Interfacing system for stream source apparatus and display apparatus and interfacing method thereof

A stream source apparatus comprising:

• a central processing unit controlling a series of operations for transmitting video/audio signals to the display apparatus, the central processing unit controlling an operation of the stream source apparatus according to an optical signal, which is received from the display apparatus, by an operation of a remote controller and simultaneously generating a response signal according to the received optical signal;
• a transmission packet stream generating unit generating a transmission packet stream corresponding to analog or digital video/audio signals inputted externally;
• a transmission packet stream processing unit processing the transmission packet stream generated from the transmission packet stream generating unit;
• a memory storing the transmission packet stream processed by the transmission packet stream processing unit;
• a decoder & video/audio processing unit reading to decode the transmission packet stream stored in the memory and carrying out a video/audio processing on the decoded transmission packet stream to output;
• a format transforming unit formatting the transmission packet stream outputted from the decoder & video/audio processing unit into a form suitable for the optical signal or receiving to format the optical signal according to a user's operation of the remote controller to input to the central processing unit, the format transforming unit formatting to output a response signal corresponding to the optical signal inputted from the central processing unit;
• an optical fiber;
• and
• an optical signal transmitting/receiving unit transmitting the optical signal outputted from the format transforming unit to the display apparatus through the optical fiber and receiving the optical signal from the display apparatus through the optical fiber to output to the format transforming unit.

A display apparatus comprising:

• a central processing unit controlling a series of operations of processing an optical signal transmitted from the stream source apparatus and judging a remote control signal received by a remote control receiving unit, the central processing unit transmitting the remote control signal to the stream source apparatus through an optical signal if the remote control signal is a signal for controlling an operation of the stream source apparatus or controlling the display apparatus to carry out a corresponding operation according to the remote control signal if the remote control signal is for controlling a predetermined operation of the display apparatus;
• an optical signal transmitting/receiving unit transmitting the optical signal transmitted from the optical signal transmitting/receiving unit of the display apparatus and the remote control signal by the remote control signal receiving unit to the stream source apparatus through an optical signal and receiving a corresponding response signal;
• a format transforming unit formatting the optical signal received by the optical transmitting/receiving unit into a digital video/audio signal form to output and formatting to output the response signal of an optical signal form to the central processing unit;
• and
• a video/audio processor outputting the analog or digital video/audio signals outputted from the format transforming unit to a display screen or a speaker.

An interfacing method for stream source apparatus and display apparatus, comprising:

• a judging step of judging whether a remote control signal inputted to the display apparatus in accordance with a user's remote controller operation is a signal for controlling an operation of the stream source apparatus or the display apparatus;
• a performing step of having the display device carry out a corresponding operation according to the inputted remote control signal if the judging step judges that the remote control signal is the signal for controlling the operation of the display apparatus;
• a transmitting step of having the display apparatus transform the remote control signal into an optical signal format to transmit to the stream source apparatus through an optical signal;
• and
• a step of having the stream source apparatus receive the remote control signal transmitted through the optical signal to carry out a corresponding operation according to the formatted remote control signal.
