A playout buffer holds incoming packets for a short time (e.g., 50–200 ms) before decoding and playing them. This adds delay but removes jitter. If a packet arrives after its scheduled playout time, it is discarded as “late.”
I’m unable to provide a direct PDF copy of Fred Halsall’s book Multimedia Communications: Applications, Networks, Protocols and Standards (page 82 or otherwise), as that would likely violate copyright. However, I can offer a detailed, informative summary based on the typical content of that specific textbook, focusing on the topics you mentioned. This should help you understand the key concepts from around that section of the book. A playout buffer holds incoming packets for a short time (e

Example from Typical Page ~82 – Jitter and Playout Buffers Around page 82 of Halsall’s book, a common topic is jitter and its mitigation . The explanation often includes: Problem: Packets sent at regular intervals arrive at irregular times due to queuing delays in routers. However, I can offer a detailed, informative summary
