Embodiment Construction

[0042]In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0043] see figure 1 , is a step block diagram of a video data storage method that supports switching code streams in the present invention. The storage method is applied to a host computer of a monitoring system. The monitoring system includes a camera device for acquiring video data and a host computer connected to the camera device for communication. It is characterized in that the method comprises the steps of:

[0044] S1: receive video data, judge simultaneously whether newly received the recording task trigger instruction that is used to carry out storage task, if so, then perform step S2; Store the code stream and store it in the storage unit;

[0045] S2: Judging whether there is a storage task in execution, and judging whether th...

Abstract

The invention discloses a video data storage method and system capable of supporting code stream switching. The method comprises the steps that after a trigger video instruction is received, whether an execution storage task exists or not is judged, when it is judged that the execution storage task exists, whether a first storage code stream of a new storage task corresponding to a newly received video task trigger instruction is higher than a second storage code stream of the execution storage task or not is judged, if yes, the rest execution time is calculated according to the executed time and video duration time in the execution storage task, and then a new storage task is executed after the video data in the next second in the execution storage task are received; if not, the rest execution time is calculated according to the executed time and video duration time of the execution storage task, then the execution storage task is continuously executed in the rest execution time, and the new storage task is executed at the next second after the execution storage task is completed. Through the video data storage method and system, high code streams and low code streams are flexibly switched in the video data storage process to achieve seamless splicing video storage.

Description

technical field [0001] The invention relates to the field of video storage, in particular to a method and system for storing video data supporting switching code streams. Background technique [0002] In life, due to the needs of protection, safety, management, etc., it is often necessary to automatically and continuously record real-time video information. While automatically recording, video information storage time, image resolution, and frame rate are often adjusted according to special needs. , it is also necessary to use different image resolutions for storage according to different security levels, and the quality requirements for video storage and playback are getting higher and higher. In order to ensure the best image quality, it also ensures the smoothness of image code stream conversion , the existing video stream switching technology is not only slow in speed and unable to transition smoothly during the switching process, but also not perfect in video image qual...
