[definition of term]

Term by the constituent element defining with reference to Fig. 8 in streptostyly content.

As shown in figure 8, scene (Scenario) is to exist with a time shaft and is normally in a streptostyly flowing The part held.Scene is made up of a content file and a VSI file, and this VSI file is the metadata literary composition of content file Part and describe VSI information wherein.The streptostyly content of Fig. 8 is by forming as follows：From a starting point to multiple end point In the range of 11 scene TS1 to TS5, LS1 to LS4, CS1 and CS2.

Mainly three types are categorized into according to the scene that the behavior at the end of scene is included within streptostyly content, i.e. Circulation scene, connection scene and termination scene.As shown in the circulation scene LS in Fig. 8, circulation scene refers to a certain from scene Regularly change and again return at the end of the reproduction of scene the scene of the transfer point of same scene.

In addition, as shown in the connection scene CS in Fig. 8, connecting scene is to be transformed at the end of the reproduction of scene and change The different scene in source or be transformed into different time position the scene of conversion source scene.

In addition, as shown in the termination scene TS in Fig. 8, terminating scene is to terminate streptostyly content at the end of scene reproduces Reproduction scene.

As above, scene represents the reproduction unit reproducing with single time shaft.

Event (Event) shows the time of scene and the regional area in space, and is transformed into another feelings with acting on The link of scape.It is the time location (time range) or locus (spatial dimension) specified in scene, and makes it possible to Enough conversions realized to another scene.In the streptostyly content of Fig. 8, in the range of a starting point to multiple end point It is assigned with multiple events in the centre of scene, and make to change to another scene from the situation of presence by event.

Bridge (Bridge) is the UI (user interface) in scene branch.In bridge, including about whether to another The operation that the user that scene is changed confirms, the selection in the case that chain is connected to multiple scenes etc. and whole picture Display specify.As shown in the part by the streptostyly content to Fig. 8 is amplified, when in terminating scene TS1 Between occur event when, to terminate scene TS5 bridge picture be shown, and if by user operation specify terminate scene TS5, then so that being transformed into termination scene TS5 from terminating scene TS1.

Branch (Branch) indicates the scene of the conversion destination with regard to related scene.In the streptostyly content of Fig. 8, example If scene TS2, TS3, TS4 and TS5 are the branch's scenes from the point of view of scene TS1.In addition, LS1, CS1 and LS2 are from TS2 From the point of view of branch's scene, TS2 is the branch's scene from the point of view of TS1.

[profile instance of VSI information]

Next, the detailed content by description VSI information.As described above, streptostyly content is configured to including by content Data and multiple scenes of VSI information composition, described VSI information is the control information relevant with the reproduction of content-data.Here, As shown in Figure 9, set up VSI information by scene, and provided with the form of such as XML (extensible markup language) document VSI information.

VSI information includes reproducing the required information (URL of the content-data of related scene for activate related scene (URL) etc.) with the relevant multiple Event element of event for being transformed into another scene from the situation of presence, Token (token) element for user authentication, etc..

Event element is included therein change in effective time range and spatial dimension at least to branch's scene The relevant bridge element of the individual bridge with the user interface defining for being changed to another scene and with indicate another The relevant one or more branches element of the branch of scene.

Bridge element includes defining the information of UI during scene branch.

Branch's element includes the information (example needed for for being changed to the branch's scene carrying out branch from related scene As the URL of the VSI information of branch's scene).The VSI information of branch's scene also includes similar information.For example, the VSI of branch's scene Information may include the information for being changed to the branch's scene carrying out branch from branch's scene further.

Here, show the detailed description of VSI information in Figure 10 to Figure 13.Figure 10 is the whole rule illustrating VSI information The table of model.

VSI information is set up by scene, and mainly include with regard to the metadata of scene and include in scene point The relevant Event element of the event of propping up and token element.

As the metadata with regard to scene, it may for example comprise for identifying the information of scene, for distinguishing the industry providing scene The information of business operator, the information for identifying the information of content-data of scene or the medium type with regard to scene.Pass through Provide the information of the medium type with regard to scene, the information with regard to medium type is referenced and controls in content playback unit 11 Reproduce, and content playback unit 11 becomes compatible with multiple medium types.

