Step 101: content viewing apparatus adds the group.
At first, so-called content viewing apparatus adds the group, is meant the incidence relation of setting up between content viewing apparatus and the group, carries out the preparation that Play Control is shared.Wherein, the content viewing apparatus mode that adds the group has following two kinds: the passive adding of content viewing apparatus and initiatively add dual mode:
One, passive adding mode
The distribution of services device sends group's message that joins request by the E3 interface to content viewing apparatus, receive that group that content viewing apparatus returns adds response message after, thereby realize content viewing apparatus is added the group; Wherein, the distribution of services device is to join request after the message getting access to group that group manage apparatus sends by the E1 interface, further sends group's message that joins request to content viewing apparatus.Can claim this mode to be: the passive adding mode of content viewing apparatus.
Two, active adding mode
The distribution of services device receives group that content viewing apparatus the sends message that joins request by the E3 interface, returns the group to content viewing apparatus and adds response message, shares the control group thereby content viewing apparatus added.
Further, group's message that joins request can be carried the group's information that need to add, wherein, independently build group process according to whether existing, there are two kinds of following situations in above-mentioned group's information: one, have group process of independently building: group manage apparatus sends the group by the E1 interface to the distribution of services device in advance and sets up request message, and the distribution of services device is handled this group and set up request message, creates and shares the control group, send the group to group manage apparatus and set up response message, finish group's foundation.Wherein, this group set up and can carry the group in the request message and set up indication information, permission or (for example do not allow to join this list information of sharing content viewing apparatus sign of control group, play operation authority information, which content viewing apparatus has the Play Control operating right, or which content viewing apparatus does not have the Play Control operating right), the content source information of this group (for example IPTV programme content sign).This sets up request message can adopt HTTP message, and modes such as sip message realize.Owing under this situation, successfully set up the group in advance, therefore group's information of carrying in the above-mentioned message that joins request is group's information of having existed (for example, Qun identification information etc.).Two, do not exist and independently build group process: new shared control group is created in group's indication that joins request in the message, and what need to add group is the group of this new establishment.In this case, the group joins request the group information of carrying in the message for creating the indication information of new shared control group.
Further, group's message request of can also carrying that joins request adds group's content viewing apparatus information, and for example the content viewing apparatus identification information can carry a plurality of content viewing apparatus information.
Further, group's message that joins request can also be carried the request initiator information, for example group manage apparatus identification information, or content viewing apparatus identification information.
Further, group's message that joins request can be carried the distribution of services device information, for example the distribution of services device identification information.
Further, group's message that joins request can also be carried the content viewing apparatus control information, is used for the control content viewing apparatus and joins watching of certain content automatically.
Further, group's message that joins request can also be carried Play Control power information, be used to indicate content viewing apparatus, may or indicate all content viewing apparatus all to have Play Control power for the sign of some specific content viewing apparatus with Play Control power.
Further, group's message that joins request can also be carried group's indication information that joins request, and is used to represent that this message is specially group's message that joins request.
Above-mentioned, control group's message that joins request can be by realizations such as HTTP request message, SIP Message message, SIP Info message, SIP INVITE, SIP REFER message.Of particular note, related group in the present embodiment can be a kind of explicit group, and clear and definite group's information is promptly arranged, and for example has the sign of sharing the control group etc.; Also can be a kind of group of implicit expression, promptly there is not clear and definite shared control faciation to close information, there is not group identification, it is the specific media content that the instruction content viewing apparatus need be watched, so-called specific media content can be direct media content information, and for example IPTV programme content sign also can be indirect media content information, be reference for example with certain content viewing apparatus, the identical media content that request watches this content viewing apparatus to watch.
Step 102: the distribution of services device carries out Play Control and prepares.
