Multi-channel high-definition VGA video capture card
The multi-channel high-definition video capture card uses ADI's ADC chip and integrates large-capacity 64-bit width DDR2 onboard storage, so that it does not occupy the host CPU during the capture process, and the video restoration color is more high-definition and lifelike. This high-performance capture card integrates one VGA signal input, two D1 video inputs, and one audio input in a single card. The built-in software can realize 6-channel signal collection and compression, with high image quality, low cost and low power consumption.
1. Multiple input channels: 1 high-definition VGA input, 2 high-definition CVBS Video signal inputs, 1 audio signal input
2. High-speed PCI-E slot: Using PCI-E 1x slot, the transmission bandwidth is twice that of PCI bus slot
3. Advantages of 1-channel VGA signal collection:
→ Large input bandwidth: 230MHz
→Scan mode: progressive scan mode
→Large progressive scan resolution support: 1920 x 1440 x60HZ
→Acquisition format: RGB16, RGB24, RGB32, YUY2
→Multiple output formats: RGB565, RGB24, RGB32, YUY2, UYVY
→Tested VGA acquisition performance: 1600x1200x85Hz, RGB24: 30fps. 1280x1024x85Hz, RGB24:45fps. 1024x768x85Hz, RGB24: 80fps
→Support VGA display mode: support any resolution under 1920 x 1440, including unconventional resolutions, automatically identify and display
4. Advantages of 2-channel CVBS signal acquisition:
→Input standard: PAL, NTSC two video formats
→Capture large format: PAL: 720x576 25fps, UYVY color format. NTSC: 720x480 30fps, UYVY color format
5. Audio input advantages:
→Sampling frequency: 8/16/22.05/32/44.1 KHz
→Sampling precision: 24 bit
→Signal-to-noise ratio: >= 85 db
→Number of channels: 2 Channel
6. Does not occupy the host CPU: Using the efficient Master DMA mode, the image acquisition process does not occupy the machine CPU
7. Storage bandwidth 2GB/s: using 256MB/64bit DDR2 memory chip as image cache
This VGA capture card can record up to 6 channels of video at the same time. The recording formats include rms and HTML courseware. It can be used in situations such as teacher evaluation, courseware production, network streaming live broadcast, video conferencing and other occasions that require simultaneous recording of multiple scenes.
