Managing media assets
Bernie Walsh looks at some of the considerations for designing a central storage system and the consequent technical issues that need to be addressed.
Requests for archive material into the news editing environment are often urgent.
There is also the issue of managing resources to best effect. By its nature, tape storage works best when reading or writing at its maximum data rate.
Running the tape continuously gives a better throughput, as well as less wear and tear on the tape and the drive, than starting and stopping simply because bandwidth is not available.
Content lifecycle management
The requirements of each broadcaster in terms of storage allocation, security, management, resilience and response times will be different. We have defined a central storage solution as essentially invisible to the user.
Clearly, then, it is not acceptable for the broadcaster's preferred workflow and individual requirements to be compromised by a central storage system that cannot meet them.
The approach should be to look at the lifecycle of each piece of content that the broadcaster handles, then develop rules to define how it should be handled in terms of storage and security.
The goal is to make all this possible without bottlenecks in the workflow, which compromise content delivery to critical on-air applications or risk valuable content.
A central storage management system developed with these specific requirements in mind cannot be based on a conventional IT approach.
Integrated with the highly resilient hardware configuration must be software that reflects the nature of the industry.
In particular, it has to be flexible enough to handle different types of content in different ways, to provide highly resilient storage, and access by multiple users in a timely fashion.
