audio and video signal transmission

Audio and video signal transmission involves sending information—sound and images—from a source to a device like a TV or speaker. These signals are encoded into electrical or optical signals that carry the data’s details. Transmission can occur through cables (like HDMI or Ethernet) or wirelessly (Wi-Fi, Bluetooth). The receiver then decodes these signals back into the original audio and visual content. Proper synchronization and signal quality are essential for clear sound and sharp images. This process enables real-time communication and entertainment over short or long distances efficiently.
