Dick puts it all together
Dick Hobbs. Many of you will be reading this as you prepare for IBC. Some may even be reading it on the train/plane/ship to Amsterdam. I want to take a couple of minutes of your time to look at a last minute addition to IBC. It concerns IP, but trust me: this is good news so please do not stop reading just yet.

The importance of maintaining digital audio paths
Larry Schindel A portable, handheld, digital audio stream analyzer/generator is an essential piece of test equipment in the broadcast environment. It allows engineers and system integrators to quickly monitor and verify the composition, and integrity of, audio signals at any point from production all the way through the distribution chain.