In addition, the Event element including in scene specification as shown in Figure 11 is defined further.Event element bag Include the metadata with regard to event, bridge element used in event and with can make to be changed to it from this event The relevant branch's element of branch's scene.

Figure 12 illustrates detailed further including the bridge element in Event element.Bridge element is definition The information of user interface during event activation.Therefore, it is included therein for showing the information needed for bridge picture.

In addition, figure 13 illustrates detailed further including the branch's element in Event element.In event unit Element includes one or more branches element.In addition, include the information of the medium type with regard to scene etc. in branch's element. By providing the information of the medium type with regard to scene, it is capable of the medium type of the scene of assigned finger destination.

Though it is assumed that having with the font size of each branch being related in bridge picture, font type, font color etc. The information closed is included in bridge element, but configures not limited to this, and such as these information can be included in respective point In Zhi Yuansu.

[type of scene]

Next, the type of the scene that the streptostyly content reproduce in content playback unit 11 includes will be described in.

Configure the streptostyly content reproducing in content playback unit 11 by substantially linking multiple scenes.Now, As the content-data of corresponding scene, using such as moving image, rest image, lantern slide, application and broadcast.

From the branch starting to content-data of the reproduction of the content-data of scene, stopping or terminate to continue a scene Reproduce.As scene reproduce in remote control operation, take for example stop operation, input operation, pausing operation, FF operation, FR operation, skip operation and play operation.

Stop operation is for stopping the operation reproducing.When execution, this stops operation, the reproduction of streptostyly content is stopped Stop, and picture returns to the picture of display before the activation of streptostyly content.

Execution input operation is to check the scene branch in such as event topic time range (or spatial dimension).When When executing input operation in event topic time range or spatial dimension, bridge picture is shown.

Pausing operation, FF operation and FR operation are similar with those in common content reproduction.That is, work as executing time-out During operation, the reproduction of the current content reproducing is hung.In addition, FF operation and FR operation are options.If content is operated with FF Operate compatible with FR, then will reproduce lower content F.F. when executing FF operation, and will be under reproduction when executing FR operation Content is refunded.

When executing skip operation in reproducing in content, content jumps to the scene of the beginning timing of next event.Play Operate and recovered for the pausing operation in reproducing from scene.

In addition, as described above, being classified to the content-data of scene based on medium type, for example using moving image, Rest image, lantern slide, application and broadcast.

Configure moving image scene by the dynamic image content based on moving image and audio frequency.Now, moving image Corresponding at least one of 2D (dimension) content and 3D content.

In addition, it is desirable to by this scene of disengaging that such as gets off, such as pass through in motion diagram in the reproduction of moving image scene The last picture of picture is transformed into original scene or the ending of streptostyly content after being shown.If additionally, referred to by VSI information Determine event, then input operation is executed by the theme time of event (or in theme space) and show specify another The bridge picture of scene.

Rest image scene is to be joined by a rest image of the form Ji Yu such as JPEG (JPEG) The scene put.When rest image scene is reproduced, rest image is as content-data on the whole picture of display portion 40 Shown.Rest image scene can be applied to the scene of all-links type, although the link type based on scene point Class will be described later.In the case of rest image scene, make to take off when user executes input operation in scene reproduction From this scene.In addition, if specifying event in the VSI information of rest image scene, then the input behaviour by being executed by user Make to show the bridge picture for specified another scene.

Configure lantern slide scene by one or more rest images.When lantern slide scene is reproduced, rest image is made Shown on the whole picture of display portion 40 for content-data.Then, switched with preassigned time interval order The display of each rest image.When display includes last rest image in slide content data, by for example Return to the original scene of streptostyly content or ending terminating the reproduction of this scene.

In addition, application scenario is the scene by application configuration.The example of application used herein includes Widget application With Java (registration mark) application.

Broadcast scene by being configured via the broadcasted content that radio network 22 receives from broadcaster 15, and only by It is defined as branch's scene.When being caused to the branch of broadcast scene, broadcasted content is shown in display portion 40.

