hdtv接口是什么接口

 

　　 演示机型：TCL 75v6 PRO系统版本：Android 12.0 hdtv接口是高清晰度电视接口。一般电视的接口有连接卫星接收机、DVD的莲花头音频视频接口，连接外接天线的射频接口。高档电视还有连接移动存储设备的USB接口、接收高清数字电视信号的HD接口。

　　电视的原理：

　　电视用电的方法即时传送活动的视觉图像。同电影相似，电视利用人眼的视觉残留效应显现一帧帧渐变的静止图像，形成视觉上的活动图像。电视系统发送端把景物的各个微细部分按亮度和色度转换为电信号后，顺序传送。在接收端按相应几何位置显现各微细部分的亮度和色度来重现整幅原始图像。各国电视信号扫描制式与频道宽带不完全相同，按国际无线电咨询委员会（CCIR）的建议用拉丁字母来区别。电视信号从点到面顺序取样、传送和复现是靠扫描来完成。

二者的区别：

 

　　1、HDMI接口：高清多媒体接口，可以很好地传输未经压缩的高清视频和多声道音频数据，HDMI接口的最大亮点在于只需要一条HDMI线就可以同时传输影音信号，无需在信号传送前进行转换，可以保证最高质量的影音信号传送。

　　hd接口：是一种高清数字显示接口标准，可以连接电脑和显示器，也可以连接电脑和家庭影院。通过主动或被动适配器，该接口可与传统接口（如HDMI和DVI）向后兼容。

　　The hdtv interface is a high-definition television interface. General TV interfaces include a lotus-head audio and video interface for connecting satellite receivers and DVDs, and a radio frequency interface for connecting to an external antenna. High-end TVs also have USB ports for connecting mobile storage devices and HD ports for receiving high-definition digital TV signals.

　　Principles of TV:

　　TV uses electricity to instantly transmit visual images of activity. Similar to movies, TV uses the visual residual effect of the human eye to display a still image with gradual gradation, forming a visually moving image. The transmitting end of the TV system converts each minute part of the scene into electrical signals according to the brightness and chromaticity, and then transmits them in sequence. At the receiving end, the brightness and chromaticity of each fine part are displayed according to the corresponding geometric positions to reproduce the entire original image. The TV signal scanning system and channel bandwidth are not exactly the same in various countries, and are distinguished by Latin letters according to the recommendations of the International Radio Consultative Committee (CCIR). Sequential sampling, transmission and reproduction of television signals from point to plane are accomplished by scanning.
