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 analog or digital, with digital transmission being more common due to its higher quality and efficiency. In video transmission, the data is often compressed to reduce the amount of bandwidth needed for transmission. This allows for smoother streaming and quicker loading times. Technologies like video codecs play a crucial role in encoding and decoding video data, ensuring that viewers receive clear and high-quality images on their devices.
