Hardware Video Processing

CL511HN has built-in AVerMedia Video Engine technology which implements most useful video enhancing features to significantly reduce the efforts of CPU and the software development. In other words, this can help our clients to achieve the better cost saving of the hardware platform and the development resource.

Hardware Scaling, de-interlacing, color space conversion

Power-off Pass-through

Realize the Industry only “Power-off Pass-through”. Capture images even when your computer is not turned on.

Low Profile Form Factor

Suitable for small-footprint embedded platform, the compact low profile form factor design provides a better use of internal space and reduces cable routing. It increases the use of interior space for a more flexible heat spreading solution.

Built-in Signal-lock LED Indicator and RGB LED Temperature Indicator

LED for Signal-lock Indicator:

The LED light goes off when HDMI is not plugged in or there is no HDMI signal input. The LED light turns green when HDMI signal is locked (hot-plugging 5V pull high).

RGB Color LED for Temperature Indicator:

Different temperature ranges of the main chip junction temperature (Tj) will produce a different color LED:
Green is indicated for temperatures 0~73°C (32~163.4°F)
Orange is indicated for temperatures 73~80°C (163.4~176°F)
Red is indicated for temperatures 80~85°C (176~185°F)
Blinking red is indicated for temperatures over 85°C (185°F)

Support up to 4:4:4 10-bit RGB and YUV

The 10-bit color depth support is especially useful in the medical imaging applications where images with the slightest color variation may indicate different conditions or stages of diseases. This in turn may assist doctors in accurately diagnosing patient conditions.
