Embodiment approach

[0073] As an embodiment of the present invention, the method for detecting the available remaining storage capacity is as follows: the management node calculates the sum of the current remaining storage capacity and the storage capacity occupied by the second bit rate video data in the stored dual bit rate video data, Get the available remaining storage capacity. The available remaining storage capacity at this time is the sum of the current remaining storage capacity plus the storage capacity occupied by the second bit rate video data in the stored dual bit rate video data, because there is a first bit rate with the same content Video data, therefore, the second bit rate video data in the double bit rate video data can be deleted if necessary, so that the storage capacity occupied by it can be included in the category of available remaining storage capacity.

[0074] Suppose the current remaining storage capacity is P2, and the storage capacity occupied by the second bit rate...

Abstract

The invention discloses a video data storage method, device and system and a cloud storage-based video access method and device, and relates to the technical field of video data processing and storage. The video data storage method is applied to a cloud storage system, and the cloud storage system comprises a management node and a storage node. The method comprises the steps that the management node detects the available residual storage capacity; the management node compares the available residual storage capacity of the storage node with a first threshold, a second threshold and/or a third threshold; when it is judged that the available residual storage capacity is lower than the first threshold, the storage node receives and stores double code rate video data generated by front-end equipment; and according to the condition of the available residual storage capacity, the storage node deletes a stored part or first code rate video data and/or second code rate video data in all the double code rate video data. According to the method, video data with the higher definition can be saved when the storage space is enough, and longer-time video data can be saved when the storage space is not enough.

Description

technical field [0001] The invention relates to the technical field of video data processing and storage, in particular to a video data storage method and system, and a cloud storage-based video access method and node. Background technique [0002] With the development and wide application of video surveillance technology, the volume of video surveillance data is getting larger and larger, often requiring a huge storage space. Cloud storage is an emerging network storage technology extended and developed from the concept of cloud computing. A system in which application software works together to provide data storage and business access functions. Because cloud storage can easily expand storage space according to needs, it is especially suitable for large-capacity storage, so cloud storage technology has been widely used to store video data now. [0003] Currently, when video data is stored in the cloud, a coverage period (the minimum time required for each video to be sto...
