Fig. 1 is the flow chart according to the method for link identification of creating in digital program of the embodiment of the invention.
As shown in Figure 1, at step S110, confirm that digital program is to be associated with link information.Here, digital program for example can be an interactive TV program, also can be other forms of program.The multi-form of digital program is not construed as limiting the invention.The substance of link information is the URL (URL(uniform resource locator)) that the application in the digital program will be visited, and authorization message etc.For example,
<URL>http://www.philips.com/video/brand.wmv</URL>
<Authorization>
<Name>user1</Name>
<Code>T3r6ygHt</Code>
</Authorization>
Step S110 for example can comprise a step that receives an instruction, comprises the relevant information of a link identification in the instruction that receives.Link identification is used to show that this digital program is to be associated with link information.After receiving this instruction, confirm that this digital program is to be associated with link information.This instruction for example can be picked up from digital program producer's input.Such as, the digital program producer can import a file.The filename of this document for example adopts following form:
dvb.IP.oooooooo.aaaa
Wherein " oooooooo " is the organization identification of an application, is the long hexadecimal strings of 8 characters, and " aaaa " is the sign of an application, is the long hexadecimal strings of 4 characters.
Can arrange:, can confirm that this digital program is to be associated with link information if detect the filename of having imported above-mentioned form.
Whether in addition, also can detect specific button is pressed.For example, can stipulate that to indicate this digital program be to be associated with link information to the digital program personnel by pressing specific button.
Certainly, also can confirm whether this digital program is associated with link information by digital program is resolved automatically.Then, at step S120, integrated this link identification is in this digital program.Multi-form at link information, can integrated in different ways this link identification in this digital program.Hereinafter will have a detailed description.
Then,, transmit this digital program, that is, the digital program transport streams that is integrated with link identification is sent on the transmission medium at step S130.Transmission medium for example can be satellite network, fixed-line network, cable TV network etc.
Introduce the link identification of several forms below, and the mode of integrated link identification in the digital program.
The link identification of first kind of form
For example, can be saved in the link information that will relate in the predefined link information descriptor.This link information descriptor is the link identification of first kind of form in the present embodiment.This descriptor in a service information segment of digital program transport streams by pre-defined.By pre-defined this descriptor in the service information segment in digital program transport streams, realized the step of integrated link identification in the digital program easily.Here, service information segment for example can be the AIT (application information table) etc. of regulation among PMT (Program Map Table), the MHP (multimedia home platform) of MPEG-2 regulation.
The structure of PMT is as shown in table 1.

As shown in table 2, in the AIT section, can define M descriptor and M2 descriptor that is used for application-specific that is used for whole program.
As can be seen from Table 2, two class descriptors are arranged in the AIT section, promptly appear at public descriptor and the application descriptor that appears in the application cycle (application loop) in the public circulation (common loop).Public descriptor is applicable to whole digital program.Application descriptor is applicable to specific application.
Except PMT and AIT, also can adopt the descriptor in other service information segment of digital program transport streams to transmit link information as link identification.
In the present embodiment, this descriptor that is used to transmit link information is called " link information descriptor ".For example, can be as shown in table 3 with the link information descriptor definition.
Table 3

| IPInfoDescriptor(){ | ||
| Descriptor_tag | 8 | uimsbf |
| Descriptor_length | 8 | uimsbf |

LinkInfo territory in the table 3 for example can comprise following information:
<URL>http://www.philips.com/Video/brand.wmv</URL>
<Authorization>
<Name>user1</Name>
<Code>T3r6ygHt</Code>
</Authorization>
LinkInfo in the table 3 also can omit.In this case, the descriptor of table 3 will only be used to show that digital program is associated with link information.Associated link information can be placed on other positions in the digital program transport streams, for example, can be placed on one and use in self.If associated link information is placed in this application self, then terminal can should be used for obtaining associated link information by opening this.
The link identification of second form
Certainly, also link information can be stored in the file.The file of having stored link information is called " link information file ".Link information file is the link identification of second kind of form in the present embodiment.Can store the information of a plurality of links in link information file.For example, link information file can comprise following content:
<！Link information file>
<Link>
<URL>http://www.philips.com/video/brand.wmv</URL>
<Authorization>
<Name>user1</Name>
<Code>T3r6ygHt</Code>
</Authorization>
<Redirect_type>1</Redirect_type>
</Link>
<Link>
<URL>http://www.philips.com/audio/brand.mp3</URL>
<Authorization>
<Name>user1</Name>
<Code>T3r6ygHt</Code>
</Authorization>
<Redirect_type>1</Redirect_type>
</Link>
...
