The embodiment of the present invention is applied in DLNA, and described DLNA includes: DMS, DMP, DMR and
DMC。
In described DMS, storage has media resource, described media resource to include content of multimedia and and multimedia
The caption content that content is corresponding；But, some media content, such as audio-video document are usually without captions
Content, now, using caption content corresponding for audio-video document as independent content, this content is the most plug-in
Caption content；When playing the audio-video document without caption content, playback equipment is in reading multimedia
While appearance, in addition it is also necessary to read plug-in caption content, so, just can make described content of multimedia with described outside
Hang caption content to synchronize to play, show the captions of its correspondence when playing audio-video.
In order to enable playback equipment conveniently to obtain plug-in caption content, newly-increased plug-in in existing item element
Title, so, it is achieved the purpose of content of multimedia broadcasting Tong Bu with described plug-in caption content, below
The process of implementing is described in further details.
In DLNA technical specification, the CDS in UPnP defines item element, wherein, described item unit
Element is used for representing multimedia document information, has given a definition each attribute at item element, for showing that these are many
The various characteristics of media file information；Wherein, described attribute includes but not limited to following: title, media divide
Class, protocol information, multimedia file URI；Here, described multimedia file URI is served only for representing many matchmakers
Body content file position, can not indicate the plug-in caption content place corresponding to multimedia file content
Position, therefore, shows the purpose of the plug-in captions of its correspondence, the present invention during for being capable of playing audio-video
Item element is extended by embodiment, to add plug-in title in the existing attribute of item element,
Described plug-in title is used for representing plug-in captions URI；
Such as, when the file that the plug-in caption content of only one of which is corresponding, outside described item element increases
Hang title can be expressed as:<subtitle>uRI</subtitle>；
When there being file corresponding to multiple plug-in caption content, the plug-in captions increased in described item element belong to
Property can be expressed as:<subtitle uri1＝”…”uri2＝”…”…/>；
So, each attribute of the described item element after extension can be to use the mode that is expressed as:
<item id=" 18 " parentID=" 13 " restricted=" 0 ">
<dc:title>Try a little tenderness</dc:title>
<upnp:class>object.item.audioItem.musicTrack</upnp:class>
< resprotocolInfo=" http-get:*:audio/mpeg:* "
Size=" 3558000 ">http: // 192.168.1.1/video197.mp4</res>
<subtitle url1=" http: // 192.168.1.1/video197.idx " url2=" http: // 192.
168.1.1/video197.sub”/>
<dc:title>Try a little tenderness</dc:title>
</item>
Here, the host-host protocol of described plug-in caption content is consistent with the host-host protocol of content of multimedia, permissible
Obtain from the protocolInfo of res, or other modes using DLNA agreement to provide obtain.
Figure 10 is the schematic flow sheet one implemented that the embodiment of the present invention plays the method for multimedia resource；
Described DLNA includes: when DMS, DMR and DMC, and as shown in Figure 10, described method includes:
Step 1001: described DMC obtains DMS by the Browse/Search action of the CDS of UPnP
The multimedia document information shared；Described shared multimedia document information includes multimedia file URI
With plug-in captions URI；
In the present embodiment, the step obtaining the multimedia document information that DMS shares includes:
Described DMC browses or searches DMS by the Browse/Search action of the CDS of UPnP and shares
Multimedia document information；
Described DMS generates response message based on Browse/Search action, and sends to described DMC.
In the present embodiment, described DMS is at the output parameter of the response message of response Browse/Search action
Multimedia document information is carried, i.e. with the multimedia document information of item element representation on Result；And,
Described item attribute of an element is expanded with plug-in title, wherein, outside described extension title includes
Hang captions URI；So so that described DMC can get multimedia file based on described response message
Information；Wherein, described multimedia document information includes multimedia file URI and plug-in captions URI；
Step 1002: described DMC gets multimedia to be played from shared multimedia document information
Fileinfo；Wherein, described multimedia document information to be played includes multimedia file URI with outer
Hang captions URI；
Step 1003: by the AVTransportURI action of AVT, described DMC informs that DMR waits to broadcast
The multimedia document information put；Wherein, described multimedia document information to be played includes multimedia file
URI, plug-in captions URI and other resource informations；
Wherein, input parameter AVTransportURIMetaData of AVTransportURI action comprises and needs
The multimedia document information play；Wherein, described multimedia document information to be played uses the item list of elements
Showing, described item attribute of an element is expanded with plug-in title, the most plug-in captions subtitle attribute；Also
That is, so the multimedia document information to be played of AVTransportURIMetaData parameter contains
Plug-in captions subtitle attribute；So so that described DMR can be played according in this input parameter
The plug-in captions subtitle attribute that comprised of multimedia document information know the address that plug-in captions are deposited, for
Described content of multimedia is laid a good foundation with the described Tong Bu broadcasting of plug-in caption content.
Step 1004: when described DMR receives after the play instruction of described DMC, described DMR
The plug-in caption content corresponding to multimedia document information to be played is obtained based on described plug-in captions URI；
Meanwhile, multimedia is obtained based on the multimedia file URI comprised in described multimedia document information to be played
Content, with the plug-in caption content that the display when playing content of multimedia is corresponding with described content of multimedia.
Figure 11 is the schematic flow sheet two implemented that the embodiment of the present invention plays the method for multimedia resource；
Described DLNA includes: during DMS and DMP, and as shown in figure 11, described method includes:
Step 1101: described DMP obtains DMS by the Browse/Search action of the CDS of UPnP
The multimedia document information shared；Described shared multimedia document information includes multimedia file URI
With plug-in captions URI；
In the present embodiment, the step obtaining the multimedia document information that DMS shares includes:
Described DMP browses or searches DMS by the Browse/Search action of the CDS of UPnP and shares
Multimedia document information；
Described DMS generates response message based on Browse/Search action, and sends to described DMC.
In the present embodiment, described DMS is at the output parameter of the response message of response Browse/Search action
Multimedia document information is carried, i.e. with the multimedia document information of item element representation on Result；And,
Described item attribute of an element is expanded with plug-in title, wherein, outside described extension title includes
Hang captions URI；So so that described DMP can get multimedia file based on described response message
Information；Wherein, described multimedia document information includes multimedia file URI and plug-in captions URI；
Step 1102: described DMP gets multimedia to be played from shared multimedia document information
Fileinfo；Wherein, described multimedia document information to be played includes multimedia file URI with outer
Hang captions URI；
Step 1103: when described DMP receives after the play instruction of user, and described DMP is based on described
Plug-in captions URI obtains the plug-in caption content corresponding to multimedia document information to be played；Meanwhile, base
The multimedia file URI comprised in described multimedia document information to be played obtains content of multimedia, with
The plug-in caption content that display is corresponding with described content of multimedia when playing content of multimedia.
Embodiment six
The embodiment of the present invention is applied in the 3-Box system of DLNA, and the device related to includes: DMC,
