The difference between USB3.0 capture card and USB2.0 capture card
USB video capture cards have always been the mainstream of notebook capture applications, and they are very convenient to install and use. The transmission bandwidth difference between USB2.0 and USB3.0 is very large, so USB2.0 video capture cards mainly capture analog signals, while USB3.0 video capture cards can capture high-definition VGA, HDMI, DVI, SDI and other signals, and can meet the needs of synchronous acquisition of multiple video signals.
To sum up, there are the following points:
1. The data bandwidth of USB3.0 is ten times that of USB 2.0, and the transmission speed is much higher than 2.0;
2. USB 3.0 has lower power consumption, which is about 25% lower than USB2.0 at a data transmission rate of 20MB/s;
3. USB 3.0 can provide greater power through cables, which means that devices charged through USB can complete the charging process faster under the 3.0 port.
In addition, USB 3.0 is also backward compatible with USB 2.0, and the full replacement of 2.0 is the future development trend.
Currently, Bodeyue has launched the HDU7H USB3.0 high-definition video capture card, which supports 1080P: 1-channel HD (DVI/VGA/HDMI/component/composite) + 4-channel video + 2-channel audio, while the USB2.0 video capture card VS061 has been widely used in the acquisition needs of ordinary analog video.
What are the configuration requirements of the host for the HD video capture card?
