Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0037] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe various operations (or steps) as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not ...

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...
