General Information
Introduction
The STD2000 is a highly-integrated, high performance system-on-chip iDTV processor that
combines Set-top Box decoding facility with a powerful TV processor.
A dual-channel PIP/PAP video processor supports High Definition formats. Its advanced integration
drastically reduces integrated Digital TV BOM costs by removing redundancy between Analog and
Digital source video processing.
Compliant with worldwide standards such as ATSC, DVB-T, ISDB-T and the Chinese Digital
Terrestrial Standard, the STD2000 also includes a built-in CableCARD™ interface for US
OpenCable™ specifications and a dual DVB-CI interface for European DVB-T specifications.