As shown in figure 14, broadcast scene is defined by branch's element of VSI information.Specifically, in VSI information, Described in position (location) attribute of login (entry) element of branch's element of Figure 13, the URI with regard to broadcast is (unified Resource identifier), and thus specify specific channel.This URI from the beginning of the such as scheme of " dvb " or " arib " etc, and For example after the separator by colon, resource is indicated based on the form by schema definition.

In the branch to broadcast scene, for example, selecting and showing after the broadcasted content of specific channel it is desirable to pass through The end of such as streptostyly content is departing from related scene.

[type of event]

Next, the type of event will be described with reference to Figure 15 to Figure 20.

Event is classified into five types, i.e. time-event, spatial event, spatio-temporal event, absolute clock time-event, M- time-event during absolute clock.Although in addition, substantially event is used for the operation executing by user based on time or sky Between lead to be changed to another scene in the region that defines, but also define no matter how user operation automatically leads to scene The automatic event of conversion.

First, time-event refers to by the starting point on the time shaft of scene and end point certain time zone detached. In VSI, time-event is defined by starting point and end point.For example, as shown in Figure 15, if arranged at event 1 To the link of scene S2, then, when user's execution input operation in the reproduction in scene S1, determine that user executes input operation Whether timing is in the event procedure (leg) specified by VSI.Then if it is determined that this is regularly in the event procedure specified by VSI In, then the bridge picture specified by VSI information is shown.Then, the scene of another scene S2 being specified by user operation is again Now it is performed.

Spatial event is the event by the region instruction on the image spacing of scene.In VSI information, spatial event by The top-left coordinates of rectangular area and lower right coordinate are defined.Mainly when scene is rest image scene using spatial event. Alternately, in the case of moving image scene, when event is effective in the whole time course of scene, this event is claimed Make spatial event.For example, as shown in Figure 16, defined in rest image scene S1, two events are event 1 and event 2.When In the reproduction of this rest image scene S1 during user's execution input operation, determine this timing cursor position whether by In the rectangular area of event of VSI definition.Then if it is determined that cursor position is in event area, then the bridge specified by VSI Picture is shown.Then, if specifying scene, another scene S2 specifying by user operation here by user operation Reproduction start.

Spatio-temporal event is the event in the time on the time shaft of scene by the rectangular area instruction on image spacing.? In VSI, spatio-temporal event is sat by the top-left coordinates of rectangular area in the starting point on time shaft and end point and picture and bottom right Target combination is defined.Only in the case of moving image scene effectively, it is related to the concept in time and space to spatio-temporal event. In fig. 17 it is shown that the spatio-temporal event in scene S1：Event 1 and event 2.When user execute in the reproduction of this scene S1 defeated When entering to operate, determine that user executes the timing of input operation whether in the time range of the event being defined by VSI, and determine This timing cursor position whether in the spatial dimension of the event being defined by VSI.Then if it is determined that they are in event model In enclosing, then the bridge picture specified by VSI is shown.Then, if specifying scene here by user operation, by using The reproduction of another scene S2 that family operation is specified starts.

In addition, for example, when in VSI information, spatial event or spatio-temporal event are identified, cursor can be in display picture Shown.Although being used for showing that this light calibration method depends on embodiment, it is configured such that for example can pass through The up/down of the input unit of operation part 34 or such as remote control/left/right key etc. mobile cursor on picture.

Absolute clock time-event is independently of the thing that the process of scene occurs in the specific date pre-setting and time Part.For example, as shown in Figure 18, if the start_time of the absolute_timeframe element in the Event element of Figure 11 " 201,0/5,/12 13 are arranged in attribute:55 " " 201,0/5,/12 14 are arranged and in end_time attribute:00 ", then exist The 13 of 2010/5/12:55 to 14:Time of origin-time-event event 1 in 5 minutes of 00.In this case, when in scene In the reproduction of S1 during user's execution input operation, determine that user executes the timing of input operation whether from 201,0/5,/12 13: 55 to 201,0/5,/12 14:In 00 time range.If it is determined that this is regularly in this time range, then bridge picture is shown Show.Then, if specifying scene here by user operation, the reproduction of another scene S2 being specified by user operation is opened Begin.

