Further, the multimedia system of present embodiment also can be utilized the signaling of signaling Control Server 705 direct all kinds of multimedia service of transparent transmission institute supported protocol between

terminal equipment

701a or 701b and all kinds of multimedia service server 704, thereby realized the transparent channel between

terminal equipment

701a or 701b and all kinds of multimedia service server 704, also can realize the multi-service fusion for the terminal equipment 701b that does not support Session Initiation Protocol, thereby improve the versatility that merges the multi-service scheme.

The four kind multimedia services cited with this paper background technology are example, and service server 704 as shown in Figure 7 just comprises following several: the uniform communication server that realizes the video monitoring server of video monitoring service, the videoconference server that realizes video conference business, the IPTV server of realizing the IPTV business and the unified communication service of realization.Correspondingly, terminal equipment 701a as shown in Figure 7 or 701b just comprise following several: as the video acquisition client of headend equipment, as Video Applications client and user terminal set-top box, the video acquisition that is integrated with headend equipment and subscriber equipment and the applications client of subscriber equipment and be integrated with headend equipment and the audio frequency transmitting-receiving bidirectional client of subscriber equipment.

(1), for video monitoring service, signaling Control Server 705 can be communicated with video monitoring server by the Session Initiation Protocol interface, video monitoring server also just is equivalent to video monitoring management platform, for support SIP at video monitoring server by SIP:

Signaling Control Server 705 receiver, videos are gathered the SIP call connection request signaling of client, the facility information that carries in the call connection request signaling that the video acquisition client is sent by service logic be converted to video monitoring server the video monitoring equipment channel number that can discern, and the call connection request signalling route that will carry the video monitoring equipment channel number is to video monitoring server; To the SIP that carries the video monitoring equipment channel number of video monitoring server feedback call out connect set up signaling and carry out reverse process after, respond the SIP that carries facility information to the Video Applications client and call out to connect and set up signaling;

For example, video monitoring gathers client such as DVR, can initiate to be used for requesting service registration when DVS reaches the standard grade sip user connects sets up demand signalling, for example Info message etc., carry the facility informations such as IP address of equipment of device id, dynamic assignment in this user's connection request signaling, these facility informations that carry in the Info message are simplified and be converted into the video monitoring equipment channel number that to be discerned by video monitoring server by signaling Control Server 705, and deliver video monitoring server processing etc.

The sip user of signaling Control Server 705 receiver, video applications client connects signaling, equipment user's information of carrying in user's connection request signaling that the Video Applications client is sent by service logic be converted to video monitoring server the video monitoring user profile that can discern, and the call connection request signalling route that will carry video monitoring user profile is to video monitoring server; To the sip user that carries video monitoring user profile of video monitoring server feedback connect set up signaling and carry out reverse process after, respond the SIP that carries equipment user's information to the Video Applications client and call out to connect and set up signaling.

Signaling Control Server 705 receiver, videos are gathered the SIP service request signaling of client, the switching value warning message and/or the stored information of carrying in the service request signaling with the transmission of video acquisition client, by service logic be converted to video monitoring server alert levels and corresponding warning sequence number and/or the memory capacity that can discern, the service request signalling route that will carry alert levels and corresponding warning sequence number and/or memory capacity then is to video monitoring server; According to the professional indication signaling that video monitoring server is responded, control switching equipment 702 is distributed to the video monitoring Media Stream of this video acquisition client with video monitoring server and sets up each Video Applications client and/or the memory device 703 that the user is connected;

For example, the video acquisition client has been initiated the service request signaling, carry for example switching value alarm signal such as smoke detector alarm signal in this service request signaling, and after passing to signaling Control Server 705, signaling Control Server 705 is with the switching value alarm signals such as for example smoke detector alarm signal of carrying in the service request signaling, be converted to video monitoring server appointment alert levels and the serial number that can unify to discern, report to the police and sequence number 002 as one-level, be given to video monitoring server again, respond the professional indication signaling that expression need be notified each Video Applications terminal according to video monitoring server then, control switching equipment 702 is distributed to the video monitoring Media Stream of this video acquisition client with video monitoring server and sets up each Video Applications client that the user is connected;

Again for example, the video acquisition client has been initiated service request, carry the stored information of Media Stream in the expression storing predetermined time period of need in this service request, signaling Control Server 705 automatic video quality code checks according to the video acquisition client, need the service request signaling of storing predetermined time period to be converted to video quality code check * scheduled time segment length=hard drive space capacity the expression video flowing, be given to video monitoring server again, respond the professional indication signaling that expression has enough hard drive space capacity according to video monitoring server then, and the storage policy that sets in advance in the signaling Control Server 705, control switching equipment 702 is distributed to correspondence position storage in the memory device 703 with the video monitoring Media Stream of this video acquisition client.

