E.DLNA, which throws screen and handles this using the query result based on step D and throw, shields request, and processing throws screen and requests specific packetIt includes receiving and throws screen or refusal throwing screen, and throw screen end return processing result to mobile.

DLNA throws the method for screen authority managing and controlling, it can be achieved that in Android intelligence in Android intelligent television through the inventionCan television reception to push throw screen request when, first distinguish the equipment whether the credible equipment of known identities, only the TV ownerThe equipment of approval is just allowed to throw screen, otherwise requests the throwing screen for not receiving unidentified equipment, by the permission for throwing screen requestControl authorizes throwing screen of the credible equipment in Android intelligent television, prevents the throwing screen of unknown device from occurring, thus effectivelyIt ensure that DLNA throws the safe handling shielded in Android intelligent television.

Currently, Android intelligent television as the receiving device shielded is thrown, is only to identify throwing screen resource on old process,It is played in the machine.In order to realize that throwing screen equipment permission is controlled, need to throw screen process in originally requested content in this programmeMiddle increase rights management node, for screen equipment is thrown come classification processing, providing authorisation device, to throw screen operation, authorised device automaticThrow the processing strategies such as the throwing screen of screen, refusal unauthorized device.

In the present embodiment, it in order to implement this programme in the Android intelligent television of the present embodiment, is also based onThe throwing screen Authority Design of facility information, the original DLNA device of the Android intelligent television of the present embodiment throws screen process canSummary are as follows: when mobile end equipment is initiated to throw screen operation to Android intelligent television, send throw the ground that screen request carries resource firstLocation is to television；Television application parses information after receiving throwing screen request, obtains media money according to address by player layerSource plays and shows in the machine.

In order to realize the control for throwing screen equipment permission, request to design in responding process in above-mentioned throwing screen in the present embodimentOne independent authority management module, after supporting player layer to receive throwing screen request message, for the throwing of device flag settingThe rights management node whether screen operation is allowed to.The throwing screen authority management module provides the static interface of inquiry and modification, mentionsPlayer layer is supplied to call.The unique identification by equipment is only needed when throwing screen rights interface and calling, it can be by simpleStatic method shields permission to judge or modify throwing.It, can be in addition, based on " throw screen authorization " item is newly increased in complete machine setting applicationFacilitate enabling to throw screen equipment authorization function, the processing for throwing screen authorization can also be removed in safe WIFI environment.

Specifically, throw the method for screen authority managing and controlling for DLNA in the Android intelligent television of the present embodiment as shown in Figure 1The schematic diagram for realizing framework has specifically included the DLNA agreement thrown in screen end equipment and Android intelligent television in the architectureStack processing module, Android player throw screen equipment authority management module, throw screen authorization switch, wherein at DLNA protocol stackIt manages module, Android player, throw screen equipment authority management module in DLNA throws and shields.

Wherein, throwing screen equipment authority management module is the starting provided in setting application for compatible subscribers use habitThe switch of screen permission is thrown, specifically, mobile end equipment DLNA can be directed to when throwing screen when throwing screen priority assignation is " opening " stateThe equipment does throwing screen permission processing (the monitoring process in this method can be embodied), and throwing screen permission when setting is " closing " shapeState then executes original throwing screen process flow, does not do authority managing and controlling.

Specifically, the DLNA protocol stack such as following table institute that DLNA throws screen is handled in the present embodiment in Android intelligent televisionShow:

Layered protocol	Description
		Android player	Android broadcast layer
UPnP protocol	It encapsulates UPnP " action ".
		Http protocol	Obtain http data
TCP/IP	Socket transmission network data

According to UPnP protocol, there is no the pushing equipment end IP address relevant informations in http protocol in original realization.ForPush end equipment information is obtained, the realization of this layer protocol will be implemented to be transformed in the present embodiment, will be parsed in push requestThe IP address at pushing equipment end be encapsulated in UPnP " action " structure in certain field, pass to broadcast layer.Broadcast layer obtainsAfter the IP address for throwing screen equipment to current push, by the network routing address inquiry table of TV local record, push is gotThe MAC Address of equipment.For broadcast layer using MAC Address as the unique designation of equipment identities, subsequent throwing shields rights management for foundationMAC Address is realized.

