Figure 10 represents that blog reservation file according to an embodiment of the invention uses the process flow diagram of processing 1000.Blog is subscribed file and is used and handle 1000 and for example carried out by client computer (for example, operate on the client devices media management application).

Blog is subscribed file and is used the processing 1000 initial 1002 portable blogs that obtain to subscribe file (PPSF).Before blog is subscribed other processing of file use processing execution, can obtain 1002 portable blogs and subscribe files.Just, judge that 1004 determine whether to make the request for opening portable blog reservation file.For example, but open the request signal and transmit the OpenURL incident.When judging that 1004 determine not make when opening portable blog and subscribe the request of file, blog is subscribed file and is used and handle 1000 and only wait for such request.

In case judge that 1004 determine to have made the request for opening portable blog reservation file, judge that then 1006 determine whether media management application (MMA) are moved.Generally speaking, media management application will be moved on client devices.When the present off-duty of media management application is determined in judgement 1006, then start 1008 media management application.After square frame 1008, maybe when moving, definite media management application judging after 1006, resolve 1010 portable blogs and subscribe file, to get access to the URL that presents of the blog that is associated at least.In one embodiment, can be URL scheme (" itpc " or " pcast ") for the request of opening portable blog reservation file, it is identified as the XML document that will resolve and be used to subscribe blog by media management application.

Next, blog is subscribed file and is used and handle 1000 and subscribe 1012 blogs that are associated.Under the condition that does not have from the user's of media management application any feedback or input, can automatically perform the reservation 1012 of the blog that is associated.Yet,, can carry out additional treatments to show whether they will subscribe blog about the descriptive information of blog and/or inquiry user if need.In other words, the user can confirm the additional information that they want to subscribe relevant blog and/or user and can receive the blog that will subscribe about them (for example, title, describe explanation etc.).In any case, after square frame 1012, blog is subscribed file and is used processing 1000 to finish.

Figure 11 represents blog reservation system 1100 according to an embodiment of the invention.Blog reservation system 1100 comprises client devices A 1102, client devices B 1104 and blog trusteeship service device 1106, its each all be operably connected with data network 1008.Client devices A 1102 comprises media management application (MMA) 1110, and client devices B 1104 comprises media management application (MMA) 1112.Client devices A 1102 creates or obtains portable blog and subscribes file 1114.Portable blog can be subscribed file 1114 and be transferred to one or more other client devices.In this example, can suppose that portable blog reservation file 1114 is by media management application 1110 establishments.

Subscribe file in case media management application 1110 has portable blog, media management application 1110 just can be subscribed file 1114 by the portable blog of data network 1108 transmission.In this example, suppose portable blog to be subscribed this media management application 1112 that file 1114 is transferred to client devices B 1104 by data network 1108.Therefore, as shown in figure 11, show portable blog reservation file 1114 in the frame of broken lines in client devices B 1104.

Afterwards, the media management application 1112 of client devices B 1104 can be used portable blog to subscribe file 1114 and subscribe relevant blog.More particularly, subscribe file 1114 if the user of client devices B 1104 will " open " portable blog, as by the double-click behavior, then media management application 1112 will " be opened " request of Request Processing one-tenth to media management application 1112 reservation blogs.In this example, blog is on the blog trusteeship service device 1106.Particularly, portable blog is subscribed file 1114 and will be resolved by media management application 1112, to obtain the URL that presents about the podcast feeds 1116 that is in the blog on the blog trusteeship service device 1106.Media management application 1112 can be visited podcast feeds 1116 then, thereby to obtain and to store specific blog information at client devices B 1104 places.

Should be appreciated that, generally speaking, can adopt multitude of different ways that portable blog is subscribed file (for example, portable blog is subscribed file 1114) and be transferred to one or more other client devices.For example, can portable blog be subscribed file by email message and send to the user who is associated with client devices.Then, the user can open portable blog and subscribe file to activate the reservation to blog.In another example, portable blog can be subscribed linking on file and the webpage is associated.Thereby, when the user on the website selects link that webpage is associated, can handle to be used for subscribing blog by media management application afterwards with portable blog subscribed for file download to the client devices that is associated with the user.In another example, can pass through portable computer-readable media,, transmit portable blog and subscribe file as flash card on the floppy disk or CD.

Another aspect of the present invention is subscribed about removing (deactivate) blog.More particularly, this aspect of the present invention is used for removing and is considered to and sluggish reservation.In one embodiment, removing processing can automatically perform.Releasing is considered to and an advantage of sluggish reservation is, but conserve network bandwidth.Releasing is considered to and another advantage of sluggish reservation can be, and the trusteeship service device of trustship blog can not be subjected to blog seldom or the download request of the user's that loses interest in client application and the burden that causes.

Figure 12 represents that blog according to an embodiment of the invention upgrades the process flow diagram of processing 1200.Blog upgrade to be handled 1200 and is for example carried out by client computer (as, media management application).

