Abstract:
1. A client server system comprising: a server apparatus equipped with a reproduction section to reproduce accumulated video data in a predetermined reproduction mode including a normal reproduction mode, a fast-forward reproduction mode and a fast-rewind reproduction mode, and a transmission section to transmit the video data reproduced by the reproduction section; a client terminal apparatus connected with the server apparatus through a wireless network equipped with a reception section to receive the video data transmitted by the transmission section, a storage section to store the video data received by the reception section sequentially, and an output control section to output the video data stored in the storage section to a display unit; a selection section to select the reproduction mode of the reproduction section; a setting section to set a time lag; and a control section to shift a reproduction position of video data in the first reproduction mode by the time lag set by the setting section, when a second reproduction mode is selected by the selection section during a reproduction operation by the reproduction section in the first reproduction mode, wherein the setting section comprises a setting screen display control section to allow the display unit to display a setting screen, an input section to input the time lag into an input space displayed in the setting screen; and a measurement section to measure a time period from reproduction of the video data by the reproduction section to input of the video data into an external input unit through a communication section, the measurement section including: an external output unit installed in the client terminal apparatus, to output the video data output by the output control section to an outside; the external input unit installed in the server apparatus, to input video data output by the external output unit; and the communication section to connect the external output unit with the external input unit, wherein the setting section sets the time period measured by the measurement section as the time lag.
