摘要:
Techniques for interpretation of DVD assembly language programs for television (TV) receivers operating in Java TV environments are provided. The techniques can be used to implement a Java-based command/control enabling system. The Java-based command/control enabling system can be implemented as a Java-based DVD assembly language interpreter which interacts with various modules including video, audio, graphics overlay, and remote control modules. As such, the Java-based command/control enabling systems can provide similar command/control functions as those provided by DVD systems.

Improved methods and apparatus suitable for accessing synchronized data in a broadcast system are disclosed. A synchronized data accessing system providing an interface that can be used by a data requester to access synchronized data is disclosed. The data requester can initiate a request to access synchronized data using the interface, and data can be made available and accessed by the data requester through the interface.
摘要:
A system and method for providing a controllable virtual environment includes a computer (11) with processor and a display coupled to the processor to display 2-D or 3-D virtual environment objects. Speech grammars are stored as attributes of the virtual environment objects. Voice commands are recognized by a speech recognizer (19) and microphone (20) coupled to the processor whereby the voice commands are used to manipulate the virtual environment objects on the display. The system is further made role-dependent whereby the display of virtual environment objects and grammar is dependent on the role of the user.

A method to provide automatic content-based video indexing from object motion is described. Moving objects in video from a surveillance camera 11 detected in the video sequence using motion segmentation methods by motion segmentor 21. Objects are tracked through segmented data in an object tracker 22. A symbolic representation of the video is generated in the form of an annotated graphics describing the objects and their movement. A motion analyzer 23 analyzes results of object tracking and annotates the graph motion with indices describing several events. The graph is then indexed using a rule based classification scheme to identify events of interest such as appearance/disappearance, deposit/removal, entrance/exit, and motion/rest of objects. Clips of the video identified by spatio-temporal, event, and object-based queries are recalled to view the desired video.
摘要:
Methods and apparatus for managing execution of an application according to an application lifecycle. The application lifecycle is managed by an application manager through a set of commands that enable the application manager to cause the application to enter one of a plurality of states. In addition, the application can communicate with the application manager to indicate that the application cannot change its state as the application manager has requested or to request that the application manager change the state of the application to a particular state.
摘要:
The invention relates to methods and apparatus for accessing data that is periodically transmitted by a broadcaster. In accordance with one aspect of the invention, a receiver capable of reception of data is disclosed. The data is transmitted by a broadcaster in a broadcasting system. The receiver reduces the delay conventionally encountered in accessing periodically transmitted data in a broadcasting system.

摘要:
Methods and apparatus for loading and unloading classes associated with an application are disclosed. A class loader adapted for loading classes associated with an application is constructed. The class loader is employed to load one or more classes associated with the application such that the class loader maintains a reference to the one or more classes. The class loader for the application is then de-referenced such that the class loader is unreachable.

摘要:
Object detection for scene change analysis is performed by a statistical test applied to data extracted from two images taken from the same scene from identical viewpoints. It is assumed that a single change region corresponding to an object that is present in one image but absence in the other is given. In the case of TV data, the test consists of measuring the coincidence of edge pixels in each image with the boundary of the change region. In the case of IR data, the tests consist of measuring the pixel intensity variance within the change region in each image.
