Method and an apparatus for reproducing bitstream having non-sequential system clock data seamlessly therebetween

Abstract: A system stream contiguous reproduction apparatus to which are input one or more system streams interleaving at least moving picture data and audio data, and system stream connection information includes a system clock STC generator for producing the system clock that is used as the system stream reproduction reference clock. The system stream contiguous reproduction apparatus further includes one or more signal processing decoders that operate referenced to the system clock STC, decoder buffers for temporarily storing the system stream data transferred to the corresponding signal processing decoders, and STC selectors for selecting a system clock STC referenced by the signal processing decoders when decoding the first system stream, and another system clock STC referenced by the signal processing decoders when decoding a second system stream reproduced contiguously to the first system stream.

Navigating media content via groups within a playlist

Abstract: Grouping and navigating media files within a playlist on a computer-readable medium. Software according to the invention selects one or more media files according to a grouping criterion to define a group from the media files. The defined group references the selected media files. The invention software generates a group header associated with the group. The group header includes a value identifying the defined group and a reference to another group to enable navigation. The invention software stores the selected media files, the playlist, the defined groups, and the associated group headers on a computer-readable medium. The invention software also includes playback software for navigating and selecting media files via groups within a playlist. In one embodiment, the invention is operable as part of a compressed media format having a set of small files containing metadata, menus, and playlists in a compiled binary format designed for playback on feature-rich personal computer media players as well as low cost media players.

High-capacity lithium insertion materials of lithium nickel manganese oxides for advanced lithium-ion batteries: toward rechargeable capacity more than 300 mA h g−1

Abstract: Lithium nickel manganese oxides Li[NixLi(1/3−2x/3)Mn(2/3−x/3)]O2 (x = 1/2, 2/7, and 1/5) are prepared and characterized by XRD and FT-IR, and the samples are examined in non-aqueous lithium cells at room temperature and 55 °C. Among these materials LiNi1/2Mn1/2O2 (x = 1/2) shows the highest operating voltage and the smallest polarization with a rechargeable capacity of ca. 230 mA h g−1 and Li[Li1/5Ni1/5Mn3/5]O2 (x = 1/5) shows the lowest operating voltage and the largest polarization with a rechargeable capacity more than 300 mA h g−1. Extraordinarily large rechargeable capacity of Li[Li1/5Ni1/5Mn3/5]O2 together with an anomalously long voltage plateau at 4.5 V only observed at first charging process is examined by window-opening charge and discharge, continuous charge and discharge combined with differential chronopotentiometry at room temperature and at 55 °C, and possible mechanisms are discussed in terms of lithium insertion scheme.

Moving picture coding method and moving picture decoding method

Abstract: A moving picture coding apparatus for performing inter-picture predictive coding for pictures constituting a moving picture is provided with a coding unit for performing predictive error coding for image data; a decoding unit for performing predictive error decoding for an output from the coding unit; a reference picture memory for holding output data from the decoding unit; and a motion vector detection unit for detecting motion vectors on the basis of the decoded image data stored in the memory. When coding a B picture as a target picture, information indicating whether or not the target picture should be used as a reference picture when coding another picture is added as header information. Therefore, in a decoding apparatus for decoding a bit stream Bs outputted from the moving picture coding apparatus, management of a memory for holding the reference picture can be facilitated on the basis of the header information.

Document search and retrieval system with partial match searching of user-drawn annotations

Abstract: In summary there is disclosed a document browser for electronic filing systems, which supports pen-based markup and annotation. The user may electronically write notes (60-64) anywhere on a page (32, 38) and then later search for those notes using the approximate ink matching (AIM) technique. The technique segments (104) the user-drawn strokes, extracts (108) and vector quantizes (112) features contained in those strokes. An edit distance comparison technique (118) is used to query the database (120), rendering the system capable of performing approximate or partial matches to achieve fuzzy search capability.
