    • A method includes the step of intercepting, by a recorder, a presentation layer protocol data stream representing display data and comprising a plurality of packets, during transmission of the presentation layer protocol data stream from a first device to a second device. A protocol engine uses information associated with at least one copied packet to regenerate the display data represented by the at least one copied packet. In another aspect, a foreground protocol engine receives a request for rendering the contents of a packet in a presentation layer protocol data stream comprising a first plurality of packets already received and a second plurality of packets yet to be received. The foreground protocol engine displays, during transmission of the presentation layer protocol data stream from a first device to a second device, the requested packet responsive to an identified state-snapshot having an associated timestamp previous to that of the requested packet.
    • 一种方法包括以下步骤:由记录器在表示层协议数据流从第一设备传输到第一设备期间拦截表示显示数据并包括多个分组的表示层协议数据流, 第二个设备。 协议引擎使用与至少一个复制的分组相关联的信息来再生由至少一个复制的分组表示的显示数据。 在另一方面,前台协议引擎接收用于呈现包括已经接收到的第一多个分组和还有待接收的第二多个分组的表示层协议数据流中的分组的内容的请求。 前景协议引擎在呈现层协议数据流从第一设备到第二设备的传输期间显示所请求的分组,以响应具有在所请求的分组的时间戳之前的相关时间戳的所识别的状态快照。

    • 一种方法包括在表示层协议数据流从第一设备传输到第二设备期间由记录器拦截表示显示数据并包括多个分组的表示层协议数据流的步骤。 协议引擎使用与至少一个复制分组相关联的信息来重新生成由至少一个复制分组表示的显示数据。 在另一方面,前台协议引擎在包括已经接收的第一多个分组和尚待接收的第二多个分组的表示层协议数据流中接收呈现分组的内容的请求。 在将表示层协议数据流从第一设备传输到第二设备期间,前台协议引擎显示响应于所识别的状态快照的所请求的分组,该状态快照具有先于所请求的分组的时间戳。
