Abstract

Automatic detection and processing of an empty multimedia data object is used to determine the data type of a multimedia data object. The system also detects whether the multimedia data object, or a component thereof, is empty based upon its data type. The system also appropriately processes a detected empty multimedia data object, or a component thereof. The appropriate processing may include no action, informing a user, program, or device of a detected empty multimedia data object, or a component thereof, inhibiting further processing of a detected empty multimedia data object, or a component thereof, or deleting a detected empty multimedia data object, or a component thereof.
