Abstract: Aiming at the poor wireless channel ang high error rate at the scene of fire, a joint source channel coding based on the multi-hardware encoder was proposed. With the compound control method, the receiving end would send the video quality evaluation result to the sending end in real time from the closed-loop control. Aiming at the possible failure of feedback channel, 3 encodes were employed for the H.264 encoding of different compression ratio for the same thermal imager from the open-loop control. Meanwhile, the most appropriate code stream was selected to be loaded into the data transfer ratio according to the attitude parameters of thermal imager provided by the gyroscope. Experimental results showed that the PSNR (peak signal to noise ratio), real-time capabilitiness, and reliabilitiness were improved on the basis of the guarantee of certain bandwidth.

Key words: joint source channel coding, thermal imager, video coding, wireless communication, gyroscope
