In November 2012, TVN24 was the first news channel in Poland to switch to HD
Associated with the editing
operation is the archiving of material. Obrzud reveals that a very simple procedure has replaced a previously complex practice. “We ingest 100 hours per day, but there is no call to archive that much material. We keep the archive material for 28 days on the SAN network, from where all edit stations have access to the content. The archivist selects from the ingested and edited video clips those to be proxied, tagged, logged and transferred to the real archive system. Again, the archive system is our design and build. We used a software company to write and maintain the database application, logging and search tools according to our detailed specification.” He goes on to report that
searching for material is accomplished through a simple web browser of TVN24’s own design. “It’s yet another example of creating our own system for ease of use and cost effectiveness.”
Think big Innovation has also been introduced into the main studio of the news channel. In May of this year, the biggest video wall in Europe was installed by Barco. “We looked at a number of options and tested three of them before selecting the Barco OverView wall composed of 16x4 of OL-510 cubes,” states
Jędrzejczyk. “It provided us with the best edge definition, colour saturation and uniformity of
those we tested, and we felt the viewers should have best image possible.” The video wall is driven by TVN24’s designed system — a combination of Christie Spyder controller fed by video sources and graphics from VizRT. In addition, there is a Sharp LCD video wall that provides an additional background in the same studio. In July 2012, TVN24
upgraded its vision mixing systems by installing two Snell Kahuna 360 multi-format SD/HD production switchers. “This is the only mixer that does not have any restrictions in handling multiple formats,” explains Kielmel. “This was particularly important in our migration from SD to HD.”

He says that until all material
received by the broadcaster is in HD there will always be a need to accommodate different formats. The switcher automatically detects the format of the input signal and uses its FormatFusion3 technology, which supports a mix of SD, HD, 1080p, and now 4K, to provide the required output.
Alongside the main 350sqm studio with its newsroom
backdrop, TVN operates another studio for the CNBC channel. There are also three virtual reality studios powered by VizRT Virtual Studio systems. These VR studios are used for the Weather Channel (with output from a Viz Weather system) and magazine programmes. “The VR studio means that
we can accommodate many more different looking programmes in one studio, without long breaks

Kielmel concludes, “I believe Jan Jędrzejczyk
for the traditional set change.” declares Kielmel. VizRT is also used for
graphics preparation. Viz Artist, a 3D design, animation and compositing software, is employed for producing templates, while Viz Engines are used for graphics playout in both studios and post production. In addition, a Viz World system delivers maps to all VizRT systems throughout the broadcast chain.
that TVN24 is unique as a broadcaster in Poland. When you custom build anything, it means it is easier to sort out any problems without having to wait for a supplier to respond. We have devoted a great deal of effort to creating a workflow which is just right for us.”
