Described media player comprises equipment information management module, Control Server module, event server module, state table administration module and other service modules, as shown in Figure 2.Wherein, the equipment information management module is used for the facility information of management of media player, comprises the description document of obtaining player device at any time, the information of preserving and update the equipment; The Control Server module is used for receiving and resolving control point service invocation request message, sends the service call response message to the control point; The event server module is used for receiving and resolving control point Service events subscription request message, sends the response message of Service events subscription and issues Service events to the control point; The state table administration module is used for management of media player status variable information, comprises renewal, interpolation and the deletion etc. of state variable.Other service modules comprise IGRS underlying protocol stack and XML data resolution module, wherein, the IGRS underlying protocol stack is provided by each producer, the mutual discovery mechanism pipes between devices of the equipment that defined set-up mechanism, service discovery mechanisms, session management mechanism and service access mechanism are for the control point provides perfect IGRS network communication interface; And described XML data resolution module is used to provide the parsing interface of XML format information.
Below Control Server module and event server module are made a concrete analysis of.
1. the concrete analysis of Control Server module is as follows:
Player is resolved the service invocation request message at control point, obtain the title of the interface of service call, check whether player supports this service, if do not support then to send the error message of service call to the control point, if support then to carry out concrete service, then send the service call error message if service execution is unsuccessful, if the service execution success then sends the result of service call to the control point, as shown in Figure 3 to the control point.
Control Server module concrete function be the management of media server with player between be connected, control media delivery and broadcast, control media play present characteristic etc., the key data structure of this module is analyzed as follows (other are with reference to IGRS AV application framework document):
The link information data structure, this structure memory allocation is given the connection Id at control point and the link information of this Id correspondence, as transmission control protocol, current connection status etc.;
AV transmit information data structure, this structure memory allocation are given the AV transmission Id at control point and the transmission information of this Id correspondence, as current transmission state, transmission speed, media information etc.;
RCS information data structure, this structure memory allocation are given the presentation information that presents control service Id and this Id correspondence at control point, as the volume play, brightness etc.
Above-mentioned three structures can be integrated into a structure, because one connects unique corresponding one group and connects Id, AV transmission Id and present control service Id.
Described Control Server module specifically comprises following three part main functional modules:
(1) connection management module, the implementation method of this module is:
Player is resolved the request of connecting at control point, obtain the condition of input, if condition does not conform to rule and sends error message to the control point, then distribute the free time to connect Id if condition is legal, if initialization link information structure is server support media source transmission service (AVTS), then distribute idle AV transmission Id, initialization " AV transmits message structure ", the connection Id from distribution to the control point and the AV that return transmit Id, as shown in Figure 7.
Player link information query requests is handled the link information query requests of at first being resolved the control point by player, obtain the condition of input, if condition does not conform to rule and sends error message to the control point, if condition is legal then according to the connection Id inquiry link information structure of importing, obtain corresponding link information and send to the control point, as shown in Figure 6.
(2) AV transport management module, the implementation method of this module is:
Resolve the media delivery request at control point, obtain the condition of input, if the condition of input is illegal, then send error message to the control point, if condition is legal, then obtain corresponding link information and the server transmission data that connect according to the AV transmission Id of input, and to control point transmission object information, as shown in Figure 8.
Resolve control point transmission information inquiring request, obtain initial conditions, if initial conditions is illegal, then send error message to the control point, if condition is legal, then the AV transmission Id according to input inquires about AV transmission message structure, obtain corresponding link information and send to the control point, as shown in Figure 9.
(3) RCS administration module, the implementation method of this module is:
Resolve to play and present control request, obtain initial conditions, if initial conditions does not conform to rule and sends error message to the control point, if the legal controlled function that presents that then starts player of condition according to the condition of input, carry out concrete operations (as volume, pattern etc. are set), as shown in figure 10.
Resolve the control point and present the control information query requests, obtain initial conditions, if condition does not conform to rule and sends error message to the control point, then present control information on services structure if initial conditions is legal according to the control service Id inquiry of importing that presents, obtain corresponding link information and send to the control point, as shown in figure 11.
2. the concrete analysis of event server module is as follows:
(1) main data structure is analyzed, other are with reference to IGRS AV application framework document.
The subscription information structure, the relevant information that this structure storage control point CP subscribes to the media player Service events, all subscription information structures are formed player end service subscription information table.
(2) main functional modules is the subscription information administration module, and the implementation method of this module is:
The analysis service event subscription requests, this subscription information is then deleted in request from the service subscription information table if cancel subscriptions, if not the request of cancelling subscriptions, then distribute idle service ID, initialization " subscription information structure ", upgrade the subscription information table, return service ID and other subscription information to the control point, as shown in Figure 4.
State variable changes, and has events subscribed to take place, and inquiry service subscription information table is not if existence for the subscription of this incident, then to corresponding subscription control point issuing service incident, as if the subscription that does not exist this incident, is then done any operation, as shown in Figure 5.
As mentioned above, the present invention can realize the AV player end based on the IGRS agreement, uses method of the present invention can develop IGRS AV player 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.
