Embodiment 1

[0056] Such as figure 1 A schematic flow chart of a method for wirelessly sending high-definition audio and video, including the following steps:

[0057] Step S110, modulate the acquired audio and video data into multi-carrier signals, and the multi-carrier signals are located in the frequency band of 862-870 MHz or 902-928 MHz.

[0058] The wavelength of the radio signal in these two frequency bands is longer than that of 2.4GHz and 5GHz, so the multi-carrier signal in the 862-870MHz frequency band or the 902-928MHz frequency band has stronger penetration and diffraction capabilities, so the multi-carrier signal can be better distributed in Preset range, such as home, public places, etc., avoid blocking by walls, cabinets, etc.

[0059]As a preferred implementation, step S110 modulates the acquired audio and video data into a multi-carrier signal, and the multi-carrier signal is located in the 862-870MHz frequency band or 902-928MHz frequency band, specifically including th...

Embodiment 2

[0084] Such as figure 2 The shown high-definition audio and video wireless transmission method includes the following steps:

[0085] Step S210, the high-definition audio and video wireless transmission device transmits multi-carrier signals according to the high-definition audio and video wireless transmission method in Embodiment 1.

[0086] By modulating audio and video data into multi-carrier signals in the 862-870MHz frequency band or 902-928MHz frequency band for transmission, using the high spectrum utilization of multi-carrier channels to realize the transmission of high-definition audio and video data in the 862-870MHz frequency band or 902-928MHz frequency band , the multi-carrier signal penetration and diffraction capabilities of this frequency band are stronger, so the multi-carrier signal can be better distributed in the preset range, such as homes, public places, etc., to avoid blocking by walls, cabinets and other objects.

[0087] Step S220, the high-definiti...

Embodiment 3

[0104] Such as Figure 4 The shown high-definition audio and video wireless transmission device includes a memory 200, a processor 300, and a program stored in the memory 200. The program is configured to be executed by the processor 300. When the processor 300 executes the program, the above-mentioned high-definition audio is realized. The steps of the video wireless transmission method.

[0105] Correspondingly, the structural diagram of the high-definition audio and video wireless receiving device can also refer to Figure 4 As shown, it includes a memory 200, a processor 300, and a program stored in the memory 200. The program is configured to be executed by the processor 300. When the processor 300 executes the program, the steps of the above-mentioned high-definition audio and video wireless receiving method are realized.

[0106] Through high-definition audio and video wireless transmission and high-definition audio and video wireless receiving devices, high-definition...

Abstract

The invention discloses a wireless transmission and reception method and device, a transmission method and a system for high-definition audio and video, wherein the transmission method comprises the following steps: modulating the acquired audio and video data into multi-carrier signals located at 862-870 MHz frequency band or 902-928MHz band; and transmitting the multi-carrier signals through anantenna. By modulating the audio and video data into the multi-carrier signals at 862-870 MHz band or 902-928 MHz band for transmission, the high frequency spectrum utilization rate of the multi-carrier channels is used to realize transmission of the high-definition audio and video data at 862-870 MHz band or 902-928 MHz band, and the penetration capability and diffraction capability of the multi-carrier signals at the frequency band are higher, so that the multi-carrier signals can be better distributed in a preset range, such as home, public places, etc., to avoid shielding of walls, cabinets, etc.

Description

technical field [0001] The invention relates to audio and video transmission technology, in particular to a method and device for wireless transmission and reception of high-definition audio and video, and a transmission method and system. Background technique [0002] The existing wireless transmission of audio and video signals, such as the wireless extension scheme of HDMI data transmission, is generally realized through WIFI equipment, and WIFI modules are respectively installed at the sending end and the interface end. As users have higher and higher requirements on the transmission effect of audio and video data, such as stability and transmission rate, it is necessary to carry out wireless transmission of high-definition audio and video in a complex environment, and the wireless signal needs to have a strong ability to penetrate walls and surround However, the existing WIFI solutions have poor wall penetration and diffraction capabilities for wireless audio and video ...
