Inventor: GOMEZ ETIENNE
IPC: H04N7/173
Filed: 2001-06-14
Abstract: For providing video-an-demand (VOD) a set comprising a plurality of N video programs at staggered time intervals is repeatedly transmitting from a VOD server to a network for access by a view box of an user; responsive to a request for access to a selected program by the user, there is selection of that in-progress transmission of the selected program for which a lead-in portion is shortest and storage of the program i n a buffer associated with the view box as it is transmitted. A previously stared beginning portion of the selected program having a time length sufficient to compensate for that time interval is selected, In a memory associated with the view box, and outputting to the  view box for display. The in-progress transmission stored in the buffer is continuously spliced to a conclusion of the beginning portion. All different video programs in a same set are transmitted with mutual time shifts equal to a fraction of the staggered interval.

Title: Length determination of nucleic acid repeat sequences by discontinuous primer extension
Inventor: LOWE ADAM L
IPC: C12Q1/6827
Filed: 1999-12-01
Abstract: Disclosed is a method for determining the number of repeat units in a repeat  region of a target nucleic acid. The method comprises a discontinuous primer  extension reaction wherein a primer is extended in discrete increments corresponding to a single repeat unit. Following each increment of primer extension, a detection step is performed in which a modulation in a signal i s detected when the primer has been extended by an amount equal to the total length of a repeat region. By counting the number of increments of discrete primer extension required to cause a modulation in the signal, the number of  repeat units making up the repeat region is determined. In the method, a plurality of different-sequence primers are contacted with a polynucleotide sample under conditions effective for the primers to anneal to primer- complementary regions in one or more target polynucleotides, to form one or more target-primer hybrid(s), wherein either (1) each different-sequence primer contains (i) a target binding segment and (ii) a tag segment having a  nucleotide sequence that uniquely identifies the target binding segment, or (2) one or more polynucleotides in the sample are tagged polynucleotides tha t contain a tag segment having a nucleotide sequence that uniquely identifies the attached polynucleotide. The tagged moieties can conveniently be immobilized on an array of immobilized tag complements for analysis.
