Abstract:
1. A testing apparatus for a multimedia player in an enclosed environment, the testing apparatus comprising: a storage device storing a video comprising a plurality of scenes; a controller controlling the multimedia player to display the video, transmitting a switching instruction to the multimedia player to switch scenes in the plurality of scenes, and storing a transmitting time of the switching instruction in the storage device; a recording device recording ambient light intensities in the enclosed environment at a predetermined time interval when the multimedia player displays the video, and orderly storing the ambient light intensities as a light intensity sequence in the storage device; a processor; and a testing system executed by the processor, the testing system executing a method comprising: comparing the ambient light intensity in the light intensity sequence with a previous ambient light intensity in the light intensity sequence to acquire a difference between two adjacent ambient light intensities; determining a switching time of when the scenes are switched according to the difference between two adjacent ambient light intensities in the light intensity sequence; and comparing the switching time with the transmitting time to evaluate a delay characteristic of the multimedia player.
