TVBEurope 31 The Workflow “The channel wanted to create a robust
graphics solution that could manage the LEDs individually and in such a way that simultaneously multiple programmes could be created,” states Kacmaz. “Orad provided a platform that could do this, while allowing scaling up to accommodate HD in due course.” He says that the specification of a
powerful system with minimum hardware components, with low maintenance and operational expenses were also good reasons for opting for this technology, Kacmaz goes on, “The result is a news
set that provides a 270º LED display around the studio bringing new life to the presentation. For every video wall based production where there is a requirement for map animations, satellite feeds, backgrounds such as tickers, finance news or weather, 24 TV uses Orad to push to LED. It all adds up to dynamic presentations.” PowerWall provides eight genlocked 3G or 16 HD SDI signals that can be tiled across the video wall according to the size and shape required. Its resolution can range from 3840x1080 in the 2x1 setup, 7680x2160 in the 4x2 setup and a massive

cued, graphics can be prepared and updated with the latest data. Once the action is played, the animation is executed with all the relevant graphics.” 3DPlay can add graphics in a nonlinear
mode by triggering the selected action. These actions are then arranged into groups, and placed in 3DPlay’s workspace according to the production’s needs. 3DPlay can be used by broadcasters with a single channel television or by multi-channel playout centres, making it an efficient and scalable solution. Before the move to the new studios, 24 TV had already invested in a large

15360x2160 in the 8x2 arrangement, all from a single HDVG4 unit. According to Kacmaz, this high
resolution means the system creates visuals without any pixelisation, jittering or synchronisation issues. The version of HDVG4 in use at 24 TV accepts an eight HD input configuration, and displays video clips in most industry-accepted formats. The clip does not need to be physically present on the video wall/HDGV system. It can trigger content stored on a server via a network if, for instance, the edited piece is stored in a different location.
Precise line up Orad 3Designer, which is used to create the graphics, allows the whole video wall to be treated as a single scene. This enables the creation of full screen graphics without tearing where the video wall tiles meet.
“Users exercise complete control over
which of the elements in a graphics sequence will be exported to the video wall,” emphasises Kacmaz. Another Orad product – 3DPlay
networked with the HDGV4 – is used to send the created sequences to the video wall. Kacmaz explains that 3DPlay is an action based graphics controller allowing users to create and combine graphics, content, and animation into one button and define its actions. “When the action is
amount of Cinegy equipment for ingest, editing, archiving and playout for both studios and MCR.
The Cinegy equipment is used in conjunction with a newsroom production system that was developed by the channel itself. One part of the Cinegy set up – Air Servers – can provide additional feeds into the video wall, if required. Cinegy Air consists of two elements; Cinegy Air Control provides a state-of-the-art interface for controlling one or more Cinegy Air playout channels connected via TCP/IP. Where necessary, this configuration is attached to the video wall.
Summing up the video wall installation,
Kacmaz says, “This was a new experience for the channel, but the choice has been well justified. It makes the studio look really big and impressive. The flexibility of the graphics software – where they can use more layers than any other software in the business and all from a single box – was crucial. With the multiple layer – more than 250 – function of Orad, the designers at 24 TV are able to create layouts specific for displays simultaneously in realtime without any other software to manage the process. It is a very easy and fast way of working in this type of LED workflow/display.”
