摘要： A system and method that selects among multiple encodings of the same content to adapt to available bandwidth and meet delay constraints by minimizing the switching lag is disclosed. The system and method include one buffer serving multiple data streams and a switching device. The switching device switches between the multiple data streams and discards data from the buffer that does not belong to a new stream to eliminate switching lag after a switching decision has been made.

摘要： A method, system and computer program product is disclosed for supporting role-based access control in a collaborative environment, wherein pluralities of users work together in a collaborative process using a software system. The method comprises componentizing the software system into a multitude of software components, and limiting access to specific software components to certain users based on roles assigned to the users as defined by a run-time state of the collaborative process. The set of components that a user can access is dynamic, that set can change based on the “context” or the step where the user is in a collaborative workflow/process. Thus, in comparison with traditional access control mechanisms, an embodiment of the invention combines three different elements: a) the set of components that comprise the application is partitioned in such a way as to make componentized role-based access control feasible, b) a method for specifying inter-component dependencies to enable role-based groups, and c) enabling the modification of the access privileges based on contextual information from a collaborative process.
摘要翻译： 公开了用于在协作环境中支持基于角色的访问控制的方法，系统和计算机程序产品，其中多个用户使用软件系统在协作过程中一起工作。 该方法包括将软件系统组合成多个软件组件，并且基于由协作过程的运行时状态定义的分配给用户的角色来限制对某些用户的特定软件组件的访问。 用户可以访问的组件集合是动态的，该集合可以基于“上下文”或用户处于协作工作流/进程中的步骤而改变。 因此，与传统的访问控制机制相比，本发明的实施例组合了三个不同的元素：a）构成应用的组件集合被划分成使组件化的基于角色的访问控制可行，b） 用于指定组件间依赖性以启用基于角色的组，以及c）基于协作过程的上下文信息来启用对访问权限的修改。

摘要： A method of hierarchical digital video summarization and browsing includes inputting a digital video signal for a digital video sequence and generating a hierarchical summary based on keyframes of the video sequence. Additional steps may include computing histograms for the digital video sequence; detecting shot boundaries within the digital video sequence; determining the number of keyframes to be allocated within each shot; locating the actual position of each keyframe within each shot; identifying keyframe locations by the largest consecutive difference criteria; pruning keyframes for an shot without meaningful action; extracting keyframes efficiently in the case of compressed video; and browsing the shots using the hierarchical keyframe summary.
