Abstract

A processor (403) is provided for processing identifiers of video and/or audio material. The processor is for use with a video and/or audio material processing device. The device has a plurality of inputs (IN) for receiving respective pieces of material to be processed, the pieces having respective identifiers, and an output (OUT) at which is output processed material, which is a combination of the input material, and a state output at which data defining the state of the device is output.

The processor is arranged to: detect (405) the identifiers of the input material; determine (406) from the state data the combination of the input material forming the output material; generate (407) an identifier for the output material; and associate the identifier of the output material with the identifiers of the input material used to form the output material.

Identifiers preferably indicate whether the material emanates from a recorder or from a live source.
