Table 2

Table 3

Table 4

MAC Frame Check Sequence(4Bytes)
	$.$.$.$

Table 5

It should be noted that, due to the existence of mac frame head, IP frame head, UDP frame head etc., therefore, that can pass through in MAC Address, IP address and user-defined UDP source/destination port number is one or more, perform the transmission of the Ethernet message frame of the application, particularly, such as can define: when MAC Address is 6 FF entirely, represent physical address broadcast; When IP section address is 4 FF, presentation logic address broadcast.By above-mentioned addressing system, thus in the process realizing the mutual of point-to-point, point-to-multipoint and broadcast, avoid the generation of the situations such as destination object mistake or confusion as much as possible, the transmission making message frame in time and accurately.

But based on the description of table 1-table 5, there is corresponding construction standard in the major part of Ethernet message frame, but for UDP message part, there is not concrete standard definition, therefore, the application by the definition of UDP message part and design, thus realizes the data transmission procedure that dynamic cinema special efficacy broadcasts system.

Two, the UDP message part of Ethernet message frame

In this application, the UPD data division of Ethernet message frame is specifically divided into 3 subdomains, be respectively: application controls territory (AppControlField), application processor territory (AppWhoFiled) and application data territory (AppDataField), specifically as shown in table 6:

Table 6

(1) application controls territory

Application controls territory is mainly used in carrying out UDP message message: function selects (FunctionCode), object channel selecting (ObjectChannel); Meanwhile, in order to ensure transmission accuracy and the fail safe of Ethernet message frame, can also realize confirming (ConfirmCode) and encryption (PassCode) function.Particularly, the structure for application controls territory is as shown in table 7 below:

Table 7

(2) processor territory is applied

Application processor territory is then for identifying the recipient of this Ethernet message frame, and how recipient should process, and concrete structure is as shown in table 8:

Table 8

Wherein, other forms in table 8(and the application) in the data being used for expression 1 byte. represent the data of 2 bytes, all the other the like.

General, the WhoAccept in application processor territory encodes and is used for confirming the recipient of this message, represents that row is selected with the position of row.Particularly, such as when the multidimensional seat of multiple MBOX(and correspondence and environmental effects broadcast equipment) when arranging a formation rectangle square formation, then, when WhoAccept is encoded to ff.ff, represent and entirely receive; During for xx.ff: represent that row receive; During for ff.xx: represent that row receives; During for xx.yy: represent that point receives; When being 00.00, be expressed as and need not receive broadcasting in the message (Ethernet message frame) that host computer sends, the message sent at MBOX slave station represents that only need broadcast computer main website receives.

General, the WhoReply in application processor territory encodes and is used for confirming the respondent of this message, represents that row is selected with the position of row.Equally for the rectangle square formation formed, when WhoReply is encoded to ff.ff, represents and entirely reply; During for xx.ff: represent row response; During for ff.xx: Num represents row response; During for xx.yy: represent some response; When being 00.00, expression need not be replied.

By adding the positional information of different row and columns in application processor territory, especially, when multiple MBOX forms matrix, can realize broadcasting host computer to MBOX in " entirely " mode, " OK " mode, " row " mode, and the question-answering mode of " point " mode or broadcast mode information interaction.

(3) application data territory

Storing different data messages in application data territory, by selecting with the function in application controls territory, the jointly controlling of object channel selecting etc., final transfer of data and controlling functions can be realized.

Owing to relating to operations such as the reading and writing of register, thus the register that the application may relate to is described.

Register type	Attribute register
		Status register	Read-only register

Parameter register	Read-write register
		Command register	Write-only register

Table 9

As shown in table 9, status register (DX), parameter register (FX) and command register (CX) three class may be related in the MBOX of the application, wherein, status register is read-only register, be merely able to by MBOX active or after receiving the order of broadcasting host computer, therefrom reading state parameter; Parameter register is read-write register, by MBOX active or after receiving the order of broadcasting host computer, therefrom can read existing operational factor, also can write operational factor wherein or upgrade existing operational factor; Command register is write-only register, by MBOX after receiving the order of broadcasting host computer, writes operating instruction wherein, to control the operation that multidimensional seat and environmental effects broadcast equipment.

(1) read register

Particularly, when the Ethernet message frame sent is the register data in order to read in MBOX, namely when described type of message mark represents that described Ethernet message frame is read register type, described data parameters is data storage location, described operated object mark is the mark of register to be operated, what then receive described Ethernet message frame broadcasts device controller in the register that described operated object mark is corresponding, reads the data corresponding to described data storage location.The form of the UDP message part of concrete message frame is as shown in table 11 below:

Table 11

From in upper table 11, first, what receive and reply this message frame broadcasts device controller, is determined respectively by the numerical value of " WhoAccept " and " WhoReply ".

Secondly, when function selection code (type of message mark) is for 0x1101, show that this message frame is for reading data in certain register of MBOX, particularly, the mark of this register is determined by the value of object channel selecting code, wherein, when object channel selecting code is 0, read the data in DX register, when object channel selecting code is 1, read the data in FX register.

Meanwhile, in application data territory, also added the initial address and data length that need the data read, and concrete " RegData " i.e. register data part being by vacancy, filling for using the data truly read.

In addition, after MBOX performs corresponding register data read operation, if this MBOX is also required to make response, then need to reply corresponding response message frame to broadcasting host computer.Relative to the Ethernet message frame received shown in table 11, in the response message frame generated, need the type (i.e. the numerical value of function selection code), recipient's mark, the respondent's mark that upgrade this message frame, and add the concrete data read in " RegData ".A kind of situation is as shown in table 12:

Table 12

Can notice from table 12: in function selection code, 0x1102 represents " the correct response to reading register manipulation " (ReadRegRightReply), namely shows that this MBOX correctly performs the read operation broadcasting host computer requirement.But when the read operation indicated by the Ethernet message frame broadcasting host computer transmission cannot be executed correctly, the various problem such as to there is not, data length does not exist than register address as shown in table 11, then MBOX should inform and broadcast host computer in the message frame of response, particularly, response message frame now can be as shown in table 13:

Table 13

Certainly, specifically which kind of mistake or error reason can also be shown in response message frame, such as can be realized by the concrete numerical value of " function selection code ", such as 0x1103 represents that the initial address of the register that needs read does not exist, and 0x1104 represents that data length exceeds maximum magnitude; Or can also pass through as shown in table 13, the code etc. that the corresponding error reason that writes direct in " error code " (ErrorCode) is corresponding.

(2) register is write

Particularly, when the Ethernet message frame sent is to write data to the register in MBOX, namely when described type of message mark represents described Ethernet message frame for writing register type, described data parameters is data to be written and data storage location, described operated object mark is the mark of register to be operated, what then receive described Ethernet message frame broadcasts device controller in the register that described operated object mark is corresponding, described data write to be written is corresponded to the space of described data storage location.The form of the UDP message part of concrete message frame is as shown in table 14 below:
