HDfury2 Features:

Main features:


HDMI input

Component (YPbPr/YCbCr) and VGA (RGBHV) video output

Sound output in both Analog and digital Optical (S/PDIF) through an innovative 3.5mm combo jack
The HDfury2 also includes many first time world exclusive features:


Perfectly centered image in all standard NTSC/PAL modes (see below)

Performs Colour Depth Upscaling in all modes (see below)

Automatic separate SD/HD color-space selection

Accept third party accessories on its output

Lowest power consumption of any converter

Software upgradeable (EDID and Firmware) to never become obsolete!

Custom profiling to match any display requirements or to limit output resolution

Screen position adjustment through firmware

Smaller and is able to handle and include more technology innovations than the original HDfury
Colour Depth Upscaling:

A world first! HDfury2 accepts both digital RGB and component (YCbCr) video over HDMI and automatically processes both correctly for zero loss of dynamic range. HDfury2 takes this HDMI standard 16-235 data and cleverly scales it to a fully maximized output dynamic range (0-255) before sending it out to the final DAC conversion stage. The result is an absolutely stunning and dynamic picture!

Technical details: Component (YCbCr) is sent in a standard 16-235 code range in the HDMI domain. Most other converters simply output this exact same range but in analog form. These other converters basically feed code 16 to the DAC when black is requested and 235 when white is requested. However, DACs do not automatically comply to video standards resulting in code 16 translating into 44mV and 235 into 645mV (if 700mV is the full range) and while black or white crush does not occur, these converters limit the dynamic range resulting in a less than optimal picture. This is highly noticeable when you compare full range (0-255) vs. limited range (16-235).

Perfectly centered image:

Another world first! HDfury2 is the only device that recreates the sync and timing alignment completely and therefore perfectly centers the image according to the SMPTE standards in all modes. This is a major difference in the architecture. No other converter can compete against recreating the syncs completely.

Technical details: RGB as defined by CEA861A/B/C/D specification defines the leading edge of HSyncs at different locations than the SMPTE/ITU standard does for component (YPbPr). This is why ALL but one direct RGB to component converters fail to correctly center the picture. Others disregard time-domain correction placing the image too far "left" on the screen. This is the reason why people using the original HDfury coupled with a typical stand alone converter fail even though the original HDfury is not doing anything "incorrectly". It simply passes information which will be interpreted incorrectly by many TVs. As well, while less important (but still missing from other converters), HDfury2 outputs tri-level syncs in all HD modes as required by standards. Again, no standalone RGB-converter does this. We have never come across or heard from a customer of a TV that requires tri level sync but still it's nice to meet the spec and be able to claim compliance.

支持下。.我有 FW900....一直想买 HDfury...但就是太贵了。.
目前用的HD VGA RUSH...1080I 已经很满足了。哎...

我和你一样的，但是我听说hdfury效果是很“雷”的，所以迟迟没有下手！