The SIP service request signaling of signaling Control Server 705 receiver, video applications client, the monitored object information of carrying in the service request signaling with the transmission of Video Applications client, by service logic be converted to video monitoring server the pairing Media Stream positional information of monitored object that can discern, the service request signalling route that will carry the pairing Media Stream positional information of monitored object then is to video monitoring server; Professional indication signaling according to the video monitoring server response, control switching equipment 702 is according to the Media Stream positional information, for setting up the corresponding video acquisition client that corresponding Video Applications client distribution that the user connects is connected with the video monitoring server apparatus for establishing and/or the video monitoring Media Stream of memory device with video monitoring server; Wherein, can control switching equipment 702 and initiatively call corresponding Media Stream, also can earlier the Media Stream positional information be fed back to video monitoring server and set up corresponding Video Applications client that the user connects, utilize the Media Stream positional information initiatively to obtain corresponding Media Stream by the Video Applications client again from switching equipment 702 according to the Media Stream positional information;

For example, the Video Applications client is initiated the service request signaling, and in this signaling, specify need obtain certain video acquisition client at 10 in the morning to captured Media Stream of 2 pm, signaling Control Server 705 detects pairing Media Stream video recording of at 10 in the morning to 2 pm index data automatically, and then navigate to this video acquisition client in 10 disk storage positions in the morning to captured Media Stream video recording place of 2 pm, after treating that then video monitoring server response expression allows to obtain the business indication of Media Stream video recording, the control switching equipment is according to the disk storage position that retrieves, for setting up corresponding Media Stream in the corresponding Video Applications client distribution memory device that the user connects with video monitoring server;

Again for example, because signaling Control Server 705 records online video acquisition client and Video Applications client, and online Video Applications client user, and signaling Control Server 705 also is provided with various media flow transmission strategies and storage policy, thereby after video monitoring server feeds back professional indication signaling at certain service request signaling, signaling Control Server 705 can be according to this business indication signaling, control switching equipment 702 transmits real-time video monitoring Media Stream for online Video Applications client and user thereof, video stream, can be online Video Applications client and user's transmitting multi-path video monitoring media thereof stream also according to further many pictures display strategy of indicating of professional indication signaling and/or round cut strategy etc.

Certainly, video monitoring server also may be communicated with signaling Control Server 705 by for example monitoring custom protocol interfaces such as proprietary protocol, at this moment, signaling Control Server 705 just needs further all kinds of SIP signalings to be carried out the protocol format conversion of monitoring between proprietary protocol and the Session Initiation Protocol.

Above-mentioned explanation all is at the terminal equipment 701a that supports SIP, then can carry out the route of transparent transmission mode according to signaling protocol class row according to aforementioned manner for the terminal equipment 701b that does not support SIP.

(2), for video conference business, signaling Control Server 705 can by H.248, H.323 or the Session Initiation Protocol interface be communicated with videoconference server, videoconference server also just is equivalent to the video conference controlled function among the MCU, for not supporting SIP but support the H.248 videoconference server of agreement:

The SIP call connection request signaling of 705 receiver, video collections of signaling Control Server and applications client and sip user connection request signaling, call connection request signaling and user's connection request signaling of video acquisition and applications client transmission are converted to H.248 protocol format, also the facility information that carries in the call connection request signaling that video acquisition and applications client are sent is converted to the overall channel number of video conference that videoconference server institute can discern by service logic, equipment user's information of carrying in user's connection request signaling that video acquisition and applications client are sent is converted to the video conference user profile that videoconference server institute can discern by service logic, and will carry the call connection request signaling of the overall channel number of video conference, the user's connection request signalling route that carries video conference user profile is to videoconference server; The calling that carries the video conference device channel number of video monitoring server feedback connected the user who sets up signaling, carries video conference user profile connect set up signaling and carry out reverse process after, respond the SIP that carries facility information to video acquisition and applications client and call out and is connected the sip user connection of setting up signaling and carrying equipment user's information and sets up signaling;

For example, initiate the SIP call connection request signaling that the expression requesting service is reached the standard grade and registered with video acquisition and applications client that hardware or software mode are realized, by signaling Control Server 705 SIP call connection request signaling is converted to H.248 protocol format, also with the IP address of equipment that carries in the call connection request signaling, facility informations such as PORT COM convert to the videoconference server that is equivalent to MCU the overall inner passage that can discern number, then will be H.248 the call connection request signalling route that carries overall inner passage number of protocol format to videoconference server, allow the overall inner passage number registration of this video acquisition and applications client in videoconference server after, can write down this video acquisition and applications client;

Again for example, initiate the sip user connection request signaling that expression request user reaches the standard grade and registers with video acquisition and applications client that hardware or software mode are realized, by signaling Control Server 705 sip user connection request signaling is converted to H.248 protocol format, also equipment user's information translation of carrying in user's connection request signaling is become to be equivalent to MCU videoconference server the expression meeting presiding user that can discern or the video conference user profile of meeting participating user, then will be H.248 the user's connection request signalling route that carries video conference user profile of protocol format to videoconference server, the user who allows this video acquisition and applications client in videoconference server as meeting presiding user or meeting participating user after, can write down the user of this video acquisition and applications client.

