The difference between HDMI cable and three-color cable
First of all, let's take a look at the basic definitions of "HDMI cable" and "component cable".
Color difference line: that is, the three interfaces of YPbPr on the back of the TV or DVD in our home. Because this type of line is composed of three lines, it is also called a three-color line. It is a must-have for home theaters. Transmission line.
The so-called HDMI cable is a transmission line for all-digital video and sound, which can be used to transmit audio signals and video signals without any compression (English full name is "High Definition Multimedia Interface"), and its Chinese name is "High Definition Multimedia Interface". Acronym for Clear Multimedia Interface". HDMI cables can be used for data transmission on DVD players, personal computers, video game consoles, set-top boxes, integrated amplifiers, digital audio and televisions.
Now that digital lines are all the rage, analog lines are almost on the verge of being eliminated.
1. The biggest difference between the HDMI cable and the component cable is that the output of the HDMI cable is a digital signal, and the output of the component cable is an analog signal. The digital signal is not lost during the transmission process, and the analog signal is easily interfered by external and internal factors. Signal loss affects the final picture quality.
HDMI can transmit uncompressed high-definition video and multi-channel audio data with high quality, meeting the current highest resolution of 1080P, while the analog signal output by the component cable supports a maximum screen of 480P, which is the display effect of ordinary DVD players.
With the development of high technology, digitization has penetrated into people's lives. Now some high-definition players have begun to remove the color difference line. In a sense, removing the component interface may lose some users of old-fashioned TVs, but the component cable only supports 480P at the highest, which is not considered high-definition. It is a waste to buy a high-definition player and use component difference to connect to the TV. . In fact, removing the interface of the component cable has many advantages for the high-definition player. From the manufacturer's point of view, the cost of removing the component interface will be reduced, and the final price will naturally be cheaper.
2. The model can be made thinner and easier to place. Unlike high-definition players with color difference lines, the manufactured models are relatively thick. From the perspective of the playback picture, the quality of the picture displayed by the component cable is far inferior to that of the HDMI cable. And most of the users don’t need these color difference lines, they just feel more comfortable with multiple things. I believe few people buy high-definition players to connect color difference. There are also very few.
Another point is that the current length of the HDMI cable can be 15 meters long without affecting the quality of the picture, which greatly facilitates the needs of users, but the color difference line can only be about 5 meters at most without affecting the quality of the picture. If it exceeds this The range will affect the quality of the picture. Therefore, in the future, there will be more and more high-definition players with only HDMI ports, and the component cable will gradually be eliminated. As an upgrade to an old machine, you should choose a model with a component port now, otherwise the TV will be upgraded in the future.
