Video code stream processing method, device and equipment and storage medium

Abstract

The embodiment of the invention discloses a video code stream processing method and device, equipment and a storage medium. The method comprises the following steps: encrypting a scrambling key original text by adopting a key of a next node to obtain a scrambling key ciphertext; sending the scrambling key ciphertext and the scrambling code stream to the next node, so the next node determines the scrambling key original text, wherein the scrambling key original text is used for descrambling the scrambled code stream to obtain a target code stream. By the adoption of the scheme, the operation iseasy and convenient, and the transmission processing is carried out on the scrambled code stream; only the code stream sending end and the code stream receiving end are required to negotiate the secret key; the generated scrambling secret key is encrypted; the scrambling code stream and the scrambling secret key can be transmitted at the same time; in the whole process, the scrambling or descrambling of the scrambled code stream can be realized without using a key server and a management server to obtain a scrambling key, the normal transmission of the scrambled code stream can be realized, and since the scrambling key cannot be obtained from the server, any node can normally decode without generating a blurred screen.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of monitoring, and in particular, to a method, device, device, and storage medium for processing video code streams. Background technique [0002] In a video surveillance system, it is necessary to scramble the video code stream for transmission, and the commonly used code stream scrambling method relies on a scrambling server to realize scrambling and descrambling of the video code stream. For example, both the code stream sending end and the code stream receiving end obtain a scrambling key from the scrambling server to descramble the scrambled code stream. [0003] However, when obtaining the scrambling key, each node that transmits the code stream and receives the code stream needs to communicate with the scrambling server to obtain the scrambling key for descrambling, that is, it needs to rely on the scrambling server to scramble the code stream. Scrambling and descrambling in...

Problems solved by technology

[0003] However, when obtaining the scrambling key, each node that transmits the code stream and receives the code stream needs to communicate with the scrambling server to obtain the scrambling key for descrambling, that is, it needs to rely on the scrambling server to scramble the code stream. Scrambling and descrambling, increasing the interaction path, making the stream transmission complicated

Moreover, it takes a certain amount of time to obtain the scrambling key, and there will be decoding artifacts during this period of time.