705 receiver, video collections of signaling Control Server and applications client carry the SIP service request signaling that meeting begins, the service request signaling of video acquisition and applications client transmission is converted to H.248 protocol format, also the meeting operation information that carries in the service request signaling that video acquisition and applications client are sent is changed this meeting and is operated pairing video conference user profile, and the H.248 service request signalling route that will carry video conference user profile is to videoconference server; The H.248 professional indication signaling that the expression of responding according to videoconference server allows this meeting to operate, control switching equipment 702 is operated pairing video acquisition and applications client distribution media stream for this meeting;

For example, for meeting this meeting operation of calling the roll, video acquisition and applications client as the meeting presiding user are sent SIP service request signaling, carry in this service request signaling the expression meeting call the roll operation at user's meeting operation information, after H.248 signaling Control Server 705 is converted to protocol format with SIP service request signaling, also will be carried on H.248 the service request signaling by roll-call video conference user profile and route to videoconference server by what the meeting operation information was converted to; After videoconference server is responded the professional indication signaling that expression allows to be called the roll, signaling Control Server 705 will be put video acquisition that the instruction of ring service indication signaling resolves into corresponding each user that called the roll respectively and applications client again so that can be by video acquisition and the applications client media stream of switching equipment 702 to other conference participations by roll-call user's video acquisition and applications client;

Again for example, for this meeting operation of meeting audio mixing, video acquisition and applications client as the meeting presiding user are sent SIP service request signaling, carry expression in this service request signaling and will need audio mixing user's meeting operation information, after H.248 signaling Control Server 705 was converted to protocol format with SIP service request signaling, also H.248 the video conference user profile of the need audio mixing that will be converted to by the meeting operation information be carried on the service request signaling and route to videoconference server; Respond the professional indication signaling of expression permission audio mixing when videoconference server after, signaling Control Server 705 is as the MCU of video conference, and all are participated in the video acquisition of current video meeting to control switching equipment 702 and the Media Stream of applications client output carries out being distributed to each video acquisition and the applications client that participates in the current video meeting again after many sound channels synthesize.In addition, signaling Control Server 705 also can be according to the storage policy of its internal configurations, and control will set up the video acquisition of calling connection as the switching equipment 702 of audio mixing crossview frequency function among the MCU and media flow transmission to the memory device 703 of applications client is stored.

Again for example, switch this meeting operation for the meeting picture, video acquisition and applications client as the meeting presiding user are sent SIP service request signaling, carry the expression meeting in this service request signaling and switch related user's meeting operation information, after H.248 signaling Control Server 705 is converted to protocol format with SIP service request signaling, also will be carried on H.248 the service request signaling by the video conference user profile that the meeting operation information is converted to and route to videoconference server; After videoconference server is fed back professional indication signaling, signaling Control Server 705 can be according to meeting site management strategy that sets in advance in this business indication signaling and the signaling Control Server 705 and/or video conference picture switchover policy, for passing the video conference Media Stream mutually between online some video acquisitions and the applications client transmission.

Certainly, videoconference server also may be communicated with signaling Control Server 705 by the SIP interface, and at this moment, signaling Control Server 705 does not just need all kinds of SIP signalings format conversion that carries on an agreement.

(3), for the IPTV business, signaling Control Server 705 can be communicated with the IPTV server by the custom protocol interface, the IPTV server also just is equivalent to the electronic programming inventory and selects server, for not supporting SIP but support the IPTV server of custom protocol:

Signaling Control Server 705 receives the sip user connection request signaling of user terminal set-top box, user's connection request signaling that the user terminal set-top box is sent is converted to the custom protocol form, also carry in user's connection request signaling that the user terminal set-top box is sent refresh the electronic programming listings request by service logic be converted to the IPTV server the list pane this shop that can discern, and user's connection request signalling route that will carry list pane this shop is to the IPTV server; To the IPTV server feedback carry user that the inventory version need upgrade connect set up signaling and carry out reverse process after, respond to video acquisition and applications client and to carry the sip user that upgrades version electronic programming inventory and be connected and set up signaling.

