IP broadcast fundamentals

Description

IP broadcast training course description

A current hot topic in recent years has been the provision of multimedia services over IP networks aka triple or quadruple play. This course investigates the characteristics of video transmission and then studies the impact on IP networks.

What will you learn

• Use Wireshark to analyse and troubleshoot TV streams.
• Describe techniques, which can be used in IP to provide low uniform delay.
• Evaluate IPTV technologies.
• Design data networks, which will support IPTV.
