An audio and video capture card is a hardware device that can convert video signals from different signal sources (such as cameras, game consoles, etc.) into digital signals, which are then transmitted, processed and stored by computers.
Audio and video capture card solutions generally refer to hardware solutions for capturing, converting and transmitting audio and video signals to computers or other devices. Such devices are very common in the fields of video conferencing, live broadcasting, monitoring, professional video editing, etc. They can obtain audio and video signals from different sources, such as cameras, ana-log TV signals, game consoles, DVD players, etc., and convert them into digital signals for computer processing and storage. The following are the characteristics of some common audio and video capture card solutions:
1. PCI-E HD capture card:
• This capture card is connected to the computer motherboard through the PCI-E interface and is suitable for scenarios that require high-quality video capture. It usually supports higher resolutions and frame rates, such as 1080p60fps.
• The size is about 106mm x 72mm, which is easy to install in most PC cases.
2. USB3.0 capture card:
• Provides a more flexible connection method without internal installation, suitable for users with high mobility and portability requirements.
• Supports HDMI 1080P60 input, and the USB3.0 interface can provide enough bandwidth to transmit high-definition video and audio data.
• Audio and video capture follows the UAC/UVC standard, which means it can run on multiple operating systems, including Windows, Linux and Mac OS.
• The supported video sampling rate is HDMI 165MHz, the audio acquisition rate is 44.1kHz, and the output color space is YUY2 and MJPEG format.
• With the HDMI loop-out function, it means that the capture card can not only capture signals, but also output signals to another display or device, which is useful for scenes that require real-time preview.
• It also supports HDMI 1080P60 input and USB3.0 1080P60 capture, ensuring high-quality video transmission.
