4K-P60 PCIE video acquisition (4Kapture family)
4K-P60 PCIE video acquisition
- Whatever your video capture needs, there is a board in this family to do the job.
- Choose from HDMI 2.0 and 12G‑SDI models that feature different combinations of SDI and HDMI connections.
- All 12G‑SDI inputs fully support HD/3G/6G-SDI.
- All HD and higher SMPTE SDI formats are supported.
- HDMI video and many DVI (using HDMI input) formats are supported.
- Multi-link or single link SDI combinations can be used for UHD/4K.
- Most models have an HDMI output for monitoring/pass-through or for use as a composite image output (Overlay, PiP, etc.)
- Multichannel frame grabber: Multiple input models allow the use of a single card to capture multiple sources simultaneously! Limited only by bandwidth constraints it can be used for stereoscopic 3D, etc.
Auto Signal Detection
Boards of the 4Kapture family are capable to automatically detect the source, format and resolution of the video input. They are designed to automatically select the active HDMI or SDI video source. In the case of multi link SDI we will sort out the signals for you! Of course, if you want to do the selection manually the option is also available.
Software Development Kit
The 4Kapture SDK provides all the tools needed to develop applications around the 4Kapture products. The SDK has support for Windows and linux. The API remains identical over all platforms.
You can use common frameworks such as DirectShow, V4L2, or GStreamer but if you are looking for performance and rapid development you can use our own API framework. Our API is based on a client–server model. To develop your application you only need to write a simple client application (plenty of examples!) that will request the video data from the server running behind the scenes on your host. And we do most of the work for you to write recorder, streaming, display, and image capture applications.
These client application be written using common programming languages such as c/c++, golang, c#, python, etc. and can be coded in a few dozen lines or less. Sample applications are provided demonstrating the use of the API.
In addition to the Enciris API we also provide support for other generic interfaces including DirectShow and V4L2. The 4Kapture works with over 50 industry-leading capture and processing software packages
Enciris ISP (Image Signal Processing)
This unit performs adaptive de-interlacing using a special algorithm to convert interlaced images to progressive images for compression or uncompressed capture. Saw tooth effects are removed, even for high motion interlaced video, without affecting detail.
If scaling is needed, the LT3XX incorporates two scaling units that allow the user to reduce the image size. This is primarily used to reduce either or both compressed or uncompressed video bandwidth. The two scaling units can be controlled individually. The first is for the compressed video path and the second is for the uncompressed video path.
In order to have full frame rate uncompressed video data transferred to the host system it may be necessary to reduce the image size. If the size of a very high resolution image is not reduced, the acquisition frame rate will automatically drop to meet the host bus (your PC) bandwidth limitations.
The LT3XX boards family allows to change the overall tone of the video images by adjustment of hue, saturation, brightness and contrast in real-time.
The video croping unit build in the LT3xx family allows to cut out parts from the incoming video (effectively “zooming in” on the video) in real time, this feature can be used to change the aspect ratio of the incoming video prior to start the compression.
The LT3xx are compatible with x2 PCI Express standard and can be placed in any available x4 or x16 slot. Multiple cards can be placed on a single mother board for multichannel acquisition system.
On Screen Display
Text overlay is available to the compressed video path. The overlay is applied prior to compression and can be used to place a date/time stamp, watermark, or identification label.
The user can arbitrarily place four 16 character text windows within the video frame. If long strings are required, the windows can be placed side by side.
High fidelity video processing
The Enciris advanced video pipeline allows to perform the video procession without lack of quality by accepting video formats with 10 bit color depth and without Chroma Subsampling (4:4:4 10-bit)
Noise reduction filter
A pre-compression filter can be enabled to help remove noise and some high frequency components and thus improve the video compression quality. This filter may reduce some image sharpness and its usage should be determined experimentally.
Frame rate decimator
The LT1XX family has a flexible frame rate decimator that reduces the frame rate of incoming video to an arbitrary value. This is primarily used to reduce the frame rate for high resolution images to meet the requirements of the compression engine but can also be used to reduce the amount of compressed or uncompressed data. At this time there is only a single frame rate decimator unit for both the compressed and uncompressed video paths.
In 3D mode, the multichannel boards from the LT1xx can capture synchronize and mix 3D video from 3D video sources without making use of the processor resources from the host system.
Color Space Conv.
Thanks to the color space converter the LT3xx family board are able to capture videos coded in any color space. this unit is able to convert video data from YCbCr to RGB & YUV to RGB
In addition to that coefficients can be manually programed for any non standart color scheme conversion.
Low Latency Stream
The Enciris 4Kapture family of frame grabber boards use an industry-leading capture system with only a single frame of end-to-end latency when all features are enabled.
In some applications where minimising latency even further is critical, an ultra low latency mode is available. When using this mode the current frame becomes available to the host system after just 64 video lines.
