Embodiment
The embodiment of the vision signal display methods to the present invention and system is described in detail below in conjunction with the accompanying drawings.
With reference to figure 1, Fig. 1 show the vision signal display methods flow chart of one embodiment, comprises the following steps：
S10, the pause control instruction of vision signal is received, when every frame of vision signal starts to the pause control in system
Instruction processed is updated, and carries out pausing operation to vision signal according to the pause control instruction of renewal；
In above-mentioned steps S10, receive the pause control instruction of vision signal, and carry out relevant updates, pausing operation is
Unite as video control system.Above-mentioned video control system can be certain intelligent processing system, such as FPGA control systems；It is above-mentioned
Video control system receives the pause control instruction of vision signal during vision signal is shown, it suspends control instruction
Can be inputted by pressing the pause button of video control system, can also by press pause button on corresponding remote control or
Person's other modes input., can be with to display after video control system receives inputted vision signal pause control instruction
In vision signal carry out corresponding pausing operation, it is met the need that associated user is suspended or played to vision signal
Ask.
In one embodiment, the pause control instruction of above-mentioned reception vision signal, when every frame of vision signal starts
Pause control instruction in system is updated, and pausing operation is carried out to vision signal according to the pause control instruction of renewal
The step of before can also include：
Vision signal to be shown is received, and is judged in system with the presence or absence of pause control instruction；
If it is not, vision signal shown in then showing.
As one embodiment, above-mentioned reception vision signal to be shown, and judge in system with the presence or absence of pause control
It can also include after the step of instruction:
If Installed System Memory is suspending control instruction, pause behaviour is carried out to vision signal according to the pause control instruction
Make.
, it is necessary to which which kind of signal video control system shows in the present embodiment, can with to the video control system input phase
The vision signal to be shown answered, improve the practicality that above-mentioned video is shown.
S20, after renewal suspends control instruction, continue to the vision signal of current desired pause and start to store,
After storing a complete frame video signal, the repetition storage operating function of system default is closed；
In above-mentioned steps S20, the system for repeating to store operating function is stored and given tacit consent to above-mentioned vision signal
For video control system, above-mentioned video control system can be certain intelligent processing system.
In one embodiment, it is above-mentioned after renewal suspends control instruction, continue to the video letter of current desired pause
Number and start to store, after a complete frame video signal is stored, the step of closing the repetition storage operating function of system default
It can include：
After pause control instruction renewal, the initial signal of frame synchronizing signal in vision signal is obtained；
Stored since the initial signal, and whether the vision signal for judging to receive reaches a frame；
If so, close the repetition storage operating function of system default.
It is above-mentioned after pause control instruction renewal as one embodiment, obtain of frame synchronizing signal in vision signal
It can also include before the step of beginning signal：
Store instruction is received, and the vision signal in pausing operation is obtained according to the store instruction.
In the present embodiment, when vision signal normal play, i.e., without pausing operation when, the correlation of video operating system
The input and output of memory device are 0, are now not take up the bandwidth of video control system；Suspend when to above-mentioned vision signal
During operation, pause control instruction is updated at the initial signal of frame synchronizing signal in video signals, and carried out corresponding
Pausing operation, wherein it is possible to obtain the initial signal of frame synchronizing signal in vision signal, judge since the initial signal,
Whether storage reaches a frame；If it is not, then output is the vision signal do not suspended；If so, then output suspends vision signal, Ke Yibao
For card during the pause of vision signal, the vision signal that video control system is preserved includes a whole frame, so can be with
Stop the continuous storage to the halt signal, only need to constantly read the complete frame video signal stored, now display is corresponding
Memory device bandwidth shared by vision signal just only includes showing the bandwidth shared by above-mentioned pause vision signal, effectively reduces
Video control system occupied bandwidth, the bandwidth availability ratio and the stability of a system of video control system can be improved.
S30, during pause, show the vision signal of the storage.
Vision signal display methods provided by the invention, by receiving the pause control instruction of vision signal, and exist in time
The pause control instruction in system is updated when every frame of vision signal starts, and after renewal suspends control instruction, deposited
The vision signal of current desired pause is stored up, after a complete frame video signal is stored, closes the repetition storage behaviour of system default
Make function, and show the vision signal of the storage；Wherein only need to the vision signal storage in pause once, without continuous
The vision signal of pause needed for storage；And after the complete frame video signal of storage, it is temporary without being carried out to corresponding vision signal
When stopping storage operation, the storage read-write capability of required halt signal is completely closed, is reduced with this in video display process, pause behaviour
Make shared bandwidth, improve the bandwidth availability ratio of video control system, and it is that its storage system is brought to reduce high bandwidth and use
Unstability, and then improve corresponding video control system stability.
