Voice and Video Conferencing Fundamentals
Design, develop, select, deploy, and support advanced IP-based audio and
video conferencing systems
The authors begin with a clear, concise overview of current voice and
video conferencing, including system components, operational modes,
endpoints, features, and user interactivity. Next, they illuminate
conferencing architectures, offering practical insights for designing
today's complex IP-based conferencing and collaboration systems.
Topics covered in this book include video codecs, media control, SIP and
H.323 protocols and applications, lip synchronization in video
conferencing, security, and much more. Throughout the book, the authors
draw on their extensive experience as Cisco® technical leaders, showing
how to avoid the most common pitfalls that arise in planning,
deployment, and administration.
Voice and Video Conferencing Fundamentals is for every professional
involved with audio or video conferencing: network and system
administrators, engineers, technology managers, and Cisco solution
partners alike. Whether you're involved with design, development,
selection, implementation, management, or support, you'll find the
in-depth knowledge you need to succeed.
