<p>The present invention relates to a command system of an HD-CCTV control protocol and, more specifically, to a command system of an HD-CCTV control protocol which is operated by a protocol frame in a 10 byte structure for an HD-CCTV control. The command system of an HD-CCTV control protocol includes: a byte 1 composed of a header; a byte 2 composed of an ID; a byte 3 and a byte 4 composed of an address 1 and an address 2; a byte 4 and a byte 5 composed of a command 1 and a command 2; a byte 7 and a byte 8 composed of a data 1 and a data 2; and a byte 9 and a byte 10 composed of a CRC 1 and a CRC 2. The present invention is able to: expand a command and a data code to prepare a case of developing a new device or a case of adding a function; and stably and accurately control a command process and a data transmitting/receiving process by detecting a communication error from the processes by checking if data damage exists in a transmission process and checking if data is normally transmitted to a designated destination.</p> |
