Audio and video transmission refers to the process of sending sound and visual information from one location to another. This can occur through various methods, including cable networks, satellite communication, and internet streaming. The data is typically converted into digital signals, allowing for efficient and clear delivery to devices like televisions and smartphones. In modern technology, compression techniques are often used to reduce the size of audio and video files, making transmission faster and more efficient. This enables users to enjoy high-quality content with minimal delay, whether through live broadcasts or on-demand services.
