Host-side equipment, client-side equipment, computer and display equipment

Abstract

The invention provides host-side equipment, client-side equipment, a computer and display equipment. The host-side equipment comprises a data function module, a first receiving module, a first detecting module, a second receiving module, a second detecting module and a control module; the first receiving module is connected with the computer and is used for receiving the video signals transmittedby the computer; the first detecting module is used for detecting whether the first receiving module receives the video signals and outputting a first signaling when the first detecting module detectsthat first receiving module does not receive the video signals; the second receiving module is used for communicating with the client-side equipment and receiving a second signaling transmitted by the client-side equipment; the second detecting module is used for detecting whether the second receiving module receives the second signaling or whether the symbol information in the second signaling is connected with the display equipment and outputting a third signaling when the second detecting module detects that the second receiving module does not receive the second signaling or the symbol information in the second signaling is not connected with the display equipment; and the control module is used for controlling the data function module to be in a power-saving state according to the first signaling or the third signaling. The client-side equipment can be informed of being in the power-saving state when no video signal is inputted, thus the host-side equipment and the client-side equipment can consume least power.

Description

technical field [0001] The present invention relates to the computer field, in particular to a host device, a client device, a computer and a display device based on ultra-wideband (UWB) technology. Background technique [0002] At present, most of the wireless displays based on UWB technology are connected to the power supply separately to obtain sufficient power supply, such as between the computer and the display, between the computer and the projector, these displays or projectors have a separate power supply, but with the technology With the development of UWB technology and the maturity of UWB technology, when wireless display devices based on UWB technology are applied to mobile devices, such as between mobile PCs and mobile display devices, battery power must be provided for these mobile display devices. The power requirements of wireless display devices will be relatively high. [0003] When data transmission is performed between a computer based on UWB technology ...