Signaling Control Server 705 receives the SIP service request signaling of supporting terminal set top box, the service request signaling that the user terminal set-top box is sent is converted to the custom protocol form, the IP Information On Demand that carries in the service request signaling that the user terminal set-top box is sent also, be converted to the pairing Media Stream of order video time and positional information by service logic, and user's connection request signalling route that will carry Media Stream time and positional information is to the IPTV server; Allow the professional indication signaling of program request according to the expression of IPTV server feedback, control switching equipment 702 is for setting up the video monitoring Media Stream of corresponding time and position in the respective user terminal set top box distribution memory device 703 that the user connects with the IPTV server;

For example, the user terminal set-top box is carried out play-on-demand program, program request current weather forecast information, and the SIP service request signaling that will carry IP Information On Demand sends to signaling Control Server 705, signaling Control Server 705 is converted to the custom protocol form with this service request signaling, automatically calculate then current latest network time and index latest network time the memory location of corresponding weather forecast information, the service request signaling that will carry the custom protocol of current latest network time and corresponding stored position then is sent to the IPTV server; According to the professional indication signaling of IPTV server feedback, the weather forecast Media Stream of the current latest network time that the corresponding stored position from memory device 703 will calculate is distributed to the user terminal set-top box then.

Certainly, the IPTV server also may be communicated with signaling Control Server 705 by the SIP interface, and at this moment, signaling Control Server 705 does not just need all kinds of SIP signalings format conversion that carries on an agreement.

(4) for unified communication service, but signaling Control Server 705 Session Initiation Protocol interfaces is communicated with uniform communication server, videoconference server also just is equivalent to unify telecommunication management signaling Control Server, for the uniform communication server of support SIP:

Signaling Control Server 705 receives the SIP call connection request signaling of audio frequency transmitting-receiving bidirectional client, the facility information that carries in the call connection request signaling with audio frequency transmitting-receiving bidirectional client by service logic be converted to uniform communication server the unified communication identifier that can discern, the call connection request signalling route that will carry unified communication equipment information then is to uniform communication server; To the SIP of uniform communication server feedback call out connect set up signaling and carry out reverse process after, respond SIP to audio frequency transmitting-receiving bidirectional client and call out to connect and set up signaling.

Signaling Control Server 705 receives the sip user connection request signaling of audio frequency transmitting-receiving bidirectional client, the user connected the user profile of carrying in the signaling by service logic be converted to uniform communication server the user right request that can discern, will carry user right requesting users connection request signalling route then to uniform communication server; The user right that carries in the sip user connection request signaling according to uniform communication server feedback is responded sip user and is connected and set up signaling and detect the value-added service information that this audio frequency transmitting-receiving bidirectional client user subscribes to possessing audio frequency transmitting-receiving bidirectional client that the user inserts authority.

Signaling Control Server 705 receives the SIP service request signaling of audio frequency transmitting-receiving bidirectional client, with the session of carrying in the SIP service request signaling to client information, for example be converted to Session Resources information such as bandwidth resources by service logic, the SIP service request signalling route that will carry Session Resources information then is to unified telephony server; The expression that the unified telephony server of foundation is responded has the professional indication signaling of enough Session Resources, and control switching equipment 702 transmits unified communication medium and flows between corresponding audio transmitting-receiving bidirectional client.

In addition, signaling Control Server 705 can also receive the professional indication signaling that expression that unified communication server initiatively sends pushes advertisement, and enumerate current all online audio frequency transmitting-receiving bidirectional client user inventories, directly control switching equipment 702 then and send advertising message; Signaling Control Server 705 can also receive the professional indication signaling that carries overlength Word message or video information that uniform communication server initiatively sends, and control switching equipment 702 was transmitted after overlength Word message or video information be divided into multistage.

Furtherly, because signaling Control Server 705 records online audio frequency transmitting-receiving bidirectional client and online audio frequency transmitting-receiving bidirectional client user, thereby after uniform communication server is fed back professional indication signaling, signaling Control Server 705 can be according to its inner connection control, interactive voice answering (Interactive Voice Response that is provided with, IVR) feature operation such as Voice Navigation, Word message is for passing the video conference Media Stream mutually between online some audio frequency transmitting-receiving bidirectional clients.

In addition, signaling Control Server 705 also can be according to the storage policy of its internal configurations, and control switching equipment 702 will be set up media flow transmission to the memory device 703 of calling out the audio frequency transmitting-receiving bidirectional client that connects and store.

Certainly, uniform communication server also may by H.323 or other protocol interfaces such as custom protocol interface be communicated with signaling Control Server 705, at this moment, signaling Control Server 705 just needs further H.323 all kinds of SIP signalings to be carried out or the conversion of the protocol format between other protocol interfaces of custom protocol and the Session Initiation Protocol.
