite and terrestrial STBs. The STi5516 and STi5517 integrate more core STB functions into a single device than ever before, offering STB manufacturers the opportunity to build cost-effective solutions powered by devices from the leading supplier of MPEG-2 ICs.

Used with ST’s established demodulator devices, the STi5516 and STi5517 form a complete chipset for low-cost STBs across all application areas.

The STi5517 contains additional advanced features: it supports RGB16 graphics (with anti-flicker filtering) as an alternative image format for the OSD plane. With an integrated high-performance DMA engine, it is ideal for applications requiring high-resolution graphics.

The STi5517 has built-in D1 and PCM input interfaces to allow the IC to be used in applications requiring legacy analog support.

A common programme guide can then be used for both digital and analog services.

The STi5517 has enhanced security features to help protect the integrity of set-top boxes against piracy.
