Comparison of two audio and video transmission methods [Copy link]

There are two types of audio and video transmission: one is to use HDMI and other cables to transmit, and the other is to use wireless audio and video transmitters to wirelessly transmit the content on the remote playback device to the TV or projector. Which of these two methods is better? People have different opinions. After comparing and experiencing, Baibaocheng Audio and Video got the answer. First, let's learn about wired transmission. The wired transmission medium refers to the physical connection between two communication devices, which transmits the signal from the playback device to the display device. Everyone knows the connection method, which is to use HDMI or VGA cables to connect the Blu-ray player (computer) and the TV (projector). The wireless transmission method is very different from the above. Wireless transmission does not require wiring, and its transmission medium is microwave. But it needs to be realized with the help of special equipment, that is, it needs to use wireless audio and video transmitters to realize audio and video transmission. Generally, wireless audio and video transmitters are divided into transmitters and receivers. The transmitter is connected to the computer (Blu-ray player, etc.), and the receiver is connected to the TV or projector. Based on the characteristics of the two transmission methods, we can see the shortcomings of wire transmission. For wire transmission, obviously the first thing to solve is the wiring problem. Try to think about it, if your projector is installed on the ceiling, is it difficult to wire it? You can't just hang a wire down, right? If you have a wireless audio and video transmitter, many problems will be solved. The transmitter of the wireless audio and video transmitter is connected to the playback device (computer), and the receiver is connected to the display device (projector). After market research and analysis, the author found that with the development of wireless transmission technology, more and more people are keen on wireless transmission. Wireless transmission has the following advantages: easy to use, plug and play, no need to install plug-ins; no wiring, low comprehensive cost, more stable performance, only one-time investment, and wiring, decoration and maintenance are very troublesome. Therefore, between wired transmission and wireless transmission of audio and video, I prefer wireless transmission, which has good transmission effect and is easy to use.
