Method comprises the following steps：
Step S101, two adjacent frame display datas are compared, judge the adjacent whether complete phase of two frames display data
Together.
It is probably the same in continuous more frame data due to LED display playing pictures or lantern slide.If for example,
Adjacent two frame data are identical, then latter frame data can not be stored, it is necessary to when showing latter frame data, directly
Previous frame data are obtained to be shown.A frame data can then be stored and show two frame data.
The two adjacent frame display datas be compared can be judged by the receiving module or by
The control main frame is judged.
If step S102, present frame display data and former frame display data are incomplete same, present frame is shown into number
According to storing to memory, and its storage address is stored into the storage address list in the memory, if present frame is shown
Data are identical with former frame display data, then store the storage address of former frame display data into the memory
In storage address list, as the storage address of the present frame display data.
Further, the memory is nonvolatile memory.
The display data is stored to the nonvolatile memory and forms look-up table.Further, in addition to frame meter
Number is corresponding with the storage address of the display data to be stored into the nonvolatile memory.The frame count is aobvious for recording
The display order of registration evidence.
In an example, during whole LED display synchronous control system normal work, initiated to record life by sending module
Order, the display data that receiving module receiving front-end transmits, adjacent two frames display data is compared, if present frame and former frame
Display data is identical, then it is assumed that present frame is consistent with previous frame data.Deposited in nonvolatile memory corresponding to present frame
Store up the storage address that address is previous frame data.In an example, as shown in figure 4, the second frame display data T1, the 3rd frame show
Registration is according to T2, and the 4th frame display data T3, display data is the same, therefore T2 and T3 data are not stored in institute when data storage
State in nonvolatile memory, sequence of addresses is all to preserve A1 addresses when the 1st, 2,3 frame in addition.
In another example, the work that the display data content judges can be judged by the control main frame.
It is probably the same in continuous more frame data due to LED display playing pictures or lantern slide.And recorded when
Wait, be all to be sent by control main frame to receiving module, control main frame carries out judging to need each frame number sent before transmitting
According to content, according to only sending once, the number of repetition of repeating frame is recorded to be sent to receiving module same number of frames in the lump.And then
In the nonvolatile memory during data storage, same display data only stores one time.When off line plays further according to
Data duplication carried out per frame data numbers of repetition read the display data to be shown, so as to realize the compression of display data,
Send, storage and decompression are shown.
If step S103, described LED display synchronous control system is in off-line state, the receiving module produces frame
Synch command, the current display progress of off-line display pattern is transferred to by follow-up receiving module by the frame synchronization order,
The follow-up receiving module reads the address for the display data for being currently needed for display from local storage, then obtains in address
Display data, and the band carry LED display corresponding viewing area in control show.
If the LED display synchronous control system is in off-line state, off line play when receiving module voluntarily
Work, reads the data storage in local nonvolatile memory.The of LED display synchronous control system as shown in Figure 2
One receiving module 1 can produce field sync signal, and the frame count currently shown is passed to follow-up reception by frame synchronization order
Module.The current display progress of off-line display pattern is transferred to by follow-up receiving module by the frame synchronization order.Respectively connect

The storage address for the display data that previous frame needs, the display number in the address is read according to the storage address of obtained display data
According to being shown.In one embodiment, as shown in figure 4, as we know from the figure the 1st, 2, the storage of display data corresponding to 3 frames
Location is all A1, therefore the nonvolatile storage for data exported is T1；Corresponding non-volatile memories when 4 frame
Device address is A2, therefore the nonvolatile storage for data exported is T4.
Further, it is described to be transferred to the current display progress of off-line display pattern subsequently by the frame synchronization order
Receiving module include：The frame count is transferred to follow-up receiving module as frame synchronization order.

Whether adjacent two frame display datas are identical.
In the method for the present embodiment, adjacent two frame data are carried out in receiving module and are compared.When adjacent two frame number
According to identical, then judge that two frame data are consistent, it is not necessary to repeat to store.
For example, during the LED display synchronous control system normal work, sending module initiates record command, receives mould
Block receives the display data that sending module transmits, and adjacent two frames display data is compared, if present frame display data is with before
One frame display data is identical, then is judged as that present frame display data is consistent with former frame display data.Present frame shows number
According to the storage address that corresponding nonvolatile memory storage address is the former frame display data.
If step S102, present frame display data and former frame display data are incomplete same, present frame is shown into number
According to storing to memory, and its storage address is stored into the storage address list in the memory, if present frame is shown
Data are identical with former frame display data, then store the storage address of former frame display data into the memory
In storage address list, as the storage address of the present frame display data.
As shown in figure 4, it is data storage result schematic diagram in an example of the method for the present embodiment.In an example
In, as shown in figure 4, the second frame display data T1, the 3rd frame display data T2, the 4th frame display data T3, display data is the same,
Therefore T2 and T3 data are not stored in the nonvolatile memory when data storage, in addition sequence of addresses be the 1st,
2nd, A1 addresses are all preserved when 3 frame.For example, display data T4 is incomplete same then with former frame display data, number will be shown
Stored according to T4 into the nonvolatile memory, and preserve its storage address and formed into the nonvolatile memory and looked into
Look for table.
The method of the present embodiment also includes, and step S102a, stores the first frame count to the storage in the memory
In the list of location, first frame count is used for recording the display order of the display data.
Further, store to described corresponding with the storage address of the display data of the first frame count non-volatile is deposited
Reservoir, the first frame count described in first frame count are used for recording the display order of the display data.As shown in figure 4,
In one example, the frame count is from 0 start recording the first frame display data storage order, and the second frame display data is in terms of 1 frame
Number carry out record order, behind recorded by that analogy.First frame count and the display data storage address list
Corresponding lists are formed, form the look-up table of the display data.
Further, described in step S103 by the frame synchronization order by the current display progress of off-line display pattern
Being transferred to follow-up receiving module includes：First frame count is transferred to follow-up receiving module as frame synchronization order.
The follow-up receiving module reads from the local storage according to first frame count and is currently needed for showing
The address for the display data shown.
By judging above-mentioned receiving module the content of adjacent two frames display data, duplicate data can have without storage
Effect saves non-volatile memory capacity, the less data of storage is but shown more data.

When being recorded, led by controlling in the LED display synchronous control system normal work
Machine sends to receiving module, control main frame and before transmitting, first carries out judging to need each frame display data content sent, phase
Data with same frame are only sent once, and the number of repetition of repeating frame is recorded, and in the lump send number of repetition to the receiving module.
If step S1022, present frame display data and former frame display data are incomplete same, current display number is recorded
Frame index is corresponded to according to generation current display data, and it is one that current display data, which corresponds to frame index initial value, if present frame is shown
Data are identical with former frame display data, then former frame display data is corresponded into frame index value adds one.
The display data that the frame index is used to record the control main frame transmission corresponds to broadcasting time, also referred to as frame rope
