Problems solved by technology
[0004] When the HDMI connector is in different working modes, the power energy control methods of the HDMI connector are also different. It is necessary to make the power energy control of the HDMI connector correspond to the working mode of the HDMI connector, otherwise it will affect the HDMI connector. For example, when the HDMI connector is connected to the HDMI Sink device, if the host plugs in the HDMI IN cable of the HDMI connector before it is turned on, the power energy of the HDMI connector will be reversed to the host, making the host There is an abnormality in reading data, such as an abnormality in reading EDID (Extended Display Identification Data, Extended Display Identification Data) data by the host through the SMBus bus (System Management Bus, system management bus), etc., resulting in abnormal data transmission from the HDMI connector to the HDMI Sink device;

An embodiment of the invention provides a power energy control method and a power energy control system for an HDMI connector. The power energy control method comprises the steps of when a control chip detects accessing of HDMI equipment into an HDMI interface of an HDMI connector, determining the type of the HDMI equipment; performing setting which corresponds with the type on the power energy channel of the HDMI connector; and after setting which corresponds with the type is performed on the power energy channel, making a HDMI transmission channel which is controlled by the HDMI connector and corresponds with the type in an open state so that the HDMI connector transmits data through the HDMI transmission channel. The power energy control method and the power energy control device can realize a fact that power energy control of the HDMI connector corresponds with the operation mode of the HDMI connector, thereby ensuring normal operation of the HDMI connector.
Description
technical field [0001] The present invention relates to the technical field of energy control, in particular to a power supply energy control method and system for an HDMI (High Definition Multimedia Interface, High Definition Multimedia Interface) connector. Background technique [0002] The HDMI interface is a special digital interface suitable for image transmission, which can transmit audio and video signals at the same time. The HDMI interface mainly includes HDMIIN interface (HDMI input interface) and HDMIOUT interface (HDMI output interface); with AIO (AllInOne, integrated ) technology development, the HDMIcombo (connector) that can combine the HDMIIN interface and the HDMI interface came into being. [0003] The HDMI connector is mainly connected between the host and the HDMI device, and transmits audio and video signals between the host and the HDMI device; the HDMI connector mainly has two working modes, one is connecting the HDMI connector to the HDMISource device...
