About This Chapter
Voice & Video Communication Over IP - Chapter Summary
This mobile-friendly computer science chapter offers short and simple lessons that cover the basics of voice over Internet protocol (VOIP) and video-over IP. After defining the elements of these computer communication methods, you'll take a look at their signaling and transport protocols, as well as methods that are used to assure voice and video quality. When you're finished with a lesson, try the accompanying self-assessment quiz to retain key terms and concepts. The chapter also includes an Ask the Expert feature that you can use if you have any questions. By the end of the chapter, you should be able to:
- Describe the history and functions of voice over Internet protocol (VOIP)
- Recognize the characteristics of video-over-IP
- Outline signaling and transport protocols for VOIP and video-over-IP
- Evaluate VOIP and video-over-IP quality of service assurance methods
1. What Is Voice Over Internet Protocol (VOIP)? - Definition & History
This lesson will define VOIP, explain a little about how the technology works, how it came about, and give some examples of everyday usage. Following this, you'll be able to test your newfound knowledge with a quiz.
2. Video-Over-IP: Definition & Characteristics
In this lesson, we will understand the characteristics and usage of video-over IP technology. Applications of IP video like streaming video and video conferencing are also explained.
3. Signaling Protocols for VOIP & Video-Over-IP
You probably already use VoIP or Video-over-IP for making calls over the internet, but what do you know about the signaling protocols behind them? In this lesson, you'll learn more about H.323, SIP and MGCP.
4. Transport Protocols for VOIP & Video-Over-IP
Transport protocols for video and voice over IP (VOIP) include RTP and RTCP. In this lesson, we'll define what transport protocols are and explore how real-time data is conveyed and monitored through RTP and RTCP.
5. Quality of Service Assurance for VOIP & Video-Over-IP
Voice over IP (VoIP) has quite the fascinating history and has been proven to be extremely useful over the years. This lesson will cover a brief history of VoIP and discuss the requirements needed to make it also work with video calling capabilities.
