HDMI, High Definition Multimedia Interface is a fully digital image and sound transmission interface, which can transmit uncompressed audio and video signals.
The HDMI interface can provide up to 5Gbps data transmission bandwidth, and can transmit uncompressed audio signals and high-resolution video signals. At the same time, there is no need to switch before the signal transmission, which can ensure the highest quality video and audio signal transmission. The advantage of using HDMI is: only one HDMI cable is needed to transmit video + audio signals at the same time, unlike AV or RCA multiple cables to connect; at the same time, because there is no need for digital/analog or analog/digital conversion, more High audio and video transmission quality. For consumers, HDMI technology not only provides clear picture quality, but also greatly simplifies the installation of home theater systems because the audio/video uses the same cable. The HDMI interface supports the HDCP protocol, laying a foundation for watching copyrighted HD videos.
Compared with the previous digital video interface dvi, it has an absolute advantage.
- HDMI can transmit digital video and audio signals at the same time, just use one cable, DVI can only transmit digital video signals, and transmit audio signals can only use other interfaces and cables
- HDMI can transmit high-definition digital video signals, and the video effect is better than DVI
- HDMI transmission rate is faster than DVI (higher)
- HDMI transmission distance is farther than DVI under the premise of ensuring no distortion, HDMI cable can be up to 15 meters long, and DVI can only reach 8 meters
5.HDMI interface volume is smaller than DVI
- HDMI is compatible with DVI, the video signal can be connected to the DVI interface through the conversion interface
- HDMI is used on monitors that can display both video and sound (such as LCD TVs). DVI can only be used on a single monitor.
Therefore, from any angle, HDMI cabe will gradually replace DVI and become the most common interface type in the project.
