Abstract: Although the new criminal litigation law has stipulated the system of simultaneous sound and video recording, some problems still exist. For example, the sound and video recording is optional, and the delivery of sound and video records is not clear. After analyzing the causes, this paper suggests that we should, by drawing upon the legislation and judicature experiences in other countries, clarify and solve the following issues concerning sound and video recording so as to ensure the benign operation of this system: its litigant status, its judicial scope, its testimony and the punishment for violating the stipulations.
