Improved error screening techniques for use in processing digital audio or other types of information received in a digital communication system. Control information associated with a given packet of the received information is identified and compared with a decoding requirement of the packet, in order to control the generation of an error indicator for the packet. More particularly, the error indicator may be generated in response to an inconsistency between the control information and the decoding requirement. For example, the control information may include an indication of packet length that can be compared to a number of bits required to decode the corresponding packet, with any inconsistency between the packet length indication and the number of required bits leading to the generation of an error flag for the packet. The invention is particularly well- suited for use in the processing of encoded digital audio information received in a hybrid in- band on-channel (HIBOC) digital audio broadcasting (DAB) system, but is also applicable to other types of information and other types of communication systems.
