In this environment, only half the inputs and outputs that would have been required for full resolution 3D in a 1.5Gb/s infrastructure are needed. In the area of production storage

Some editing systems are not capable of supporting 3D, so a talented editor is required to edit the two eyes as if working with a single video source.

picture for many vendors. The multiviewer, once somewhat overlooked, has become a significant consideration in the digital TV space. Multi-display systems continue to evolve with richer features and better interoperability with other components in the workflow. Technical operations staff will benefit from a multiviewer that can produce separate left and right feeds, while creative staff will need to see the 3D image. This means that the ideal multiviewer for this environment will be capable of displaying both HD and 3D feeds. Contribution is the final stage of the


mobile production environment. Video networking systems exist to manage and transport contributed signals into the broadcast facility. The ideal 3D- ready system can accommodate standards-compliant audio, video and data into the plant while supporting the left and right eye feeds together.

3D contribution feeds come in and are handled in much the same way as they were on the way out of the mobile content acquisition environment. Fiber management and video networking systems handle the two signals together as a related pair, while frame synchronizers and converters can recover phase errors that can adversely affect the signal. A routing switcher will pick up the signal once synchronization for the two eyes is confirmed. As in the acquisition and production
