摘要： Methods and systems for managing multiple inputs that are capable of competing or contending for a particular or primary output are described. In one embodiment, the multiple inputs are managed through the use of a software-implemented matrix switch object, and an associated data structure that is used to program the switch object and resolve contention issues between the inputs. The matrix switch object can process the multiple inputs to provide a primary output. One implementation of the switch object uses virtual input and output pins to receive and provide data streams. One specific embodiment is used in connection with multi-media editing software that enables users build or define their own editing multi-media editing projects that incorporate multiple different user-selected clips, in the form of digital data streams, into an integrated project. Each clip can be defined in terms of one or more digital data streams, e.g. video and audio streams. One implementation method defines a first data structure that represents an editing project and processes the data structure to provide a second data structure that contains data that can be used to program the matrix switch object so that multiple switch inputs are routed to multiple switch outputs and contentions between the inputs for a primary output are resolved.

摘要： Methods and systems of processing multi-media editing projects are described. In one embodiment, a request for one or more multi-media files is generated on a user computer that comprises part of a network where multi-media files are maintained in a network-accessible location. The file or files are intended for use in a multi-media editing project. The request is intercepted and software executing on the user computer ascertains whether one or more of the requested multi-media files are located on the user computer. If the file or files are located on the user computer, they are retrieved and used. If a file or files are not locally available, the file or files are retrieved from the network-accessible location. In one embodiment, a multi-media file locator object is configured to intercept network-bound requests for multi-media files and determine whether requested files are locally maintained on a user computer. A list associated with the file locator object can reference local file directories on the user computer where multi-media files are stored, or have been stored in the past. Whenever a user retrieves a multi-media file from the network and saves it locally, if the directory in which the file is stored is not referenced on the list, the file locator object can update the list to include the new directory. If the file locator object attempts to locally find a multi-media file but cannot, the user can be prompted to point to a directory where they have stored the file. The list is then updated to reflect this new directory, and the directory is checked on subsequent searches for multi-media files. Accordingly, when a request for a multi-media file is received, only those local directories that are or have been associated with multi-media files can be checked.

摘要翻译： 描述了处理多媒体编辑项目的方法和系统。 在一个实施例中，在包括网络的一部分的用户计算机上生成对一个或多个多媒体文件的请求，其中多媒体文件被维护在网络可访问的位置。 文件或文件旨在用于多媒体编辑项目。 该请求被截取并且在用户计算机上执行的软件确定所请求的多媒体文件中的一个或多个是否位于用户计算机上。 如果文件或文件位于用户计算机上，则会检索并使用它们。 如果文件或文件不在本地可用，则从网络可访问的位置检索文件。 在一个实施例中，多媒体文件定位符对象被配置为拦截针对多媒体文件的网络绑定请求，并且确定所请求的文件是否在用户计算机上本地维护。 与文件定位器对象相关联的列表可以引用存储多媒体文件的用户计算机上的本地文件目录，或者过去存储的文件。 每当用户从网络中检索多媒体文件并将其保存在本地时，如果列表中未引用该文件所存储的目录，则文件定位器对象可以更新列表以包括新目录。 如果文件定位器对象尝试在本地查找多媒体文件但不能，则可以提示用户指向存储该文件的目录。 然后更新列表以反映此新目录，并在后续搜索多媒体文件时检查目录。 因此，当接收到对多媒体文件的请求时，只能检查与多媒体文件相关联的那些本地目录。
