JPEG 2000 over IP
Last month, we talked about Ethernet and IP and the advantages of a layered network stack. Let’s look at an application that uses these layers — the streaming of JPEG 2000 over IP.
Ethernet and IP
Ethernet and IP are terms broadcast engineers use many times every day. But what, exactly, is the difference between the two? Both on the OSI hierarchy, their difference is in layers.
MXF and AAF
Many broadcasters know about MXF, and they have heard of things such as MXF for Finished Programs (AS-03) and MXF for Commercials (AS-12). But, this month, I want to focus on MXF’s bigger brother, AAF.
Router fundamentals you should know
Routers are core to broadcast networks. So, I want to introduce some fundamental concepts regarding networking that may help you understand how routers work.
Ethernet
Ethernet is both a protocol and a hardware specification. The Ethernet specification details electrical signals and voltages on the wire (or the RF transmission scheme in the case of wireless), and it lays out how
System administration for broadcasters
When professional media systems are delivered, they frequently contain computers and servers, and before we know it, because we installed them and we maintain them, we are the go-to guys and gals for all things computer-related. There are several problems with having computer system administration sneak up on you:
Securing content
In the professional media industry, one fact is clear: Everything we do is about getting content to viewers, wherever they may be. The end goal, of course, is to make money off of this transaction. Clearly, if we do not have content or our content is compromised in some way, then this transaction breaks down, with serious financial consequences for the media companies involved.
Metadata and MXF, part 2
Last month in this column, we looked at the importance of metadata to the professional media industry. We talked about different types of metadata (static and dynamic, technical and descriptive), and discussed the importance of the Unique Media Identifier (UMID) and how it links metadata and content.
Metadata and MXF, part 1
This month, we will begin a two-part series on metadata and MXF. First, we will look at the importance of metadata to the professional media facility.
Network protocols
There is a core set of protocols critical to the operation of computer networks. Some of the most important protocols include IP, Transmission Control
Monitoring IP networks
IP networks have become a mission-critical part of just about every broadcaster's facility. Broadcasters need to monitor these networks with the same
Network addressing
Every engineer working with media these days should understand the basics of network addressing, and most of them do. But, network addressing is one of
