In this lesson, we investigate important numbers that appear in the transport of audio, as well as ways of troubleshooting some common networked audio problems.
If you look at the many fields in a typical IP packet, you might find several error check fields. Why are there so many, and what is their purpose? Learn the answers to these questions and more.
While AV approaches IP-based transport from a number of angles, broadcasters have arrived at a unified solution for their similar needs. Can—and should—the AV industry follow suit?
There are a lot of key numbers associated with AV; here are two important numbers associated with IP networks that you should know and remember.
Get up to speed on HTTP, how it works, and why it’s important in AV.
A look at some Ethernet techniques, including the use of trunking to combine switch ports.
Convergence is playing out 'naturally' at West Chester University, where the AV and IT departments have been working together for many years.
A case study to apply lessons learned on protocols, addressing, standards, and how IP is used.
Maybe a task force of leaders from each of the sectors could meet periodically with a directive to address the technical issues faced by each group.
When I’ve talked with students, relatives, and friends about computer security, they often questions such as, “Why can’t the bad guys just steal the key?”
I’ve written several times about the fourth layer of the seven-layer OSI model, the transport layer.
NAT (Network Address Translation) has been used for decades by network engineers to serve two primary purposes.
I have experienced several instances where network managers or technicians have discovered two Ethernet switches connected with more than one cable.
The new approach may seem like a minor change. But almost everyone is asking the same critical question, “Do I need to change my TCP stack?”
Professionals who work with IP networks often talk about solving problems by using IP quality of service (QoS) settings.
The security of our AV devices is the leading focus of discussions in the AV industry today.
The Real-time Protocol (RTP) is one of the most widely used protocols in the AV over IP industry.
One of the most prevalent problems with IP networks occurs when IP subnet masks are incorrect.
In a recent AV industry blog, a writer stated that Biamp made a “misstep" when it chose AVB over Dante as a primary method of audio transport in their TesiraFORTÉ product line.
This IP lesson will focus on layer two switches, which are almost exclusively Ethernet switches.
