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.
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 their existence. In this article, from the series Broadcast for IT, we investigate compression formats.
Audio is arguably the most complex aspect of broadcast television. The human auditory systems are extremely sensitive to distortion and noise. For IT engineers to progress in broadcast television they must understand the sampling rates and formats of sound, and in this article, we delve into digital audio.
At the 2018 IBC show, in addition to many other new features for both systems, Phabrix will highlight its support for SMPTE ST 2110 within its Qx series and the portable Sx TAG.
In this series of articles, we will explain broadcasting for IT engineers. Television is an illusion, there are no moving pictures and todays broadcast formats are heavily dependent on decisions engineers made in the 1930’s and 1940’s, and in this article, we investigate microphones and how they are used in television.
A total of 28 games will be covered in 4K, up to and including the final on July 15. UHD transmissions are being carried by a number of broadcasters and telco providers on dedicated 4K feeds as well as via satellite.