Blog upgrades processing 1200 and starts from judging 1202, and it determines whether to carry out blog and upgrades.When judgement 1202 determined not carry out the blog renewal, then blog upgraded and handles 1200 waits, till carrying out the blog renewal.In other words, in the time will carrying out the blog renewal, effectively call blog and upgrade processing 1200.Can ask blog to upgrade by client computer or client user.For example, client computer may start the blog renewal termly automatically.

On the other hand, when judgement 1202 determines to carry out the blog renewal, then visit the podcast feeds (for example, RSS presents) of 1204 specific blogs, to obtain the frag info of this blog.Then, based on the frag info that obtains, judge the new segment of 1206 blogs.In one embodiment, the frag info that obtains is the XML file that comprises the metadata of the characteristic of describing specific blog, and this specific blog comprises each fragment of blog.Can resolve the XML file, to obtain frag info (for example, fragment metadata).Inspection to frag info can be used for identifying, with on the time more early or previous available those fragments blog new segment comparatively speaking at the client computer place.

Next, judge that 1208 determine whether the blog new segment that will download.Herein, new segment can obtain from the trusteeship service device of this blog, thereby it can be downloaded to client computer.When judgement 1208 defined the new segment that will download, blog upgrades handled whether 1200 judgements, 1210 blogs are sluggish.When judging that 1212 definite blogs enliven, then new segment is downloaded 1214 to client computer.New segment is downloaded after 1214, received blog with client computer and more newly arrived and finish and finish blog and upgrade and handle 1200.On the other hand, when judge 1208 determine will not download new segment the time, maybe when judging 1212 when determining that blogs are inactive, then under the condition of not downloading any new segment, finish and finish blog and upgrade processing 1200.

Figure 13 represents active 1300 the process flow diagram of handling of blog according to an embodiment of the invention.The active processing 1300 of blog is generally used for determining that blog enlivens or sluggish.For example, according to one embodiment of present invention, can handle 1300 and be used as the processing that realizes by as shown in figure 12 judgement 1210 blog is active.In this embodiment, for each (having subscribed) blog, all maintain at least one pair of variable and be used to judge that blog enlivens or sluggish.In this exemplary embodiment, variable is that fragment is downloaded counting and initial fragment download date.

The active processing 1300 of blog starts from judging 1302, and it determines that whether blog download counting is greater than Integer N.When judging that 1302 definite fragments are downloaded counting greater than N, judge 1304 determine whether surpassed M days from the date of initial fragment download, wherein, M is an integer.For example, integer M and N can equal 5.When judging that 1304 determine to have surpassed M days from the date that initial fragment is downloaded, judge that then 1306 determine whether the date client computer of downloading from initial fragment is active.When judging that 1306 determine to enliven from the date client computer that initial fragment is downloaded, then that 1308 one-tenth of blog draftings is inactive.Herein, active not enough owing to the active processing 1300 of blog is determined blog with programming mode in this embodiment, thus 1308 one-tenth of blog draftings is inactive.Therefore, suppose that client user seldom or not interested in the blog.Thereby, will upgrade the download 1214 of handling 1200 new segment of carrying out by blog as shown in figure 12 and skip, thereby save network and server resource.

On the other hand, when judging that 1302 definite fragments download countings are no more than N, maybe, perhaps work as and judge that 1306 determine that the date client computer of downloading from initial fragment is just inactive, then blog is drawn 1310 one-tenth and enliven when judging that 1304 determine when the date that initial fragment is downloaded surpasses M days.After square frame 1308 and 1310, finish and finish that blog is active handles 1300.

Figure 14 represents the process flow diagram of replacement active variables processing 1400 according to an embodiment of the invention.The replacement active variables is handled 1400 and is for example carried out by the client computer that operates on the client devices.Client computer is used in its operating period active variables of resetting between when appropriate, so that handle 1300 generation effects to above with reference to the described blog of Figure 13 is active.In other words, at special time, the active 1300 employed active variables of handling of the blog of can resetting are so that exert an influence to the operation of the active processing 1300 of blog.For example, the active variables of resetting can comprise the date that fragment download counting or initial fragment are downloaded.Notice that these replacement variablees can be directly exert an influence to the judgement 1302,1304 and 1306 of the active processing 1300 of blog.

The replacement active variables is handled 1400 and is started from judging 1402, and it determines whether to have set up the replacement condition.The replacement condition can adopt multitude of different ways to set up.Replacement condition automatically starting or start by the user.In any case, when judgement 1402 was determined not have the replacement condition, the active variables of then resetting was handled 1400 and is waited for such condition.In other words, replacement active variables is handled 1400 and is started from when satisfying in the suitable replacement condition.In case judge that 1402 determine to satisfy suitable replacement condition, 1404 fragments of then resetting are downloaded counting.Fragment can be downloaded counting replacement 1404 herein, is zero.In addition, the date that initial fragment is downloaded resets 1406.Herein, can be current date with the date replacement 1404 of initial fragment.After square frame 1406, finish and the active variables processing 1400 that finishes to reset.
