STB/PVR Controller IC
Multiple-transport, multiple-descrambler Controller IC for Consumer Electronic OEMs
to manufacture Digital TV sets, Digital Set Top Boxes and Personal Video Recorders
GLOBAL AND SCALABLE ARCHITECTURE
The STB/PVR Controller IC from TeraLogic is a key element of its global and scalable architecture for Digital TV. It interfaces
seamlessly to TeraLogicÕs Digital TV Decoder ICs to create a versatile solution to design consumer electronics products such
as Digital Set-Top Boxes, Digital TV sets and Personal Video Recorders (PVR) for cable, satellite or terrestrial broadcast. These
functions are integrated in a single IC Ñ multiple transport demux, descramblers, conditional access, PCI bridge, CPU local bus,
I²C, SmartCard interfaces, IDE interface, UART and GPIOs. This system-on-a-chip approach provides a very cost-effective
solution by eliminating either the need to use discrete solutions or costly ASIC development.
This IC address ES worldwide Digital TV requirements by incorporating four transport streams I/Os and multiple demultiplexers
that are compatible with ATSC, ARIB, DVB, and DIRECTV^¨. The universal appeal of this device is enhanced by the
inclusion of DVB, DIRECTV DES-ECB, MPEG DES, Triple DES-CBC and
Multi-2 descrambling schemes.
The Controller IC can be used to design next generation PVR devices with
advanced features or to upgrade an existing Set-Top Box to include PVR functions.
The multiple transport inputs enable consumer-pleasing capabilities such as the
ability to simultaneously watch and record or to have digital picture-in-picture on
any television set.
