TL850 Digital TV Decoder integrated All Format /graphics processor for Consumer Electronic OEMs manufacturing Digital TV sets, Digital Set-Top Boxes and PVRs

GLOBAL AND SCALABLE ARCHITECTURE The TL850 has a programmable architecture that supports multiple international standards including ATSC, OpenCable, European DVB, the Japanese ARIB standard and proprietary standards such as DIRECTV®.

This single-chip solution integrates an MPEG-2 MP@HL video decoder, a display processor with scan rate converter, a transport demultiplexer and a graphics accelerator for Digital . It supports all DVB/ATSC/ARIB decode and display formats. The TL850 can handle an ATSC, DVB or DIRECTV transport stream, PES, ES and/or legacy analog formats.

MAKING TELEVISION COMPELLING AND ENGAGING The graphics processor supports a variety of graphics planes in addition to the video and cursor planes. The pixel depth and graphics resolution is selectable to allow a trade off between look and feel and memory footprint.

The TL850’s graphics engine supports high quality, flicker-reduced OSD and graphics to provide a rich, crisp, TV-centric GUI and other advanced graphical features needed for advanced STBs and TVs.

A key differentiating feature of the TL850 is the ability to do multiple standard definition decode and display. The display processor supports split screen,

picture-in-picture and picture-out-of-picture modes. These are complemented by circuits two video input ports. One port is for a transport stream and the other port is for simultaneous input of an externally digitized analog stream. The TL850 has two outputs – a primary output supporting all formats and an auxiliary output for VCR recording.
