In the recent years in most of the Hungarian households the old, cathode-ray tube televisions have been changed to displays using new technologies, generally high definition visualization. Although, these televisions have a bigger screen size than the old ones, they only provide good of a quality, detailed picture, in case of real HD resolution content.

That’s why, with the spreading of the HD devices, increases the need of high definition television shows. It is a big challenge for most of the television companies, because the available studio devices are not serviceable for the production of high definition contents. To broadcast HD programmes for a channel’s total running time it usually needs a big investment to the whole technical infrastructure to be developed or changed. That’s why several Hungarian, national coverage television channels have not done any steps for high definition programs yet. The biggest television companies have already done developments, but the equipment was slightly improved, and the most of the programs are being showed in standard definition in the future.

In my thesis I study the technical requirement of the changeover for high definition format. Based on this theory I research how the Hungarian television companies’ old systems could be developed and what kind of innovation or optimization can be applied in the structure of the system and in the workflow of the production. According to the analysis I make a system plan from the concrete devices available in the market, which contains the whole informatical and video technical infrastructure needed for the HD production.