Add in group's the process at above-mentioned steps 101 content viewing apparatus, the distribution of services device need be finished the preparation that Play Control is shared.Wherein, whether independent at the media content that each content viewing apparatus in the group is watched, correspondingly, the realization that Play Control is shared has two kinds of basic modes: Media Stream independent mode and Media Stream interrelational form;
One, Media Stream independent mode
The media content that content viewing apparatus is watched is independent, there is not incidence relation between the Media Stream of promptly watching separately, content viewing apparatus is independently to obtain media content separately, for example independently obtain IPTV business program content separately, the media content that each content viewing apparatus is watched can be to provide module to provide by different contents.Under this mode, need under the control of distribution of services device, finish these the sharing of Play Control operation of Media Stream independently;
Two, Media Stream interrelational form
The media content that each content viewing apparatus is watched provides module to provide by same content, there is incidence relation between the Media Stream of watching separately, for example, be on the basis of same content source, duplicate distribution (may pass through processing such as transcoding therebetween, for example be converted to another kind of audio/video coding mode from a kind of audio/video coding mode, or the image size changes etc., but the media content of watching itself is identical, and the Media Stream that this content source can be provided is called with reference to Media Stream).Under this mode, need under the control of distribution of services device, act on this content in the Play Control operation set with a plurality of content viewing apparatus correspondences module is provided, promptly concentrate to act on this, thereby realize sharing of Play Control operation with reference on the Media Stream.
The preparation that Play Control is shared is described respectively under the dual mode below.
One, Media Stream independent mode
This mode further can be divided into Play Control ways of distribution and play control proxy mode.Wherein,
1, the Play Control ways of distribution
The Play Control ways of distribution is the Play Control operation that adding group's the content viewing apparatus with Play Control power can be carried out the media content of oneself watching, the sharing operation device detects the Play Control operation back of this content viewing apparatus and triggers sharing of Play Control, sends to the distribution of services device and shares the Play Control operation requests.In the distribution of services device, the Sharing Management module is determined the shared Executive Module of content viewing apparatus correspondence according to the content viewing apparatus that adds the group, sets up the incidence relation of sharing Executive Module and group.When receiving the shared Play Control operation requests of sharing operation device, the Play Control operation is distributed to the shared Executive Module of the other guide viewing apparatus correspondence that adds this group, carry out the Play Control operation respectively by the shared Executive Module of each correspondence.So realize, the media content that the content viewing apparatus of other in the group is watched has carried out same Play Control operation.
The sharing operation device can be to initiate the Play Control operation at content viewing apparatus, or in the Play Control operation implementation, or the Play Control operation complete after, detect the Play Control operation, and trigger sharing of Play Control.
Sharing of above-mentioned Play Control, can be regarded as a kind of passive Play Control shares, promptly when the media content generation Play Control operation that certain content viewing apparatus is watched, trigger sharing of Play Control, by the distribution of Play Control operation, the media content that other guide viewing apparatus in the group is watched is carried out same Play Control operation.For example, comprise content viewing apparatus A, B, C in the group, suppose that A has Play Control power, the pairing user of A carries out and changes the platform operation, the sharing operation device of A detect A change platform operation after, trigger sharing of Play Control, send shared Play Control operation requests to the distribution of services device, B in the distribution of services device, the shared Executive Module of C correspondence are carried out Play Control operation separately respectively, so realize, the media content that the content viewing apparatus of other in the group is watched has carried out same Play Control operation.
In addition, the content viewing apparatus that does not possess Play Control power, can be in the process that adds the group, receive the Play Control power indication that the distribution of services device sends, be used to indicate whether to shield user's Play Control operation requests, wherein, this Play Control power indication can send to content viewing apparatus, be used to notify the not Play Control operation requests of process user of this content viewing apparatus, do not send the Play Control operation requests when promptly receiving user's Play Control operation requests to content providing device, the content that also can directly send in the content viewing apparatus corresponding service dispensing device provides module, and being used for content of announcement provides module not carry out the user's of content viewing apparatus transmission Play Control operation requests.