Meanwhile it is also some to having been carried out in Android intelligent television end DLNA throwing screen application to protocol library in the present embodimentScalability modification, main thought are that the IP address information carried in screen request, the ground saved by the end TV are thrown using pushing equipmentLocation resolution table (ARP table), finds the MAC Address at pushing equipment end, carries out the identification of equipment throwing screen permission based on MAC Address and testsCard.

Television TV when receiving the push of other equipment is abstract as a DMR, runs a HttpServer thread prisonThe http packet for listening pushing equipment to send is assisted in http protocol layer calling SetupResponse function to UPnP after receiving push packetIt discusses layer transmission request and obtains and respond.

SetupResponse function prototype is as follows:

PLT_HttpServer::SetupResponse(NPT_HttpRequest&request,

const NPT_HttpRequestContext&context,

NPT_HttpResponse&response)；

UPnP protocol layer calls ProcessHttpPostRequest parsing http after receiving HTTP server push requestPacket, and the action packet that UPnP protocol defines is repacked according to HTTP content, pass to renderer layers of processing.In this mistakeBottom-up information in HttpRequestContext about ip will not be packed into account by the action packet realized originally in journey.AndThoroughly HttpRequestContext can be abandoned not when the PLT_MediaRenderer::OnAction () processing of next stepIt uploads again.

In this regard, we are when PLT_MediaRenderer::OnAction () is handled by PLT_Ip information in HttpRequestContext parses and is uploaded to CHMediaRenderDelegate::OnSetAVTransportURI () passes to Android player layer eventually by jni.

Improved ProcessHttpPostRequest, OnAction, OnSetAVTransportURI function prototype is such asUnder:

PLT_DeviceHost::ProcessHttpPostRequest(NPT_HttpRequest&request,

const NPT_HttpRequestContext&context,

NPT_HttpResponse&response)；

PLT_MediaRenderer::OnAction(PLT_ActionReference&action,

const PLT_HttpRequestContext&context)；

CHMediaRenderDelegate::OnSetAVTransportURI(PLT_ActionReference&action,

NPT_String&remoteIP)；

So far, DLNA protocol stack transformation finishes, and the IP address at pushing equipment end is output to player layer.

Meanwhile it is also specifically disclosed that a kind of player layer throws screen permission based on the equipment that MAC Address is realized in the present embodimentManagement, ARP, that is, address resolution protocol is the basic agreement of network transmission package, and each networked devices locally can learn and tie upProtect the machine ARP table, be stored in local file system using file mode, as in android smart television/proc/Net/arp file.Based on ARP information, the MAC Address of available corresponding IP as throws the MAC Address of screen equipment.Based on MACThe query interface of screen rights state is thrown in call by location, returns to the throwing screen of the throwing screen or refusal current device that receive current device.Throw all process steps in the step D for realizing logical process and this method inside screen authority management module.

When being embodied and using this method, when Android intelligent television implements factory reset operation, it will emptyThe throwing screen authority records of local record, including permanently authorize throwing screen, permanent refusal to throw screen, be rejected throwing screen but continuous refusalThe record list of the insufficient three classes equipment of number.When throwing screen permission grant switch state changes, screen authority management module is thrownIt is all revert to init state, empties all throwing screen authority records.

When local area network switches, since push section and receiving end when DLNA, which is thrown, to be shielded all must be in same local area networks, such asThe access network of fruit television switches, then moving the network at delivery end must also cut in new network.Local area network becomesWhen change, network ip address may change, but the device mac address of access network is will not to change, to based on MACThe throwing screen rights management of address does not influence, and throws screen authority records and remains unchanged.

It is understood that the principle that embodiment of above is intended to be merely illustrative of the present and the exemplary implementation that usesMode, however the present invention is not limited thereto.For those skilled in the art, essence of the invention is not being departed fromIn the case where mind and essence, various changes and modifications can be made therein, these variations and modifications are also considered as protection scope of the present invention.
