Abstract: PROBLEM TO BE SOLVED: To provide improved error detection technology used to process digital audio information received by a digital communication system or information of other types. SOLUTION: To control the generation of an error indicator for a packet, control information relating to a given packet of received information is specified and compared with the decoding condition of the packet. More specifically, the error indicator can be generated according to the inconsistency between the control information and decoding condition. For example, when arbitrary inconsistency between a packet length indication and the necessary number of bits results in the generation of an error flag for the packet, the control information possibly includes an indication of packet length which can be compared with the number of bits needed to decode the corresponding packet. This invention is used suitably, specially, for the processing of encoded digital audio information received by a hybrid in-band on-channel (HIBOC) digital audio broadcasting(DAB) system, but applicable to information of other types and communication systems of other types.

Abstract: 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 we ll- 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.
