What is a Video Phone? Understanding the Principles of Video Phone Technology

A visual phone is a form of communication that uses telephone lines to transmit a person's voice and images (such as half-body portraits, photographs, items, etc.) in real-time. Below, the editor introduces the principle of visual phones.

The video phone is composed of a telephone, camera equipment, television receiving and display equipment, and a controller. The telephone of the video phone is used for making calls, just like a regular telephone; the camera equipment captures the image of the user and transmits it to the other party; the television receiving and display equipment receives the image signal from the other party and displays the image on the fluorescent screen.

A video phone is essentially a simplified computer, equipped with a camera and a display. Its operation is similar to accessing the internet on a computer; it first packages the digital photo captured by the camera, then transmits it to the receiving phone, where it is decompressed and played back. Each video phone has an independent public IP address, while the local network IP addresses have not yet been implemented, which largely depends on the enhancement of the phone's features.

Above is an introduction to the principle of video phones. You can get an understanding of it. With the development of microelectronics technology, the widespread use of large-scale and ultra-large-scale integrated circuits, and the rapid development of integrated services digital networks, video phones are bound to play a significant role in future communications.
