Benefits of technology

[0006] The present invention provides a method for recording and playback of remote presentation protocols such as the ICA protocol manufactured by Citrix Systems, Inc., of Ft. Lauderdale, Fla., the X protocol by the X.org Foundation, the Virtual Network Computing protocol of AT&T Corp., or the RDP protocol, manufactured by Microsoft Corporation of Redmond, Wash. The present invention reduces the time spent manually reviewing session recordings by reducing the time spent during playback rendering one or more sections of the recording where it can be algorithmically determined that the complexity of the recording or the importance of the recorded content is lower

Problems solved by technology

Many conventional methods lack the ability to reduce review time by eliminating sections showing interactions with certain windows or applications.
However, because the user is unaware of what is about to be rendered, they are prone to turning the speed up during sections of low interest and then missing detail

Embodiment Construction

[0039] Referring now to FIG. 1A, in brief overview, one embodiment of a client-server system in which the present invention may be used is depicted. A first computing device 100′ (generally 100) communicates with a second computing device 140′ (generally 140) over a communications network 180. The topology of the network 180 over which the first devices 100 communicate with the second devices 140 may be a bus, star, or ring topology. The network 180 can be a local area network (LAN), a metropolitan area network (MAN), or a wide area network (WAN) such as the Internet. Although only two first computing devices 100, 100′ and two second computing devices 140, 140′ are depicted in FIG. 1A, other embodiments include multiple such devices connected to the network 180.

[0040] The first and second devices 100, 140 can connect to the network 180 through a variety of connections including standard telephone lines, LAN or WAN links (e.g., T1, T3, 56 kb, X.25), broadband connections (ISDN, Fram...

Abstract

A background protocol engine receives a recorded session, said recorded session comprising a plurality of packets and representing display data. The background protocol engine determines a measure of complexity represented by at least some of the plurality of packets in the recorded session. The background protocol engine identifies an interval of time between the at least some of the plurality of packets in the recorded session. The background protocol engine modifies the interval of time, responsive to the measure of complexity represented by the at least some of the plurality of packets in the recorded session. The background protocol engine stores the modified interval of time. A foreground protocol engine renders the recorded stream responsive to the playback data structure.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a system and methods for time-warped playback and, in particular, for automatic time-warped playback in rendering a recorded computer session. BACKGROUND OF THE INVENTION [0002] Remote presentation protocols such as the ICA protocol manufactured by Citrix Systems, Inc., of Ft. Lauderdale, Fla., the X protocol by the X.org Foundation, the Virtual Network Computing protocol of AT&T Corp., or the RDP protocol, manufactured by Microsoft Corporation of Redmond, Wash., are inherently stateful. In order to view a particular point in a stream of recorded presentation protocol data, playback of the stream must begin from the very beginning of stream and played back sequentially until the particular point is encountered. [0003] Many conventional methods for session recording operate by taking screen snapshots periodically, and some of these increase the snapshot frequency in response to indications of potential interest gleaned fr...
