  • Publication number: 20100231795
    Abstract: A device and method of processing signals of a digital interface include the digital interface (e.g., HDMI) transmitting digital A/V signals through one cable such that compatibility between devices is improved and no load is applied to A/V operations. In order to distinguish a physical disconnection of an HDMI cable, prevent the occurrence of system load caused by a complicated control method, and solve software (S/W) operation errors caused by entanglement of wires, a signal processing device effectively decides transient statuses of HOT-PLUG and RSEN signals by detecting a signal level of a CEC line, and reduces system load caused by comparing the action of HOT-PLUG and RSEN transient statuses to the detected signal levels of one or more CEC lines. Therefore, the signal processing device increases stability of A/V operations (e.g., a media playback function) unique to a system, and removes complex and time consuming operations while being controlled, thereby increasing HDMI compatibility.
