Isochronous channels are communication pathways that transmit data at consistent time intervals. This ensures that data packets arrive at their destination at regular intervals, which is crucial for applications requiring real-time data delivery, such as audio and video streaming. These channels are often used in systems like USB and FireWire, where maintaining a steady flow of information is essential. By prioritizing timing over error correction, isochronous channels can provide a smooth experience for users, making them ideal for multimedia applications where delays can disrupt performance.
