Abstract

Compositors are identified in a manner that defines the position of the compositor in the compositor tree. Each compositor has its own “unique compositor identifier”. Starting at the most downstream compositor, it transmits its unique compositor identifier to all upstream compositors directly coupled to it. The upstream compositors receive the unique compositor identifier from the most downstream compositor. Each of the upstream compositors appends its unique compositor identifier to the unique compositor identifier received from the most downstream compositor to produce a “compositor tree compositor identifier”. The compositor tree compositor identifier identifies both the compositor and its position in the compositor tree. This enables an application to detect the structure of the compositor tree so that the application can determine a desired tiling configuration that exploits the structure of the compositor tree.
