Research on Military Narrow Band Channel Video Transmission Based on NBVTH Algorithm
With the fast development of information technology,the audio and video transmission has been widely applied in military and civilian fields.Aiming at the such features as narrow communication transmission band,strong electromagnetic interference and low network stability and others in the military environment,the video transmission coding used in the military narrow band communication is in urgent need of being optimized.Firstly,the video coding framework and the latest technology used in military nar-row band channel transmission are introduced briefly.Then,the NBVTH(Narrow Band Video Transmis-sion based on HEVC)algorithm is proposed,which is analyzed and compared with the commonly used H.264/AVC encoding method from such key technical indexes as the compression ratio,the compressed image quality,coding time delay and so on.The experimental results show that the coding performance of NBVTH is significantly improved,which is more suitable for the video transmission in the military narrow-band channel.
