摘要
随着高画质影音需求增加,高速显示数据接口技术随着VR技术、游戏、影音等消费产业快速发展而更新迭代。主流的高速显示接口数据接口技术有很多种,其中高清多媒体接口(high definition multimedia interface,HDMI)的最小化传输差分信号(time minimized differential signal,TMDS)技术的抗干扰性能、兼容性以及高质量的视频和音频传输的优势,使HDMI技术成为最广泛应用的高速数据接口技术之一。HDMI 2.1实现了4K@120 Hz、8K@60 Hz和10k@60 Hz等超高分辨率和刷新率的无损影视传输,随着集成电路技术进步,HDMI接口将成为消费级高速显示数据接口关键技术。介绍了HDMI接口技术、发展历程,及其国内外发展现状,为国内HDMI产业的发展提供参考。
With the increase in demand for high-definition audio and video,high-speed display data interface technology has been updated and iterated with the rapid development of consumer technologies such as VR technology,games,audio and video.There are many mainstream high-speed display interface data interface technologies,among which the anti-jamming performance and compatibility of HDMI TMDS technology and the advantages of high-quality video and audio transmission,HDMI technology has become one of the most widely used high-speed data interface technologies.The existing HDMI 2.1 technology has realized the lossless video transmission of ultra-high resolution and refresh rate such as 4K@120,8K@60Hz and 10k@60Hz.With the advancement of integrated circuit technology,the HDMI interface will become the key to the consumer-level high-speed display data interface technology.The HDMI interface technology,development process,and its domestic and foreign development status are introduced,which providing reference for the development of the domestic HDMI industry.
