Fig. 1 is a display processing method according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S102, determining whether the video signal is normal;
step S104, under the condition that the video signals are normal, controlling to adopt two memories to perform ping-pong operation on the video signals so as to output the video contents corresponding to the video signals frame by frame;
and step S106, controlling the two memories to stop ping-pong operation under the condition of video signal abnormality, and controlling one memory of the two memories to continuously output the image of the frame before the video signal abnormality.
It is easy to understand that the so-called ping-pong operation is that two memories alternately perform data read/write operation, when the first memory performs the write operation of a certain frame image, the second memory performs the read operation of the previous frame image, and when the first memory completes the write operation of the certain frame image, the two memories switch their operation, the first memory performs the read operation of the certain frame image, and the second memory performs the write operation of the next frame image.
The display processing method adopting the scheme comprises the following steps: determining whether the video signal is normal; under the condition that the video signals are normal, controlling to adopt two memories to perform ping-pong operation on the video signals so as to output video contents corresponding to the video signals frame by frame; and in the case of video signal abnormality, controlling the two memories to stop ping-pong operation, and controlling one memory of the two memories to continuously output the image of the frame before the video signal abnormality. The two memories are adopted to carry out the ping-pong operation of reading and writing in turn, so that the continuous output of the video content can be realized, and the pre-storage of one frame of image can be realized. When the video signal is abnormal, the ping-pong operation of the two memories is controlled to stop, so that the memory in the two memories, which stores the image of the frame before the video signal is abnormal, continuously outputs the image of the frame before the video signal is abnormal, and when the video signal is normal, the two memories still perform the ping-pong operation of the video signal to ensure the continuous output of the video signal.
Specifically, determining whether the video signal is normal includes: determining that the video signal is normal if all the detection conditions are satisfied, and determining that the video signal is abnormal if at least one of the detection conditions is not satisfied; the detection conditions include at least one of: the field frequency of the field synchronization is in a preset frequency range; the phase relation and/or the time sequence relation of the field signal, the line signal and the blanking signal meet the preset relation; the pixel clock signal is not interrupted.
In the case where the video signal is normal, the above-mentioned detection conditions are all satisfied, and by selecting one or more of the above-mentioned detection conditions as a basis for judgment, it is determined that the video signal is normal when all the detection conditions are satisfied, and it is determined that the video signal is abnormal when there is a detection condition that is not satisfied, which can conveniently and accurately make a judgment as to whether the video signal is normal or not.
Specifically, the display processing method further includes: under the condition that the video signal is normal, generating a reference synchronous signal according to the field synchronous signal; under the condition that the field synchronizing signal exists, carrying out field synchronization according to the field synchronizing signal; in the absence of the field sync signal, field synchronization is performed based on the reference sync signal.
Under the condition that the video signal is normal, the reference synchronous signal is generated according to the field synchronous signal, so that when the field synchronous signal is lost, the field synchronization can be performed according to the reference synchronous signal, the problem that the video cannot be played normally due to the loss of the field synchronous signal caused by the abnormal video signal can be solved, and the fluency and the stability of video playing are further improved.
Specifically, the synchronization period of the reference synchronization signal is greater than the synchronization period of the field synchronization signal; controlling field synchronization according to the field synchronization signal in the presence of the field synchronization signal, comprising: in case that the field sync signal indicates that the field sync operation is performed, the reference sync signal is controlled to be reset.

For example, as shown in fig. 2, in the present embodiment, a counter using a field sync signal as a reset mechanism is used to trigger the field sync pulse, the field sync signal triggers the sync pulse when counting to N, and the reference sync signal triggers the sync pulse when counting to P, where P > N, so that the reference sync signal is continuously reset as long as the field sync signal exists, and the field sync signal is always relied on for field synchronization, and the reference sync signal cannot be reset any more only when the field sync signal is lost, and the reference sync signal with hysteresis indicates that the field sync operation is performed.
Specifically, the display processing method further includes: determining whether the field sync signal is recovered under the condition that the control is performed according to the reference sync signal; under the condition of field synchronization signal recovery, determining whether the overlapping condition of the synchronization time of the field synchronization signal and the synchronization time of the reference synchronization signal meets a preset condition; and under the condition that the overlapping condition of the synchronization time of the field synchronization signal and the synchronization time of the reference synchronization signal meets a preset condition, controlling to carry out field synchronization according to the field synchronization signal.
The field synchronization is realized by adopting the reference synchronization signal under the condition that the field synchronization signal disappears, and when the field synchronization signal is recovered, the field synchronization is favorable for ensuring the video display effect according to the meeting place synchronization signal switched.
Specifically, the two memories are a first memory and a second memory, and the control adopts the two memories to perform ping-pong operation on the video signal, and the control method comprises the following steps: when the first memory is controlled to execute the writing operation of the target frame image, the second memory is controlled to execute the reading operation of the previous frame image of the target frame image; and when the first memory is controlled to execute the reading operation of the target frame image, the second memory is controlled to execute the writing operation of the frame image after the target frame image.
