Based on this, the invention can acquire the first video of the live broadcast site by controlling the video acquisition device 102, and store the first video by using the block chain storage method, because the block chain technology has high security, the stored data has high reliability and is not falsifiable, when the first video is stored by using the block chain storage method, subjective artificial data change is avoided, and the security and reliability of the first video can be ensured to the greatest extent. Secondly, filter first video to get rid of the noise of first video, because the second video is the video after the noise of removal, so the definition of second video is higher, and transmit the second video to 5G module 104, can improve the visual effect of live video. The 5G module 104 is configured to convert the second video into a 5G digital signal stream, and since the digital signal has stronger anti-interference capability, longer transmission distance, and smaller distortion amplitude in the transmission process, the 5G digital signal stream is more favorable for sending the video to an external media server through the 5G module 104, so as to improve the transmission quality of the video.

The embodiments of the present invention are not limited to these examples.
In one possible implementation, the storage processing module 103 includes a block chain storage sub-module 1031 and a video processing sub-module 1032 which are electrically connected. The block chain storage sub-module 1031 is electrically connected to the video acquiring apparatus 102, and is configured to acquire a first video and store the first video in a block chain manner. The video processing sub-module 1032 is configured to perform filtering processing on the first video to obtain a second video.
Specifically, after the video obtaining device 102 obtains the first video of the live broadcast site, the blockchain storage submodule 1031 stores the first video in a blockchain manner, because the blockchain technology has high security, the stored data has high reliability and cannot be falsified, based on this, the first video is stored by using the blockchain storage method, subjective artificial data change is avoided, the security and reliability of the first video can be ensured to the greatest extent, the condition that the collected video pictures are lost is avoided, the continuity of the live broadcast of the video is ensured, and further, the user experience and the visual effect in the live broadcast process can be improved. The video processing sub-module 1032 filters the stored first video to remove noise of the first video, and obtains a processed second video. Since the second video is the video from which the noise is removed, the second video is higher in definition.
It is to be understood that the three cores of the blockchain are divided into data storage, consensus mechanism, and encryption algorithm. The data storage form is realized by means of the Mercker tree, namely, the video information collected by a certain time node is divided into a block head and a block body, and the block head is connected to the longest main chain, so that the collected data can be orderly connected, the disorder of the ordering of the video information is avoided, and the effective information of the video is damaged. The consensus mechanism can effectively guarantee the authenticity and reliability of block chain data information storage, and the consensus mechanism can be calculated by means of distributed nodes, so that video information can be mutually verified, and the safety consistency of the video data information is guaranteed. The encryption algorithm mainly meets the requirement of data information security in a block chain, and the encryption technology in the block chain mainly uses a Hash algorithm to extract video data characteristics and uses fixed-length character strings to carry out data information identification so as to realize encryption processing on video information. Based on the above, the embodiment of the invention stores the first video by using the blockchain technology, and based on the high security of the blockchain technology, the stored data has high reliability and is not falsifiable, so that subjective and artificial data change is avoided, and the security and reliability of the first video can be ensured to the greatest extent.

In some embodiments, the video capture unit 1042 is a video capture card for implementing a video conversion function to convert the second video into a digital signal stream for editing and transmission by a computer. In practice, in order to improve the definition of the video to the maximum extent, a broadcast-level video capture card may be used when the network environment allows, the resolution of the captured image is higher, and the video signal-to-noise ratio is high, but since the video file is too large, the corresponding video data amount is at least 200Mb per minute. In addition, under the condition that the network transmission rate needs to be guaranteed preferentially, a professional-grade video acquisition card or a civil-grade video acquisition card can be adopted. The embodiments of the present invention are not particularly limited.
It is understood that the CPE is a Customer premises equipment (Customer premises equipment) capable of communicating directly with the base station. The 5G CPE belongs to 5G terminal equipment, receives a 5G signal sent by an operator base station, and then converts the signal into a WiFi signal or a wired signal, so that more local equipment can be connected with a network to realize information interaction.
