A decoding circuit and method for improving error correction capability using a stuffing byte, in which in the decoding method, an input data packet is decoded. The mounting system comprises a support structure which can be mounted to support columns via an optional tilt table. As a result, tape can be loaded and the maintenance work on each unit can be carried out easily. The compounds are useful therapeutically as sedatives or for the treatment of neurosychopharmacological disorders such as stroke, ischemia and epilepsy. The cradle is shaped and dimensioned for selectively receiving and securely holding the video system. The second die is shaped so as to partially overlap the first die, above the inner surface, with a portion suspended in cantilever fashion above the first die, by an overlapping distance.
