Based on the above-mentioned characteristic of view networking, one of the core concepts of the embodiments of the present invention is proposed, it then follows regard the association of networking View sends view networking address request from monitoring management platform to streaming media server, and the streaming media server sends address and rings It answers, both sides obtain communication channel by exchange address, finally allow streaming media server by the MAC of monitoring management platform Location sends PCTV resource to monitoring management platform.

Referring to Fig. 5, a kind of step flow chart of the embodiment of the method for acquisition PCTV resource of the invention, this method are shown It can be applied in view networking, the view networking includes monitoring management platform, streaming media server, and the streaming media server is deposited Contain PCTV resource.

In embodiments of the present invention, the monitoring management platform also known as MServer are responsible for all accesses in entire view networking Monitoring device unified management and other third party's monitoring systems docking service.

Streaming media server is to be acquired, cache, dispatch and transmit the service played depending on streaming media content in networking Device is the Key Platform for providing a user Video service.

PCTV is exactly telecomputer, the playing function of its existing TV, and has some functions possessed by computer, such as Communication receives the functions such as various information, word processing, management from network.The PCTV resource can be understood as PCTV user Information, as the organization of account, title, contact method, the business description being responsible for, presence etc. and PCTV believe Breath, such as organization's coding, organization's title.

Monitoring management platform needs periodically or non-periodically to manage the registration information and online behavior etc. of PCTV user Ground obtains the information of PCTV user, i.e. PCTV resource from streaming media server.The information content that PCTV resource generally comprises compares Greatly, using the 8F85 agreement transmission PCTV resource depending on networking traditional, there are many disadvantages.Firstly, because 8F85 agreement itself positions In quick, high-speed transfer, so needing to limit the data length transmitted every time, i.e., 52 bytes, Cai Nengbao can only be at most transmitted Demonstrate,prove transmission speed.When such agreement is used for transmission data volume big PCTV resource, in order to which the data packet for meeting 8F85 agreement is big Small limitation, PCTV resource can be split into a large amount of small data packets, and it is very low to will lead to network utilization in this way, transmit complete A PCTV resource, the time of required cost also can be long, reduce working efficiency；Secondly because 8F85 agreement regulation is each 52 bytes can only be transmitted, and the size of a complete user information has been over 52 bytes, so that monitoring pipe In the user information that the small data packets for the PCTV resource that platform is got every time include, lack the important informations such as organization, It is not a complete user information, so as to cause correct user information catalogue can not be shown in webpage front-end.

In view of this, a kind of method that the embodiment of the present invention proposes completely new acquisition PCTV resource, to solve above-mentioned use Depending on defect existing for networking 8F85 agreement transmission PCTV resource.As shown in figure 5, the method can specifically include following steps:

Step 501, the monitoring management platform sends view networking address request, the address to the streaming media server The first MAC Address of the monitoring management platform is carried in request；

It in embodiments of the present invention, is to transmit information by the view networked terminals number of communicating pair depending on networking 8F85 agreement , but as previously described, because PCTV resource data amount is larger, be not suitable for using 8F85 agreement, so acquisition can be passed through at this time The MAC Address of both sides transmits PCTV resource by end-to-end MAC Address.

Specifically, since monitoring management platform needs to obtain PCTV resource from streaming media server, therefore monitoring pipe pats Platform sends Address requests to streaming media server, and the first MAC Address of itself is carried in the Address requests.Because describedly Location demand signalling is short signaling, so the transport protocol used at this time is 8F85 agreement.

Step 502, the streaming media server sends address response to the monitoring management platform, in the address response Carry the second MAC Address of the streaming media server.

In embodiments of the present invention, in response to the Address requests, streaming media server is sent out to the monitoring management platform The second MAC Address of itself is given, in this way, communicating pair just has exchanged the MAC Address of itself, and is established by MAC Address logical Believe link.Because streaming media server has been known for the first MAC Address of monitoring management platform, the address sent at this time The signaling of response can be sent to monitoring management platform by the first MAC Address, can also pass through the terminal of monitoring management platform Number send.

In above-mentioned steps 501 and step 502, monitoring management platform and view networking streaming media server exchange both sides MAC Address, can be networked 8F85 agreement by view.

Step 503, the monitoring management platform sends the request for obtaining the first PCTV resource to the streaming media server Signaling, wherein the data volume of the first PCTV resource is greater than given threshold.

In embodiments of the present invention, after having exchanged the MAC Address of both sides, so that it may transmitting for PCTV resource is carried out, At this point, monitoring management platform is firstly the need of the demand signalling for sending acquisition PCTV resource.According to one data packet packet of 8F85 agreement The byte number 52 contained can classify PCTV resource.It is given threshold with 52, if comprising whole user information The data volume of PCTV resource is greater than 52 bytes, then is referred to as the first PCTV resource, will be comprising whole user information Less than 52 bytes of the data volume of PCTV resource, then be referred to as the 2nd PCTV resource.

Specifically, at this point, in the demand signalling that monitoring management platform is sent to streaming media server, it is desirable that the PCTV of acquisition Resource type is the first PCTV resource.

Step 504, the streaming media server according to first view networking protocol, the first of Xiang Suoshu monitoring management platform MAC Address sends the data packet of the first PCTV resource.

In embodiments of the present invention, because monitoring management platform request is the first PCTV resource, root is needed at this time It goes to transmit the first PCTV resource depending on networking protocol according to depending on networking first.Wherein, the first view networking protocol is to regard connection 8F95 agreement is netted, the core of the agreement is to carry out information transmission using MAC Address, and a data packet of the agreement can transmit 1480 A byte number, in this manner it is possible to solve problem when the first PCTV resource is transmitted by 8F85 agreement.

Preferably, the streaming media server is according to the first view networking protocol, the first MAC of Xiang Suoshu monitoring management platform Address sends the data packet of the first PCTV resource, comprising:

The first PCTV resource is divided into multiple data packets by the streaming media server, and is each data packet addition packet Head；Wherein, in the packet header, mark transmits the data packet using the first view networking protocol, and the packet header includes described The serial number of first MAC Address, second MAC Address and the data packet；

The streaming media server is according to the first view networking protocol, the first MAC Address hair of Xiang Suoshu monitoring management platform Send several data packets of the first PCTV resource.