Link information file can adopt the sentence structure based on XML.In link information file, can stored protocol information and other information.
The filename of link information for example can be " dvb.IP.oooooooo.aaaa ".Wherein, " oooooooo " is the organization identification of using, and is the long hexadecimal strings of 8 characters; " aaaa " is the sign of using, and is the long hexadecimal strings of 4 characters.
All link informations can be included in the link information file, also can be as required with the link information separate storage in different link information file.
Then, link information file is multiplexed in the digital program transport streams, sends terminal to digital program (containing application).By this multiplex process, realized the step of integrated link identification in the digital program.By broadcast head end and negotiation among terminals, terminal obtains link information file by digital program transport streams is carried out demultiplexing.
The link identification of the third form
The link identification of the third form is the combination of descriptor and link information file.This descriptor can be called " IP connects descriptor ".For example, it is as shown in table 4 I P can being connected descriptor definition.
Table 4
| Structure | Figure place | Implication |
| IPConnectionDescriptor(){ | ||
| Descriptor_tag | 8 | uimsbf |
| Descriptor_length | 8 | uimsbf |
| Type | 8 | bslbf |

Territory in the table 4 " Type " can value be 0 or 1.When the Type value is 1, show to comprise link information file in the digital program transport streams.When the Type value is 0, show not comprise link information file in the digital program transport streams.
Like this, only multiplexing under the situation of link information file in digital program transport streams when the broadcast figure program, just the Type territory that connects in the descriptor of IP is set to 1.Thereby, terminal only the IP in detecting corresponding service information segment to connect Type territory in the descriptor be under 1 the situation, demultiplexing link information file from digital program transport streams.Terminal needn't always check whether occur link information file in the digital program transport streams that is received.On the contrary, terminal only needs the information on services of digital program transport streams is once analyzed, and promptly knows whether contain link information file in the digital program transport streams that is received.Improved the operating efficiency of terminal.
The link identification of the 4th kind of form
The link identification of the 4th kind of form is the combination that IP connects descriptor, link information descriptor and link information file.For example,, define IP and connect descriptor whole digital program, be used for the designation number transport stream whether multiplexing link information file.To each application in the digital program, define a link information descriptor respectively, be used to indicate filename corresponding to the link information file of this application, for example as shown in table 5:
Table 5
| Structure | Figure place | Implication |
| IPInfoDescriptor(){ | ||
| Descriptor_tag | 8 | uimsbf |
| Descriptor_length | 8 | uimsbf |
| Info_filepath | 256 | bslbf |
| } |
" Info_filepath " territory in the table 5 is used to indicate the filename of corresponding link information file.Alternately, all link information file can be stored in the fixed schedule (for example root), thereby can economize " Info_filepath " territory in the sketch form 5.Certainly, if broadcast head end and terminal are held consultation with regard to link information file name and file path, also can economize " Info_filepath " territory in the sketch form 5.
Then, to each application in the digital program, prepare a link information file respectively, and these link information file are inserted in the digital program transport streams.
The link identification of above-mentioned four kinds of forms just for example.The one skilled in the art it is contemplated that other forms of link identification.Multi-form link identification is not construed as limiting the invention.
In various links, some link can be redirected, and some link can not be redirected.For example, mp3 file can be play by STB (set-top box) and PC (personal computer), and uses and can only be play by the STB with MHP middleware from the MHP of internet, but can not be play by PC.
So, can in previously described link information descriptor or link information file, be provided with one and be redirected sign, promptly＜Redirect_type〉mark, be used to show that corresponding link information can be redirected.For example,＜and Redirect_type〉mark can be:
<Redirect_type>1</Redirect_type>
At＜Redirect_type〉the mark value is under 1 the situation, to show that this link can be redirected, and can be used by miscellaneous equipment.For example, terminal can be redirected to this link information PC (personal computer), and the content that request PC downloads and storage is linked.
At＜Redirect_type〉the mark value is under 0 the situation, to show that this link can not be redirected, and promptly can only be used by terminal.
About how with link information file multiplexing (integrated) in digital program transport streams, for mpeg 2 transport stream, can link information file be inserted in the transport stream by the DSM-CC agreement.
Those skilled in the art should be understood that in this area, integrated link identification in the digital program transport streams different modes and the different agreement that is adopted be not construed as limiting the invention.
Fig. 2 is the flow chart according to the method for the record digital program of the embodiment of the invention.
