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.
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.

There are many types of codecs, all used for specific purposes to reduce file sizes and make them easier to distribute down a limited bandwidth pipe. Lossy compression and Lossless compression are the two most common categories of data compression used to reduce the size of data without significant loss of information.
OTT has dramatically expanded the range of delivery outlets for content and continues to do so. This has had a direct effect on content production, enabling almost any organization or person to create and distribute live content, which has increased the volume of content being created. Whether this content is for entertainment, news, education or communications, video is our preferred communication medium and people generally turn to this whenever possible.
PTP - as a precise network timing technology has been available for nearly two decades. It is already widely used in Telecommunication networks, Finance and Trading platforms, substation automation networks and many more industries. Every industry has its own demands such as target accuracy on the end nodes, or whether it should be used locally or via wide area connections. Furthermore, there is often the question of whether existing network components should be re-used or if they will be replaced.
