When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistented with the present invention.On the contrary, they be only with it is such as appended
The example of device and method being described in detail in claims, some aspects of the invention are consistent.
Firstly, brief description starting point of the present invention and thinking:
1, network model is established: by sub- equipment connection/combination as a kind of special equipment route network model；
2, it establishes routing node model: every sub- equipment being regarded as the routing section in above equipment route network model
Point: equipment routing node, and routed according to the parallel characteristics such as tables of equipment/multichannel equipment corresponding with the definition of signal processing parallel characteristics
The concatenate rule of node and limitation；

Software and hardware conflict will not necessarily occur for the sub- equipment of function, so that meeting the parallel of media play executes requirement.
Second, the present invention will be described in detail realizes sub- device resource allocation by establishing equipment routing node and concatenate rule
Method and concrete model:
(i) sub- device network model
Fig. 1 is the schematic diagram of a TV example neutron device network.The example is a kind of act of particular hardware configuration
Example, it is other similar.
It is laterally IEEE Std serial highway, any one TV service is combined by multiple sub- equipment in the sub- device network
It is common to complete, it is successively from left to right high frequency chieftain equipment, the sub- equipment of descrambling, demultiplex equipment, solution numeral equipment and output
Sub- equipment, 5 column boxes in corresponding diagram 1.Longitudinal is IEEE Std parallel highway, any one sub- equipment has multiple (being physically present multiple)
Or multichannel (physically one, but internal hardware has multiple accesses), it in most cases can be with concurrent working, i.e. in Fig. 1
As soon as each box be an entity or channel that the column correspond to sub- equipment, this, which shows how many box, corresponding number
Parallel channel.
When a new processing television signals are established, it is necessary to according to certain concatenate rule, suitable son be selected to set
It is standby, media play access is got through.
In another TV example, further includes that export in sub- equipment further include memory module, television recording may be implemented
With playback etc..
(ii) equipment routing node model
The control of any one equipment will be realized by equipment routing node in Fig. 1, the selection of sub- equipment be helped, with table
Illustrate equipment routing node for the routing node of high frequency head apparatus shown in 1:
Table 1
Such as table 1, an equipment routing node includes following a few parts:
Source node: source node is the input of equipment routing node: can be an equipment routing node, is also possible to most
The signal of beginning inputs；
Destination node: destination node is the output of equipment routing node: it can be next equipment routing node, it can also be with
It is final signal output；
Destination node state: including no equipment [X], idle [O] and three states of connection [connection serial number]；
Concatenate rule: according to the corresponding source node of input source, the corresponding destination node queue of input source is found, then basis
General rule and ad hoc rules, the selection target node in destination node queue.
Equipment routing node connected rule: the destination node of a upper device network network is the source of next device network network
Node.As shown in table 2 below, the partial target node of table 1 is the source node of 2 descrambler device routing node of table, if C_T_0 is in high frequency
It is purpose node in head apparatus routing node, and in descrambler device routing node is source node.
| C_T_0 | C_T_1 | S_0 | S_1 | |
| CAM_0 | [dbjective state] | [X] | [connection serial number] | |
| CAM_1 | [O] |
Table 2
(iii) concatenate rule model
The concatenate rule of broad sense is exactly to define set of rule how to realize according to input source node, passes through equipment routing node
Accessed path figure eventually finds the idle destination node that can be used.As shown in table 3 below, if input is the letter of source node 2
Number, it is searched in routing node path profile by certain rule, finally found that idle destination node: destination node 2.The present invention is total
All concatenate rules for having tied TV design basic demand and several general concatenate rules, and provide and how to realize that extension connects
Concatenate rule described in the method for connecing rule, general concatenate rule and extension concatenate rule, that is, technical solution of the present invention.
| Source node 1 | Source node 2 | Source node 3 | Source node 4 | |
| Destination node 1 | [connection serial number] | |||
| Destination node 2 | Idle [O] | |||
| Destination node 3 | [X] |
Table 3
1. basic demand
Shown in table 3 as above, source node and destination node collectively form a matrix, after input source is come in:
If there is no the source node, connection failure in matrix.
