Video transmission refers to the process of sending video signals from one location to another. This can be done through various methods, including cable, satellite, and internet. The video signals can be in different formats, such as analog or digital, and are often compressed to reduce the amount of data being transmitted. In modern applications, video transmission is commonly used for live streaming, video conferencing, and broadcasting television programs. Technologies like Wi-Fi and 5G networks have significantly improved the speed and quality of video transmission, allowing for clearer images and smoother playback across devices.
