Understanding how to make different vendors software operate coherently is critical to achieving the smooth operation of real-time broadcast facilities, especially with the new emergence of IP infrastructures. Discover who is achieving this and how.
The concept of working from home was trending long before public health issues caused most of us to contribute remotely, but the past year has seen an acceleration no one could have predicted. What those in the media industry quickly learned is that it’s not that easy to take your work home with you.
Telco fixed access networks are “the last mile” to homes and commercial buildings. They play a key role in the delivery of OTT Video, and are undergoing big changes to support its growth. Telco fixed access networks were originally built in the 19th century to deliver telegraph services, evolving during the 20th century into telephone services. Today they provide vital telecommunications services supporting all aspects of a nation’s life including government, business, education and entertainment. Companies in this sector include the likes of British Telecom, Telecom Italia and AT&T. Over the last 30 years, the voice-first PSTN network has evolved to support data services over broadband, and today telco’s are deploying new data-first access networks.
While many professionals have come to understand how to configure IP-based infrastructures to handle the distribution of audio and video files, managing specific devices on the network has been extremely complex, at best. Recognizing this, Lawo has developed a new software management platform called Home that makes it easy to set up, manage and benefit from the flexibility, scalable nature and signal-agnostic design that comes with IP infrastructures.
A group of international technology vendors and broadcasters is working on developing and implementing Artificial Intelligence (AI) standards to improve video coding. Calling itself MPAI (Moving Picture, Audio and Data Coding by Artificial Intelligence) they believe that machine learning can improve efficiency of the existing Enhanced Video Coding standard by about 25 percent.
Complex workflows often involve diverse teams of partners and collaborators exchanging files in the fastest time possible. FTP no longer delivers the speed and operational simplification needed so we must now turn to acceleration technology geared towards media file transfer to meet the demands of modern media workflows.
In the UK we have Oxford v Cambridge. In the USA it’s Princeton v Harvard. The only difference is that one is a boat race and the other is computer architecture race.
Video, audio and metadata monitoring in the IP domain requires different parameter checking than is typically available from the mainstream monitoring tools found in IT. The contents of the data payload are less predictable and packet distribution more tightly defined leading to the need to use specialist media stream centric monitoring tools.
In this article, George Kroon, research broadcast engineer, takes a look at how Negative ARQ protocols similar to those used for internet streaming and contribution can be improved specifically for broadcast television.