If active node, polling targets node queue, if there is the node of idle state, then to find target.It is no
Then, connection failure.
Concatenate rule is all on the basis of basic demand below, that is to say, that finds idle node meeting basic demand
Afterwards, it is also necessary to meet concatenate rule in detail below, can just think to find destination node.
2. concatenate rule
Rule 1: lateral mutual exclusion rule
Table 4
The principle of lateral mutual exclusion rule is: destination node can only be used by a source node, once it is some source node
It occupies, the destination node of other idle states, hereinafter referred to as idle destination node can only be selected.Shown in table 4 as above, for example, it is defeated
Entering source is source node 3, because destination node 1 occupies (connection status) by source node 2, horizontal exclusion shadow region, so can only
Select the destination node 2 in idle destination node.Many actual physical devices and physical vlan equipment all use this in TV
Rule: DEMUX, player, HDMI etc..
Rule 2: longitudinal mutual exclusion rule
Table 5
The principle of longitudinal mutual exclusion rule is: although supporting multiplexer channel on hardware, signal processing itself can only pass through one
A channel executes, and does not support multi-channel parallel to execute.Shown in table 5 as above, such as input source is source node 3, because of source node 3
There is a destination node 3 to be in connection status.According to longitudinal mutual exclusion rule, longitudinal repulsion shadow region, it may be assumed that source node 3 its
He requests, and can only fail.In TV, such scene is the demand that network flow-medium part plays scene, some piece of video stream
The same channel can only be used to send.In TV, such scene is the demand that network flow-medium part plays scene, some
Piece of video stream can only use the same channel to send.
Rule 3: intersect mutual exclusion rule
Table 6
The principle for intersecting mutual exclusion rule is: source node and destination node all cannot achieve parallel, monopolize.Shown in table 6 as above,
Such as input source is source node 3, because source node 3 has a destination node 1 to be in connection status, the region repelled is to hand over
Pitch shadow region.According to mutual exclusion rule is intersected, other requests of source node 3 can only fail.Other source nodes, such as source node 2
It is unable to selection target node 1.In TV, such scene is the selection of tuner.
Rule 4: specified path rule
Table 7
The principle of specified path rule is: some source node can only use or cannot use some destination node.As above
In table 7, source node 3 can only use destination node 1；Source node 2 cannot use destination node 2.In TV, such as due to hardware
Design or cost limitation, only CAM0 can descramble certain code stream TS0, this just meets specified path rule.
Rule 5: fixed batch of mutual exclusion rule
Table 8
The principle of fixed batch of mutual exclusion rule is: as long as certain class destination node has a node to use, most is mutually similar
Other source node and destination node be unable to using.In table 8 as above, because source node 3 uses destination node 1, lead to source node
1/2/3, it can not be used destination node 1/2/3, see shadow region.In TV, analog hardware resource is uniquely, only with a kind of
Simulation input source uses, and other simulation input sources can not be used, and belongs to this rule.
Fig. 2 is the hierarchical structure signal for the broad sense concatenate rule example that the sub- equipment of TV of the present invention includes including basic demand
Figure.Based on basic demand and above-mentioned 5 general concatenate rules, behind can be according to the design and evolution of hardware, easily
Carry out the extension of rule.
This extension can be the concatenate rule for inheriting front, such as: extension rule 1 and extension rule 3；It is also possible to directly
Independent connection rule under basic demand, such as: extension rule 2.
Fig. 3 is the sub- device network concatenate rule implementation diagram of TV of the present invention, i.e., the present invention implements sub- equipment money
The method of source distribution.By the specific concatenate rule application implementation in Fig. 2 to corresponding equipment routing node, since concatenate rule is
According to sub- equipment and signal processing actual pairing feature definitions, software and hardware will not necessarily occur for the sub- equipment being allocated successfully in this way
Conflict, to meet the execution requirement of parallel media broadcasting.
Above-mentioned sub- equipment actual pairing characteristic includes whether sub- equipment supports multichannel, could support up several roads etc., above-mentioned signal
