In addition, the CPU will support transport-related software processing
including handling operations such as PSI and DVB SI tables maintenance
and private section filtering.
Compatibility and Security
The Transport Demultiplexer with 32 PID (Packet ID) is MPEG-2, DVB- and
JSAT-compliant and features a very extensive hardware-assisted PSI section
filtering scheme. This functionality is not only a superset of the standard
MPEG-2 section filtering scheme but also covers worldwide service providers'
specific filtering requirements. The integration of the DVB descrambler block
into the chip substantially increases the security of the set-top box since the
interface to the descrambler is no longer observable at the board level. In
addition to the common DVB descrambler, L64108 has integrated NDS
(News Data Service) and Multi2 (required for Japanese Market) Conditional
Access Module.
The L64108 integrates several on-chip peripherals including three RS232 seri-
al communication ports, two SmartCard ports, an IEEE1284 parallel commu-
nication port, I2C-like serial communication port, a teletext port and general
purpose I/Os.
