Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for repeatedly testing applications that request dynamic web content. In one aspect, systems for the repeated testing of a collection of applications that request dynamic web content include a collection of application testing clients each comprising one or more data processing devices, each client programmed to test applications that request dynamic web content by executing assigned applications and a server system. The server system includes one or more data storage devices storing information characterizing the collection of applications that request dynamic web content that are to be repeatedly tested, one or more data processing devices programmed to repeatedly assign the applications in the collection to respective of the application testing clients for testing, and one or more communications interfaces operable to exchange information with the application testing clients.

Abstract: A method and device for synchronization and rate control of media data comprising adaptively computing an offset time using the reference time of a server, a local time of a client, and an associated time for presentation of the data, stamping the offset time on the media data, receiving the offset time stamped media data into a first buffer, processing the offset time stamped media data, computing an altered offset time, including the altered offset time with the processed media data, storing the processed media data in a second buffer, and selectively supplying the processed media data to a presentation sink unit according to the altered offset time, the server reference time, and the associated time of the media data.

Abstract: A method and a device for performing the method, are presented. According to the method at a step a reference time is received. At a further step an offset time using the reference time and a local time is computed. At another step a media data is received. At a yet another step the offset time on the media data is stamped and at still another step the media data is received into a first buffer and made available for processing substantially immediately. At a subsequent step the media data may be supplied to a sink unit according to the stamped offset time, the local time and an associated time.
