    Abstract: A method to create interactivity between a main device and a secondary device. The method comprises receiving a main stream comprising a signal indicating the availability of the ongoing interactive experience related to the audio/video content and extracting the interactive data from the main stream, obtaining a main interactive application related to the interactive data by the main device, obtaining a secondary interactive application related to the interactive data by the secondary device, loading the main interactive application into a software module of the main device, executing the main interactive application with all or part of the interactive data, collecting by the main interactive application of the main device, result of user's interactions made on the secondary device during execution of the secondary interactive application, processing the received user's interaction by the main interactive application to produce a result, displaying the result on the screen together with the audio/video content.

    Abstract: 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.

    Abstract translation: 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。

    Abstract: A system and method for remote maintenance of user units allows efficient diagnosis of failures in a reduced time. Each user unit transmits to a management server, via a network, state data related to hardware and software parameters associated to an operating mode of the user unit. The method includes: storing state data in a user unit memory, monitoring state data stored in the memory, and detecting at least one datum of a state indicating an operational failure of the user unit. When a failure is detected, state data corresponding to current states of the user unit at the moment of the failure and state data corresponding to states stored during a predetermined period before the failure are extracted and transmitted to the management server which determines a statistic correlation coefficient between the values of each state of a user unit and the values of states of other user units.
