Multi Media Net virtual studio brings solutions to many audio-visual products.

The flexibility, efficiency and costs saving of a virtual set (3D graphics) give directors complete creativity freedom. It enables the virtualisation of real-world sets and environments in real time, with a high degree of visual uniformity, providing state-of-the-art hyper realistic scenes, enhanced by 3D graphics.

It is a TV studio that enables a real-time combination of people, real objects and computer-generated setting in a seamless manner.  “Chromakey” technology is also used to create this integration. A key point of a virtual studio is that the real camera can move freely in 3D space. In fact, the computer-generated setting is rendered simultaneously with the correct position, perspective, zoom and angle. This is what differentiates a virtual production from a simple chromakey. To enhance this aspect, Multi Media Net has created a 3-camera system, one of which is positioned on a 4,5-meter-long holder with a 6-meter dolly. The mobility of this camera highlights the benefits of a virtual studio, enabling the maximum real-time integration between people and settings.

Augmented reality (AR) is an enhanced version of the real physical world that is achieved through the use of digital visual elements delivered via technology (webcam, camera). Multi Media Net developed, both for its virtual studio and mobile devices, applications of augmented realty.

The camera tracking systems used by Multi Media Net for its augmented reality services are two:

• Mechanical tracking
• Tag tracking
  

Mechanical tracking: This technology requires the installation of a camera on a mechanical structure (tripod, arm…) that has electronic components that detect all the system movements. It is used mainly for conventional TV studios. All the data detected by the mechanical encoders are “packaged” and sent to the graphics engine through a serial port by an electronic control unit.

Optical tracking system (Tag): With this technology you do not need any electromechanical devices (the camera can be handheld on the shoulder). The process of camera tracking, in this case, occurs through the camera angle observation of a real object called TAG (a white tile with a black frame in our case, which can also be branded) that embraces at least 1/10 of the entire shot. The Tag can be also “handled” in movement…for example, holding it by hand and telling the specs of the 3D model used in that moment. Both systems are developed exclusively by Multi Media Net.

In Multi Media Net telepresence allows a person located in a remote venue to appear in our virtual studio as they were really there. They can interact in real-time with people physically present in the studio during the shooting.

Multi Media Net virtual TV studio offers a camera data recording system. It can be used for 3D compositing in post-production on chromakey shots. Thanks to the FBX format it is possible to use this camera movement data on the most common 3D-modelling software.
