Techniques for simulation of multi top-level graphical-containers (e.g., frames) in an object-oriented computing environment are disclosed. A Multi Top-level Graphical-Container Simulator (MTGS) can be provided to simulate multi top-level graphical container support for applications that expect to use a plurality of top-level graphical containers (e.g., frames, windows). A MTGS may be implemented as a layer between a GUI-based application and an operating system and/or hardware/device with limited or virtually no graphical support capability. The Multi Top-level Graphical Simulator (MTGS) can effectively isolate the operating systems and/or hardware/device from the GUI-based application, and yet hide this simulation from the operating system and/or hardware/device. MTGS may be implemented in a platform independent programming language (e.g., Java&#x2122; programming language using a set of Java&#x2122; classes which have been provided in the Java&#x2122; Swing development toolkit.

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.

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.

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.

Methods and apparatus for accessing synchronized broadcast data

Through the association of an IP address with each data stream, a single system may be used by a network card or a tuner to select multicast IP data. Each data stream is identified by a unique IP address. More particularly, a locator adapted for identifying a data stream is associated with one of a plurality of data streams. The locator is then mapped to an IP address. When it is determined that the IP address corresponds to a data stream locator associated with a data stream, a tuner is instructed to read the data stream associated with the data stream locator. However, when it is determined that the IP address does not correspond to a data stream locator, a network card identified by the IP address is instructed to read data from the associated network. Since each data stream may be associated with a plurality of multicast IP addresses, a multicast group address is specified to identify the appropriate multicast IP data transmitted in the data stream. Packets addressed to the multicast group address may then be received by either a tuner or a network interface card.

Methods and apparatus for selecting multicast IP data transmitted in broadcast streams

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.

Methods and apparatus for implementing an application lifecycle design for applications

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.
