Web based teleoperation architecture and H.264 video encoder

Abstract

Teleoperations is an important field in robotics. From surgical robots to space robots, it has found applications in different areas. This paper discusses the development of master side user interface and video encoder for video compression and transmission. It is a single robot, single user but multiple collaborator system. The master interface is developed using Adobe Flash and is cross operating system compatible. For video broadcasting purposes, a H.264/AVC encoder is developed using Intel IPP which uses latest multicore capabilities of new processors and can encode and transmit high definition videos over internet in real time. Encoder is designed to be used for video with slow moving objects in it. Use of Intel IPP provides better compression ratio, shorter encoding time and improved PSNR than existing video encoders. The results of our compression algorithm have been verified using PSNR analysis and human perception survey.Index Terms-Teleoperations, H.264/AVC, video compression, peak signal-to-noise ratio.
