Abstract: A thread debugging device which can provide reliable debugging is provided when at least one thread is debugged among a plurality of threads which are executed in association with each other. According to the thread debugging device, a target computer (20) executes at least some processing of at least one target thread to be debugged among the plurality of threads, and further executes non-target threads, which are threads other than the at least one target thread among the plurality of threads, during execution of the at least one target thread while restricting access by the non-target threads to at least some hardware resources of the computer (20).

Abstract: An information creating method comprising the steps of: recording moving picture/audio information obtained from a moving picture/audio input apparatus; recording pieces of still picture information displayed on a plurality of displays connected to a network; and, when pieces of said still picture information are recorded, creating a reproduction management list of said pieces of still picture information that correspond to said moving picture/audio information. It is possible to chronologically grasp from the reproduction management list when and in which file name the information has been displayed on each of the displays and, when contents represented in an HTML format etc. are reproduced, it is possible to easily select a display pattern in which pieces of information are to be reproduced on the same screen, thus displaying pieces of still picture information one and all on a split screen as inserted therein.

Abstract: A method of the present invention comprises the steps of: recording moving picture/audio information from a moving picture/audio input apparatus; recording pieces of still picture information displayed on a plurality of displays connected to a network; and, when pieces of said still picture information are recorded, creating a reproduction management list of said pieces of still picture information that correspond to said moving picture/audio information. It is possible to chronologically grasp from the reproduction management list when and in which file name the information has been displayed on each of the displays and, even in a case where contents represented in an HTML format etc. are reproduced, it is possible to easily select a display pattern in which pieces of information are to be reproduced on the same screen, thus displaying pieces of still picture information one and all on a split screen as inserted therein. It is possible to reproduce a condition close to an actually held conference.

Abstract: The present invention relates to an information processing system etc. well applicable to a network electronic conference system etc. It can prevent deadlock of the entire system and conduct good exclusive control without giving rise to a trouble which may occur when, for example, a time-out method is employed. An information providing server, when not in a locked state, gives access permission to one of a plurality of client apparatuses that has transmitted an access request to it and is put in the locked state and, based on information from the client apparatus, it is released from the locked state when an access termination operation of this client apparatus is completed or when the access termination operation cannot be performed normally.
