Embodiment 1

[0048] Reference figure 2 , Shows a step flow chart of a method for detecting that a wireless HD data projection channel is blocked according to the first embodiment of the present invention.

[0049] The embodiment of the present invention provides a method for detecting that a wireless HD data projection channel is blocked, such as figure 1 As shown, the following steps can be included:

[0050] Step S201: The mobile terminal and the high-definition data receiver establish a wireless high-definition data projection channel.

[0051] In this step, the mobile terminal may be a terminal with a video playback function and WiHD function, such as a mobile phone or a tablet computer. Before establishing a wireless HD data projection channel with a high-definition data receiver (dongle), the mobile terminal needs to enable the WiHD function. The mobile terminal can establish a WiHD connection with the high-definition data receiver by reading the connection information in the NFC (NearFie...

[0067] Reference image 3 , Shows a step flow chart of a method for detecting that a wireless HD data projection channel is blocked according to the second embodiment of the present invention.

[0068] The second embodiment of the present invention provides a method for detecting that a wireless HD data projection channel is blocked, such as image 3 As shown, the following steps can be included:

[0069] Step S301: The wireless high-definition data receiver establishes a wireless high-definition data projection channel with the mobile terminal.

[0070] In this step, the high-definition data receiver may receive connection information sent by the mobile terminal, and the connection information may include identification information and address information of the wireless high-definition receiver. And verify whether the connection information is correct, and if the connection information is correct, establish a wireless high-definition data projection channel with the mobile terminal...

Embodiment 3

[0075] Reference Figure 4 , Shows a structural block diagram of an apparatus for detecting that a wireless high-definition data projection channel is blocked according to the third embodiment of the present invention.

[0076] The third embodiment of the present invention provides a device for detecting that a wireless high-definition data projection channel is blocked, which can execute the method for detecting that a wireless high-definition data projection channel is blocked provided in the first embodiment of the present invention, such as Figure 4 As shown, the following modules can be included:

[0077] The channel establishment module 41, the verification message sending module 42, the response message receiving module 43, the event generation module 44, and the prompt display module 45.

[0078] In the embodiment of the present invention, the channel establishing module 41 is used to establish a wireless high-definition data projection channel with the high-definition data r...

Abstract

The embodiment of the invention provides a method and device for detection of a shielded wireless high-definition data projection channel. The method comprises: a wireless high-definition data projection channel is built between a mobile terminal and a wireless high-definition data receiver; the verification message is sent to the wireless high-definition data receiver through the wireless high-definition data projection channel; it is determined whether the response message is received or not; if the response message is received, the event of changing the state of the wireless high-definition data projection channel is generated; and the prompting of the shielded wireless high-definition data projection channel is displayed according to the event of changing the state of the wireless high-definition data projection channel. According to the embodiment of the invention, a mobile terminal sends verification message to a wireless high-definition data receiver and determines whether the response message is received or not, if the response message is not received, it is determined that the wireless high-definition data projection channel between the mobile terminal and the wireless high-definition data receiver is shielded, the prompting of the shielded wireless high-definition data projection channel is displayed, and a user is prompted to adjust the position of the mobile terminal to eliminate the shielding.

Description

Technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to a method and device for detecting that a wireless high-definition data projection channel is blocked. Background technique [0002] WiHD (Wireless hdmi, wireless high-definition) is a wireless high-definition video transmission protocol running at a high frequency of 60GHz. WiHD technology can stably and reliably transmit high-quality, high-definition and uncompressed video, and allows consumers to transmit and play between multiple electronic devices. Compared with Wi-Fi (WIreless-Fidelity, wireless fidelity), WiHD adds support for 1080P and 3D, and the transmission distance is longer. [0003] However, for wireless signals, usually at the same power, the higher the signal frequency, the stronger the signal directionality, the greater the energy loss when crossing obstacles, and the worse the diffraction ability. Therefore, affected by the transmission distance ...
