Method for managing visual type compatibility in a conferencing network system having heterogeneous hardware

摘要

A conference enabled X windows networking system using a method for determining the best match available for a conference owner's visual type is disclosed. In the system, the enabler determines if the visual type detected in the X protocol stream is the conference owner's default visual type, in which case it is matched to the participant's default visual type. If that is not the case, the system determines if a visual type is available on the participant which is compatible to that being referred to in the X protocol. If so, the system determines which of the compatible visual types is the best match to that being used by the application. If there is an exact match of compatible visual type, the system matches the participant's visual type to that of the conference owner. If there are no compatible matches, the system will determine if an incompatible match exists between the participant's available incompatible visual types and the visual type being used in the X protocol. If there are no incompatible visual type available, the system signals an error condition and takes the appropriate action. When a match is made between a participant's visual type and that of the conference owner, the matched visual types are removed from the lists of available visual types.