Now, for example can be using broadcast scene as making branch's destination scene of being changed from scene S1 to it S2.Specifically, as shown in figure 19, in the case of there is absolute clock time-event in the middle of scene, when from bridge picture During the broadcasted content of selection arbitrary channel, display is switched to broadcasted content from streptostyly content, thus broadcasted content is shown.This In display broadcasted content can be the specific channel broadcasted in this switching timing broadcasted content, or can be at certain The broadcasted content that specific clock time is broadcasted.In addition, when content is switched to broadcast in the beginning timing of certain program by expectation So that there is absolute clock time-event before the beginning clock time of broadcast program during content.

During absolute clock, m- time-event is the absolute clock time-event occurring only at time-event, and it is to pass through Starting point on the time shaft of scene and end point carry out detached scheduled time region.In other words, it can also be said that absolute clock When m- time-event be if time-event and absolute clock time-event and (AND) condition meet, event.Example As, in the case of Figure 18, if current time is outside the scope of the time zone being defined by time-event, absolute clock When m- time-event do not occur, and separated m- during absolute clock by the starting point on the time shaft of scene and end point Time-event, (while in from 2010/5/1213:55 to 201,0/5,/12 14:In 00 time range).Specifically, example As being capable of following scene.Certain ad-hoc location in user is positioned at operating room in Virtual Space and current time change When becoming the specific clock time that such as program starts clock time, during absolute clock, m- time-event occurs, and user is drawn It is directed at the movie theatre after operating room.

By this way, by time-event m- during absolute clock, when current time becomes specific clock time, solely Stand on the process of scene, the event that enables to occurs in special scenes.

When hereinbefore, for time-event, spatial event, spatio-temporal event, absolute clock time-event and absolute clock M- time-event, relate generally to for by user operation so that the event changed to another scene is explained.So And, as this event, not only by user operation so that the event changed to another scene is defined, and automatically make The automatic event changed to another scene is defined.Next, this automatic event will be described.

Automatic event is no matter user operation is how automatically so that the event changed to another scene.If automatic thing Part is defined by VSI, then when identifying that current time comes in the time range being defined by automatic event, no matter user Operation how, and the reproduction of related scene is automatically stopped, and bridge picture is displayed such that and is changed to another scene.

For example, there is the event 1 as automatic event defined in shown in fig. 20 scene S1.When the reproduction in scene S1 Middle identification current time comes into by when in the range of the event 1 of the VSI information definition of scene S1, by VSI information definition Bridge picture is shown, and and then the reproduction of scene S2 automatically begin to.

For example, when expecting the moving image after replacing certain timing in scene S1, using such automatic event thing Part 1.In addition, for example, broadcast scene is used as the scene of the branch destination of automatic event.In this case, for example can Enough realize following scene.Specifically, when certain ad-hoc location being located in operating room in user in Virtual Space and current when Between when becoming the specific clock time that such as program starts clock time, during absolute clock, m- time-event occurs, and separately Outward, user is directed to by the movie theatre after operating room by automatic event.Then, start to see at movie theatre below See broadcasted content.

[pattern of bridge]

Next, the bridge in Event element will be included with reference to Figure 21 description.Figure 21 is an example illustrating bridge Diagram.

Bridge is UI during scene branch, defines the bridge element in VSI information by event.In addition, bridge element is fixed When institute in event range when user is in execution input operation in event range or at current time entrance automatic event for the justice Picture during the scene branch providing.

For example, in the example of Figure 21, based on the content-data of scene S1 of scene reproduced while use When family executes input operation in the event picture 182 being in event range, by the first bridge picture of bridge element definition 184 are shown.

In the first bridge picture 184 in figure 21, in the UI being defined and included by bridge element user operation Picture configuration in show two options, i.e. return to former for the option changed to a branch scene S2 and being used for The option of primordium plinth scene.Here, if user selects the option for being changed to branch scene S2 by input operation, The the second bridge picture 186 then passing through only to delete the UI acquisition of option is shown.Then, when for starting branch scene S2's When being provided with of reproduction, the reproduction of branch scene S2 starts, and branch's scene starting image 188 is shown.

