HD video converter is a high-tech audio and video device, which is a device that has been expanded with the development of audio and video technology. It is different from the software video format converter. It is aimed at the currently widely used VGA video interface, HDMI high-definition digital interface, SDI digital serial interface, DVI and other audio and video interfaces. Because different interface technologies are different, they cannot be directly connected, so it is necessary to expand the HD video converter.
The types of video interfaces supported by HD video converters are varied, mainly depending on the specific model and function of the converter. The following are some common types of video interfaces supported by HD video converters:
1. HDMI interface
HDMI (High-Definition Multimedia Interface): It is one of the most mainstream HD video interfaces and can transmit video and audio signals at the same time. HDMI interface is widely used in TVs, monitors, projectors, Blu-ray players, game consoles and other devices.
2. VGA interface
VGA (Video Graphics Array): It is a computer display standard interface using analog signals and adopts a 15-pin pin structure. Although the VGA interface is gradually reduced on new models of computers and monitors, it is still widely used in some old devices.
3. DVI interface
DVI (Digital Visual Interface): a digital video interface based on TMDS (Transition Minimized Differential Signaling) conversion minimum differential signal technology. DVI interfaces are divided into three types: DVI-A (analog), DVI-D (digital) and DVI-I (integrated), of which DVI-D and DVI-I are common types in high-definition video converters.
4. AV interface
AV interface: including Composite (composite video), S-Video (S terminal) and Component (component video) and other types. These interfaces are mainly used to connect old game consoles, DVD players, video recorders and other devices. AV to HDMI converters can convert these analog video signals into HDMI digital signals to meet the needs of modern high-definition televisions.
5. Other interfaces
DisplayPort (DP): a digital video interface standard developed by a coalition of PC manufacturers and chip manufacturers, with the advantages of high-speed transmission and high bandwidth. Some high-end high-definition video converters support HDMI to DisplayPort conversion.
USB interface: Although the USB interface is mainly used for data transmission and charging, some special converters (such as HDMI to USB video capturer) can convert HDMI video signals into USB data signals for recording or live streaming on a computer.
Notes
Compatibility: When purchasing an HD video converter, you need to make sure it supports the required video interface type and signal format. Converters of different models and brands may support different interface types.
Conversion quality: Due to the differences in signal types and transmission methods between different interfaces, there may be some signal loss during the conversion process. In order to obtain better conversion quality, it is recommended to choose a well-known brand and high-quality HD video converter.
Power supply requirements: Some HD video converters may require external power supply to work properly. You need to pay attention to the power supply requirements of the converter when purchasing, and ensure that there is sufficient power supply.
