Automating HD

When it comes to transmitting HD, managing increased file sizes and bandwidth control are the main challenges which need to be addressed. To achieve this, multiple transmission paths between the asset management system and TX server need to be controlled and so automation systems with more sophisticated algorithms are required and hence faster processing power is required. The good news is that advances in technology in recent years means increased processing power has become more cost effective than ever before.
However, only newer material is created in HD and SD material often needs to be converted to HD, through a peripheral device such as Snell & Willcox’ Alchemist Converter for example. To manage the revised HD workflow, HD capable mixers or logo generators are coming onto the market all the time to operate in parallel and eventually replace the SD infrastructure resulting in inevitable integration challenges.
Therefore, for any automation system to maintain its longevity within the broadcast environment, it needs to be flexible enough to integrate easily with any new equipment. This flexibility will protect the broadcaster’s investment in the automation equipment purchased.
So how can this best be achieved?
Because Abit’s Present-it automation system is designed around a top-down framework with its own unique data structure, it allows the characteristics of an interfacing device to be stored. In this way, logical templates are assigned to each new physical device and any upgrade to the template is automatically reflected down to the applications interfaces. This makes any necessary changes or additions to interfaces with peripheral equipment a relatively straightforward process, future-proofing the system at the same time.
With more broadcasters now making the switch to HD, the automation required to manage the new workflow is a significant consideration. The system needs to be flexible enough to manage larger files sizes and increased bandwidth but also to easily integrate with new peripheral equipment.
Even in newer broadcast environments, systems tend to be made up of both legacy based hardware and software driven equipment and so it is necessary to select a system that can easily be adapted to a changing workflow and one which links devices seamlessly. In addition, when it comes to investing in a new automation system, broadcasters need to match plans for growth with scalable, future-proof technology for the successful development of their station.
Selecting an automation system which can achieve overall frame accurate broadcast, through the synchronisation and the utilisation of a centralised architecture with a real time operating system is key. This is because it allows each interface to operate in accordance with high level control algorithms, rather being device specific, protecting the broadcaster’s investment in HD workflow now and well into the future.
Abit itself is a privately owned, leading provider of tailor-made automation hardware and software solutions for broadcasters of all sizes. Clients include major broadcasters such as: MTV, NRK, RTL and CBC.
