According to stream interface 1.
Wherein, due to being also dynamic connected mode between DEMUX and tuner in this method, therefore different numeral letters
After number coming, by the way that every group of data signal is divided into two groups of duplicate input paths, i.e., every signal wire has corresponded to two groups
Identical inputs path.This two groups of input paths are connected to demultiplexer using dynamic connected mode, and demultiplexer can be with
According to specific environment or which group input path of signal condition selection connection.State before responding after request instruction, you can choosing
Select and input path, then receive the data flow in the input path.
In another exemplary embodiment, as shown in figure 3, the demultiplexer that the present invention is provided after step S210
Data transmission processing method can also comprise the following steps
In step S310, in the input path for judging whether to receive highest priority in default time range
Data flow, if it has, then step S330 is performed, if it has not, then performing step S350.
Wherein, priority refers to that input path is arranged according to certain level order, and the priority in input path is got over
Height illustrates that the input path can be preferred, and is set by priority after each input path is ranked up, more can be effective
Use input path.The input path includes the different path of a plurality of priority, that is, referring to has a plurality of selectable path, according to
Different characteristics per paths can set different priority, and the priority for for example setting FE0 to data stream interface 1 is 1,
The priority of FE0 to data stream interface 2 be 2, FE1 to data stream interface 1 priority be 3, FE1 to TS4 priority be 4,
Here priority 1 is highest, and 4 be minimum, has 4 input paths.Thus, it is possible to select optimal defeated according to priority
Enter path.
Default time range refers to that time range is set in advance, in digital signaling system, due to signal data
Instantaneous variation, so default time range can not be excessive, otherwise may reduce experience effect during viewing program.For example it is pre-
If time range be 3 seconds, that is, illustrate to be judged as every 3 seconds once whether data flow can be received.If can be received in 3 seconds
Data flow, then perform step S330, otherwise performs step S350.
In step S330, the data flow in the input path of highest priority is received.
Wherein, due to data flow can be received in default time range by step S310, so directly receiving priority
Data flow in highest input path.
In step S350, according to priority order receives the data flow in input path successively, until being successfully received input
Data flow in path.
Wherein, due to failing to receive data flow according to step S310, so the order according to priority is needed, successively to defeated
Enter path to be judged, untill 3 seconds interior energies receive data flow.
It is preferred that, due to the high input path of priority, the possible short time, which has failure or other reasons, to cause temporarily
Data flow can not be received, then these input paths that can be high to priority at regular intervals between backstage are scanned,
Once it was found that data flow can be received, the more excellent input path can be directly switch to, user can also be reminded from group selection
The input path.
By method as described above, according to data signal to dynamic input path connection between demultiplexer, realize
Automatically select input path in a certain order according to request instruction, without by manually set can realizing route select
Select, the automation Selection effect in input path is effectively increased, so as to also improve Consumer's Experience.

Between path, the path between the recording arrangement of data stream interface 1 to the first etc..
The transmission channel in demultiplexer is connected with recording arrangement and playback equipment respectively for example, presetting, this says
Respectively there are two transmission paths between transmission channel and recording arrangement and playback equipment in bright demultiplexer.
In step S233, the path status of transmission path is obtained.
Wherein, the path status of transmission path includes taking, free time etc., and instruction can be obtained by state and obtains transmission road
The path status in footpath.
For example, the multimedia file just in playout storage (e.g., USB flash disk, hard disk etc.) instantly, it is to broadcast to illustrate transmission location
Equipment is put, the request instruction now received is zapping order, by the classes of instructions that zapping order is included is that program is played, passed
Defeated position is playback equipment, and the transmission location is occupied when this explanation receives zapping order, but now transmission path
For play multimedia file transmission passage be memory to playback equipment, the path status of the transmission path is occupied, and is changed
The transmission channel that platform is asked is data stream interface, the road of the transmission path (data stream interface to the path between playback equipment)
Footpath state is simultaneously unoccupied, is now accomplished by the path status that pre-sets according to transmission path to be operated.If in advance
The situation of setting is that the occupied transmission path can be switched, then can be first by memory to playback equipment when illustrating zapping
Transmission path disconnects, then by the transmission channel connection of data stream interface to playback equipment.
In step S235, the transmission channel of data flow is determined according to path status and classes of instructions.
The transmission state obtained according to step S233, the biography of data flow is determined with reference to the classes of instructions of former request instruction
Defeated passage.If the transmission channel is occupied and not changeable or can not connect, illustrating can not can not with the transmission channel
Set up connection.
By method as described above, according to transmission path set in advance, after request instruction is received, according to its instruction
Type, it is final to determine data flowing transmission channel by obtaining the status information of these transmission paths, realize transmission path

The transmission path of pass.
For example, the environment includes data stream interface 1, data stream interface 2 and file playback interface, transmission location includes broadcasting
Put equipment, the first recording arrangement and the second recording arrangement.According to the routing information pre-set, by the side of various path forms
Formula can be expressed as by form 1：
| Transmission path | Data stream interface 1 | Data stream interface 2 | File playback interface |
| Playback equipment | It can connect | It can not connect | It can connect |
| First recording arrangement | It can connect | It can connect | It can not connect |
| Second recording arrangement | It can connect | It can connect | It can not connect |
On the basis of form 1, if now receiving the request instruction of TV programme broadcasting, the change of transmission path information
Situation can be expressed as by form 2：
| Transmission path | Data stream interface 1 | Data stream interface 2 | File playback interface |
| Playback equipment | It is occupied | It can not connect | It can connect |
| First recording arrangement | It can connect | It can connect | It can not connect |
| Second recording arrangement | It can connect | It can connect | It can not connect |
In step S2353, transmission path is formed into transmission path set according to order set in advance.
Transmission path can preset an order, such as be set according to the order of priority, suitable according to this
All transmission paths are formed a transmission path set by sequence.
For example, referring to above table 1, according to static rule, in the case of no order or priority, it can select
Transmission path collection be combined into：
TV programme are played：(data stream interface 1, playback equipment)；
Multimedia file is played：(file playback interface, playback equipment)；
Record：(data stream interface 1, the first recording arrangement) (data stream interface 1, the second recording arrangement) (data stream interface
2, the first recording arrangement) (data stream interface 2, the second recording arrangement).
In step S2355, the transmission channel of data flow is determined according to path status in transmission path set.
Because the transmission path in transmission path set is sorted in a certain order, so now only needing basis
Path status in the transmission path set determines the transmission channel of data flow.
For example, having A, B, C to amount to 3 transmission paths in the set, according to the order of priority, A ranked first position, and B arranges
Two, C ranked third position, and it is occupied and not changeable for now ranked first the path A of position path status, ranked second the path of position
B path status is occupied but changeable, ranked third the path C path status of position for that can connect, thus, eventually selects
Routing footpath B, path A are due to occupied and not changeable without that can be chosen, although path C can be connected due to sequence rearward
