Some ORs have large monitors displaying a variety of necessary information. Depending on the stage of the procedure, the information to display changes. To improve the quality of the real-time information shared inside the OR, it is relevant to automate the changes of layout and content of such a display, based on the metadata conveyed along with the video (e.g., displaying the endoscope image only when the endoscope is inside the patient body).

All the video streams have to be transferred with the relevant metadata (patient, study, equipment…) , as shown in Figure PPPP.4-1. Mechanisms to select and execute the layout of images on the large monitor are not defined. Only the method for conveying the multiple synchronized videos along with the metadata, used as parameters for controlling the layout, is specified.
