Broadcasting system based on VOIP (voice over internet phone)

The technical field of

[0001] the invention claims a based on voip phone broadcasting system.

Background technology

[0002] internet committee 5 is defined by the ip address type to be suitable for different capacity network and a flywheel type. The multicast message the destination address of the d type ip address range is from 224.0 0.0 to 239.255 255.255. Ring in the ip multicast data packet in the destination address is one of the is a group of

Form a group address. The information receiver are added to a group of inner and once after adding the flowing direction and address of data immediate begins to receive the transmission in the set of all members can be received data packet. In the multicast group members of the invention claims a dynamic host computer can be at any time adding and exiting the multicast group.

[0003] in many such as boiled under the condition of not only needs to field of the speaking user can listen and it has good; Or ltd direction of all staffs broadcasting information or whether to notice; Or is to claim ltd staff in operation period of the system as an eye health protection and so on the scene in accordance with it only needs to broadcast and the scene it can make use of voip phone to realize. Broadcasting is a pair of a method of using voip phone realizing broadcast function is as follows initiator of the session to a plurality of voip phone initiating the session by initiating transmission of audio information the call the voip receiving and playing the initiator and does not process the receiving part of any sound information. Existing technology does not the voip phone realizing broadcast function * be.

The content of invention

[0004] the invention is to solve the technical problem of one is to provide a based on voip phone broadcasting system to realize the voip phone carries out the broadcast.

[0005] this invention is realized like this:

Based on voip phone broadcasting system comprises a is used for initiating a voip phone and many is used for receiving the voip phone comprises the following steps:

Step 10 to the voip phone call of the multicast is set on the filled in the multicast address;

Step 20 while answering phone of the voip call multicast is set on the filled in the multicast address;

Step 30 sends the voip phone to multicast address transmitting the audio information;

Step 40 receives voip phone receiving multicast address of the audio information;

Step 50 voip phone the obtained sound information analyzing and playing the.

[0006] further the said audio information is real-time transmission protocol rtp data stream.

[0007] this invention has advantages as follows: The invention uses the existing of the voip phone to realize broadcast receiving and playing function and does not increase additional spending it can conveniently use all kinds of broadcasts scene.

Specification attached drawing

[0008] the lower part of the reference attached drawing of the embodiment of this invention is to further explain.

[0009] picture 1 is the invention claims a flow picture.

Specific implementing manner

[0010] as is shown in figure 1 the invention claims a based on voip phone broadcasting system comprises a is used for initiating a voip phone and many is used for answering telephone a voip. Of the present invention is applied to broadcast time firstly enters into step 101 the invention the voip phone call of the multicast is set on the filled in the multicast address of multicast address is used for initiating voip phone call of the multicast. Receives voip phone the method comprises the step 102 in the group broadcast paging is set on the filled in the multicast address the voip voice answering machine is filled in the step 101 in the same multicast address of voip phone the multicast address to perform monitoring. The step 103 initiated in voip phone the sound information and transmits it to the multicast address; V0ip telephone the voice information and transmits it to the multicast address the process of the voip phone of the communication process is similar to the field of people is that it is easy to understand the sending of voip phone can not receive any sound information. The audio information can be the spot the voip phone communication protocol in the normal use of the real-time transmission protocol rtp data stream. Receives voip phone the method comprises the step 104 from the multicast address is obtained sound information; Because initiation of the voip phone multicast address of voip phone and receiving multicast address of the same when the address the voip phone the sound information and transmits it to the multicast address after the network equipment will the voice message is sent to monitoring the multicast address of equipment namely the receiving of the voip phone is connected with telephone voip phone the multicast address and obtaining the sound information. At last step 105 of voip phone the obtained sound information analyzing and playing the process of the voip phone the call the voip call from the other of the obtained sound information analyzing and playing the process of similar. When the plurality of receiving a voip phone are all monitoring multicast address and obtaining sound information and playing it the utility model claims a voip call initiating the sound of the plurality of receiving telephone voip on playing the utility model claims a sound information the voip phone broadcasting.

[0011] although the above described this invention claims a specific implementing manner but not familiar the technical field of technical personnel to understand they are described the specific embodiment of the invention is a just and it is not used in the scope of this invention the limit of familiar the field the technical personnel in according to this invention the mental the equal to the modified and all to change the coverage of the invention claim said protecting in the range of.
