OVERVIEW

Fujitsu’s MB87L2250 is a single chip MPEG video and audio decoder which also includes the transport demultiplexer and 32-Bit RISC CPU. This offers a very cost effective high integrated solution for set top box applications.

MPEG decoding and transport demultiplexing are implemented in hardware. The on-chip CPU, operating at 54 MHz, is fully available for customer application software, for example the EPG function.

The MB87L2250 uses a 2.5 frame architecture which requires only one 16 Mbit SDRAM memory for MPEG decoding, OSD and section data buffering.

In addition the chip provides advanced features like letter box format conversion or teletext insertion into the VBI.