Shared Executive Module can be directly carries out Play Control to the Media Stream of content viewing apparatus, for example, directly the content to the content viewing apparatus correspondence provides the module request to carry out the Play Control operation, also the Play Control operation requests can be sent to content viewing apparatus, finish the Play Control operation by content viewing apparatus, be that content viewing apparatus is received from after the Play Control operation requests of sharing Executive Module, provide module transmission Play Control operation requests to content again.
Its handling process is as described below:
Distribution of services device contents processing viewing apparatus adds in the process of sharing the control group, being the distribution of services device sends group's message that joins request by the E3 interface to content viewing apparatus, receive that the group that content viewing apparatus sends adds response message, or the distribution of services device receives group that content viewing apparatus the sends message that joins request by the E3 interface, recorded content viewing apparatus and group's incidence relation on the distribution of services device, and definite sharing operation device that adds this content viewing apparatus correspondence of group, detect the Play Control operation of the media content that content viewing apparatus watches by E2 interface indication sharing operation device, and when detecting the Play Control operation, send shared Play Control operation requests to the Play Control management devices.In this step, the distribution of services device can determine to add the shared Executive Module of this content viewing apparatus correspondence of group, foundation concerns the Play Control of the media content that this content viewing apparatus is watched, when sharing owing to the Play Control operation triggering Play Control of other content viewing apparatus with box lunch, shared Executive Module to this content viewing apparatus correspondence sends the Play Control operation requests, and the media content that makes this content viewing apparatus watch carries out same Play Control operation.
In this step, if this content viewing apparatus does not possess the Play Control power of shared Play Control, the distribution of services device can be indicated this content viewing apparatus shielding user's Play Control operation requests.The distribution of services device can carry this indication information by the E3 interface in the group that content viewing apparatus sends joins request message, or after the group that the contents processing viewing apparatus sends by the E3 interface joins request message, in content viewing apparatus transmission control group adding response message, carry this indication information by the E3 interface, perhaps send other message of carrying this indication information to content viewing apparatus by the E3 interface.Perhaps, distribution of services device (specifically being the Sharing Management module) directly indicates the content of this content viewing apparatus correspondence that module shielding user's Play Control operation requests is provided, i.e. the user's that sends of contents processing viewing apparatus Play Control operation requests not.
2, the play control proxy mode
The play control proxy mode is to add in group's the process at distribution of services device contents processing viewing apparatus, to the content viewing apparatus of Play Control power is arranged, determine the sharing operation device of this content viewing apparatus correspondence, when the user of content viewing apparatus asks to carry out the Play Control operation, share the Play Control operation requests to the transmission of distribution of services device by the sharing operation device of correspondence.In the distribution of services device, the Sharing Management module is according to the content viewing apparatus that adds the group, Play Control relation between the Media Stream that shared Executive Module of foundation and content viewing apparatus are watched, and the shared Play Control operation requests that Executive Module receives the transmission of sharing operation device is shared in indication, this shared Play Control operation requests is affacted the Media Stream of each content viewing apparatus correspondence, carry out the sharing of Play Control of each Media Stream.
Under this play control proxy mode, each content viewing apparatus shields user's Play Control operation requests under the indication of distribution of services device, sharing operation device by correspondence receives the also Play Control operation requests of process user, or content viewing apparatus is with the user's that receives Play Control operation requests, send to corresponding sharing operation device, rather than directly carry out (directly carrying out the Play Control operation) by original mode to the content providing device request by content viewing apparatus.After the sharing operation device receives the Play Control operation requests, send to and share Executive Module agency execution, promptly by sharing the media content that Executive Module affacts each content viewing apparatus correspondence again.
