    • 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.
    • 使用定点算法以最小复杂度形成理想线性变换的近似,例如正向和反向离散余弦变换(DCT)。 该变换被分解成较小的一组变换(例如,DCT的LLM分解)。 然后,分解的乘法因子用定点表示近似。 然而,不是简单地应用缩放和舍入操作来产生最接近乘法因子本身的定点近似,而是选择具有效应的定点乘法因子(在各种分解阶段的级联操作之后)是最接近的 所得到的完整理想变换矩阵中条目的可行逼近。

    • A first frame of data is encoded and a first timestamp associated with the first frame of data is generated. The first timestamp includes complete timing information. The first frame of data and the associated first timestamp is transmitted to a destination. A second frame of data is encoded and a second timestamp associated with the second frame of data is generated. The second timestamp includes a portion of the complete timing information. The second frame of data and the associated second timestamp is then transmitted to the destination. Additional frames of data are encoded and additional timestamps associated with the additional frames of data are generated. The majority of the additional timestamps include a portion of the complete timing information.

    • Timecoding systems, methods and data structures are described which, in some embodiments, permit a true time to be ascertained from media samples whose timecodes contain an amount of drift which can arise from having non-integer frame rates. Inventive methods incorporate the use of an offset parameter that describes a time difference between a timecode and a true time associated with a media sample. The inventive approaches can be incorporated with and used compatibly in connection with current timecoding paradigms such as SMPTE timecode and the like. Further embodiments permit timecoding to take place at the field level of a frame. This can permit true-time calculations to be done to ascertain the true time associated with individual fields of a frame. In addition, other embodiments provide novel counting compensation methods that are directed to reducing the drift that can be associated with media samples that are sampled at non-integer frame rates.
    • 描述了时钟编码系统,方法和数据结构,其在一些实施例中允许从其时间码包含可能由具有非整数帧速率而产生的漂移量的媒体样本确定真实时间。 本发明的方法包括使用偏移参数来描述时间码与与媒体样本相关联的真实时间之间的时间差。 本发明的方法可以结合当前的时间代码范例(例如SMPTE时间码等)并兼容地使用。 另外的实施例允许在帧的场级进行时间编码。 这可以允许进行真实计算以确定与帧的各个字段相关联的真实时间。 此外,其他实施例提供了新颖的计数补偿方法,其旨在减少可以与以非整数帧速率采样的媒体样本相关联的漂移。

    • A system for implementing an intelligent window user interface for computers ("software suite") is disclosed. Each of a plurality of software suites of the present invention comprises a compound computer display object that provides a single integrated visual representation, via a "software suite window," for multiple application programs and/or files, which are represented in the suite window by icons. Each software suite has associated therewith a storage element in which is stored contextual information for defining the appearance and behavior of the software suite window and the icons displayed therein and for identifying the locations of files associated with the icons. This contextual information may also include, for example, an order in which related files in the suite are to be executed, as well as file history and manufacturing information for the items represented in the suite. In one aspect of the invention, the system enables a user, with minimal input, to initiate certain operations simultaneously upon all of the files represented in the software suite. In another aspect of the invention, the system facilitates the execution of a variety of operations that apply to the collective properties of the set of items as a whole, rather than to each of the items individually. In still another aspect of the invention, the system facilitates the deinstallation of files represented by a particular suite window or icon.
