## Discussion

This property is specific to MV-HEVC.

The property value is an array containing two view identifiers as numbers. The first value corresponds to the left eye and the second value corresponds to the right. The system incorporates the view identifiers into the 3D Reference Displays Info SEI message.

The property is NULL by default.