Sharing of above-mentioned Play Control, the sharing of Play Control that can regard a kind of active as, not being the media content generation Play Control passive triggering of when operation that certain content viewing apparatus is watched, is initiatively to send to share the Executive Module unified agent and carry out, to finish sharing of Play Control.For example, content viewing apparatus in the group comprises A, B, C, wherein, suppose that A has Play Control power, when asking to carry out, the user of A changes the platform operation, the sharing operation device of A correspondence receives this and changes the platform operation requests, this is changed the platform operation requests send to A in the distribution of services device, B, the shared Executive Module agency of C correspondence carries out, because the Play Control of having set up between the Media Stream that shared Executive Module and content viewing apparatus watch in distribution of services device inside concerns, this can be changed the media content that the platform operation requests affacts each the content viewing apparatus correspondence in the group, promptly affact A, B, on the media content of C correspondence, thereby realize content viewing apparatus A, B, the platform that changes of C is operated.
The content viewing apparatus that does not possess Play Control power, can be in adding shared control group process, under the control of Sharing Management module, do not set up the correspondence of sharing operation device, or the sharing operation device of correspondence sends when sharing the Play Control operation requests execution of shared Executive Module refusal.
The Media Stream that shared Executive Module can directly be watched content viewing apparatus carries out the Play Control operation, for example direct content to the content viewing apparatus correspondence provides the module request to carry out the Play Control operation, also the Play Control operation requests can be sent to content viewing apparatus, finish the Play Control operation by content viewing apparatus, promptly provide module to send the Play Control operation requests by content viewing apparatus to content again.
Wherein, the sharing operation device can have a plurality of, corresponding different respectively content viewing apparatus, but only there is a shared Executive Module, the shared Play Control operation requests of a plurality of sharing operation devices all sends to this shared Executive Module, is carried out the Play Control operation of each the self-corresponding media content of all the elements viewing apparatus in the group by this shared Executive Module.Wherein, content viewing apparatus is a plurality of, the media content that each content viewing apparatus is watched is independently, a plurality of independently Media Streams are promptly arranged, shared Executive Module writes down the Play Control relation of these Media Streams, when the Play Control operation requests is shared in the sharing operation device transmission of the content viewing apparatus correspondence with Play Control power, share Executive Module and carry out the Play Control operation at the Media Stream of all content viewing apparatus.
The play control proxy mode is by by same shared Executive Module all Media Streams in the group being carried out the play control proxy operation, under the control of Sharing Management module, with the shared Play Control operation requests of sharing operation device, send to and share the execution of Executive Module unified agent.
Its handling process is as described below:
Distribution of services device contents processing viewing apparatus adds in group's the process, being the distribution of services device sends group's message that joins request by the E3 interface to content viewing apparatus, receive that the group that content viewing apparatus sends adds response message, or the distribution of services device receives control group that content viewing apparatus the sends message that joins request by the E3 interface, recorded content viewing apparatus and group's incidence relation on the distribution of services device, determine to share Executive Module, and the sharing operation device of definite this content viewing apparatus correspondence, Play Control operation by E3 interface instruction content viewing apparatus shielding user, the sharing operation device that changes into by correspondence receives processing, or indicates the Play Control operation requests with the user to send to the sharing operation device.This can be to carry this indication by the E3 interface at the distribution of services device in the group that content viewing apparatus sends joins request message or in the adding response message, or by sending other other message indications.The distribution of services device can also receive user's Play Control operation requests by E2 interface indication sharing operation device, and sends shared Play Control operation requests to fixed shared Executive Module when receiving user's Play Control operation requests.
For the content viewing apparatus that does not possess the Play Control power of sharing the control group, the distribution of services device can uncertain this content viewing apparatus correspondence the sharing operation device, instruction content viewing apparatus shielding user's Play Control operation requests, or determine corresponding sharing operation device, but the Play Control operation requests that Executive Module is not carried out this sharing operation device is shared in indication.
In this step, under the control of Sharing Management module, share the Play Control relation between the Media Stream that Executive Module is set up and this content viewing apparatus is watched, so that, can carry out the Play Control operation of the Media Stream that this content viewing apparatus is watched receiving when sharing the Play Control operation requests.The execution of concrete Play Control operation, can be to share Executive Module to provide module to send the Play Control operation requests to the content of content viewing apparatus correspondence, or the Play Control operation requests sent to content viewing apparatus, carry out Play Control by content viewing apparatus, promptly provide module to send the Play Control operation requests by content viewing apparatus to content again.
