ABSTRACT:
A digital interface apparatus operable to transmit and receive non-compressed digital data can allow a data interface between digital image apparatuses such as a digital VCR and a digital camcorder and a computer. A transmission timing controller in the digital interface apparatus for transmitting and receiving digital data via an IEEE 1394 serial bus, generates a clock select signal and timing signals. A transmission memory records data to be transmitted in synchronization with the clock designated by the clock select signal according to the timing signals generated by the transmission timing controller and outputs the recorded data in synchronization with a third clock. A controller generates the third clock, adds additional information to the data output from the transmission memory to then be transmitted via the IEEE 1394 serial bus, receives data transmitted via the IEEE 1394 serial bus, and restores a frame signal from the information added in the received data. A reception timing controller generates the clock select signal and timing signals. A reception memory records data output from the controller in synchronization with the third clock supplied from the controller according to timing signals generated by the reception timing controller, and outputs the recorded data in synchronization with the clock designated by the clock select signal generated by the reception timing controller.
