In recent years, the rapid development of surveillance information in closed-circuit\ntelevision (CCTV) has become an indispensable element in security systems. Several CCTV systems\ndesigned for video compression and encryption need to improve for the best performance and\ndifferent security levels. Specially, the advent of 360 video makes the CCTV promising for surveillance\nwithout any blind areas. Compared to current systems, 360 CCTV requires the large bandwidth with\nlow latency to run smoothly. Therefore, to improve the system performance, it needs to be more robust\nto run smoothly. Video transmission and transcoding is an essential process in converting codecs,\nchanging bitrates or resizing the resolution for 360 videos. High-performance transcoding is one of\nthe key factors of real time CCTV stream. Additionally, the security of video streams from cameras\nto endpoints is also an important priority in CCTV research. In this paper, a real-time transcoding\nsystem designed with the ARIA block cipher encryption algorithm is presented. Experimental\nresults show that the proposed method achieved approximately 200% speedup compared to libx265\nFFmpeg in transcoding task, and it could handle multiple transcoding sessions simultaneously at\nhigh performance for both live 360 CCTV system and existing 2D/3D CCTV system.
