Embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
IGRS AV control point equipment proposed by the invention comprises media server, control point and media player, and concrete syndeton is referring to shown in Figure 1.Described media server provides control directory services, the service of source of media connection management, source of media transmission service, and these services provide calling interface to the control point; Described media player provides the service of target connection management, presents control service and media object transmission service, and these services provide calling interface to the control point; Described control point is by finding media services, and the interface that the service of calling provides is controlled media server and media player, media delivery and broadcast between finishing from the media server to the media player.
5 aspects such as the concrete function at IGRS AV control point can the slave unit discovery, description, control, event handling, monitoring of tools are set forth, and are specific as follows:
1. the IGRS AV equipment in the discovery network comprises media server, media player, as shown in Figure 2.
2. retrieve the device descriptive information of the IGRS AV equipment of finding, the service list that the equipment of obtaining provides.By the service list of equipment, search interested service and obtain service description information, as shown in Figure 3.
3. transmit control message to equipment, carry out service call, inquiry service current state or control media play, as shown in Figure 4.
4. be scheduled to the device service event source, change the state variable value of respective service according to event source, as shown in Figure 5.
5. check the state and the unit exception processing of equipment at any time.
Based on the function at IGRS AV control point, IGRS AV control point can be made up of following 5 primary modules, makes a concrete analysis of below.
The IGRS underlying protocol stack is provided by each producer, the mutual discovery mechanism of the equipment that defined, pipes between devices set-up mechanism, service discovery mechanisms, session management mechanism and service access mechanism, and major function is to provide perfect IGRS network communication interface for the control point.
The XML data resolution module, various requests of regulation and notification message all are that the XML form transmits in the IGRS agreement, this module provides the parsing interface for the XML data.
The equipment information management module, mainly be to realize to the definition of IGRS AV facility information type structure and the management of facility information, wherein, type structure comprises IGRS Device, IGRS Service, IGRSAction, IGRS Argument, IGRS StateVariable etc., and management function comprises the obtaining of equipment, increases, change, deletion, inquiry, printing etc.
The monitoring of tools functions of modules comprises device discovery, online, off-line event handling, facility information inquiry and unit exception processing etc., and it comprises following three submodules:
1. device discovery and facility information query processing module are used for the transmitting apparatus search request, and treatment facility is searched response events and the online declaration incident of equipment (with reference to figure 2,3).Receiving equipment is searched response events or the notification event of reaching the standard grade, call " XML data resolution module " interface, the data that receive are resolved, according to equipment I d, call " equipment information management module " interface, the checkout facility tabulation, if this equipment exists, change the time spot of this facility information, otherwise resolution data again, obtain device descriptive information (download or directly in data, obtain) according to URL, the analyzing device descriptor obtains the equipment essential information, if there is service in equipment, then obtain service description information (download or directly in data, obtain) according to URL, according to " equipment information management module " interface, apparatus for establishing information is updated the equipment and is served list information, if do not have the service information of then only updating the equipment, as shown in Figure 6.
2. equipment off-line event processing module, after the message that is used for when an IGRS equipment that the control point receives network withdraws from, being sent, if this equipment is not present in the list of devices, then be left intact, if be present in the list of devices, then to judge whether to have subscribed to the service of this equipment, if there is not subscription service then directly this equipment to be deleted from the list of devices at control point, if subscribed to service, need to send earlier the message that cancels subscriptions, the service that deletion is relevant is also deleted this equipment simultaneously from the list of devices at control point, as shown in Figure 7.
3. whether unit exception processing module is used for checkout facility and is not sending under the situation of deferred information unusual off-line or checking the equipment presence that does not send announcement message in the online declaration incident of regulation, and list of devices is carried out respective handling.
(two modular structures are similar with player control point protocol stack module for media server, be combined into a module at this), this functions of modules comprises the control point initialization, calls the service interface of media server and media player, to media server and media player control, Service events subscription etc., be the nucleus module at control point, it is made up of three submodules:
1. media server and media player control point initialization module, be used for the initialization server and needed environment and variable are moved in the media player control point, start and close media server and media player control point, for the discovery of equipment, control etc. are prepared.
2. device control module is used for discovering device, obtain the descriptor of equipment and service after, the control point just can be controlled equipment.This functions of modules comprises to target device transmission Soap form service invocation request message, comprises operation requests and service variable query message, handles service call response events (with reference to figure 4).When equipment has been finished the control point service call, send return results message to the control point, after the control point receives message, data are resolved, if the result who returns is wrong, then carry out fault processing,, judge whether this equipment is present in the list of devices if the result who returns is correct, if exist, then change equipment corresponding apparatus information, be not left intact if do not exist then, as shown in Figure 8.
3. Service events is subscribed to processing module, is used for sending to target device that Service events is subscribed to, the message of subscribing to again, cancel subscriptions, handle subscribe to, subscription response incident, Service events are handled (with reference to figure 5) and subscription timeout treatment etc. again.
Service events is handled, and the analysis service subscribe message obtains service subscription ID, if do not have this equipment in the list of devices, then be left intact, if exist this equipment then to obtain this facility information and subscription service information, and the information on services of updating the equipment, as shown in Figure 9.
Subscribe to timeout treatment, resolve and subscribe to the result that time exceeded message returns, if do not have the service devices needed in the list of devices, then be left intact, as if there being then subscription service again, then cancel subscriptions if subscribe to get nowhere, delete this equipment, if subscribe to again and successfully then obtain subscription service ID change information on services, as shown in figure 10.
As mentioned above, the present invention can realize the AV control point based on the IGRS agreement, uses method of the present invention can develop IGRS AV control point fast and effectively.Certainly; above-mentioned explanation is not to be limitation of the present invention; the present invention also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also should belong to protection scope of the present invention.