As shown in Figure 2, at step S210, from transmission medium, receive a digital program transport streams.Here, digital program is an interactive TV program, certainly, also can be other forms of program.The multi-form of digital program is not construed as limiting the invention.At step S220, discern the link identification in this digital program transport streams.Link identification for example can be that preamble is with reference to the described various forms of link identification of Fig. 1.At step S230,, obtain corresponding link information according to this link identification.Link information for example can be included in previously described link information descriptor, IP and connect among one or more in descriptor and the link information file.Broadcast head end and terminal can be predetermined in advance with regard to the concrete load mode of link information, thereby operate accordingly.Here repeat no more.
At step S240, obtain the pairing network data of this link information from the internet.At step S250, produce the mapped file of the relation between this network data of indication and this link information.Then, at step S260, be recorded in digital program that step S201 receives, the network data of obtaining at step S240 and the mapped file that produces at step S250.The digital program that is received, the network data of being obtained and the mapped file that is produced can be recorded in same the equipment (as the set-top box of personal digital video recorder or tape storage), also can be recorded in the different equipment (for example personal computer).
For example, if detect＜Redirect_type〉value of mark is 1, then the network data of obtaining among the step S240 can be sent to a personal computer, and store these network datas by this personal computer.
Alternately, if detecting the link identification of discerning in step S220 comprises＜Redirect_type〉mark and＜Redirect_type the value of mark is 1 o'clock, then the link information that obtains among the step S230 can be sent to a personal computer, and order this personal computer to download and write down the pairing network data of this link information.
Indicate a personal computer to carry out corresponding downloading process based on such consideration.Network browsing sometimes with watch the movable inconsistent of digital program resemble the interactive television.The display effect of some webpage on television set is enough not good.Even some television set is not supported the latest network form.But broadcaster is another directly to be attempted to provide extra data content by itv program, attracts the televiewer to visit specific website.For example, broadcaster can be inserted into certain figure or text (not being actual URL) in the itv program, offers the televiewer with transport stream.The televiewer can select to watch or download the web page contents (preamble claims " network data ") with these figures or text link.Some web page contents (as " sudden strain of a muscle " file) inconvenience is play on television set.So the user can select these web page contents are downloaded on the equipment (as personal computer) that is fit to these contents of broadcast, so that watch later on.Spectators may be disinclined to open personal computer when watching itv program, also may have little time to open personal computer, so the web page contents of broadcasting is downloaded.Yet according to method shown in Figure 2, when the record interactive television program, the network data that needs can be downloaded in the personal computer is automatically downloaded.If linked to as if actual content, then can with the content intact of reality download in the personal computer.If linked to as if a webpage, also can in the browser of personal computer, increase by one the sensing this webpage bookmark, thereby the user always can see the latest edition of this webpage.
Fig. 3 is the flow chart according to the method for the playing digital program of the embodiment of the invention.
As shown in Figure 3, at step S310, play a digital program.As mentioned before, this digital program can be an itv program, can have one or more application.Application in the digital program connects relevant with network.That is to say that this digital program is associated with link information.
At step S320, move the application in this digital program.
At step S330, judge to use whether need to obtain network data.
If the judged result of step S330 is for being, then handles and proceeding to step S340; Otherwise, handle proceeding to step S360.
At step S340, inquiry is stored in the mapped file of this locality, and the network that obtains application need foundation connects and is stored in local network data and maybe needs from the corresponding relation between the network data of internet download.
At step S350,,, perhaps obtain network data, and reproduce the network data that is obtained from the internet perhaps from this locality according to the corresponding relation that obtains at step S340.
At step S360, judge whether the digital program of being play finishes.
If the judged result of step S360 is then handled and is turned back to step S330 for not; Otherwise processing finishes.
Above-mentioned steps S340 is optional.
Above-mentioned steps S320 also is optional.Can directly reproduce and be stored in local network data.
To be stored in local network data in order using, can in playing device, to set up an agency together with digital program.When broadcast is stored in local digital program and application when beginning to obtain network data, this agency will determine from the internet still to be to obtain relevant network data from local storage by the mapped file of analyzing stored in this locality.
During live broadcast, interactive application will connect the content that reads link from the internet by the internet.When storage has the digital program of the link of embedding and during from the local storage playing digital program, uses and also will attempt to be connected to the internet.Therefore, should application code when storage is used its make amendment, or playing device (as player) must be redirected application to obtain network data from local storage.When storage is used it being made amendment is not a practicable solution, and this is because tape deck (as video tape recorder) needs to analyze all application codes.This is unsuitable for real time record, and if use with transport stream and do not store respectively, what for to amended application being multiplexed in the transport stream once more.
Under actual conditions, some linked contents can be stored in this locality, and some linked contents can obtain from the internet.
