In my thesis, I created a custom hardware - and an associated software environment as well – which the Budavari Schonherz Studio desperately needs.

In every television studio, there is a need for effective monitoring of the incoming and outgoing signals. For such thing, we have to use an additional display which can show which signal is visible on each monitor, and which is on air.

After I examined the needs and the specific workflows of the Budavari Schonherz Studio’s production processes, and created the specification of the system, I designed the hardware for the task. It is a point-matrix LED display, which can be operated in three colours. It is driven by a microcomputer, which has an industrial serial interface using a strandard protocol to display the data coming from the system controller software.

I developed the a software too, to control the displays. The studio already had a control software, and now it can control the Under Monitor Displays too. This software was already capable of controlling the video routing switchers, and I extended it to support the studio’s new BlackMagic HD vision mixer. Thus the system is capable of dynamically update the texts below the monitors from the status of the routing switchers, and it can display which source is on air too.

With this development, I belive I managed to create a universal hardware. Thanks to the industrial standtard control input, implementing a popular UMD protocol, not only the Budavari Schonherz Studio can benefit from it, but every other televison studio can use this kind of hardware.

During the process, I overcome a lot of further development opportunities. With them, this display (or even its software platform) can outstand many similar products created by professional companies.
