Abstract
An audiovisual terminal, an audiovisual authentication system, a method of authenticating audiovisual education, a remote education method, and a recording medium readable with the audiovisual terminal, all suitable for authenticating the actual viewing of education programs, especially to authenticate the actual viewing in remote education. Through the audiovisual terminal, a viewer of an audiovisual program enters a confirmation code which is specific to the audiovisual program and is transmitted to a principal who authenticates viewing of the program, and time information corresponding to the viewing confirmation code. The time information corresponding to the viewing confirmation code is typically a time point at which the code is entered. It may also be a time interval calculated, for example, from the entering time. The audiovisual terminal confirms whether the viewer is actually viewing a remote education program. The time information is stored or transmitted in correspondence with a viewing confirmation code.