Like this, after a plurality of content viewing apparatus add same group, in the distribution of services device, share Executive Module under the control of Sharing Management module, set up the play control proxy relation, promptly the control group should be shared in record which sharing operation device (which further can also write down have Play Control power), and which media content the Play Control action need affacts.When the shared Play Control operation requests that receives that the sharing operation device sends, affact these media contents, carry out sharing of Play Control.
This Media Stream is independently under the play control proxy mode, the media content that content viewing apparatus is watched can independently obtain from the IPTV business, distribution of services device and IPTV business may be in physical entities, or the part of distribution of services device for example Sharing Management module and IPTV business in a physical entity, set up in the IPTV media session process at content viewing apparatus, or by revising media session, the agent relation who sets up Play Control, but still the independence of maintenance media content.For example, in the content viewing apparatus adding group process or after adding the group, set up the sharing operation device and the Play Control passage between the shared Executive Module (being called the first Play Control passage) of content viewing apparatus correspondence by setting up new session, and the shared Executive Module content corresponding with content viewing apparatus of foundation provides the Play Control passage between the module (being called the second Play Control passage), set up the incidence relation between two control channels (i.e. first the and first Play Control passage), i.e. the agent relation.Or by revising session, provide the passage of the Play Control between the module with content viewing apparatus and the content set up, be revised as shared Executive Module and content the Play Control passage between the module (i.e. the second Play Control passage) is provided, set up the sharing operation device and the Play Control passage between the shared Executive Module (i.e. the first Play Control passage) of content viewing apparatus correspondence, and set up its agent relation.
Two, Media Stream interrelational form
Play Control under this mode is shared, because the media content that each content viewing apparatus is watched, be to provide by the unification of distribution of services device, the specifically distribution that provides module to finish media content by the content in the distribution of services device, content viewing apparatus receive and play obtain provide the Media Stream of module distribution by content.Owing to have incidence relation between the Media Stream, for example, provide module on the basis of same content source, to duplicate distribution by content and (may pass through processing such as transcoding therebetween, for example be converted to another kind of audio/video coding mode from a kind of audio/video coding mode, or the image size changes etc., but the media content of watching itself is identical, can being called with this content source with reference to content source, correspondingly, its Media Stream that provides is called with reference to Media Stream), the play operation of each content viewing apparatus correspondence all affacts on this same content source, also just be equivalent to affact simultaneously on each Media Stream, see identical media content on each content viewing apparatus thereby be implemented in.Here, the media content that content viewing apparatus will watch the distribution of services device to provide need be set up media session with the distribution of services device, to set up Media Stream.This can be by revising existing session, or newly-built session is finished.Wherein, revising existing session is to have set up the session that media content is watched between content viewing apparatus and the distribution of services device, for example, the distribution of services device is located in the IPTV Business Entity, by revising the attribute of session, to revise the source of Media Stream, set up and share related between the control group Media Stream.Content viewing apparatus and distribution of services device carry out the negotiation of Media Stream parameter as required again.Setting up new session is to set up the session that new media content is watched between content viewing apparatus and the distribution of services device, make content viewing apparatus receive and play from the distribution of distribution of services device with share the corresponding specific media content of control group.
No matter be by revising session or newly-built session, all be will set up session and share the related of control group, might as well be called to add and share the control group session.Content viewing apparatus is shared in the control group process in adding, or adds after the shared control group, adds to share and controls group session.Content viewing apparatus adds shared control group session dual mode:
(1) content viewing apparatus joins request to distribution of services device initiation control group session.