[operational instances of content reproduction system]

Figure 22 is the explanation diagram of an example illustrating streptostyly content.Figure 23 is the streptostyly content illustrating Figure 22 The sequence chart of one example of rendering operation.

Streptostyly content shown in Figure 22 have based on scene termination scene TS1 and circulation scene LS1, and Circulation scene LS1 is from the event branch in certain timing terminating scene TS1.From VSI server 13 different from each other with each other not With content server 14 provide terminate the content-data of scene TS1 and VSI information and circulation scene LS1 content-data and VSI information.

First, the display controller 53 request Web server 12 transmission contents list picture of content playback unit 11 (S101).Subsequently, in response to the request from content playback unit 11, Web server 12 provides the HTML including contents list Document (S102).Here, if the user 300 with reference to the contents list picture providing executes in contents list selection streptostyly The operation (S103) held, then the function (S104) of display controller 53 activation VSI client 50.As described above, VSI client 50 It is the concept of the function including the control information getter 51 in Fig. 7 and Render Control 52.

Then, in response to the request from display controller 53, VSI client 50 request VSI server 13A transmission with by The streptostyly content corresponding VSI information (S105) that user 300 specifies.From VSI client 50 requested transmission VSI information VSI server 13A transmits the corresponding VSI of scene TS1 with the reproduction first of the streptostyly content described in this request message Information (S106).Then, receive the received VSI information (S107) of VSI client 50 analysis of VSI information.In VSI information In, described the content-data storage where information of related scene to indicate.VSI client 50 will flow rendering requests with regard to The information of the storage location of content-data is input to reproduction part 32 (S108) together.

Reproduction part 32 is based on the information request content server 14A receiving from VSI client 50 to activate streaming (S109).In response to the request of streaming activation, content server 14A starts and the corresponding content-data of scene TS1 specified Streaming transmission (S110).In addition, if the centre of the reproduction in the scene TS1 being transmitted by this streaming for the user 300 is held Row input operation (S111), then the display based on the bridge control of element bridge picture including in VSI information for the VSI client 50 (S112).Here, in bridge picture, show for the option changed to the circulation scene LS1 as branch's scene and For returning to the option of the termination scene TS1 as original base scene.

If user 300 executes the operation (S113) selecting branch's scene to this bridge picture, VSI client 50 is asked VSI server 13B transmission and the corresponding VSI information of circulation scene LS1 as the branch's scene being selected by user 300 (S114).In response to asking the message of VSI information, VSI server 13B is to VSI client 50 transmission and LS1 pair, the scene specified The VSI information answered.

Receive the received VSI information (S116) of VSI client 50 analysis of VSI information.Then, VSI client 50 From the storage location of the content-data as the circulation scene LS1 of branch's scene for the VSI acquisition of information, and will flow rendering requests with Information with regard to the storage location of content-data is input to reproduction part 32 (S117) together.Now, VSI client 50 holds pass In the information of conversion timing and the VSI information of basic scene TS1.In response to this rendering requests, reproduction part 32 is to content service Device 14B sends the request (S118) of the streaming activation for circulation scene LS1.

Receive the streaming (S119) that streaming activates the scene LS1 that the content server 14B asking starts to specify.When At the end of the reproduction of scene LS1, VSI client 50 automatically begins to the reproduction of original base scene TS1.Specifically, by making With holding the VSI information of information with regard to conversion timing and basic scene TS1, VSI client 50 control reproduction part 32 from Conversion timing restarts the reproduction (S120) of basic scene TS1.

In the example of Figure 23, VSI client 50 holds the VSI information itself of basic scene TS1.Therefore, as point After the reproduction of the circulation scene LS1 of scene terminates, VSI client 50 is not in the case of needing to obtain VSI information again The reproduction of basic scene TS1 can be restarted.Compare, it is also feasible that depending on the performance of content playback unit 11, VSI client 50 only holds the information of the storage location with regard to VSI information.In this case, VSI client 50 is based on and holds The information with regard to storage location having obtains VSI information again, and can restart the reproduction of basic scene TS1.

According to the control of VSI client 50, reproduction part 32 request content server 14A is from the conversion of basic scene TS1 The streaming (S121) of timed activation content-data.Then, in response to this request, content server 14A restarts basic feelings Streaming transmission (S122) of scape TS1.

