Abstract:
1. A moving image communication evaluation system comprising: (a) a moving image response time measurement unit installed in a client communication terminal for transmitting a moving image request to a moving image server communication terminal connected to the client communication terminal via a network and receiving and displaying a moving image transmitted from the moving image server communication terminal in response to the moving image request, said moving image response time measurement unit for measuring response time between the moving image request and moving image display state change, wherein the moving image response time measurement unit comprises: start point time measurement means for measuring time at which the client communication terminal accepts the moving image request as a start point time; end point time measurement means for measuring time at which a moving image display state is changed in accordance with the moving image request as an end point time; response time calculation means for calculating the time between the start point time and the end point time as the response time, moving image display anomaly detection means for detecting an anomaly of moving image display; and duration measurement means for measuring the time during which the moving image display continues normally; and (b) a moving image response time evaluation unit for receiving the response time transmitted from said moving image response time measurement unit through the network and evaluating the response time in the moving image communication between the moving image server communication terminal and the client communication terminal wherein the moving image response time evaluation unit receives the response time transmitted from the moving image response time measurement unit and evaluates a satisfaction degree of a user based on the response time, and wherein if an anomaly is detected by the moving image display anomaly detection means and the duration measured by the duration measurement means is less than a predetermined allowed time, the end point time measurement means determines the measured end point time invalid, if an anomaly is not detected by the moving image display anomaly detection means and the duration measured by the duration measurement means is equal to or greater than the predetermined allowed time, the end point time measurement means determines the measured end point time valid and measures the end point time, if an anomaly is detected by the moving mage display anomaly detection means and the duration measured by the duration measurement means is less than the predetermined allowed time, the start point time measurement means determines that the start point time measured just after it is invalid, and if an anomaly is not detected by the moving image display anomaly detection means and the duration measured by the duration measurement means is equal to or greater than the predetermined allowed time, the start point time measurement means determines that the start point time measured just after it is valid, and measures the start point time.
