Title:
MONITORED DATA PROCESSING METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO2017008234
Kind Code:
A1
Abstract:
The present invention is applied to the technical field of video monitoring. Provided are a monitored data processing method and system, and the monitored data is a video code stream encoded based on H264. The method comprises: acquiring a video code stream; adding reference frames in the video code stream into a reference frame queue in sequence and writing same into a reference frame storage block, and adding a non-reference frame sequence corresponding to each reference frame into a non-reference frame queue in sequence according to an order of the reference frames in the reference frame queue and writing same into a non-reference frame storage block; and releasing a non-reference frame sequence of which a retention period exceeds a pre-set time threshold value, and if all the non-reference frame sequences of which a retention period exceeds the pre-set time threshold value are completely released, releasing a reference frame of which a retention period exceeds the pre-set time threshold value. In the present invention, storing a reference frame and a non-reference frame in separate blocks can save storage space, and preferentially releasing a non-reference frame data block when the storage space is insufficient, enables a user to still view monitored video of which a retention period has passed by means of reserved reference frames.
