Abstract

The invention discloses a storage method, device and system for media data. Wherein, the method includes: obtaining storage association information of the media data to be stored, wherein the media data to be stored includes: current media data and historical media data, and the storage association information includes at least one of the following: time information, event information and storage area; according to the storage association information of the media data to be stored, the encoding information of the media data to be stored is obtained, wherein the encoding information includes at least: encoding mode and encoding parameters; according to the encoding information of the media data to be stored, the encoding information of the media data to be stored The media data is encoded to obtain encoded media data; the encoded media data is saved to the storage area of ​​the media data to be stored. The invention solves the technical problem in the prior art that the storage time of the media data is too short due to the limited space of the storage device.

Description

technical field [0001] The present invention relates to the technical field of video monitoring, in particular to a method, device and system for storing media data. Background technique [0002] With the development of video surveillance technology, the requirements for video storage are getting higher and higher. During the video recording process of high-definition cameras, a lot of space will be consumed, and it is increasingly difficult for storage devices to meet the requirements. Due to the limited space of the storage device, when the video is full, it will generally adopt a cyclic overwriting method to overwrite the previous data with new data, which will result in a short storage time of the video, and the expired data will be completely deleted and cannot be traced back. Blindly increasing storage space, in addition to increasing storage costs, is not applicable in many cases because storage devices often take up too much space. [0003] In order to solve the ab...
