Introduction
Running a multi-channel TV broadcast installation brings new headaches when 3D is involved. Live monitoring of dozens of TV channels is difficult enough. Over the years several manufacturers have developed automated monitoring solutions covering a whole range of tasks of increasing complexity. With the advent of 3D, there is literally a new dimension of monitoring tasks, because we have to check not only the integrity of individual video signals but also the correct relationship between the left and right video signals in a stereo pair. In addition, manual monitoring of 3D is more difficult than 2D because the operator would need either to wear glasses or accept the limitations of autostereoscopic displays. For these reasons, there is a burgeoning interest and market in automatic monitoring of 3D television.

Conclusion
This paper describes several techniques for the automatic monitoring of stereoscopic 3D video signals: format detection, disparity monitoring, left-right swap detection and automatic detection of the use of 2D to 3D conversion. There is a great deal of scope to “get machines to watch 3D for us” so that humans can concentrate on delivering and watching 3D content. Snell Ltd. is active in developing and implementing the algorithms described here for monitoring and correction of 3D video across its product range.
