TL880  
DTVPC Decoder  
All Format Digital TV decoder for PC OEMs and add-in card manufacturers  
HIGH DEFINITION EXPERIENCE  
The TL880 IC is a highly integrated All Format Digital TV decoder designed for the PC platform. It is the first IC product in the  
PC industry to be compliant with all ATSC and ARIB Digital TV formats including high definition DTV resolutions for superior  
video quality. The TL880 architecture supports multiple international standards including ATSC, the European DVB, the  
Japanese ARIB standard, as well as proprietary standards such as DIRECTV®. The TL880 can decode a single HD program or  
up to four SD programs simultaneously for advanced features such as multicasting. The on-chip display processor with its state-  
of-the art filtering algorithms can up/down-convert any ATSC-format input and output in any common display resolution while  
maintaining the high definition video quality. Additionally, the TL880 IC can capture decoded NTSC video and up-convert it to  
HD video  
formats for a richer viewing experience.  
GLOBAL AND SCALABLE ARCHITECTURE  
With its high level of integration and optimized architecture, the TL880 decoder  
delivers an affordable advanced Digital TV solution for the PC platform. It integrates  
an All Format MPEG2 MP@HL video decoder, display processor with scan rate  
converter, an ATSC/DVB/DIRECTV transport demultiplexer and PCI-bus interface  
on a single chip to enable small footprint circuit board designs. The TL880 archi-  
tecture is optimized through appropriate system integration to minimize the glue  
logic needed for interfacing with peripheral components. An integrated 2D graphics  
accelerator renders text and graphics to an independent on-screen display (OSD)  
bitmap.  
The TL880 architecture is suited for PC applications with its PCI interface, high level of integration and PC screen format  
support. No external bridge chip is required for connecting the TL880 IC to the PCI bus resulting in significant cost savings for a  
DTVPC implementation. The TL880 decoder can be programmed to support standard PC resolutions enabling the display of  
Digital TV on 4:3 aspect ratio PC monitors. The TL880 IC is an ideal solution for bringing the advanced Digital TV experience to  
the PC consumer at a mainstream price point.
