Description
Technical field
The present invention relates to a kind of technical field of video monitoring, more particularly to a kind of TV row field signal timing adjusting method,
So as to eliminate the scintillation under signal source switching state.
Background technology
Many TV chips are believed in order to cost-effective without using frame buffer framework which improves television line at present
The design difficulty of number adjustment circuit.Traditional implementation method is the row field signal produced inside pio chip in no signal, and
Outside input row field signal is switched to when having detected signal input again.The method is realized simply, but due to OSD（on-screen
display）The row field signal of menu comes from row field signal time sequence adjusting circuit, thus switching different systems signal source or
OSD can be produced when having no signal to switch（on-screen display）Menu scintillation, visual impression is not good.
Therefore, it is necessary to a kind of new TV row field signal timing adjusting method in TV chip design, by this
The circuit that method is realized can still ensure that the stabilization output of TV row field signal in input signal handoff procedure.
The content of the invention
It is an object of the present invention to provide a kind of TV row field signal timing adjusting method, it is ensured that stablizing for TV row field signal is defeated
Go out, it is to avoid scintillation, improve visual impression.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of TV row field signal timing adjusting method, bag
Include following steps：
Step 1, original state：Parameters are configured according to the screen for using, stabilization is exported according to the initial parameter of configuration
Inside line synchronising signal, internal field sync signal, internal data useful signal and image data signal, while detection
With the presence or absence of the external video input signal of stabilization, if detecting the external video input signal of stabilization, internally field synchronization
Signal rising edge performs step 2 temporarily；Otherwise internally field sync signal rising edge repeats step 1 temporarily；
Step 2, line period synchronization：Internal line period is replaced with outside line period, if external video input signal is as good as
Often, internally field synchronization letter rising edge performs step 3 temporarily, and otherwise internally field sync signal rising edge performs step temporarily
Rapid 1；
Step 3, field duration synchronization：Change the internal field duration according to the outside field duration to accelerate field synchronization rising edge synch
Process, if external video input signal is without exception, internally field synchronization letter rising edge performs step 4 temporarily, otherwise internally

Step 4, genlocing process：The distance between the internal field synchronization rising edge of detection and outside field synchronization rising edge,
If both distances are less than certain threshold value, the change internal field duration causes that next internal field synchronization rising edge carrys out interim fields inside
Synchronous rising edge and outside field synchronization rising edge are substantially aligned, if external video input signal is without exception, internally field synchronization is believed
Rising edge to repeat step 4 temporarily, and otherwise internally field sync signal rising edge carrys out the interim external image number that will be exported
It is believed that number switching to image data signal and performing step 1；If both are more than certain threshold value or external video at distance
Input signal exception, internally field sync signal rising edge is next switches to interior view by the external image data-signal of output temporarily
As data-signal and perform step 1.
Wherein in an embodiment, presynchronization process is also included between the step 3 and step 4：Detection fields inside
The distance between synchronous rising edge and outside field synchronization rising edge, if both distances are less than certain threshold value, change fields inside week
Phase causes that next internal field synchronization rising edge carrys out interim fields inside synchronization rising edge and outside field synchronization rising edge is substantially aligned,
If external video input signal is without exception, internally field synchronization letter rising edge temporarily cuts the image data signal of output
It is changed to external image data-signal and performs the step 4, otherwise internally field sync signal rising edge comes described in interim execution
Step 1；If both are more than certain threshold value at distance, if external video input signal is without exception, internally field sync signal rises
Along repeating the presynchronization process temporarily, otherwise internally field sync signal rising edge performs the step 1 temporarily.
It is the inside line synchronising signal of the stabilization in the step 1, internal field sync signal, interior wherein in an embodiment
Portion's data valid signal and image data signal be according to a line number of effective points THV, line period THP being pre-configured with,
Line synchronising signal width TWH, row front porch width TFPH, effective line number TVV, field duration TVP, field sync signal width TWV,