The distribution of services device receives group that group manage apparatus sends by the E1 interface and joins request after the message, send group's message that joins request by the E3 interface to content viewing apparatus, content viewing apparatus receives the group by the E3 interface and joins request after the message, sends the control group session message that joins request by the E3 interface to the distribution of services device; Or content viewing apparatus sends group's message that joins request by the E3 interface to the distribution of services device, receives after group that the distribution of services device sends adds response message, and content viewing apparatus sends the control group session message that joins request to the distribution of services device; Or content viewing apparatus directly sends the control group session message that joins request by the E3 interface to the distribution of services device, and this control group session joins request message simultaneously for group joining request message.
After distribution of services device processing controls group session joins request, send the control group session and add response message, thereby realize that content viewing apparatus adds the control group session, sets up the incidence relation of Media Stream.
The control group session joins request and can be arranged in the group and add response message, promptly controls group session and joins request that to add response message be same message for message and group; The control group session joins request and also can be arranged in group's message that joins request, and promptly controlling group session message and the group message that joins request that joins request is same message.
(2) the distribution of services device joins request to content viewing apparatus initiation control group session.
The distribution of services device receives group that group manage apparatus sends by the E1 interface and joins request after the message, initiating the control group session to content viewing apparatus joins request, at this moment, the control group session joins request and can be located in the group that the distribution of services device is sent to content viewing apparatus and join request in the message, promptly the group that sends to content viewing apparatus of distribution of services device to join request and control that group session joins request be same message; Perhaps the distribution of services device receives control group from group manage apparatus by the E1 interface and joins request after the message, send the group by the E3 interface and join request message to content viewing apparatus, after receiving that content viewing apparatus passes through group's adding response message of E3 interface transmission, the distribution of services device is initiated the control group session by the E3 interface to content viewing apparatus again and is joined request; Perhaps the distribution of services device joins request after the message by the group that the E3 interface receives content viewing apparatus, sends the control group session message that joins request to content viewing apparatus.
Under this dual mode, the group who transmits on the E3 interface joins request the content of the message that group joins request transmitted on message and the E1 interface can be inconsistent, for example, the distribution of services device is converted to direct media content information with the shared control group information of transmitting on the E1 interface by indirect media content information, for example will be with the media content of certain content viewing apparatus as reference, be converted to corresponding media content sign, for another example, the group who transmits on the E3 interface is joined request added information of distribution of services device or the like in the message.
Above-mentioned, the control group session message that joins request can be the SIP INVITE, or SIP REINVITE message etc.Can carry in the message and share the control group identification, sharing the control group identification can carry in the request resource locator Request of sip message URI, or request resource locator Request URI is still according to the existing mode of IPTV program, carry in addition in the message and share the control group identification, for example in header field or in the message body, carry.
After content viewing apparatus adds the control group session,, specifically provide module to send media content by the content in the distribution of services device by the media content of M1 interface reception from the distribution of services device.Content provides module to comprise clean culture and multicast to the mode that content viewing apparatus sends media content.
The media content that content provides module to provide may provide module itself from content, and for example module is provided is IPTV service media server to content, has stored media content or has obtained media content; Perhaps from other content source, need obtain in addition, for example come from the IPTV program content source, content provides the module need be by setting up IPTV program acquisition media content.For latter event, content provides the Media Stream between the other foundation of module needs and other content source, this can be to finish when shared control group sets up, be that the distribution of services device receives the group that group manage apparatus sends and sets up request message, carried group's content source information in this message, programme content sign for example, distribution of services device are set up the relation with the Media Stream of this content source etc. in the process of setting up the group, with the input of this Media Stream as group's media content.The distribution of services device also can be set up this Media Stream when first content viewing apparatus adds the group and add the control group session.
