Abstract

An embodiment of the invention provides HDMI service equipment and relates to the television technology field. By using the equipment, generation of a screen flicker phenomenon of the HDMI service equipment is reduced. The HDMI service equipment comprises a HDMI interface, a transmission branch, a first switch unit and a control processor. A first end of the transmission branch is connected to a voltage pin of the HDMI interface. A second end of the transmission branch is connected to a HPD pin of the HDMI interface. A first end of the first switch unit is connected to the transmission branch. A second end of the first switch unit is grounded. A control end of the first switch unit is connected to the control processor. The control processor is used to sent a control signal to the first switch unit so as to control conduction and disconnection of the first switch unit when a situation that HDMI external connection equipment accesses the HDMI service equipment is determined. The equipment is suitable for a HDMI data transmission scene.

Description

technical field [0001] The invention relates to the technical field of television, in particular to an HDMI service device. Background technique [0002] HDMI (Hi-Definition Multimedia Interface, high-definition multimedia interface) is a digital video / audio interface technology, a dedicated digital interface suitable for audio and video transmission, and has been widely used in display fields such as televisions. [0003] Currently, chips or devices with video processing functions are equipped with HDMI interfaces, which has prompted more IP manufacturers to develop IP modules with HDMI data processing functions. The HDMI protocol must be followed when transmitting HDMI data through the IP module. The IP modules developed by different manufacturers have different details. Both the HDMI external device and the HDMI service device are equipped with an IP module. The IP module of the HDMI external device is set to send HDMI data to the HDMI service device. The IP module of th...
