Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a receiving device.
Background
With the development of information technology, people pay general attention to how to more effectively transmit information between devices. Conventionally, people generally use data lines to transmit information between devices, for example, in a conference, an HDMI interface of a notebook computer is connected with a large screen used in the conference in a wired manner, so as to realize screen projection of information on the notebook computer, however, generally speaking, the space of a conference room is limited, when a plurality of devices such as notebook computers need to be connected with the large screen, wiring becomes very difficult, on one hand, the wiring cost is high, such as the cost of wires and the wiring cost, and on the other hand, complicated wiring is not beneficial to maintenance and repair, which results in the increase of the maintenance and repair cost. Moreover, most of large screens have limited HDMI interfaces and cannot be connected with a plurality of notebook computers at the same time, which causes inconvenience in use of a wired information transmission system; for example, in a studio, a plurality of cameras are needed to shoot, and the content shot by the cameras is transmitted to a broadcasting station through an HDMI data line in most cases, so that the length of the data line and the difficulty of pulling the data line are limited, the cameras in the studio basically adopt a fixed machine position and cannot flexibly capture the optimal shooting angle, and the shooting by the plurality of cameras, namely, the shooting by the plurality of cameras needs a plurality of data lines to transmit the content, so that mutual entanglement among the data lines is easily generated to influence the arrangement of the machine position, even the shooting needs to be interrupted, and the broadcasting effect is greatly influenced.
In view of the above, an information transmission system using a wireless transmission mode is available in the market, which employs a transmitting end and a receiving end wirelessly connected to the transmitting end, the transmitting end is connected to a user's device using a USB interface, for example, a user's laptop computer, and transmits information on the user's device to the receiving end in a wireless manner, and the receiving end processes the received information and transmits the processed information to a terminal device, for example, a large screen used in a conference, via an HDMI interface, so as to share information on the user's device to the large screen terminal of the conference, thereby achieving the effect of screen projection.
The existing wireless information transmission system generally adopts a USB (universal serial bus) to transmit information of a transmitting end and equipment, and is widely known that the traditional USB cannot directly transmit audio and video signals, so that the existing wireless information transmission system can transmit the audio and video signals to be transmitted to the transmitting end through the USB after the audio and video signals are coded by means of the equipment of a user. On one hand, however, the general CPU has limited encoding capability for audio and video signals, and when the audio and video signals are encoded, the situations of reducing picture definition, sound quality, and the like occur, and the phenomena of delay, easy occurrence of blocking and the like occur when a dynamic video is projected, and the user experience effect is not good; on the other hand, based on the consideration of information security protection and protection of trade secrets, the unknown software installation may cause information leakage stored on the device by the user, and even for the coding software built in the transmitting end, absolute security cannot be guaranteed, that is, there is a risk of information leakage in the existing wireless information transmission system technology.
In addition, in the prior art, the receiving end can only receive the information of the transmitting end matched with the receiving end, the transmitting end is connected with the user equipment by adopting a USB, and the screen can not be projected through the existing system when the user equipment does not have a special USB interface. For this reason, receiving end devices supporting connection establishment with devices such as a tablet computer and a mobile phone are currently on the market, however, due to the fact that the transmission protocols of android and ios of two main operating systems of the current tablet computer and the current smart phone are different, the existing technology cannot be compatible with the two protocols at the same time, so that connection establishment with the android device or the ios device is only possible, and the technology is not practical.
That is, the conventional information transmission system has limitations such as wiring and inconvenience in use due to the use of a wired transmission system. On one hand, the wireless transmission system has poor transmission quality, which is easy to cause information distortion and transmission blockage, and has poor experience effect; on the other hand, extra coding software needs to be installed on the equipment, so that the risk of information leakage exists, and the information safety cannot be ensured; moreover, the existing wireless transmission system cannot realize the compatibility with different operating system devices, cannot meet the use requirements of people, and has low practicability.