Add in the process of sharing the control group session at content viewing apparatus, for the content viewing apparatus that Play Control power is arranged, except by setting up new session or revising existing session to set up Media Stream or to revise existing Media Stream, set up outside the association of Media Stream, also will determine the sharing operation device corresponding with this content viewing apparatus, set up the Play Control passage between sharing operation device and the distribution of services device, be specially and the shared Executive Module of distribution of services device between set up the Play Control passage, and set up this Play Control passage and the incidence relation of group between the content source, make the Play Control operation will affact on the content source of sharing the control group.The content viewing apparatus that does not have Play Control power, the sharing operation device of uncertain correspondence, or also can determine corresponding sharing operation device, but share the Play Control operation requests that Executive Module is not handled this sharing operation device.
Like this, the Media Stream that adds the content viewing apparatus reception of sharing the control group session, come from the distribution of services device and on same content source basis, duplicate distribution (may pass through processing such as transcoding), the Play Control operation also affacts on this identical content source, and it is identical that the media content that these content viewing apparatus are watched keeps.
In the Media Stream interrelational form, the relation according between distribution of services device and the IPTV business (for example LTV business, VoD business) can be further divided into dual mode; The professional enhancing mode of the mode of Media Stream agency and play control proxy and IPTV.
(1) mode of Media Stream agency and play control proxy
Distribution of services device and IPTV are professional independent, and the distribution of services device obtains media content from the IPTV business, duplicate distribution to content viewing apparatus, when the distribution of services device receives the Play Control operation requests of sharing operation device of the content viewing apparatus correspondence with Play Control power, further carry out the Play Control operation to the IPTV service request.
(2) the professional enhancing mode of IPTV
The distribution of services device (for example is arranged in the IPTV Business Entity, in the LTV Business Entity, in the VoD Business Entity), be the enhancing of existing IPTV business, the i.e. association between the session of foundation adding group's content viewing apparatus in the IPTV business, and the association between the Media Stream and between the Play Control.
Step 103: the sharing operation device initiates to share the Play Control request to the distribution of services device.
Add the group at content viewing apparatus, and after carrying out the preparation of sharing Play Control, when the user with content viewing apparatus of Play Control power asked to carry out the Play Control operation, the sharing operation device corresponding with this content viewing apparatus sends to the distribution of services device by the E2 interface shared the Play Control operation requests.
Description according to the front, among the present invention, shared Play Control has several different implementations, is respectively Media Stream independent play-out control ways of distribution, Media Stream independent play-out control agent mode, Media Stream agency and play control proxy mode, the professional enhancing mode of the related IPTV of Media Stream.Wherein, first kind of mode is a kind of passive mode, and the back is a mode initiatively for 3 kinds.
1) under passive mode, when the sharing operation device corresponding with content viewing apparatus detects the media content generation Play Control operation that this content viewing apparatus (promptly have Play Control power content viewing apparatus) watches, trigger sharing of Play Control, send to the distribution of services device and share the Play Control operation requests.
Under this mode, the media content that adding group's content viewing apparatus is watched is independently to obtain from the IPTV business, content viewing apparatus with Play Control power also can process user the Play Control operation requests, carry out the Play Control operation (content viewing apparatus that does not possess Play Control power, shielding user's Play Control operation requests under the indication of distribution of services device) of the media content of oneself watching to the IPTV service request.The sharing operation device need detect the generation of Play Control of the user request of content viewing apparatus, this can be to receive the also Play Control operation requests of process user at content viewing apparatus, or content viewing apparatus sends user's Play Control operation requests, or content viewing apparatus receives the response of IPTV business to user's Play Control operation, or the IPTV business receives the Play Control operation requests of user's request, or the professional Play Control operation of carrying out user's request of IPTV, or the IPTV business finishes the execution of the Play Control operation of user request, etc. the Play Control operation of the user's request that detects content viewing apparatus under the situation.
The another kind of situation of the media content generation Play Control operation that content viewing apparatus is watched is because other content viewing apparatus request Play Control operation is arranged, because Play Control is shared the media content that causes this content viewing apparatus self to be watched same Play Control operation takes place also.This because of sharing the Play Control operation that causes, should not trigger sharing of Play Control again.Therefore, if the sharing operation device can detect this Play Control operation, need this Play Control operation of identification whether to share and cause, if, so no longer trigger sharing of Play Control, promptly do not send and share the Play Control operation requests to the distribution of services device.Otherwise, trigger sharing of Play Control.Perhaps, be set to the sharing operation device according to system's needs and can only detect the Play Control operation that content viewing apparatus is initiatively initiated, and can't detect for share the Play Control operation that causes because of Play Control.
