Problems solved by technology

[0005] However, there are various types of mobile terminals today, such as smartphones and tablet computers. Different brands and models of mobile phones or tablet computers have different resolutions, imaging capabilities, and shooting rates. Therefore, when a smart phone When the display terminal plays a video containing implicit information, when the mobile terminal uses its own imaging device to shoot, if the imaging characteristics of the mobile terminal are not considered to match the smart display terminal, it will inevitably affect the information displayed by the mobile terminal on the smart display terminal. Imaging effect, which leads to distortion of information when extracting implicit information and even fails to extract implicit information

Embodiment approach

[0059] Step S210, setting the modulation parameters of the implicit information according to the received imaging capability parameters sent by the receiving end;

[0060] Step S220, generating a display signal according to the modulation parameter and the implicit information;

[0061] Specifically, in step S210, the imaging capability parameters received by the sending end may include: the highest camera frame rate F of the receiving end r and the maximum pixel at the receiving end.

[0062] In this embodiment, the modulation parameters of the implicit information are set, specifically, the display frame rate F of the display signal t , the transmission rate R of the implicit information, the modulated carrier frequency f of the implicit information c , and the shaping waveform parameters of the implicit information are set.

[0063] In one scenario, the settings of the modulation parameters should simultaneously meet the following conditions:

[0064] (1)F t >60;

Abstract

The invention discloses an implicit information transmission method, device and system. The implicit information transmission method comprises the steps of transmitting an imaging capacity parameter to a transmitting end to enable the transmitting end to set a modulation parameter based on the imaging capacity parameter and generate a display signal based on the modulation parameter and the implicit information; and obtaining the implicit information based on the display signal pushed by the transmitting end. Under the precondition of guaranteeing that human eyes are visually non-inductive forthe embedded implicit information, transmission of the implicit information can be finished via a way of being suitable for the imaging capacity of a receiving end.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular, relates to a method, device and system for implicit information transmission. Background technique [0002] With the development of information technology, information transmission methods such as barcodes and QR codes are common in our lives. For example, adding social friends by scanning QR codes, or querying commodity prices by barcodes, etc. Usually, there is such an application scenario that when the TV is playing a program, a QR code will be displayed on a part of the TV screen, and the user can scan the QR code with a mobile phone to obtain the video playback URL so that it is convenient to watch on the mobile phone The program, or the user scans the QR code with a mobile phone to obtain some advertising information, introduction information of TV programs, and the like. [0003] However, there are certain defects in this method of scanning codes. Each t...