It is described above the behaviour of the content reproduction system 1 of an example for streptostyly content shown in Figure 23 Make.Next, the operation by reference Figure 24 and Figure 25 description content transcriber 11.Figure 24 and Figure 25 is to illustrate that content reproduces dress The flow chart of the operation put.

The reproduction of streptostyly content by the operation by user and start the operation of the flow chart of Figure 24.Work as command chaining During the reproduction of direct type content, the VSI client 50 of content playback unit 11 obtains VSI information (S201) from specified URL.So Afterwards, VSI client 50 analyzes the VSI information (S202) being obtained by VSI client 50.

In step S203, VSI client 50 determines the medium type of scene based on VSI information.As described above, in VSI There is the medium type of related scene described in information.Here, suppose that the medium type of scene is five types, i.e. application (App), rest image (Still), lantern slide (Slide), moving image (Video) and broadcast (Broadcast).

If determining that in step S203 the medium type of scene is application, process enters step S204.In step In S204, VSI client 50 performance objective is applied.When the medium type of scene is application, chain at the end of the execution of application The reproduction of direct type content terminates, this is because the type defining scene is to terminate scene.

If determining that in step S203 the medium type of scene is rest image, process enters step S205.In step In rapid S205, VSI client 50 display target scene rest image.

If determining that in step S203 the medium type of scene is lantern slide, process enters step S206.In step In S206, VSI client 50 activates the display of target context lantern slide.

If determining that in step S203 the medium type of scene is moving image, process enters step S207.In step In rapid S207, VSI client 50 activates the reproduction of target context streaming.Now, VSI client 50 according to situation from specified Time location starts streaming and reproduces.

If determining that in step S203 the medium type of scene is broadcast, process enters step S208.In step In S208, display controller 53 controls tuner 36 to select the position with login (entry) element in branch's element (Location) the corresponding channel of the URI described in attribute.Thus, with the corresponding vision signal of channel being selected by tuner 36 It is imported into selector 35 with audio signal.In addition, display controller 53 control selections device 35 is by the input purpose of selector 35 Ground is switched to Video Decoder 38 and audio decoder 39 side from reproduction part 32 side.Thus, wide with specified channel Broadcast the corresponding video of content to be shown in display portion 40, and its audio frequency is exported from loudspeaker 41.

As described above, broadcast scene is only defined as branch's scene.In addition, in the branch to broadcast scene, for example, Expect selecting and departing from related scene by the end of such as streptostyly content after showing the broadcasted content of specific channel.

When starting the reproduction of rest image, lantern slide or moving image respectively in step S205, S206 or S207, place Reason enters step S209.In step S209, VSI client 50 determines whether user 300 by using operation part 34, input Device etc. performs up/down/left/right key operation.If determining that in step S209 up/down/left/right key operation is performed, Then display controller 53 display highlighting and according to the mobile cursor position of key operation (S210).Terminate in the process of step S210 When, process and return to step S209, and the process of execution step S209 and subsequent step.

Then, if determining that in step S209 up/down/left/right key operation is not performed, process enters step S211.In step S211, VSI client 50 determines whether to perform decision key operation.Determine if determined in step S211 Determine key operation to be performed, it is determined whether perform decision key operation (S212) in subject eventses.

As this subject events, above-mentioned time-event, spatial event, spatio-temporal event, absolute clock time-event and absolutely Clock time-time-event is corresponded to therewith.In the case of automatic event, no matter how user operation automatically leads to another The conversion of scene.

Determining that key operation is not performed in subject eventses if determined in step S212, processing and again returning to The determination of step S216.Compare, determining that key operation is performed in subject eventses if determined in step S212, processing Enter step S215 in Figure 25.

On the other hand, determine that key operation is not performed if determined in step S211, next VSI client 50 Determine whether scene terminates (S213).If determining that in step S213 scene is not over, and processes and returns to step S209 Determination process.That is, the process of step S209 to S213 is repeated, until in subject eventses, execution determines key operation Or the reproduction of scene terminates.

