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.

Over-the-top (OTT) video is increasingly challenging the traditional broadcast model with added convenience in terms of both user experience and reach. Thanks to a growth rate ten times that of traditional TV, OTT already accounts for 15 percent of total industry revenues and is projected to approach one-third of the market by 20221.

Timing is the most fundamental aspect of broadcast television. From the early days of tube cameras, to modern OLED displays, timing continues to play a crucial role for maintaining an optimal viewer experience. Picture stutter and breakup are just a few of the symptoms of synchronization and timing errors.
Part One of this two-part series explored the various layers and protocols of ATSC 3.0 that broadcasters must understand to take full advantage of the opportunities available through the technology. This second and final installment explores best practices for signal verification and compliance across the ATSC 3.0 ecosystem.
The Cloud itself is pretty simple, but for broadcasters, leveraging it can be complex. It isn’t that difficult technically, but Broadcast still straddles requirements that demand real time, high resolution, quick turnaround solutions; and this is coupled with the need to connect geographically separate locations, reduce costs, and extend access to assets regardless of where the data is stored with multi-format distribution capabilities.
New devices, including tablets and smartphones, enable television viewers to enjoy live sports and news anytime, anywhere, but latency remains a real issue, causing frustration amongst end-users. In today’s connected world, where viewers are simultaneously checking social media feeds on their smartphones and tablets, a significant delay means that end-users might find out about a game-winning soccer goal from Twitter before actually seeing it. With traditional unicast streaming, buffering several big chunks is necessary for avoiding service interruption with bursty and irregular http traffic. This article will explore the sources of latency in the video delivery chain and explain how multicast technology and managed network capabilities can ensure smooth traffic without requiring massive buffering on the player side to guarantee a good quality of experience (QoE). Using multicast technology and other recent technology innovations, service providers can stream live on connected devices, with ultra-low latency.
The Society of Motion Picture and Television Engineers (SMPTE), the organization whose standards work has supported more than a century of technological advances in entertainment technology, has published standards for binding Ad-IDs to commercials and Entertainment ID Registry (EIDR) codes to programming content. The standards specify use of Kantar Media’s audio watermarking technology, an open solution available for licensing and paves way for streamlined cross-platform measurement by enabling faster and more accurate tracking and audience measurement of content and ads across media
Since NAB 1995 — 23 years ago — when Rob Glaser introduced Real Audio, the first streaming media platform, the idea of media delivered over the internet has caught fire. Today, estimates are that up to 90 percent of internet users watch videos or listen to audio online. That trend has transformed media.
