Embodiment
In order to facilitate the understanding of the purposes, features and advantages of the present invention, below in conjunction with the accompanying drawings to the present invention
Embodiment be described in detail.
The present invention essentially consists in solution when many receiving modules are played in off line, common broadcasting fast scene poor synchronization
Problem, it is, for example, to be realized by following five steps：
Step (1)：Sequence
As shown in figure 1, when whole off line broadcasting control system normal connectivity works, sequentialize commands are initiated by sending module
To including multiple 1~n of receiving module receiving module array, receiving module 1 receives sequentialize commands (or the sequence of sending module
Signal), 1 is represented due to including sequence number such as sequence number in sequencing signal, then receiving module 1 can determine that oneself being No. 1 connects
Receive module, and produce comprising be incremented by sequence number (namely in the sequence number in original sequencing signal increase a numerical value, for example increase by 1)
Sequencing signal transmit backward；Receiving module 2, which is received, can determine that it oneself is No. 2 after the sequencing signal that receiving module 1 is passed over
Receiving module, and also generation is transmitted backward again comprising the sequencing signal for being incremented by sequence number；By this kind successively transfer mode, finally
N receiving module can determine that the sequence number of oneself, and each be stored.It is understood that as shown in Fig. 2 on to realize
Sequence is stated, 1~n of each receiving module can correspondingly be configured with sequencing unit 21 to determine the sequence number of oneself and produce comprising incremental
The sequencing signal of sequence number is transmitted backward.In addition, it is noted that sequence herein is primarily to determine each receiving module
Address (or position), in order to the execution of follow-up data saving step, thus 1~n of each receiving module sequence number simultaneously
Serial number is not limited to, as long as it is different；Each receiving module can certainly be determined using other modes
Address, for example with toggle switch, sending module is informed into 1~n of each receiving module address again afterwards, it also can reach
Identical purpose.
Step (2)：Data are preserved
When whole off line broadcasting control system normal connectivity works, each receiving module 1 electrically connected in cascaded fashion
~n can receive the view data that sending module is passed over.Data are sent by control main frame and preserve order, each receives mould
Corresponding view data is saved in respective non-volatile deposit by 1~n of block by respective data saving unit 23 (referring to Fig. 2)
In reservoir such as Flash (flash memory).In this process, vision signal of the sending module according to control main frame, send has in real time
Frame synchronizing signal, 1~n of each receiving module is synchronously preserved per frame image data into Flash, namely synchronous by frame storage image
Data are to respective nonvolatile memory.
Step (3)：Determine synchronous signal generating source under offline mode
When communication abnormality abnormal or between sending module occurs in the sending module in off line broadcasting control system, respectively
The field that individual receiving module will be unable to receive sending module transmission is wrapped to synchronize broadcasting (or online broadcasting), such as Fig. 3 institutes
Show, 1~n of each receiving module, which will be produced and is sent out one, compares bag, this, which compares, contains storage in step (1) in bag
Receiving module sequence number.1~n of each receiving module can receive the comparison that other receiving modules in addition to oneself are sent
Bag, and the receiving module sequence number in the receiving module sequence number of itself and the comparison bag received is compared：If itself connects
Receive module sequence number smaller than the receiving module sequence number in the comparison bag that receives, then continue transmission and compare bag, while the new comparison of reception
Bag is compared；If the receiving module sequence number of itself is bigger than the receiving module sequence number in the comparison bag that receives, do not retransmit
Compare bag.Finally, then the minimum receiving module of sequence number can be automatically determined as the synchronizing signal occurring source under offline mode.This
Place's receiving module 1 is present, so determine that receiving module 1 is synchronizing signal occurring source, if receiving module 1 is not present herein,
By receiving module 2 as synchronizing signal occurring source, if receiving module 2 is also not present, the like, with the reception that sequence number is minimum
Module is used as synchronizing signal occurring source.Defined herein rule for smallest sequence number receiving module as synchronizing signal occurring source,
But the present invention be not limited thereto or maximum sequence number receiving module as synchronizing signal occurring source or other sequence numbers
Receiving module be used as synchronizing signal occurring source.
Step (4)：Frame synchronization order is produced under offline mode

In frame synchronization order is exported into situation to other receiving modules by network interface, frame synchronization transmitting element 47 is needed by procotol
Form is packed to frame synchronization order.In addition, as shown in fig. 5, it is assumed that receiving module 1 is used as the synchronizing signal under offline mode
Occurring source, then receiving module 1 automatically generate frame synchronization order be provided from oneself use and transmit backward, 2~n of receiving module, which is received from, to be connect
Receive the frame synchronization order that passes over of module 1 and corresponding display logic is performed according to the frame synchronization order of reception.
Step (5)：Off line synchronously reads and shown
Have under offline mode after frame synchronization order, 1~n of each receiving module carries out work according to frame synchronization order
Make.As shown in fig. 6, each 1~n of receiving module parses frame synchronization order to obtain by respective frame synchronization resolution unit 61
Off line frame synchronizing signal and frame count M.Here, off line frame synchronizing signal is used for 1~n of synchronous receiving module data-reading unit
63 and data processing unit 65, frame count M, which are used to characterize, to be needed to read the M frame image datas stored in Flash.Read by data
The image data frame that unit 63 is read is taken to deliver to driver module after being handled through data processing unit 63 multiple with drive control
