Apparatus for recovering an access unit stream of consecutive access units, representing video and/or audio content, from a sequence of logical frames of a transmission signal, each logical frame comprising a useful data section, wherein the consecutive access units are consecutively inserted into the useful data section of the sequence of logical frames, wherein the logical frames comprise logical frames into which no begin of an access unit falls, a begin of one access unit falls, and a begin of two access units falls, respectively, the apparatus being configured to, for a predetermined logical frame, into which a begin of an access unit falls, extract an access unit table from the predetermined logical frame comprising, per begin of the access units falling into the predetermined logical frame, a pointer pointing to a respective begin position within the predetermined logical frame, and locate, and commence extraction of, the respective access unit the begin of which falls into the predetermined logical frame, by use of the respective pointer, the apparatus also being configured to consecutively extract the consecutive access units of the access unit stream from the useful data section of the logical frames of the sequence of logical frames, wherein the apparatus is configured to extract from each logical frame a logical frame header indicating the absence of, or the length of an access unit table in the respective logical frame, and locate an extension of the useful data section of the respective logical frame depending thereupon, wherein the apparatus is configured to perform the consecutive extraction of the consecutive access units from the logical frames using a useful data extraction direction within the logical frames, and to locate a varying positioned end of the access unit table by applying the length of the access unit table in a counter direction contrary to the useful data extraction direction from a constantly positioned end thereof, and wherein the logical frame header indicates a length of the access unit table of the respective logical frames and the apparatus is configured to, in extracting the access unit table from the predetermined logical frame, consecutively extract a number of access unit table entries with stepping, starting at the leading or rear end of the logical frame or at a position within the predetermined logical frame, having a predetermined constant offset therefrom, in units of a constant length from one access unit table entry to the next, in order to obtain, for each access unit table entry, a pointer pointing to a respective begin position of the respective access unit, wherein the apparatus is configured to extract additional redundancy information for the logical frame header from the predetermined logical frame, and use same in order to perform data corruption detection or error correction attempts on the logical frame header, and, if the logical frame header turns out to be corrupted, step, starting at the leading or rear end of the logical frame or at the position within the predetermined logical frame, having the predetermined constant offset therefrom, in units of the constant length from one possibly present access unit table entry to the next, in order to obtain, for each possibly present access unit table entry, a putative pointer pointing to a putative begin position of a respective access unit and additional redundancy data, perform an access unit table entry individual data corruption detection on the possibly present access unit table entries, and locate, and commence extraction of, merely at access units at putative begin positions to which the pointers of those possibly present access unit table entries point which turn out to be correct by the data corruption detection. obtain, for each possibly present access unit table entry, a putative pointer pointing to a putative begin position of a respective access unit and additional redundancy data, perform an access unit table entry individual data corruption detection on the possibly present access unit table entries, and locate, and commence extraction of, merely at access units at putative begin positions to which the pointers of those possibly present access unit table entries point which turn out to be correct by the data corruption detection.
