Moving from the luxury of dedicated point-to-point connectivity in favor of asynchronous, shared, and unpredictable IP networks may seem like we’re making life unnecessarily difficult for ourselves. However, there are compelling reasons to make the transition to IP. In this article, we look at the primary motivation for moving to IP and the benefits it provides for broadcasters.
The SMPTE (Society of Motion Picture and Television Engineers) has responded to demand for faster development of key standards aligned with emerging business processes by establishing its Technical Specification process.
Audio can be edited these days on virtually any personal computer. Professionals, however, need to understand storage drives in order to get the best results. Here’s what to look for when buying drives for audio editing.

Low latency networks and non-blocking switches are terms now appearing in mainstream broadcasting. But what do they mean? Why are they relevant? And how do we make Video over IP work?
Everyone knows what standards converters do, right? Broadcast professionals recognize that changing the video format and frame rate is necessary when sharing materials internationally or when integrating movies into TV schedules. In fact, there are many types of standards conversion available. Here is a guide to understanding the options.
It is time to implement IP based bidirectional and multi-user radio systems in the licensed BAS band channels. The resulting improvements in data rates and new technology can enable workflows in the field much like those enjoyed in the studio. However, careful management of data rates, traffic priorities and security are required to ensure high quality signals are delivered back to the studio.
Quality Control is one of the many areas where IT and broadcast use similar terms, but the meaning is quite different. Whereas IT focuses on guaranteeing bit rates and packet delivery to improve quality of service and hence quality of experience, video and audio quality is based on satisfying the demands of the human visual and auditory systems. In this article, we investigate how we quantify and measure video and audio streams.

Many engineers believed that the release of SMPTE2110 was sufficient to ensure compatibility for all the gear in a media IP-centric environment. Not so, the standard defines the transport layer only. Complying with ST2110 will only guarantee a signal will pass through a compliant network and can be decoded by a compliant device. It doesn’t specify the IP addressing schemes, multicasting schemes, codec types, bit rates, formats, etc. Currently, all these parameters for each device must be manually configured, making automation difficult. Enter NMOS.
