36 to be respectively stored into different storage spaces；Image converts and gray scale abstraction module 32,33 is used in image-receptive mould
The frequency that block 31 provides is respectively completed the under the field sync signal for the half such as 50HZ (or 60HZ) of the frame frequency of input video
The processing of one frame of video and the second frame of video, it is mainly by memory access control module 36 from dynamic RAM
Take out frame of video and complete the operations such as gamma conversion, correction, gray scale extraction, then will be complete by memory access control module 36
Frame of video after being extracted into image procossing and gray scale is stored into dynamic RAM；Enter between image-driven module 34,35
Row show synchronization and being respectively used to taken out by memory access control module 36 from dynamic RAM image procossing and
The first frame of video and the second frame of video after gray scale extraction are driven output；Frame shows that phase and duration adjustment module 37 are used for
Output selection signal is selected with the output to image-driven module 34,35, namely control image output multi-channel Multiplexing module
First frame of video of 38 selection driving outputs exported as the time span and starting/end point of output and selection driving the
Time span and starting/end point of two frame of video as output；Finally, will be with frame by image output multi-channel Multiplexing module 38
Frequency 100HZ (or 120HZ) carries out video frequency output.
Fig. 4 is referred to, it realizes that frame shows that phase and the process of duration regulation are shown for the reception card 30 of the embodiment of the present invention
It is intended to.In Fig. 4, VS1 is a display starting point (also display knot of A frames of B frames (such as corresponding second frame of video)
Spot), VS2 is the display end point (also another display starting point of A frames) of B frames；In order to which A frames is (such as corresponding
First frame of video), B frames export simultaneously, produce A, B frame selection signal as shown in Figure 4, low level (namely logical zero) when
Candidate A frames select B frames when high level (namely logical one) as output as output.During specific regulation, it can a) lock
Phase (namely B frames are relative to display starting point of A frames) is shown, only regulation shows duration；B) can lock display duration (namely
VS1 to VS2 length), only regulation shows phase；And display phase and duration can also c) be adjusted simultaneously.
Fig. 5 is referred to, it realizes that frame shows that phase and the result of duration regulation are shown for the reception card 30 of the embodiment of the present invention
It is intended to.The first frame of video and the view of the second frame of video that the left side exports in an alternating manner for content player, the right
For the first frame of video and the view of the second frame of video after the processing of card 30 is received shown in Fig. 3；In the reality shown in Fig. 1
In, the rectangle frame of Fig. 5 bends filling for example corresponds to live commercial frame of video, the spy of the corresponding insertion of unfilled rectangle frame
Different frame of video, so as to when LED screen is shown, realize that (namely frame is shown for the display starting point of the special video frame of insertion
Phase) and show that duration is adjustable.
In summary, the embodiment of the present invention propose realized on card is received in LED display frame of video show phase with
And the adjustable technical scheme of duration, solve live middle LED display as background applications, do not influenceing audience pair
The display phase of frame of video in LED display and can adjust for duration are realized on the basis of LED display impression, so as to
Solve different regions display and play different this problem of ad content.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, though
So the present invention is disclosed above with preferred embodiment, but is not limited to the present invention, any to be familiar with this professional technology people
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
For the equivalent embodiment of equivalent variations, as long as being the technical spirit pair according to the present invention without departing from technical solution of the present invention content
Any simple modification, equivalent change and modification that above example is made, in the range of still falling within technical solution of the present invention.
