摘要： A nonlinear editing system for audio, video and/or other source materials comprises a system to define at least one time line representing the edit, the time line being represented in the editing system as an operator graph. The operator graph includes operators, representing sources and time-based effects, and time varying connections therebetween. For each period of the defined time line wherein the connections do not change, a expression tree comprising a simplified representation of the operators and the connections required to render that portion of the time line is extracted. Each expression tree can be examined to ensure that all of the required sources and/or connections are available to render that portion of the time line in real time and, if this is not the case, a determination can be made of which portions of the expression tree can be pre-rendered to an intermediate result, the intermediate result being substituted into expression tree to provide real time rendering.

摘要： A method, computer program product, and data structure for reducing the contention for a global lock that impairs system efficiency. An object is assigned or has thereon a positive reference count and a negative reference count. Upon creation, the positive reference count is incremented to indicate creation and the object is placed in a global data structure. When a process thread or other stream of executable instructions initially accesses the data object, the global lock is acquired and the positive reference count incremented to indicate the object is being used. When a process thread or other stream of executable instructions finishes processing the object, an object lock or other assigned lock is acquired (if not already held) and the negative reference count is incremented to indicate that the object is no longer in use by that particular process thread. Upon deletion, the negative reference count is incremented and will now be equivalent with the positive reference count if no process threads are still using the object. The object is destroyed when the positive reference count and the negative reference count are equivalent. The test for when the object should be destroyed occurs at the end of normal use processing as well as deletion processing since the object will not be destroyed until all process threads or other streams of executable instructions have finished their processing. Since the global lock need not be acquired a second time upon finishing processing, excessive global lock acquisition is reduced so that less lock contention occurs.
摘要翻译：一种减少全球锁争用系统效率的方法，计算机程序产品和数据结构。对象被分配或具有正参考计数和负引用计数。在创建时，增加阳性引用计数以指示创建，并将对象放置在全局数据结构中。当进程线程或其他可执行指令流最初访问数据对象时，获取全局锁，并且增加正参考计数以指示正在使用对象。当进程线程或其他可执行指令流完成处理对象时，获取对象锁定或其他分配的锁定（如果尚未保持），并且增加负参考计数以指示该对象不再被该特定的对象使用处理线程。删除后，如果没有进程线程仍在使用对象，则负参考计数将递增，并且现在将与正参考计数相等。当正引用计数和负引用计数相等时，对象被破坏。在正常使用处理结束时进行破坏的测试以及删除处理，因为在所有进程线程或其他可执行指令流完成处理之前，对象不会被销毁。由于在完成处理后不需要再次获取全局锁定，因此减少了过度的全局锁定获取，从而发生较少的锁定争用。

摘要： Methods and systems for adjusting an operating system configuration according to changes in hardware components of a client computer. The adjusted operating system can boot on the client computer regardless of changes in the hardware configuration of the client computer since it was last connected to a network server. Before the operating system boots, a preliminary connection is established between the client computer and the server. During the preliminary connection, the system identifies hardware components that are new and that must be supported by the operating system for bootup to occur. In particular, the server sends information relating to the previous client hardware configuration to the client computer. The client computer compares its current hardware configuration to the previous hardware configuration information, thereby identifying its new hardware components. Information identifying the new hardware components is sent to the server. The server locates operating system components or device drivers that support the new hardware components and stores them in a specified repository at the server. The operating system, which is now reconfigured to support the current client hardware components, is downloaded to the client computer and boots thereon.

摘要： Methods and systems for recognizing a client computer as a replacement for a previous client computer or as being new to a computer network. When a client computer is connected to a server in a computer network, the client computer sends its unique identifier to the server. The server compares the unique identifier against a list of known unique identifiers. If the server determines that the unique identifier is unknown, the client computer prompts the user to select one of a list of user options, which include, for example, a replacement computer option and a new computer option. If the user selects the replacement computer option, the user also identifies the previous computer that has been replaced. The server then replaces the previous computer's unique identifier with the replacement computer's unique identifier, and assigns the replacement computer to an appropriate server computer. If the user instead selects the new computer option, the server assigns the new computer to an appropriate server computer. The methods may further include identifying the hardware components of the new or replacement computer and modifying operating system components with little or no user assistance.

摘要： A remote boot process uses a secret to sign and/or seal the data necessary to remotely boot a client from a server on a network to ensure the integrity of the data. The secret is generated by the server and securely delivered to the client during the initial setup of the client. The secret contains a one-way encryption of the password for the client account on the server. Each side balances a signed message with a verify and a sealed message with an unseal. Subsequent transactions between the client and server are conducted using messages encrypted with a key generated by the server and securely delivered to the client in a message sealed using the secret. The secret can also be used in conjunction with an access data structure to prevent unauthorized users from accessing data stored on the server on behalf of the client or other users. In other aspects of the invention, the secret is replaced by a client private/public key pair.

摘要： A method and system for synchronizing modules associated with audiovisual devices, generally for use with a digital non-linear editor. A logical clock communicates information, including time and state (clock operating mode) information, to hardware and software modules through a synchronization port. The synchronization ports convert the time information into values recognizable by the module, and offset the time as needed to maintain synchronization. The state information may effect module commands for controlling audiovisual devices, such as rewind, playback and capture commands to tape players, timed such that various devices having different preparatory timing requirements are synchronized. State information, such as information indicating that a device is ready, may be returned by the modules. Video editing features such as scrubbing, looping and frame-stepping are supported by the mode information that is communicated between the clock and the synchronization ports.
