Video processing apparatus, method and system

A method for video processing, characterized in that the method for video processing comprising the steps of:

• splitting an input video into two sub-videos having a frame rate lower than that of the input video;
• generating metadata for synchronization of the two sub-videos which corresponds to frames of each sub-video, and adding the metadata into respective sub-videos;
• performing, by two sub-video processing pipelines, parallel processing on the two sub-videos split out;
• monitoring and controlling the two sub-video processing pipelines based on the metadata such that the processing on the sub-videos between the two sub-video processing pipelines is synchronized;
• and
• assembling the processed two sub-videos into an output video having the same frame rate as the input video based on the metadata.

A video processing system, characterized in that the video processing system comprising:

• a device for input video processing configured to:
• split an input video into two sub-videos having a frame rate lower than that of the input video, and
• generate metadata for synchronization of the two sub-videos which corresponds to frames of each sub-video, and add the metadata into respective sub-videos;
• two devices for sub-video processing, each configured to process one sub-video split out by the device for input video processing;
• a device for synchronization of sub-video processing configured to monitor and control the devices for sub-video processing based on the metadata such that the processing on the sub-videos between the two devices for sub-video processing is synchronized;
• and
• a device for sub-videos assembly configured to assemble the possessed two sub-videos into an output video having the same frame rate as the input video based on the metadata.
