The main video interface features of Tenveo videoconferencing camera knowledge point

There are many interfaces widely used in videoconferencing camera devices, including CVBS interface, S-Video interface, YPbPr/YCbCr color difference interface, DIV interface, and HD-SDI interface.

1. Composite Video Interface (CVBS)

The composite video interface is used for the connection of standard definition analog video signals between video devices. The composite video interface, also called AV interface or Video interface, is a commonly used analog video interface.

2, S-Video interface

The S-Video interface is a common video interface. S stands for Separate. Compared with the composite video interface, it transmits luminance and chrominance separately, and does not perform mixed transmission of luminance and chrominance models, thereby avoiding the output of mixed video signals. The image distortion caused by the mutual interference between the luminance signal and the chroma signal greatly improves the sharpness of the image.

3, YPbPr/YCbCr color difference interface

YPbPr/YCbCr color difference interface is based on the S-Video interface, the color difference signal in the chroma signal is transmitted separately, where YPbPr represents the progressive color difference output, YCbCr represents the interlaced color difference output.

4, DVI interface

DVI interface and VGA interface are the most common interfaces in the computer. Because the computer transmits binary digital signals internally, if you use a VGA interface to connect the LCD display, you need to first convert the signal through the D/A converter of the graphics card to R/. G/B three primary color signals and line and field synchronization signals. These signals are transmitted to the liquid crystal display through analog signal lines. The corresponding A/D converters are required to convert the analog signals into digital signals again.

5, HD-SDI interface

The SDI interface is a "digital component serial interface" which transmits the data brother's brother bits sequentially through a single channel. The HD-SDI interface is a broadcast-grade, high-definition digital input and output port, where HD represents the HD signal. In non-editing post-production, HD-SDI is widely used in broadcasting and other fields.

6, HDMI interface

HDMI interface Chinese means high-definition multimedia interface. The HDMI interface can provide up to 5 Gbps of data transmission bandwidth and can deliver audio signals and HD video signals that have not passed through Yasso. It also features plug and play.
