Design of Multi-channel Video Codec Acquisition Unit Based on H.265 Encoding
In recent years,telemetry digital video has been widely used in various scenes on naval ships.However,the tradi-tional video monitoring equipment has the problem of reducing the quality of real-time video images caused by the excessive occupa-tion of image resources.In order to meet the requirements of real-time bitstream transmission,bitstream display and easy manage-ment of multiple monitoring devices on the ship,this paper designs and implements a video codec system.The system includes vid-eo capture and compression,video transmission,video display and command configuration and other functional modules.The paper is connected to the video server through Gigabit Ethernet,sends configuration instructions according to the protocol,and uses FFm-peg for hardware decoding.It realizes the transmission,display and control of multiple video streams.The test results show that the designed video codec system is practical,reliable and has good performance,and meets the use requirements.
