    摘要： A method and apparatus is described to achieve a fast service change. The method includes: receiving a plurality of transport streams at a client device, each transport stream including a plurality of encrypted services; decrypting an encrypted service from the plurality of encrypted services thereby forming a decrypted service; playing out the decrypted service; storing a portion of at least one encrypted service from the plurality of encrypted services in a storage device; receiving a request for displaying a different encrypted service; identifying a stored portion of the different encrypted service; decrypting the stored portion of the different encrypted service thereby forming a decrypted stored portion; playing out the decrypted stored portion of the different encrypted service at a faster than real time speed; storing a subsequent portion of the different encrypted service in the storage device, the subsequent portion corresponding to a subsequent portion of the different encrypted service received during the decrypting of the stored portion and the playing out the decrypted stored portion of the different encrypted service; decrypting the subsequent stored portion of the different encrypted service thereby forming a decrypted subsequent portion; and playing out the decrypted subsequent portion of the different encrypted service for display upon completion of the playing out of the decrypted stored portion.

    摘要： A computer-implemented letter-based method of encoding a length-significant portion of natural language text to generate a letter-based fingerprint of the text portion, the method including detecting letter-based locations of occurrences of pre-determined single-letter and/or multi-letter pattern(s) within the length-significant portion, the detecting being carried out such that at least some occurrences are detected in a word-boundary independent manner that does not depend on locations of word-word boundaries, for a pattern occurrence letter-position signal which describes letter positions of the occurrences of the patterns within the text portion, computing frequency-dependent absolute or relative magnitudes of signal strength for a plurality of frequencies, the computed magnitudes representing letter-based frequencies of the pattern occurrences within the natural language text portion, and storing the computed signal strength magnitudes at the plurality of frequencies, the generated fingerprint comprising the stored signal strength magnitudes. Related apparatus and methods are also described.
