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…
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…
Podcasts are taking the world by storm. It is hard to believe that when audio-over-internet technology was revealed at NAB, 1995, that it would grow so fast and become so profitable to such a wide range of people.
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…
There are many more curators of solutions in the pay-TV market now that there is a move to an all IP infrastructure away from traditional broadcast. Aside from voice, the underlying technologies in pay-TV remain the same as they have for some years i.e. Linux, JavaScript, HTML5, SQL databases…
A few months ago, I switched my main landline phone number to my iPhone. In doing this, I did not consider the issue of recording interviews from incoming and outgoing calls — something that’s easier said than done with an iPhone. This is how I mastered the issue.
Weather can change on a dime. Whether it is extreme heat or cold, rain, snow, thunderstorms, hurricanes, tornadoes or wild fires, video crews must be prepared for any kind of foul weather.
Certain high-end professional audio recorders have options for either WAV, WAV Mono and WAV Poly (polyphonic) files. What’s the difference and what should your choice be?
The bewildering number of video and audio compression formats available is difficult for those new to the industry to come to terms with. For broadcast engineers and IT engineers to work effectively together, IT engineers must understand the formats used, the legacy systems still in place, and the reasoning behind…
Point to point connections dedicated to delivering video and audio signals have dominated the broadcast industry since the 1930’s. But migrating to IP is compelling engineers to think differently about packetized signal distribution. In this article we investigate the potential sources of congestion and the effects of buffering.