Then, if VSI client 50 determines that the reproduction of scene finishes in step S213, process enters step S214.In step S214, VSI client 50 determines whether present case is streptostyly end of text situation.Specifically, chain Direct type end of text situation is the scene under reproducing is the situation terminating scene.

If determining that in step S214 present case is streptostyly end of text situation, the reproduction knot of streptostyly content Bundle.Compare, if determining that in step S214 present case is not streptostyly end of text situation, process enters in Figure 25 Step S215.

In step S215, VSI client 50 shows bridge.Here, VSI client 50 determines until this timing reproduction Whether scene is circulation scene and whether the reproduction circulating scene terminates (S216).If determining this scene in step S216 End is the end of circulation scene, then VSI client 50 specifies the scene recovering position (that is, conversion timing) and returning to destination VSI URL (S217), and process enter step S227.

On the other hand, if determining that in step S216 this scene terminates is not the end of circulation scene, next VSI Client 50 determines whether the bridge of display in step S215 is direct bridge (Immediate Bridge) (S218).It is based on In step S215, the bridge unit of the bridge of display usually executes this determination and processes.

If determining that in step S218 the bridge of display in step S215 is direct bridge, process enters step S225.Compare, if determining that in step S218 the bridge of display in step S215 is not direct bridge, next VSI client 50 determines whether that user performs up down key operation (S219) by using operation part 34 or input unit.So Afterwards, if determining that in step S219 up down key operation is performed, display controller 53 operates mobile light according to up down key Mark (S220).Compare, if determining that in step S219 up down key operation is not performed, process enters step S221. In step S221, VSI client 50 determines whether to perform decision key operation.

Determining that key operation is not performed if determined in step S221, processing the process returning to step S219. Comparing, determining that key operation is performed if determined in step S221, process enters step S222.In step S222, VSI client 50 determines that whether the option of selection is the option for returning to original scene.

If determining that in step S222 the option of selection is the option for returning to original scene, processing and returning to The operation of step S203 in Figure 24.Compare, if determine in step S222 selection option be not intended to return to former The option of beginning scene, then process enters step S223.In step S223, VSI client 50 determines the scene of conversion destination Whether it is circulation scene.

If determining that in step S223 the scene of conversion destination is not circulation scene, VSI client 50 discharges VSI Information (S224).Compare, if determining that in step S223 the scene of conversion destination is circulation scene, VSI client 50 are held in the VSI URL of scene and the recovery information (S225) that current timing reproduces.

Then, VSI client 50 specifies the VSI URL of scene and the streaming starting position of conversion destination, and tests Token is simultaneously set to VSI URL (S227) by card token.At the end of step S227, process enters step S201.

This is the end of the description of streptostyly content reproduction processes.

According to above-mentioned streptostyly content reproduction processes, moving image, quiet can be shown according to the medium type of scene The only any one content in image, lantern slide, application and broadcast.In addition, when time-event, spatial event, spatio-temporal event, When any one event in m- time-event when absolute clock time-event and absolute clock occurs, enable to scene and turn Change to another scene.

It is described above the function of content reproduction system 1 and the detailed description of streptostyly content.Using this content again Existing system 1 can provide the various streptostyly content cooperating with broadcasted content.Therefore, it is possible to provide unprecedented new in Hold.So, next, the example of the streptostyly content that description can be provided by application content playback system 1.

For example it will be assumed that following situation, wherein, as shown in figure 26, (it is the work being provided by certain news program to scene S1 The main scene of the Virtual Space of room roaming) start, and user moves in Virtual Space.When user is located in this Virtual Space Certain ad-hoc location and when m- time-event occurs when absolute clock time-event or absolute clock, user is from this position quilt Guide to movie theatre.In this movie theatre, broadcast scene starts and broadcasted content is watched.

As described above, by m- time-event when absolute clock time-event or absolute clock, so that event is pre- The specific date first arranging and time occur, and so that are switched to broadcasted content in the conversion to another scene.Cause This, using the teaching of the invention it is possible to provide there is the streptostyly content of various scene.

In the above description, it is dynamic image content, rest image content, slide content, application based on content-data Any one hypothesis in content and broadcasted content is explained.However, content-data not limited to this, and can include Such as audio content of speech, radio programming, music etc..
