The present invention is directed to methods and compositions for acquiring nucleotide sequence information of target sequences using adaptors interspersed in target polynucleotides. The sequence information can be new, e.g. sequencing unknown nucleic acids, re-sequencing, or genotyping. The invention preferably includes methods for inserting a plurality of adaptors at spaced locations within a target polynucleotide or a fragment of a polynucleotide. Such adaptors may serve as platforms for interrogating adjacent sequences using various sequencing chemistries, such as those that identify nucleotides by primer extension, probe ligation, and the like. Encompassed in the invention are methods and compositions for the insertion of known adaptor sequences into target sequences, such that there is an interruption of contiguous target sequence with the adaptors. By sequencing both “upstream” and “downstream” of the adaptors, identification of entire target sequences may be accomplished.

The disclosure provides methods of generating paired reads in sequencing-by-synthesis process, particularly, in systems with relatively short read lengths (e.g., 15-35 bases), such as for example, in single molecule sequencing by synthesis. Several implementations of the methods are provided. Of particular advantage are the methods that permit re-sequencing of the template, which yields lower error rates. The invention further provides methods of using paired reads, for example, for positioning them over repeats or for assembly into large sequences, including whole genome assembly.

A system and method are described for greatly increasing the number of services that can be encrypted with existing conditional access equipment. The method is most useful when many digitally compressed programs are encrypted at the same time. Only the most critical components of each compressed video, audio, or data stream are selected and then sequenced into a single stream. Additional formatting causes this sequence of segments from multiple sources to appear as a single continuous stream to the conditional access system. Once this stream has been encrypted, it is demultiplexed and the components are restored and re-sequenced into their respective programs. Messages such as the Entitlement Control Messages that are inserted into the stream by the encryption system, are also adjusted and included with each of the reconstructed programs. The technique not only allows encryption systems to be designed using less encryption hardware, but also simplifies the management of encryption sessions, particularly in on-demand programming applications.

The present invention provides a method and apparatus for re-sequencing data packets received from multiple devices in a packet-based digital communication system. A set of data packets is received by a data packet sequencer. Each data packet includes an indicator of the originator of the data packet. The data packet sequencer stores the set of data packets, preferably in an input buffer. The data packet sequencer reorders the data packets by retrieving a first data packet and determining the originator of the first data packet. The data packet sequencer then transmits all data packets that were originated by a first originator of the first data packet prior to transmitting data packets that were not originated by the first originator.

A method and apparatus for creating a trick play video display from an MPEG-2 digital video transport stream are described. A trick play transport stream frame sequence template for each transport stream frame sequence and trick play video display mode supported by a video recorder is stored in the recorder. When the recorder receives an input transport stream frame sequence, the sequence is identified and template corresponding to that sequence and the selected trick play display mode is selected. The template is used to identify frames of the input transport stream to be appended to the trick play display transport stream frame sequence. When the trick play transport stream frame sequence is constructed the program clock reference, presentation time stamps and decoding time stamps associated with the frames are updated from information in the template.

The signaling scheme from the lower layer to the upper layer is an ABORT notification. This ABORT notification comes with associated parameters to indicate to the upper layer which PDU can be requested for retransmission from the upper layer.

A re-sequencing system offloads the cycle intensive task of re-sequencing TCP packets from host memory using a partial offload engine to re-sequence out-of-sequence data packets. However, as opposed to re-ordering the actual data packets, no actual data copy is needed. Instead, packet descriptors associated with each data packet are generated, and it is the packet descriptors that are re-sequenced. The data packets themselves are temporarily stored in packet buffers while the packet descriptors are sorted into sequence. The re-sequencing system preferably re-sequences a data stream of TCP data packets received from an ethernet network. The re-sequencing system is implemented within a computing device, preferably a personal computer or a server.
