Description
Technical field
The invention belongs to aerial video transmission technique fields, and in particular to the Video transmission system based on ARINC818 agreement
Vibration control method, device.
Background technique
ARINC818 also known as aviation electronics digital video bus (Avionics Digital Video Bus), in 2007
January in year is by the formal externally publication of the aviation electronics committee (AEEC), it is therefore an objective to meet key figure transmission of video in avionics system
Demand.
ARINC818 agreement is a kind of Aviation electronics released based on optical-fibre channel-audio frequency and video agreement (FC-AV)
The dedicated video transmission protocol of system simplifies FC-AV agreement in content, for solving synthetic aviation electronic system
The systems image such as multifunction display, Helmet Mounted Display after system display pattern changes transmits and realistic problem at a distance,
Belong to a kind of novel airborne communication agreement.
1 frame video image is divided into muti-piece in ARINC818 agreement, every piece is packaged into 1 ADVB message, according to fixation
Time tranfer.It is as shown in Figure 1 to send frame timing.Ideally, video gets forwarded to destination from source, and the delay of every frame should
Equally.In fact, because of the reasons such as asynchronous clock, it may occur that different delay, here it is shakes, will cause video playing
It is unstable, such as video cardton, ash screen, reduce the experience sense of user.
Summary of the invention
The object of the present invention is to provide a kind of vibration control methods of Video transmission system based on ARINC818 agreement, dress
Set, for solve the problems, such as in the prior art aerial video shaken in transmission process cause it is jiggly.
In order to solve the above technical problems, the present invention proposes a kind of shake of Video transmission system based on ARINC818 agreement
Control method, comprising the following steps:
1) capacity that video data to be sent is stored in real-time detection buffer area, calculates the size of the capacity；
2) when lower limit value of the capacity lower than setting, increase a line vacant line in the image tail of present frame to be sent, when
When the capacity is higher than the upper limit value of setting, a line vacant line is deleted in the image tail of present frame to be sent；
3) picture frame of the increase or deletion a line vacant line is sent.
The present invention stores the capacity of video data to be sent by calculating in buffer area, compare whether the capacity exceeds setting
Upper limit value and lower limit value, according to present frame to be sent image tail delete or increase a line vacant line, guarantee send figure
As the stationarity of frame.
Further, the lower limit value is a quarter of buffer area total capacity, and the upper limit value is buffer area total capacity
3/4ths.
In order to solve the above technical problems, the present invention also proposes a kind of trembling for Video transmission system based on ARINC818 agreement
Dynamic control device, including detection unit and control unit, in which:
Detection unit is for storing the capacity of video data to be sent in real-time detection buffer area；
Control unit is used to calculate the size of the capacity, when lower limit value of the capacity lower than setting, works as to be sent
The image tail of previous frame increases a line vacant line, when the capacity is higher than the upper limit value of setting, in the image tail of present frame to be sent
A line vacant line is deleted, control sends the picture frame of the increase or deletion a line vacant line.
Further, the lower limit value is a quarter of buffer area total capacity, and the upper limit value is buffer area total capacity
3/4ths.
Detailed description of the invention
Fig. 1 is the transmission frame timing figure of ARINC818 agreement in the prior art；
Fig. 2 is the vibration control method flow chart of Video transmission system transmitter transmitting message；
Fig. 3 is the Video transmission system schematic diagram based on ARINC818 agreement.
Specific embodiment
A specific embodiment of the invention is further described with reference to the accompanying drawing.
For the shake for controlling ADVB message, ARINC818 agreement defines A1~D3 totally 12 grades.Wherein, D3 grade is most
Strictly, zero shake, C2 grade allow to shake in the form of vacant line between image, and non-jitter inside image, vacant line, which refers to, is scheming
Picture tail portion is additional, without any image data, for controlling the null of transmission timing.The line number of vacant line has default value, can
Dynamically to adjust.Therefore, the present invention is designed according to C2 grade.
As shown in Fig. 2, the present invention proposes transmitter transmission report in a kind of Video transmission system based on ARINC818 agreement
The vibration control method of text, comprising the following steps:
1) capacity that video data to be sent is stored in real-time detection buffer area, calculates the size of the capacity；
2) when lower limit value of the capacity lower than setting, increase a line vacant line in the image tail of present frame to be sent, when
When the capacity is higher than the upper limit value of setting, a line vacant line is deleted in the image tail of present frame to be sent；
3) picture frame for increasing a line vacant line or deleting a line vacant line is sent.
The corresponding above method, the present invention propose transmitter transmission in a kind of Video transmission system based on ARINC818 agreement
The jitter control apparatus of message, including detection unit and control unit, in which:
Detection unit is for storing the capacity of video data to be sent in real-time detection buffer area；
Control unit is used to calculate the size of capacity, when lower limit value of the capacity lower than setting, in present frame to be sent
Image tail increase a line vacant line, when the capacity be higher than setting upper limit value when, present frame to be sent image tail delete
A line vacant line, control send the picture frame for increasing or deleting a line vacant line.
Wherein, lower limit value is a quarter of buffer area total capacity, and upper limit value is 3/4ths of buffer area total capacity.
The present invention stores the capacity of video data to be sent by calculating in buffer area, compare whether the capacity exceeds setting
Upper limit value and lower limit value.When detecting lower than lower limit value, under the premise of constantly buffer area is written in video image, pass through increasing
Add vacant line to increase buffer capacity, that is, reduces the rate that video image is read from buffer area, make the existing picture number of buffer area
Rise according to amount；Similarly, when detecting higher than upper limit value, under the premise of constantly buffer area is written in video image, pass through deletion
Vacant line reduces buffer capacity, that is, increases the rate that video image is read from buffer area, make the existing image data of buffer area
Phenomena such as amount reduces, and guarantees the stationarity for sending picture frame, prevents video from Caton, ash screen occurs, improves the experience sense of user
By.
Specifically, Video transmission system as shown in Figure 3, including transmitter and jitter control apparatus, jitter control apparatus
Including detection unit and control unit, detection unit is for storing the capacity of video data to be sent in real-time detection buffer area；
Control unit is used to calculate the size of capacity, and when lower limit value of the capacity lower than setting, control transmitter is to be sent current
The image tail of frame increases a line vacant line, when the capacity is higher than the upper limit value of setting, controls transmitter in present frame to be sent
Image tail delete a line vacant line, control transmitter sends the picture frame for increasing or deleting a line vacant line.
The above description is only a preferred embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification,
Equivalent replacement, improvement etc., should be included within scope of the presently claimed invention.
