Specific embodiment
Illustrate presently filed embodiment below by way of specific specific example, those skilled in the art can be by this specification
Disclosed content understands other advantages and effect of the application easily.The application can also pass through in addition different specific realities
The mode of applying is embodied or practiced, the various details in this specification can also based on different viewpoints and application, without departing from
Various modifications or alterations are carried out under spirit herein.It should be noted that in the absence of conflict, the embodiment in the application
And the feature in embodiment can be combined with each other.
Current television network broadcast has been carried out data transmission using fiber optic network, has been based on this, the application introducing is used for
The PON network system of television network broadcast, and meet user bandwidth in conjunction with the PON network technology of big bandwidth or even super large bandwidth
Demand.
PON network, i.e. IP broadcast+PON network and the network system constructed.Since PON network is really that IP broadcast adds
The system of PON and GPON is mutually to melt superposition, is a channel of super large bandwidth, this channel brings video industry to user
Business, greatly promotes its quality, quantity, clarity and fluency are sufficiently ensured.
As shown in Figure 1, showing the schematic network structure of the PON network system in the embodiment of the present application.
The PON network system includes: server 101, the first PON network 102, IP network 103 and multiple PON STB
Terminal 104.
In some embodiments, the server 101, alternatively referred to as front end system, including IPTV server, for providing
The Video service of Internet Protocol Television；Optionally, it can support to provide the service of corresponding video flowing according to the program request of user terminal.
In some embodiments, the PON STB terminal 104, i.e. digital video switching box, are commonly called as " set-top box ", with
The development of technology, spreading out based on PON network can integrate light processing module and interface in PON STB terminal 104, so as to
Fiber optic network is directly connected to carry out high-speed communication.
The PON STB terminal 104 can be communicated with user terminal (such as TV), will acquire the view from server 101
Frequency stream is played out in TV.
As shown, on the one hand, the PON STB terminal 104 is established by the first PON network 102 with server 101
Two-way communication link can form Signalling exchange between PON STB terminal 104 and server 101 by the two-way communication link
To realize certain function.For example, service request is sent server 101 by PON STB terminal 104, the processing of server 101 should
Service request simultaneously feeds back PON STB terminal 104.
On the other hand, the PON STB terminal 104 is also communicated to connect by IP network 103 and server 101, this
Communication path is one-way/two-way transmission path, when unidirectional, that is, be only capable of server 101 to PON STB terminal 104 and carry out signal
Transmission.For example, server 101 carries out signal broadcast etc. to each PON STB terminal 104 by IP network 103.
In one embodiment, the PON network system further include: modulator is connected to the server 101 and PON
Between STB terminal 104, the video flowing of preset frequency is extracted in the baseband I P video data that can be used for transmitting in a network.Citing
For, the video flowing of the preset frequency can be the video data played in user demand viewing channel.
In one embodiment, settable first optical multiplexer (in Fig. 1 between server 101 and the first PON network 102
It is not shown), to cope with the data interaction between a large amount of PON STB terminals 104 and server 101.Similarly, optionally, in server
It may also set up the second optical multiplexer 105 between 101 and IP network 103, to cope with server 101 to a large amount of PON STB terminals 104
Transmission of video.
Optionally, also settable first image intensifer (Fig. 1 between first optical multiplexer and the first PON network 102
In it is not shown), for carrying out the amplification of optical signal；Similarly, optionally, second optical multiplexer 105 and IP network 103 it
Between may also set up the second image intensifer (not shown in Fig. 1), for carrying out the amplification of optical signal.
In some possible embodiments, the capacity of first PON network 102 be selected from 2.5G~10G, 10G~25G,
25G~50G or 50G~100G.
Specifically be, it is preferred that the capacity of first PON network 102 can be in 25G or more, such as
25G, 50G, 100G etc., to realize the first PON network 102 transmission of two-way 25G or more.Specifically, 101 pairs of server letters
Number source is encoded, and TS over IP packet is ultimately formed, and can be sent directly to the first optical multiplexer or be converged by standard IP
Network transmission is to the first optical multiplexer, because the total business outlet of PON broadcast system can reach 25Gbps and band above, in reality
When the networking of border, it can avoid inputting the instantaneous burst flow problem generated due to multiport completely using the first PON of 25G or more.
In an embodiment, the capacity of the IP network 103 is selected from 2.5G~10G, 10G~25G, 25G~50G or 50G
~100G.
Specifically, in the capacity of first PON network 102 in the case where 25G or more, it is preferred that institute
The capacity for stating IP network 103 can also be corresponded in 25G or more.
Although it is further to note that in the above-described embodiments, illustrating the PON network for preferably passing through 25G or more capacity
Carry out the two-way and/or unidirectional optical signal interaction between server 101 and PON STB terminal 104, still, not as
The capacity of limit, the first PON network 102 and IP network 103 can be changed according to actual needs, be adjustable.
Referring to Figure 2 together, server 201, the first PON network 202 and the PON in the application specific embodiment are shown
The attachment structure schematic diagram of STB terminal 204.
As shown, in the present embodiment, the server 201 is through the first optical multiplexer 203 and the first image intensifer 205
It is connected to the first PON network 202, includes connected OLT and ONU in the first PON network 202, each ONU is separately connected each PON
STB terminal 204, then user terminal 206 is connected to by PON STB terminal 204, such as TV, PC, mobile terminal (such as intelligent hand
Machine, tablet computer etc.).
From illustrating as it can be seen that first PON network and IP network are functioning in parallel for above-described embodiment；And it is optional,
It is the relationship mutually protected between first PON network and IP network；When the first PON network breaks down, IP network replaces it
Work；When IP network breaks down, the first PON replaces its work, to ensure normal communication and business demand.
As shown in figure 3, showing the PON network system business processing flow schematic diagram in the embodiment of the present application.
In the present embodiment, show that server requests to provide the service of corresponding video flowing according to PON STB terminal traffic
Journey, in actual scene, the scheme of the present embodiment can be used for realizing the telecast demanding service of user.
The process flow includes:
Step S301:PON STB terminal generates service request and is sent to server by the first PON network；
Step S302: the server is according to service request to corresponding PON STB terminal authentication；
Wherein, whether such as PON STB Termination ID in the authentication i.e. authentication service request has the corresponding business and asks
The user right asked, such as the permission etc. that VIP user just has.
Step S303: if the authentication is passed, by the first PON network send notice to PON STB terminal with inform its
Predetermined multicast address obtains the video flowing of the corresponding service request.
Specifically, user terminal can be in the video flowing of the service request to be received such as the predetermined multicast address.
It is understood that server refuses offer service if authentication does not pass through.
Step S304: the server broadcasts the video flowing of the corresponding service request to corresponding PON by IP network
STB terminal.
User terminal is after receiving the video flowing, so that it may carry out normal play.
So far, the process of telecast demanding is completed.
