Description

technical field [0001] The invention relates to the processing of surveillance video in the field of criminal investigation, in particular to a video universal transcoding system and method. It belongs to the field of criminal investigation business. Background technique [0002] With the deepening of the construction of safe cities and the popularization of social monitoring, criminal investigation and case detection work is increasingly relying on video surveillance video resources. A large number of built video surveillance systems have been widely used in the criminal investigation of public security. Due to the different types of monitoring equipment in our country, the different video recording formats of the monitoring system, and the different playback operations of the manufacturers' players, a series of problems have been brought to criminal investigations and cases: 1) The manufacturers' video players are different, and criminal investigators not only need a large...

Problems solved by technology

Due to the different types of monitoring equipment in our country, the different video recording formats of the monitoring system, and the different playback operations of the manufacturers' players, a series of problems have been brought to criminal investigations and cases: 1) The manufacturers' video players are different, and criminal investigators not only need a large number of terminals The equipment plays all kinds of videos, and it is necessary to master the operation of various players. In the case of solving a case where every second counts, this will waste precious time and delay the time to solve the case; 2) due to poor management of the social monitoring system, if there is a manufacturer If the player is lost, the captured video cannot be played; 3) The video format of the monitoring equipment and monitoring system is not uniform, resulting in a sharp increase in the workload of the public security organs for the storage, collection, processing, utilization, and review of massive video images. A large amount of suspected target information can only be kept scattered and sporadically in the notes and brains of the investigators, making it impossible to concentrate and effectively discuss the case

[0003] Patent No. "CN200810167363.9", the patent titled "Agent Screen Recording System and Implementation Method and Agent Screen Recording Quality Inspection System and Implementation Method", proposed an agent screen recording system and implementation method; the call center agent operation process Record the screen and store it locally. The screen recording device and identification information are stored in the search server; the quality inspection seat searches for the identification information of the related equipment through the search server, obtains the screen recording information from the corresponding seat, and plays it in the quality inspection seat , to conduct service quality inspection; but the disadvantage is that it cannot process surveillance video, and can only record the full screen rather than the designated area, and cannot realize the real-time browsing that is required for criminal investigation business.
