Abstract
An information transmit system includes a first communication element having a guaranteed quality required to transmit real-time information, and a second communication element different from the first communication element. The system also includes a transmission element for transmitting stored real-time information using the first communication element and for transmitting real-time data using the second communication element, where the real-time data using the second communication element has corresponding time stamps later in time than the real-time data transmitted by the first communication element. For example, a time stamp of the real-time data may be used to transmit the data in either a normal direction (using the first communication element), or in a retrospective direction (using the second communication element). The system also includes a storage element for storing the real-time data transmitted by at least the second communication element, and a switching element for monitoring a time stamp corresponding to the real-time data transmitted from the first communication element and a time stamp corresponding to the real-time data transmitted from the second communication element. The switching unit switches the output of the real-time information transmitted from the first communication element, to the output of the real-time data transmitted from the second communication element that is stored in the storage element, when the time stamp for reproducing the real-time data stored in the storage element has been reached.
