摘要： Apparatus for processing a data stream (110) comprises a data stream receiver (150) operative to receive a transport stream (TS), TS storage apparatus (170) operative to store at least a portion of the TS having a beginning and comprising a plurality of TS packets. The apparatus comprises candidate determining apparatus (190) operative to determine, from among the plurality of TS packets, at least one TS packet comprising a candidate access point, candidate offset storage apparatus (170) operative to store in an index store a byte offset of the candidate access point, and arrival time storage apparatus (170) operative to store in the index store a plurality of indications of byte offset, each byte offset being associated with an arrival time of a received TS packet. The TS comprises a partially scrambled TS having a scrambled data portion (130) and an unscrambled data portion (140), and the data stream receiver (150) also comprises analyzing apparatus (160). The analyzing apparatus is operative to distinguish between the scrambled data portion (130) and the unscrambled data portion (140) and to provide the unscrambled data portion (140) for analysis by the candidate determining apparatus (190). The candidate determining apparatus (190) is operative to determine said at least one TS packet comprising a candidate access point based on examination of at least part of the unscrambled data portion (140) provided by the analyzing apparatus (160).

摘要： Apparatus for processing a data stream (110) comprises a data stream receiver (150) operative to receive a transport stream (TS), TS storage apparatus (170) operative to store at least a portion of the TS having a beginning and comprising a plurality of TS packets. The apparatus comprises candidate determining apparatus (190) operative to determine, from among the plurality of TS packets, at least one TS packet comprising a candidate access point, candidate offset storage apparatus (170) operative to store in an index store a byte offset of the candidate access point, and arrival time storage apparatus (170) operative to store in the index store a plurality of indications of byte offset, each byte offset being associated with an arrival time of a received TS packet. The TS comprises a partially scrambled TS having a scrambled data portion (130) and an unscrambled data portion (140), and the data stream receiver (150) also comprises analyzing apparatus (160). The analyzing apparatus is operative to distinguish between the scrambled data portion (130) and the unscrambled data portion (140) and to provide the unscrambled data portion (140) for analysis by the candidate determining apparatus (190). The candidate determining apparatus (190) is operative to determine said at least one TS packet comprising a candidate access point based on examination of at least part of the unscrambled data portion (140) provided by the analyzing apparatus (160).
