Brief description of the measurement of the impact of a terminal of the reception of services

摘要

The method involves transmitting a test flow (1.5) comprising a test service constituted of audio and video signals, and receiving the flow. The service is decoded and restituted by a terminal (1.6). Test service restitution incidents are detected. The sensibility of the terminal is established based on test flow transmission power corresponding to a given frequency of the incidents. Physical quantity e.g. sound amplitude, related to the restitution is measured by a sensor e.g. light intensity sensor, near the terminal. The incidents are detected by modifying the quantity.
