A White Paper from Media Links
Huge quantities of ink and pixels have been spent extolling the virtues of an all-IP infrastructure for a modern media production facility such as a broadcast studio or and IPTV head-end. Today, Media Links is one of the only companies in the world that has successfully installed complete, IP-based studio systems for global clients. By integrating all of the video, audio and data flows onto a common platform, huge up-front savings and continuing cost reductions can be realized.
The primary advantage of an IP-based system is the convergence of multiple signal formats onto a comprehensive, distributed IP switch fabric that seamlessly transports kilobit-speed data signals alongside multigigabit uncompressed video flows. Media production facilities benefit by not having to purchase, install, manage, or maintain the multiple signal routing systems that are normally required to switch different types of compressed and uncompressed audio. A converged IP backbone dramatically increases system flexibility, allowing new applications, bit rates, and signal formats to be added to the core switching platform merely by adding a new type of interface card.
Today’s smartphone owners carry more powerful video technology in their pockets than the best state-of-the-art TV broadcast or production facilities could provide two decades ago at any price. The second decade of this century is when off-the-shelf computing matures to the point that it can facilitate and manage nearly all technology-based tasks in broadcast TV stations and TV networks in real-time.
Engineers face new challenges in measuring 12G-SDI signals, which require different techniques compared to those used with SD-SDI, HD-SDI and 3G-SDI signals. Here we will touch on the importance of signal shape, the impact of jitter and the complexities of the different interface formats.
Video over HDMI has proven for more than a decade it has a place in professional and broadcast TV infrastructures and its use continues to grow. Will HDMI replace the SDI interface?
Interest is growing in the broadcast industry about the AES67 standard, and its potential benefits as users transition from wired to networked audio systems.
The Media Networking Alliance has issued a maintenance revision to AES67-2013, the AES standard for high-performance streaming audio-over-IP interoperability.
As the size of video files explode in size, it’s too expensive to keep building larger capacity distribution pipes. For that reason, the race to improve video compression technology has taken center stage. The only question today is how efficient can compression get?
The amount of video coming down the track for carriage over mobile is threatening to break the net unless encoding vendors and compression standards can keep pace. The lesson from a recent IBC panel is that this can happen - provided the industry pays for it.
