摘要： A service gateway provides a proxy between a client protocol and a plurality of standard communication protocols. The service gateway provides asymmetrical routing, data compression and encryption to optimize client processing power and communication link bandwidth. The service gateway enables content translation between clients and service providers. The service gateway keeps track of client available memory and sequence numbers in messages to generate error codes when applicable. A store and forward message capability is provided along with abstract session identifiers. The service gateway supports user datagram protocol.

摘要： A method for playing back a program which includes one or more interactive applications. A program which is stored, either in the form of a data stream or as a set of files is played back from a storage device. When playback is started, applications which are detected are launched. Applications are detected in the playback of pushed content when they become available in the playback stream. Applications are detected in the playback of pulled content by comparing the validity ranges of the applications to a current playback index. When special playback modes are used, signals which affect the lifecycle of an application are detected and corresponding signals are generated to maintain the proper state of the application. During these special playback modes, these various notification signals may be conveyed to applications which are configured to operate during these modes. Applications which are not configured to operate during these special playback modes may be terminated when the special modes are initiated and restarted when the special modes end.

摘要翻译：一种用于回放包括一个或多个交互应用程序的程序的方法。以数据流的形式或作为一组文件存储的程序从存储装置回放。播放开始时，启动检测到的应用程序。在播放推送内容的播放流中回放时，会检测应用程序。通过将应用程序的有效范围与当前播放索引进行比较，在拉出的内容的回放中检测应用程序。当使用特殊播放模式时，会检测到影响应用程序生命周期的信号，并生成对应的信号，以保持应用程序的正确状态。在这些特殊播放模式期间，这些各种通知信号可被传送到被配置为在这些模式期间操作的应用。当特殊模式结束时启动和重新启动特殊模式时，不能配置为在这些特殊重放模式下运行的应用程序可能会终止。
