no. 1 example

[0026] see figure 1 , is a flow chart of a method for processing a video stream on a radio and television cloud platform provided by an embodiment of the present invention. The following will be figure 1 The specific process shown will be described in detail.

[0027] Step S101, dividing the video stream data to be processed into multiple data blocks.

[0028] Wherein, the video stream data to be processed is distributed and stored in cloud HDFS.

[0029] As an implementation manner, the video stream data to be processed is divided into multiple data blocks according to a preset size, and the number of the multiple data blocks is denoted as N. For example, the size of the video stream data D to be processed is size, and it is divided according to mKB, then the number of blocks N=| size / m |.

[0030] Optionally, let the divided data block be d 1 ,d 2 ,...,d n , and remember d i (d i ∈D) The position sequence number in the original file is marked as o i .

Abstract

The invention provides a video stream processing method, device and equipment for a broadcast and TV cloud platform, and a medium, and belongs to the technical field of video processing. The method comprises the steps: dividing to-be-processed video stream data into a plurality of data blocks; selecting a part of the plurality of data blocks as to-be-encrypted data blocks according to a preset rule; encrypting each to-be-encrypted data block; performing distributed cloud storage of the encrypted data block and the unencrypted data blocks in the plurality of data blocks, wherein the storage sequence of the encrypted data blocks and unencrypted data blocks is different from a position sequence in the to-be-processed video stream data, so that in the open broadcast and TV cloud platform, thecriminals can read all the video stream data blocks stored on the cloud server, but cannot know which data blocks belong to the same file and in what order the data blocks are arranged to form file, thereby reducing the risk that a new media news video of the broadcast and TV cloud platform will be tampered.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video stream processing method, device, equipment and medium of a radio and television cloud platform. Background technique [0002] Radio and TV new media news video has the characteristics of mass, official, public, open, and on-demand convenience. It has become an important basis for the public, enterprises and institutions to obtain government-related information. However, during the transmission of Internet-based new media video streams, it is vulnerable to attacks by hostile hackers at home and abroad to tamper with normal signals. Once it is broadcast, it will seriously damage the image of the party and the government. However, the existing ones either use the traditional information encryption mechanism, but the overall encryption of massive video stream data is too complicated, which will seriously affect the system performance of video stream playback...
