Abstract: The present invention discloses a method for encoding a flag of an image while encoding an I Frame, firstly setting a start code of an I Frame picture to be coded, for marking a start of the I Frame; setting a flag for indicating whether to code an identification field; judging the set flag, and if the flag indicates to encode the identification field of time and control code of a video tape recorder, encoding the identification field of time and control code of the video tape recorder, otherwise, not encoding the identification field of time and control code of the video tape recorder.

Abstract: Disclosed are a method and system for optimized, dynamic data-dependent program execution. The disclosed system comprises a statistics computer which computes statistics of the incoming data at the current time instant, where the said statistics include the probability distribution of the incoming data, the probability distribution over program modules induced by the incoming data, the probability distribution induced over program outputs by the incoming data, and the time-complexity of each program module for the incoming data, wherein the said statistics are computed on as a function of current and past data, and previously computed statistics; a plurality of alternative execution path orders designed prior to run-time by the use of an appropriate source code; a source code selector which selects one of the execution path orders as a function of the statistics computed by the statistics computer; a complexity measurement which measures the time-complexity of the currently selected execution path-order.

Abstract: Close approximations of ideal linear transforms, such as the forward and inverse discrete cosine transformation (DCT), are formed with minimum complexity using fixed-point arithmetic. The transformation is decomposed into a smaller set of transformations (e.g., the LLM decomposition of the DCT). The multiplication factors of the decomposition are then approximated by a fixed-point representation. However, instead of simply applying scaling and rounding operations to produce fixed-point approximations closest to the multiplication factors themselves, fixed-point multiplication factors are chosen that have the effect (after the cascaded operations of the various stages of decomposition) of being the closest feasible approximations of the entries in the resulting complete ideal transformation matrix.

Abstract: A method for modifying file contents of a flash file stored in a flash memory while balancing wear of the flash memory includes: finding first file nodes recording the file contents to be modified; searching for a plurality of void file nodes in the flash memory, selecting void nodes as second file nodes, and sequencing the second nodes based on node versions thereof; writing modified contents of the first nodes to one or more of the second nodes in ascending order of node versions of the second nodes; building node link information of the second nodes that have been written; marking the first nodes with a predetermined flag; vacating the first nodes that have been marked with the predetermined flag, and canceling node link information of the first nodes; and updating node versions of the second nodes that have been written and the first nodes that have been vacated.

Abstract: A fabric display includes a fabric arm having a main segment that extends forward and terminates in a reverse bend segment at a front end of the fabric arm. A bend arm extends rearward from the reverse bend segment and is adapted to support a leading “salvage” edge of a fabric sheet that is displayed on the fabric arm so that a relatively clean “roll” edge of the fabric is presented to viewers at a front end of the fabric arm adjacent the reverse bend segment. Opposing fabric arms may be attached to a pivotable support arm to allow viewers to easily observe two separate fabric sheets supported on the opposing fabric arms.
