| TL811 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 integrated GLOBAL AND SCAL ABLE 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 TeraLogicOs 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 N 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. circuits CPU CPU Interface (SysAD Bus) Local Bus SDRAM (Unified for CPU) Memory Controller ATSC/DVB/DIRECTV(R)/ARIB Local Bus Controller T/S in 1 T/S in 2 Demux 2 Transport Out Transport In Transport In Demux 1 T/S Out Descrambler 1 Transport In & Out T/S in 3 Descrambler 2 DTV I/O I2C SmartCard GPIO UART I2C SmartCards GPIO UART PVR I/O IDE PCI BUS IDE T L 8 1 X B LO C K D I AG R A M PCI Bus TL811 STB/PVR Controller IC APPLICATIONS Set-Top Boxes Digital TV Personal Video Recorders SUPPORTING TERALOGIC PRODUCTS TL85x Decoder ICs Cougar Development Platform PROGRAMMABLE TRANSPORT INPUT/DEMULTIPLEXER Two dedicated and one bi-directional transport input ports One dedicated and one bi-directional transport output ports Glueless interface to IEEE 1394 devices Two ATSC/DVB/ARIB/DIRECTV compliant demux Glueless interface to most front-end ICs Maximum input bit rate of 80 Mbits/sec supported on each port Ability to transfer multiple SD streams to the TeraLogic DTV Decoder for SD PIP applications DESCRAMBLERS DVB, DIRECTV DES-ECB, MPEG DES, Triple DES-CBC, Multi-2 descrambling supported Simultaneous descrambling of two streams supported All three transport input ports can access the descramblers Bypass mode of transport streams supported CPU INTERFACE Glueless interface to MIPS CPUs such as QED RM5231, NEC VR5432 32-bit wide multiplexed address/data supported Write and Read posting buffers between CPU and external resources (PCI, memory bus and local bus).
