An interface apparatus and method for transmission and reception of a control signal and a digital stream between an audio/video (A/V) system and a digital data recording and/or reproducing device are provided. The device for recording and/or reproducing digital data includes: a storage unit storing digital data encoded in a predetermined format; a decoder unit decoding digital data stored in the storage unit; an interface unit transmitting the decoded data to an external device; and a control unit controlling the storage unit, the decoder unit, and the interface unit.

Apparatus and method for interfacing between A/V system and portable device

An automatic test apparatus for embedded software and an automatic testing method thereof, the automatic testing apparatus for embedded software, includes an output detector which collects interface status information in accordance with data transmission/reception from at least one of first and second electronic devices respectively loaded with first and second embedded software and exchanging data therebetween, and extracts a keyword from the collected interface status information, a scenario composer which uses identification information about the first and second embedded software and the extracted keyword, and composes a scenario corresponding to a predetermined event status and a control command generator which generates a control command to reproduce the event status based on the composed scenario. Thus, it is possible to previously detect unpredictable and predictable problems that may occur in interaction between the plurality of embedded software, interface operation to transmit and receive data, etc., and reproduce them.
