Abstract
The invention discloses an adaptive method for wireless network video stream transmission, which comprises the following steps that: formats of a TCP data packet and a UDP data packet are determined; a receiving end requests a transmitting end for video transmission; the transmitting end transmits a video data stream to the receiving end in the form of the UDP data packet; the transmitting end periodically transmits the transmitting condition of the UDP data packet in a current channel to the receiving end in the form of the TCP data packet; after receiving the TCP data packet, the receiving end unpacks and analyzes the data packet, operates the data of the transmitting end and record data of the locally received UDP data packet to obtain packet loss rate information and feeds the information back to the transmitting end; the transmitting end regulates the organized format of a current UDP video stream data packet, the packed size and the transmission rate of the UDP data packet in real time according to the packet loss rate information so as to adapt to the change of the wireless network; and the steps are repeated until the wireless network video stream transmission is finished. The adaptive method has the advantages of solving the problems of jump and jitter in video transmission, along with clear and continuous video transmission and low time delay.
Description
Technical field
The present invention relates to a kind of video stream transmission method, specifically, relate to a kind of wireless network video flowing adaptation transmitter method.
Background technology
In recent years, growing along with radio network technique, and the continuous release of various new video compression algorithm, wireless network video monitoring system has obtained significant progress.
The core of wireless network video monitoring system mainly is the transmission control of video flowing in wireless network, but this also is the part of the most difficult regulation and control.Because the characteristics such as change channel, narrow bandwidth and data low priority of wireless network itself make the quality problems of video flowing transmission be difficult to be guaranteed.
Though the video compression algorithm of releasing has adopted some instrument under the environment that mistake easily takes place in the recent period, makes the transmission of video flowing have certain robustness.But for guaranteeing the practicality of video flowing transmission, we need adopt UDP that video streaming data packet is transmitted, and insecure delivery that udp protocol itself just carries out packet, can't handle out of order, packet loss and mistake, this will inevitably cause video of transmitting problems such as jump, shake to occur, and we must consider that a kind of rational subpackage algorithm handles video streaming data packet at these problems.
Summary of the invention
The present invention is exactly in order to overcome above problem of running into, and the adaptive approach of a kind of video flowing in wireless network that proposes, the mechanism of control of video flow point bag in real time, thus make video reach the purpose of smooth transfer, avoid occurring the problem of jumping, shaking.
The present invention adopts following technological means to realize goal of the invention:
A kind of wireless network video flowing adaptation transmitter method is characterized in that, may further comprise the steps:

As the further qualification to the technical program, described step (5) may further comprise the steps:
(5.1) the UDP message bag situation that arrives of receiving terminal recorder;
(5.2) receiving terminal is judged the type of message of tcp data bag, if the transmission situation of UDP message bag is then calculated packet loss;
(5.3) be packaged into the tcp data bag, send to transmitting terminal.
As the further qualification to the technical program, described step (6) may further comprise the steps:
(6.1) receiving terminal is accepted the tcp data bag;
(6.2) receiving terminal is judged tcp data bag type of message, if UDP packet loss situation, the transfer rate of regulating organized formats, packing size and the UDP message bag of current UDP video streaming data packet.
Compared with prior art, advantage of the present invention and good effect are: the present invention utilizes receiving terminal to send video request, after transmitting terminal receives video transmission request, send video flowing with the UDP message packet form, simultaneously, transmitting terminal regularly sends the transmission situation of working as prepass UDP message bag with the tcp data packet form to receiving terminal, receiving terminal receives after the tcp data bag, the parsing of unpacking, the record data of transmitting terminal data and local reception UDP message bag are carried out computing, draw packet loss information, feed back to transmitting terminal, transmitting terminal is according to the organized formats of the current UDP video streaming data packet of the real-time adjusting of packet loss information, the transfer rate of packing size and UDP message bag is to adapt to the variation of wireless network.The present invention has avoided that jumping appears in video transmission, the problem of shake, and video transmission is clear to link up, time-delay is little.
