Receiving apparatus

Technical Field

The present utility model relates to the field of communications technologies, and in particular, to a receiving device.

Background

With the development of information technology, how to more effectively perform information transmission between devices has received widespread attention. Conventionally, people commonly adopt a data line 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 that information on the notebook computer is projected on the screen, however, in general, the conference room space is limited, when a plurality of notebook computers and other devices all need to be connected with the large screen, wiring is very difficult, on one hand, higher wiring cost, such as the cost of wires per se and wiring cost, and on the other hand, complicated wiring is not beneficial to maintenance and repair, so that the cost of maintenance and repair is increased. In addition, most of large-screen HDMI interfaces are limited, and connection with a plurality of notebook computers cannot be realized at the same time, so that the information transmission system adopting a wired mode is inconvenient to use; for example, in a studio, a plurality of cameras are required to be adopted for shooting, content shot by the cameras is transmitted to a broadcasting guide table through HDMI data lines, the difficulty of the length and the stay wire of the data lines is limited, the camera in the studio basically adopts a fixed camera position and cannot flexibly capture an optimal shooting angle, and the plurality of cameras are required to be adopted for shooting, namely, the plurality of data lines are required to be used for content transmission, so that the mutual winding between the data lines is easy to generate, the camera position arrangement is influenced, even the shooting is required to be interrupted, and the performance is greatly influenced.

For this, an information transmission system adopting a wireless transmission mode appears on the market, which adopts a transmitting end and a receiving end wirelessly connected with the transmitting end, the transmitting end is connected with a user's device by adopting a USB interface, for example, a notebook computer of the user transmits information on the user's device to the receiving end in a wireless mode, 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, etc., so as to realize the effect of sharing the information on the user's device to the large screen terminal of the conference, thereby achieving the effect of screen throwing. However, in comparison with the wired transmission method, the wireless information transmission system simplifies the connection of the wires, but additionally adds a transmitting end device and a receiving end device, particularly corresponding to the receiving end device, which are generally placed adjacent to the terminal device, so as to shorten the distance between the receiving end device and the terminal device and shorten the length of the data line between the receiving end device and the terminal device, but generally, the terminal device is independently placed or installed, which results in that the receiving end device which needs to be placed adjacent to the surrounding of the terminal device is often available. Especially in the use scenes such as meeting rooms, most of the screens are hung on the wall, so that a counter is not arranged nearby the screens, the receiving end equipment is not available, the HDMI interface of the receiving end equipment and the terminal equipment and the connecting line between the interfaces do not have bearing butt joint capability, and the hanging of the receiving end equipment from the terminal equipment by the connecting line is not feasible. Although in some use scenarios, a counter is specially provided for placing the terminal device, and the receiving end device can be placed on the corresponding counter together with the terminal device, the counter is easy to be messy, and does not meet the aesthetic requirements of being popular and simple at present.

Therefore, many users are not willing to adopt the wireless connection mode to transmit data, but rely on the network to transmit wireless data, specifically, when screen projection is needed, the CPU of the user equipment is mobilized by software to encode the audio and video signals to be transmitted and transmit the audio and video signals to the terminal equipment through the network, the terminal equipment decodes the audio and video signals to obtain the needed audio and video signals through the CPU of the terminal equipment, however, on one hand, the general CPU has limited encoding capability of the audio and video signals, the situation that the picture definition is reduced, the tone quality is lowered, and the like can occur when the audio and video signals are encoded, the time delay is easy to occur, the phenomenon of blocking, and the like can occur when the screen projection of the dynamic video is carried out, the user experience effect is poor, on the other hand, all computers are easy to be influenced by the wireless security risk, any software infected by computer viruses can be easily implanted into the computer, and the computer is also easy to be invaded by hackers, and the information leakage risk exists.
