Description
Technical field
The invention belongs to wireless communication technology field, be specifically related to a kind ofly improve the method for mobile phone terminal with webcam video transmission stability.
Background technology
The appearance of video monitoring, for safety and protection system provide one very large, the very large safety that ensure that people's property and life, video monitoring have by analog video monitor nowadays towards digital monitoring constantly progressive and development, monitoring is the physical basis that every profession and trade key sector or important place carry out monitoring in real time, administrative department obtains valid data by it, image or acoustic information, the process of paroxysmal abnormality event is monitored timely and remembered, in order to provide efficient, commander and height in time, arrange police strength, settle a case.
The monitoring client of traditional video monitoring is all be arranged on the monitor supervision platform being positioned at monitoring proximal site, the monitoring of this class is easily by the restriction in geographical position, once policer operation personnel leave control and monitor console, something unexpected happened, be not easy Timeliness coverage, so need to wait for constantly before monitor supervision platform, the not only restriction of monitored personnel present position, and the real-time of monitoring cannot be ensured, and the appearance of 3G mobile, 3G mobile is made to be applied in rapidly all kinds of occasion in every way, along with the development of mobile intelligent, 3G mobile starts to be used in the monitoring of increasing video network, the function that 3G mobile is powerful, and it is portable, connect can carry out Internet phone-calling by network, and transmission of video, 3G mobile is by the cooperation with IP Camera, both can reach the object of video monitoring by transmission of video, 3G mobile is easy to carry simultaneously, be not subject to the restriction in geographical position, can receiving video signals at any time, reach the object of monitoring in real time.
But the communication of existing IP Camera and 3G mobile cannot carry out real time phone call, IP Camera is when transmission video, 3G mobile can only be simple carry out video reception, its real-time and picture transmission quality all cannot control, and the speed that existing webcam video sends has been greater than the inbound pacing of 3G mobile terminal, so just make video real-time in transmitting procedure very poor, the accumulation of frame of video easily causes the disorder of picture, add the problem of interference aspect simultaneously, result in the increasing of transmission delay, easily there is the problem that the transmission such as flower screen and picture delay are unstable, the clear and orderly of mobile phone terminal display cannot be met like this, also the real function of video monitoring cannot be met, if there is the problem that card screen or picture are detained, the function of real-time monitoring just can not get withdrawing deposit, be unfavorable for monitoring safety.
Summary of the invention
Technical problem to be solved by this invention is: for the defect of prior art, there is provided a kind of and improve the method for mobile phone terminal with webcam video transmission stability, by the pattern that private network communicates, IP Camera and 3G mobile are connected, and by testing the video reception speed of 3G mobile, and net control camera makes its video transmission speed send according to fixing velocity amplitude, thus make 3G mobile can steady receiver, video at the uniform velocity, ensure the stability of transmission of video, reduce the problem of transmission delay, improve the transmission quality of monitor video picture, effectively decrease the generation of flower screen and picture retention problems simultaneously, successful, be worthy to be popularized.
