Ultra 265 – More than a deep compression technology
Unlike conventional video compression technologies which try to reduce storage costs by sacrificing resolution and frame rate indiscriminately, U-Code 2.0 chooses to use "IRP" (Intelligent Region Perception) to detect motion in each frame. Hence, scenes containing interesting information could be preserved while the other relatively static areas such as lawns, white walls could be squeezed to save storage.
In order to reduce bandwidth, U-Code 2.0 applies dynamic GOP (Group Of Pictures) technique, which suggests the time interval between critical I frames of the GOP can be dynamically adjusted by analyzing the picture variety trend. In other words, as the surveillance picture tends to be static, the GOP is elongated, while it tends to be movement, the GOP becomes shorter. Meanwhile, it uses V.I (virtual I frame) to ensure that media has a keyframe that contains critical information so that the NVR can run the Frame Accurate Search and Quick Playback.
Furthermore, U-Code 2.0 also supports frame rate controlling for different video content, we call it the dynamic frame rate. It is used to automatically maintain high frame rate monitoring for many moving objects, but decrease the frame rate for few moving objects cases. No more details will be missed for complex surveillance pictures, and no more storage will be wasted for simple monitoring situation.
Additionally, U-code 2.0 is able to be applied on all streams, which means it can reduce bandwidth for multiple uses. By combining U-Code2.0 and H.265, Ultra 265 can squeeze up to 95% bandwidth and storage space.
