Abstract

The invention discloses a computer device, a digital electronic system and a control method thereof. The control method for the digital electronic system comprises the following steps of: connecting the computer device to a digital audio and video device; executing an application program of the computer device, and transmitting a control signal to the digital audio and video device after audio and video contents are selected; when the digital audio and video device is in a standby state, starting the digital audio and video device, and performing switching to a computer device channel; and playing the audio and video contents of the computer device in the digital audio and video device. Therefore, the inconvenience of film watching realized by utilizing a high-definition multimedia interface is reduced.

Description

technical field [0001] The invention relates to a computer device, a digital electronic system and a control method thereof, in particular to the technical field of allowing an audio-visual device to wake up a dormant computer through a High Definition Multimedia Interface (HDMI) unit. Background technique [0002] At present, in recent years, High Definition Multimedia Interface (HDMI) has rapidly become the digital interface standard of global consumer electronic devices, and traces of HDMI devices can be seen everywhere in daily life. Usually, the source (Source) in the HDMI specification is, for example, a digital versatile disc player or a set-top box, and the sink (Sink), for example, is a projector or a TV or a speaker. [0003] HDMI includes a Transition Minimized Differential Signaling (TMDS) channel, a Display Data Channel (DDC), and a Consumer Electronics Control (CEC) channel. The TMDS channel is responsible for the transmission of all audio and video data. For...
