AVoverIP Video Workshop


Enabling a Network for AV Communications

Video conferencing began allowing AV network traffic, but VoIP paved the way for wider acceptance of the converged network concept as a common reality. Network managers no longer say "not on my network", though are rightfully mindful of how anything impacts the mission-critical operations. We will explore a sampling of AV implementation to assure secure, effective and productive results.


Subnets and VLANs

The subnet mask is particularly confusing, especially if it isn’t the familiar In this session, we’ll look at how the mask creates a subnet and how that differs from the idea of a virtual LAN. You will see numerous examples and hear how these are useful in AV deployments.


VDP-TCP / Ports/ Adaptive Video Streaming

UDP-TCP/Ports/and forms of IP video. This session will discuss the difference between UDP and TCP, emphasizing the difference in network characteristics that support audio and video streams using the two protocols. We’ll also cover port numbers, what they mean, and their role in configuring a firewall or proxy server. finally, we’ll look at video transport platforms that use RTP, RTSP, adaptive HTTP and WebRTC and how the related to the previous topics.


IP Security Basics for AV

How are keys for encryption created and distributed? What does it mean to require a device to authenticate to the network? How secure are our AV devices? These are issues to be discussed in this session.


MPEG Transport and Multicasting

In this session, we’ll discuss the mpeg transport mechanism, the most widely used format for carrying UP video. While it was popularized for IPTV, sometimes it’s even hidden under streaming protocols used by the major vendors. Then we’ll dig into multicasting and discuss some practical concerns that seem to come up with deployments that use the mpeg transport stream. Specifically, we’ll consider some AV products that depend on mpeg transport and multicasting.
