What are the advantages of HD HDMI video capture card interface?

In today's high-tech modernization, the application of high-resolution video is increasing. The emergence of broadband network video, real-time streaming media communication, large-capacity file transmission, and storage area networks has made users more and more demanding for high-quality video signals.

High-definition, high-quality, uncompressed audio and video signal transmissions are increasingly demanding network bandwidth. With the development of broadband networks, high-definition and even ultra-high-definition video signals are gradually favored by consumers. This high-definition, ultra-high-definition video signal transmission must have a corresponding video interface ------- HDMI.

Since high-resolution video signals rely on HDMI interface transmission, what are the advantages of HDMI video interface?

1.Transmission broadband is high

The HDMI interface provides up to 5 Gbps of data transmission bandwidth for uncompressed audio signals and high-resolution video signals.

2.High resolution

HDMI is a high-definition digital interface that provides the best video signal since all analog connections (such as component video or S-video) require no loss when converting from analog to digital. The difference is in high resolution, such as 1080p. Digital video will be sharper than component video, eliminating the softness and smearing found in component video, and the tiny, high-contrast details such as text take the difference to the limit. Now 2K, 4K TV sets are already very common. Everyone can watch a clearer and more detailed picture through the network device.

3.Audio and video signal synchronization

Fully digital video and audio transmission interface for uncompressed audio and video signals. HDMI supports standard, enhanced or high definition video and multichannel digital audio on a single cable. It transmits all ATSCHDTV standards and supports 8-channel, 192kHz, uncompressed digital audio and existing compression formats (such as DolbyDigital and DTS). HDMI1.3 also adds new non-destructive digital audio formats to Dolby? TrueHD and DTS-HDMasterAudio. Support, free bandwidth for future enhancements and needs. The HDMI interface is an interface that supports industrial, uncompressed, all-digital video and audio. As the latest international standard digital interface, HDMI provides an interface between video/audio sources, such as set-top boxes, DVD players, or an A/V receiver or monitor interface, such as digital TV.

4.Expansion and ease of use

HDMI and DVI can be directly transposed by adapters, and they are all digital signals. There is no signal loss in the conversion, so HDMI and DVI display devices, including video source devices, are interchangeable.

5.Confidentiality

In order to ensure that high-definition signals transmitted by HDMI or DVI are not illegally recorded, high-bandwidth digital content protection technology, namely HDCP technology, has emerged. The HDCP specification is led by Intel. When the user makes an illegal copy, the technology interferes and reduces the quality of the copied image, thereby protecting the content. Video capture card