Wherein, the Play Control of the media content of watching at sharing operation device identification content viewing apparatus operates whether Play Control is shared when causing, can realize in the following manner: the source of identification Play Control operation requests, for example the Play Control operation requests is a Client-initiated, and still shared Executive Module is initiated; Or the indication by carrying in the Play Control operation requests, the reason of for example indicating Play Control to operate is that the user operates, and still is to cause because share.
2) under active mode, the user's of content viewing apparatus Play Control operation requests is received and is handled by the sharing operation device of correspondence, or content viewing apparatus sends to corresponding sharing operation device after receiving user's Play Control operation requests, sent to the distribution of services device by the sharing operation device and shares the Play Control operation requests.
Wherein, sharing Play Control operation requests message can be RTSP PLAY/PAUSE message, IGMP leave/join message, SIP REINVITE message, HTTP request message etc.
Step 104: the shared Play Control operation requests that the distribution of services device receives and processing sharing operation device sends, what the Play Control in the execution group was operated shares.
In this step, the distribution of services device receives the shared Play Control operation requests that the sharing operation device sends by the E2 interface, the distribution of services device is handled and should be shared the Play Control operation requests, for example authentication is carried out in the Play Control request, judge whether corresponding content viewing apparatus has Play Control power, and authentication is carried out the Play Control operation by the back.Wherein, this Play Control is operated to rare following 3 types:
1, change the platform operation, switching channels when promptly watching programme televised live.
2, switch between the time shift/live, when promptly watching the programme televised live of supporting time-shift service, enter watching of time shift content from live, or from the time move up into watching of live content.
3, VCR operation, i.e. operations such as time-out, F.F., rewind down, recovery broadcast.Shifting state when programme televised live, or all can carry out the VCR operation in program request (for example VoD) the program viewing process.
At previously described four kinds of Play Control sharing modes, discuss the implementation that this Play Control of explanation is shared below respectively:
1) Media Stream independent play-out control ways of distribution.
The Sharing Management module is determined the shared Executive Module of content viewing apparatus correspondence according to the content viewing apparatus that adds the group.After the distribution of services device receives the shared Play Control operation requests of sharing operation device, specifically be to receive this shared Play Control operation requests by the Sharing Management module in the distribution of services device, according to the corresponding relation between content viewing apparatus and the shared operating means, identify the content viewing apparatus of the sharing operation device correspondence that sends this shared Play Control operation requests, Play Control is operated the corresponding shared Executive Module of other guide viewing apparatus that is distributed to this group of adding outside the shared Executive Module corresponding with this content viewing apparatus, carry out the Play Control operation respectively by these shared Executive Modules.Like this, the media content watched of other content viewing apparatus has been carried out same Play Control operation.
Shared Executive Module is specifically carried out the mode of Play Control operation, can be that the Play Control operation requests is sent to content viewing apparatus, finishes the Play Control operation by content viewing apparatus.Also can be the Play Control operation to be directly acted on to content viewing apparatus provide the content of media content that module is provided, promptly the content to correspondence provides module to send the Play Control operation requests.
2) Media Stream independent play-out control agent mode.
Under this mode, owing to set up the play control proxy relation of sharing operation device and shared Executive Module, promptly this group has which sharing operation device (which further can also write down have Play Control power), and which media content the Play Control action need affacts.The distribution of services device receives shares the Play Control operation requests, be specially by distribution of services and put the shared Play Control operation requests that interior shared Executive Module receives the sharing operation device, and the Play Control of all each self-corresponding media contents of content viewing apparatus of execution adding group is operated.
