The TVXPRESS TM II (TVX2) NTSC/PAL TV encoder chip is claimed to provide sharp text and graphics while substantially reducing dot crawl and color bleeding, and enables PC applications such as 3D gaming, web TV, and video conferencing to be displayed on television.

The chip integrates a multi-standard digital video encoder with three independent 9-bit output DACs, as well as a TV-out filter with an advanced, programmable multi-tap TV de-flicker and UV chroma filter. It also incorporates a flexible interface with double-clocking to support multiplexed 8-bit or 12-bit video data streams.

The TVX2 supports the YUV422 (CCIR 656) and RGB24/16 input video formats, as well as the NTSC-M, NTSC-4.43, NTSC-EIA (Japan), and PAL-B, D, G, H, I, N, M standards. With the help of the DACs, the device also extends supports to S-video + CVBS ) and SCART (RGB + C-SYNC) outputs.

In addition to the standard VESA resolutions, the encoder chip also offers 1024x768, 848x480, 720x576, and 720x480 input resolutions.

The TVX is offered in a 44-pin LQFP or 48-pin TQFP housing, and can be companion solution for the company's graphic accelerator chipsets, including the CyberALADDiN-P4 and CyberBLADE XP2.
