Problems solved by technology

[0002] At present, the transmission of film data is either by satellite transmission or through ordinary network transmission. However, no matter how it is transmitted, it cannot be avoided that it can be used directly after being received by the receiving terminal, which will lead to the flood of film data and seriously affect the development of the film industry.

Embodiment approach

[0058] As an embodiment, the second data acquisition unit 420 is specifically used to obtain the first encrypted information corresponding to the keyframe based on the first encoding mode and the second encoded mode based on the second encoding mode. Second encrypted information corresponding to ordinary frames.

[0059] As another embodiment, the second data acquisition unit 420 is also used to obtain a first data packet carrying the keyframe; acquires the first encrypted information carried by the header of the first packet; Carrying a second data packet with the normal frame; acquires the second encrypted information carried by the second data package.

[0060] The determination unit 430 is configured to determine whether the encryption type of the first encrypted information matches the encryption type of the second encrypted information.

[0061] Wherein, the determination unit 430 is specifically used to obtain a first encryption type of the first encrypted information and a...

Abstract

A movie data transmission method and device provided by the embodiments of the present invention belong to the technical field of movie data processing. The movie data transmission method is applied to a server, and the method includes: acquiring key frames and normal frames of the movie data to be transmitted; acquiring first encrypted information corresponding to the key frame and second encrypted information corresponding to the normal frame information; determine whether the encryption type of the first encrypted information matches the encryption type of the second encrypted information; if so, decrypt the key frame and the normal frame to generate a target key frame and a target normal frame; based on The target key frame and the target normal frame generate target movie data.

Description

Technical field [0001] The present invention relates to the field of movie data processing, and in particular, a film data transmission method and a device are involved. Background technique [0002] The current transfer of movie data either uses satellite transmission, either by normal network transmission, but no matter how transmission, it is unable to avoid being received, it can be used directly, resulting in flooding of movie data, which seriously affects the development of the film industry. Therefore, how to solve the above problem is the technical problem that is currently in needovers. Inventive content [0003] A movie data transmission method and apparatus provided by the present invention is intended to improve the above problems. [0004] A movie data transmission method provided by the present invention is applied to a server, the method comprising: obtaining a key frame and a normal frame to be transferred to the movie data; acquire the first encrypted informatio...
