Service Orientated Architecture In Newsrooms
By Ed Casaccia, Senior Marketing Director, Grass Valley
Probably the first place any broadcast organisation saw mainstream use of computers was in the newsroom, as editorial systems have been around for 25 years or more. More recently we have seen file based production added to the scene. The next challenge is to bring the two together in a single coherent system. The suggestion to bring them together in a single system is gaining weight, and the logic behind this appears sound at first blush. But, the temptation to simply bundle everything we have today into one big application must be resisted, for two reasons. First, putting everything together into one system just creates one big single point of failure. That is more likely because a combined system is going to be bloated, placing a big drain on resources, and very difficult to manage in terms of data bandwidth. The second concern I have is that putting all the tools everywhere makes it complicated to operate, with the risk that individuals may find themselves in an unfamiliar part of the interface. There is also the risk that users may go off and explore different parts of the system, ending up with a beautifully crafted report that is delivered some hours after the programme has been broadcast. Newsrooms have a clear organisation at the human level – reporters, editors, programme directors and so on – and it makes sense to reflect that in the technology. The newsroom computer system already does this, giving the journalist scripting and research facilities, the programme director the running order, and so on. What I propose is that the newsroom computer should remain as the cornerstone of the workflow, with the additional functionality for audio and video production provided, as needed, as plug-ins. That keeps everything simple, and most important it keeps each individual workstation operating efficiently without wasting processor cycles on software it does not need. This is the essence of the service oriented architecture (SOA) as it has been used in the IT industry for many years. By making functionality available only when and where it is needed, you can organise the system around outcomes, not technology. It also means that we can bring together best-of-breed applications, working together as we require them to. So we can have a set of desktop editing tools pop up to cut pictures and sound alongside the script. If we want the video to be more finessed, we can hand the rough cut over to a craft editor – using EDIUS®, Apple, or a variety of other editor candidates – and the desktop editor goes about other business. In the well-crafted SOA, each tool is a lightweight piece of code, communicating with a central data backbone via a simple SOAP or HTTP protocol. These simple, XML-based interfaces make it easy to integrate multiple vendors’ components into the system. Small and easily developed XML filters, called “connectors” or “adaptors”, can be created by anyone with basic programming skills to bridge between different SOA environments. That central SOA backbone needs to be hosted, of course, and at Grass Valley™ we see that running on servers

communicating with the high-performance media storage and playout infrastructure, using our STRATUS™ architecture.

Together, it all adds up to simplicity, reliability and massive operational efficiency for the modern newsroom.
