Embodiment 1

[0031] Such as figure 1 As shown, it is a schematic structural diagram of a system for transmitting audio and video data collected by a camera in Embodiment 1 of the present invention. The system in Embodiment 1 includes: a camera 11 and an information transmission device 12, and the camera 11 is used to collect audio and video data; The information transmission device 12 is used to determine the amount of redundant information that needs to be deleted in the audio and video data packets collected and processed by the camera 11 according to the quality of the wireless communication network, and delete all redundant information according to the determined amount of redundant information that needs to be deleted. After the corresponding amount of redundant information in the obtained audio and video data packets is obtained, the data packets are transmitted through the wireless communication network.

[0032] The data directly collected by the camera 11 is audio and video signal...

Embodiment 2

[0038] Embodiment 2 of the present invention proposes a method for transmitting audio and video data collected by a camera according to the system architecture shown in Embodiment 1, as shown in image 3 Shown is a schematic flow diagram of the method in Embodiment 2 of the present invention, and the method includes the following steps:

[0039] Step 101: Receive audio and video signals collected by the camera.

[0040] The subject of execution of this step may be the information transmission device involved in Embodiment 1. When the camera is used to move freely to shoot, and after the audio and video signal stream is collected, the audio and video signal stream is transmitted to the information transmission device.

[0041] It is assumed that what the camera captures in the second embodiment is an analog signal stream.

[0042] Step 102: According to the attribute parameters of the received audio and video signal stream, determine whether the received signal stream needs to...

Embodiment 3

[0073] Embodiment 3 of the present invention also provides an information transmission device for transmitting audio and video data collected by a camera, such as Figure 4 As shown, the device includes a central control module 31, a sampling adjustment module 32, and a communication module 33, wherein: the central control module 31 is used to determine that audio and video data packets that need to be deleted after acquisition and processing by the camera are based on the quality of the wireless communication network. The quantity of redundant information; Sampling adjustment module 32 is used for according to the determined quantity of redundant information that needs to be deleted, deletes the redundant information of corresponding quantity in the audio-video data packet that obtains described; Communication module 33 is used for deleting redundant information The data packets after the remaining information are transmitted through the wireless communication network.

Abstract

The invention discloses a method, a system and a device for transmission of audio-video data acquired by a video camera. Main content contains the following steps of: when performing wireless communication transmission of the audio-video data packets processed after being acquired by the video camera, firstly, detecting network status of the current wireless communication network, based on the condition of the network status, determining the amount of redundant information to be deleted in the audio-video data packets to be transmitted, and then, transmitting the audio-video data packets after deleting the corresponding redundant data according to the determined data. In this way, the size of the actually transmitted data packets is suitable for the network status, and correct transmission of the data packets is guaranteed.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, system and equipment for transmitting audio and video data collected by a camera. Background technique [0002] The radio and television system needs to transmit a large amount of audio and video data in real time when producing live programs, especially for the transmission of high-definition video data, and its transmission rate can reach 270Mbps, which puts forward higher requirements on the transmission capacity of the link; For live programs, the error tolerance rate of audio and video data transmission is low. Therefore, the error tolerance rate of audio and video data is low during the transmission process, so the network bandwidth and quality (including delay, jitter, and packet loss rate) during transmission etc.) parameters by higher requirements. [0003] Since the data transmission of the radio and television system has the above requirements, when performing data...
