wTVision Graphic Success For Studio CG’s Sports Pack
Studio CG is being pitched by wTVision as the ‘the perfect package for Euro 2012’
wTVision’s newest turnkey software, Studio CG, can easily integrate graphics templates giving operators the power to easily edit, manage and control on-air graphics during a live studio programme. Studio CG was recently used to produce a studio programme that covered the All Africa Games 2011 in Maputo, Mozambique. For this project, Studio CG Sports Pack was used to launch sports onair graphics, such as scorebugs and statistics reports, with information added manually or automatically through synchronisation with an official data provider. The Sports Pack is an appropriate choice to develop sports-related studio programmes. It adds dozens of features that enrich sports broadcasts and can be integrated with the official graphics look of a given competition (such as continental leagues or the upcoming Euro 2012). It works with the rights holders, or customised templates can be used for the non-rights holders, designed by wTVision or the client. The studio station displays the software operation using a simple interface and offers a complete library of editable SD/HD graphic templates specially designed for sports, news, financial and entertainment programmes. Studio CG can also be applied to the iPad, allowing the presenter to control the information on display. All Africa Games was broadcast by Televisão de Moçambique (TVM) and wTVision’s solution enabled coverage of all 24 sports at the

event. With 48 countries attending and 5,000 athletes present, the event is one of Africa’s major sports competitions. wTVision integrated the competition’s official graphics, timers and the official sources, providing information and on-air graphics updated in real-time. ■

Getting Maximum Resolution In 3DTV
By Franco Visintin
3D images are carried over the existing HD production and distribution infrastructure using frame packing systems that combine the left and right pictures into a single HD frame. In some respects these systems are similar to those used for 3D movies in the 1950s. One method was to put the left and right images side by side in a single frame. Another method was to allocate the left and right eye images stacked above and below. The same formats have been adopted in the so-called ‘frame compatible 3D TV’. In the sideby-side format, the left and right images are inserted one next to the other in a 1080i HD frame. This requires a horizontal squeeze of the picture which reduces the horizontal definition to one half. In the top and bottom format, the left and right images are stacked vertically in a 720p or 1080p HD frame. In this case a vertical squeeze is required, and the vertical definition is halved. In both formats the quality of the picture is significantly impaired. A third method, the 3D tile format, uses a new technology that goes beyond the film model and avoids these limitations. As shown, two 720p images (left and right) are packed into a single 1080p frame. One 720p image is inserted unchanged, that is without any downsizing. The second 720p image is split into three parts or ‘tiles’, with a remapping of the pixel locations but without any filtering or decimation. Which of these systems provides the highest overall resolution? The table shows the results based on a mathematical computation, the full details of which are available on the Sisvel Technology website. Both the horizontal and the v e r t i c a l resolutions are expressed in terms of ‘samples per picture height’. Also, that in both axes, a Kell factor of 0.9 has been adopted, while for the

interlaced system an interlace factor of 0.7 has been adopted. The 3D tile format provides the best video quality because no ‘squeezing’ is taking place. Rather, the left and right images, both in the 720p/50 format, are packed inside a 1920x1080 frame and transmitted in the 1080p/50 format. This remapping process eliminates image degradation problems. Dr Franco Visintin is an international consultant in the field of communication technologies. ■
