Abstract
According to one embodiment, there is provided an instruction method for providing an instruction from a supply device to a processing device via an HDMI cable, the method comprising detecting a signal from an operating switch in the supply device, generating a packet signal in which instruction information according to the detected signal is described, in an ASCII description area of source product description (SPD) of a packet signal for use in the HDMI standard, in the supply device, supplying the packet signal from the supply device to the processing device via the HDMI cable, and detecting the instruction information from the ASCII description area of SPD of the packet signal in the supply device, and performing a desired operation accordingly.
Claims10
A supply device comprising:
- an operating unit which detects a signal from an operating switch;
- a generating unit which generates an instruction packet signal including instruction information in response to the detected signal from the operating unit, and describes the instruction packet signal in an ASCII description area of source product description (SPD) of a packet signal for use in the high definition multimedia interface (HDMI) standard;
- and
- an interface unit comprising a plurality of pins including one pin which supplies the packet signal including the instruction packet signal to an external device via an HDMI cable.
A processing device comprising:
- an interface unit comprising a plurality of pins including one pin which receives a packet signal for use in the High definition multimedia interface (HDMI) standard from an external device via an HDMI cable;
- a detecting unit which detects an instruction packet signal including instruction information from an ASCII description area of source product description (SPD) of the packet signal;
- and
- a control unit which, upon detecting the instruction information from the ASCII description area of SPD of the packet signal detected by the detecting unit, controls a supply device so as to perform a desired operation accordingly.
