Byte-Sized Lesson in AV/IP: IP Numbers in Audio By Phil Hippensteel 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.
Byte-Sized Lesson in AV/IP: Errors in IP Networks By Phil Hippensteel 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.
What the AV Industry Can Learn From SMPTE 2110 By Phil Hippensteel 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?
Byte-Sized Lesson: Two IP Numbers You Should Know By Phil Hippensteel 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.
Byte-Sized Lesson: HTTP By Phil Hippensteel Get up to speed on HTTP, how it works, and why it’s important in AV.

WCU’s Kassabian on Building AV/IT Departmental Synergy By Phil Hippensteel Convergence is playing out 'naturally' at West Chester University, where the AV and IT departments have been working together for many years.
Byte-Sized Lesson: Troubleshooting Study By Phil Hippensteel A case study to apply lessons learned on protocols, addressing, standards, and how IP is used.
Standards Problems as AV and IT Merge By Phil Hippensteel 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.
Byte-Sized Lesson in AV/IP: Security’s Magic Numbers By Phil Hippensteel 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?”
Byte-Sized Lesson in AV/IP: Critical Layer Four By Phil Hippensteel I’ve written several times about the fourth layer of the seven-layer OSI model, the transport layer.
Byte-Sized Lesson in AV/IP: Network Address Translation By Phil Hippensteel NAT (Network Address Translation) has been used for decades by network engineers to serve two primary purposes.

Google Wants to Change TCP. Will It Affect AV/IT Stakeholders? By Phil Hippensteel 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?”
Byte-Sized Lesson in AV/IP: QoS By Phil Hippensteel Professionals who work with IP networks often talk about solving problems by using IP quality of service (QoS) settings.
Byte-Sized Lesson In IP/AV: Security of AV Devices On The Network By Phil Hippensteel The security of our AV devices is the leading focus of discussions in the AV industry today.
Byte-Sized Lesson in AV/IP: Real-Time Protocol (RTP) By Phil Hippensteel The Real-time Protocol (RTP) is one of the most widely used protocols in the AV over IP industry.
Byte-Sized Lesson in AV/IP: Mismatched Subnet Mask Issues By Phil Hippensteel One of the most prevalent problems with IP networks occurs when IP subnet masks are incorrect.
AVB: Biamp’s Smart Move By Phil Hippensteel 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.
Byte-Sized Lesson In AV/IP: L2 Switches/VLANs By Phil Hippensteel This IP lesson will focus on layer two switches, which are almost exclusively Ethernet switches.
