摘要： A sequence of picture slices is encoded as reference slices and non-reference slices, wherein the reference slices include B slices, by forming, for each B slice, at least one data packet containing data values derived from brightness and color information pertaining to the slice. The data packet for each B slice includes a header element indicating whether the B slice is a reference slice. The header element of each reference B slice has a value that depends on depth of the reference B slice in a hierarchy of discardability.

摘要： A method and apparatus are provided for continuously slitting amorphous ribbon into a strip without adversely affecting the unique electrical, mechanical and magnetic properties of the material. The method includes the steps of heating a localized zone to approximately the glass transformation temperature and substantially simultaneously indenting the ribbon. The combined heating and indenting force produces a clean, high quality cut edge along the strip. Preferably, the positive engaging force causing indentation is effective to plow softened material to form a crystallized ridge adjacent the cut edge. The ridge is easily removed by a rotating brush. The indenter roller preferably includes a substantially V-shaped peripheral edge to concentrate the heat and force against the ribbon. A control unit is employed to provide the optimum heat, force and speed of relative movement between the indenter and the ribbon.

摘要： Progressive I-slice refreshed MPEG data streams are transcoded to I-frame based MPEG data streams to enable trick play modes on a television appliance, such as pause, scan forward, scan backward, jump, or still frame displays for use, e.g., in film indexing (chapters). A progressive I-slice refreshed MPEG data stream 10 having I-slices distributed over multiple P-frames is received by a television appliance 300. The P-frames are decoded at decoder 220 to recover the I-slices which make up a complete I-frame. The recovered I-slices are assembled (e.g., by processor 230) into a complete I-frame. The complete I-frame is encoded at an encoder 250. A selected P-frame in the MPEG data stream is replaced with the encoded I-frame (e.g., via multiplexer 255) to provide an encoded I-frame based data stream 200. The I-frame based data stream is stored (e.g., in memory 240) for trick play mode use.

摘要： A method, protocol and apparatus for transporting Advanced Video Coding (AVC) content, e.g., using MPEG-2 systems is disclosed. Specifically, the present method is related to the carriage of various flavors of AVC streams in a uniform fashion over MPEG-2 systems (e.g., both transport and program streams). AVC coding mandates only the VCL (video coding layer) elements and all other elements such as parameter sets, timing data and display parameters are optional in the in-band AVC stream. As all of these elements are required by MPEG-2 systems and for conformance verification of AVC streams, the present invention discloses MPEG-2 system specific tools and/or constraints to generate the optional elements that are not present in the in-band AVC stream.

摘要： Temporal and spatial scaling of video images including video object planes (VOPs) in an input digital video sequence is provided. Coding efficiency is improved by adaptively compressing scaled field mode video. Upsampled VOPs in the enhancement layer are reordered to provide a greater correlation with the input video sequence based on a linear criteria. The resulting residue is coded using a spatial transformation such as the DCT. A motion compensation scheme is used for coding enhancement layer VOPs by scaling motion vectors which have already been determined for the base layer VOPs. A reduced search area whose center is defined by the scaled motion vectors is provided. The motion compensation scheme is suitable for use with scaled frame mode or field mode video. Various processor configurations achieve particular scaleable coding results. Applications of scaleable coding include stereoscopic video, picture-in-picture, preview access channels, and ATM communications.
