Audio/Video Transport Protocols are essential for transmitting audio and video data over networks. They ensure that media streams are delivered efficiently and reliably, allowing for smooth playback. Common protocols include Real-time Transport Protocol (RTP) and User Datagram Protocol (UDP), which help manage the timing and order of data packets. These protocols are crucial for applications like video conferencing and streaming services, where real-time communication is necessary. They handle issues such as packet loss and delay, ensuring that users experience minimal interruptions. By optimizing the delivery of multimedia content, these protocols enhance overall user experience.
