Almost all the network traffic in the world these days is Transmission Control Protocol/Internet Protocol (TCP/IP) over Ethernet. From a practical standpoint,

When I started working at a CBS facility many years ago, part of my job for four hours each day was network monitoring. It was not very exciting, but

Network addressing is fundamental to all networked professional video facilities, so it is important to have a solid understanding of how it works.

Error correction and error concealment seem straightforward; error correction corrects errors, and error concealment conceals errors. But the topic is

Five years ago, file-based content delivery was making inroads with broadcasters, but it was still a somewhat unusual way to deliver video. Now, file-based

Broadcasters are becoming more dependent on their IT-based infrastructures every day. It is increasingly important to have a solid network to support

The standard for wireless networking, written and maintained by the IEEE, is 802.11. The document has been expanded over the years, and the two most heavily

Understand these five issues related to moving video over packetized networks

Frequently, I have talked in this column about separating the broadcast core computer networks from business networks and the Internet. In the real world,

The area of software design is a shifting landscape, and smart computer people are always coming up with better ways to do things. A significant shift

Firewalls can help reduce the threat of exposed networks.

Broadcasters spend a lot of time researching storage these days and with good reason. The conversion to digital and the ever-increasing number of computer

Distributing Internet content is fundamentally different from traditional linear broadcasting in several ways.

Software architectures can have a big effect on facility design, especially for broadcasters. Anytime applications work with video, it is important to

Computer engineers learn early on that a core set of protocols are critical to networks. Some of the most important protocols include Internet Protocol

Networked professional A/V applications need bandwidth and lots of it. It is no surprise, therefore, that we are always pushing the limits of networking

MAC addresses get packets to their proper destinations.

This month we are going to look at how Fibre Channel and Ethernet can be used together in the broadcast facility. Sometimes this discussion is cast as

The author examines the layered approach to networking

By now you probably have heard of the Material eXchange Format (MXF), and if you haven't already heard about the Broadcast Exchange Format (BXF), you

You are probably familiar with Ethernet technology and what it takes to put a network together. It is pretty basic stuff really. You buy a switch or two,

Metadata has been a popular topic for several years, but in many cases, the discussions have fallen short. Frequently, the topic of preserving metadata
