High Quality Ultra-HD 18gbps Supports 4K Hdr, 3D, 2160p, 1080P, Ethernet Braided HDMI To HDMI Cable

HDMI, also known as High Definition Multimedia Interface, is a high-definition multimedia interface. This is a fully digital video and audio transmission interface that can send uncompressed audio and video signals.

HDMI can transmit uncompressed high-definition video and multi-channel audio data with high quality, with a maximum data transfer speed of 5Gbps. Meanwhile, as there is no need for digital/analog or analog-to-digital conversion before signal transmission, the highest quality audio and video signal transmission can be guaranteed.

HDMI not only meets the current highest resolution of 1080P, but also supports the most advanced digital audio formats such as DVD Audio, supporting eight channel 96kHz or stereo 192kHz digital audio transmission. And only one HDMI cable is used to connect, eliminating the need for digital audio wiring. Meanwhile, the additional space provided by the HDMI standard can be applied to future upgraded audio and video formats.

At present, HDMI interfaces are widely used in various devices, including but not limited to set-top boxes, DVD players, personal computers, televisions, game consoles, integrated amplifiers, digital speakers, and televisions.

The advantages of HDMI interface mainly include:

1. Quality: HDMI is a digital interface that can provide the best video quality. Especially at high resolutions, such as 1080p, digital videos are clearer than component videos, eliminating softness and tailing.

2. Usability: HDMI integrates video and multi-channel audio in a single cable, eliminating the cost, complexity, and confusion of using multiple cables.

3. High intelligence: HDMI supports bidirectional communication between video sources (such as DVD players) and DTVs, enabling new features such as automatic configuration and one click playback. By using HDMI, the device automatically transfers the most efficient format for connected displays (such as 480p vs 720p, 16:9 vs 4:3), eliminating the hassle of consumers having to scroll through all format options to guess the best viewing format.

4. Simplicity: HDMI cables have a simple and sturdy appearance, and are not afraid of damaging the connector pins. Compared to analog video cables, HDMI has less peripheral interference and signal noise.

However, HDMI interfaces also have some drawbacks:

1. Cost: Although the popularity of HDMI interfaces is already quite high, their cost is still relatively high compared to other connection methods.

2. Compatibility: Although the HDMI interface works well on most devices, there are still some compatibility issues. For example, some older devices may not support the HDMI interface or may require additional converters to use the HDMI interface.

3. Signal transmission distance: The signal transmission distance of HDMI interface is usually short, usually within a few meters. If transmission over longer distances is required, longer HDMI cables or additional signal amplifiers may be required.

4. Signal bandwidth limitation: Although HDMI interfaces can transmit high-quality video and audio signals, they may be limited when transmitting large amounts of data. For example, if multiple high-definition video signals or a large amount of audio data need to be transmitted simultaneously, higher-level interfaces or additional devices may be needed to process this data.
