Process Acceleration for HEVC Using Parallel Characteristics Calculation and Pixel Array Conversion

To solve the problem of labor shortage due to the decrease in the working population in the construction industry, remote control systems with networked cameras and cockpits are being developed. Currently, the challenges that teleoperation systems faced mainly originate from the transmission of images between sensors and intelligent/control systems. To reduce the delay time that occurs in the transmission of high-definition video, the time required for video compression must be reduced. Therefore, to achieve a video delay time of 150 ms without affecting the operator's operation in a teleoperation system, we proposed, implemented, and verified parallel characteristics operations and pixel array conversion as methods to speed up video compression, and confirmed the speedup of 14.2%.
