HDMIsääntöjä

HDMIsääntöjä, also known as HDMI Cables or HDMI Standards, refer to the technical specifications and protocols that govern the transmission of audio and video data between devices using the High-Definition Multimedia Interface (HDMI) technology. HDMI is a digital interface that allows for the transmission of uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a Blu-ray player or gaming console, to a compatible display device, such as a television or monitor.

The HDMI standards are developed and maintained by the HDMI Licensing Administrator, which is a subsidiary of the Consumer Technology Association (CTA). The standards define the physical and electrical characteristics of the HDMI connectors, as well as the protocols for transmitting audio and video data. The most recent version of the HDMI standard is HDMI 2.1, which was released in 2017 and supports higher resolutions, higher refresh rates, and variable refresh rates.

HDMI cables come in various types, including standard HDMI cables, high-speed HDMI cables, and auto-switching HDMI cables. Standard HDMI cables support resolutions up to 1080p, while high-speed HDMI cables support resolutions up to 4K and higher. Auto-switching HDMI cables can automatically switch between different input sources, such as a Blu-ray player and a gaming console.

HDMI cables are widely used in consumer electronics, as they provide a simple and reliable way to connect audio and video devices. However, it is important to ensure that the HDMI cable and the connected devices are compatible with the same HDMI standard to avoid any compatibility issues. Additionally, the length of the HDMI cable can affect the quality of the transmitted audio and video data, so it is recommended to use high-quality cables and keep the cable length as short as possible.
