Embodiment Construction

[0056]Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals denote the same or similar structures in the drawings, and thus their repeated descriptions will be omitted.

[0057] In order to solve the above technical problems, the current security and performance issues need to find a balance through other technical means. The present invention successfully solves the conflict between performance issues and security issues by utilizing the characteristics of H.264 frame data and the characteristics of the decoding unit. Better commercial effects can be achieved, that is, the important part of the...

Abstract

The invention provides a video data encryption transmission method, system and device, and a storage medium. The method comprises the steps that: a sending end splits video data into a first data packet and a second data packet; the first data packet comprises a video parameter set data and an image parameter set data; the sending end encrypts the first data packet, so that an encrypted first datapacket is obtained; the sending end sends the encrypted first data packet and the unencrypted second data packet to a receiving end; the receiving end is configured to assemble with a video stripe data packet after decrypting the received first data packet; and thus, complete video data is obtained. According to the video data encryption transmission method, system and device, and the storage medium provided by the invention, key data and ordinary data are separately processed; only the key data is encrypted; the problem that the real-time performance in the video data encryption process is insufficient can be solved; and in addition, the security of the video data is sufficiently ensured.

Description

technical field [0001] The present invention relates to the technical field of video data transmission, in particular to a video data encryption transmission method, system, equipment and storage medium. Background technique [0002] H.264 / AVC is a highly compressed digital video codec proposed by the Joint Video Team (JVT, Joint Video Team) jointly composed of ITU-T Video Coding Experts Group (VCEG) and ISO / IEC Motion Picture Experts Group (MPEG). Standard, can provide continuous and smooth high-quality images (DVD quality), under the same image quality, the amount of data compressed by H.264 technology is only 1 / 8 of MPEG2 and 1 / 3 of MPEG4. [0003] H.264 provides a network abstraction layer (Network Abstraction Layer), so that H.264 files can be easily transmitted on different networks (such as the Internet, CDMA, GPRS, WCDMA, CDMA2000, etc.). H.264 is widely used in the field of video communication with the current leading technology. For the video data that widely exis...
