Embodiment
Below quoted figures is described preferred implementation of the present invention here.In the following description, known function or structure will not be described in detail, because they will make indigestion of the present invention in unnecessary details.
The present invention adds the preview data of preview service in the additional information or control information that is different from broadcast data to, transmits at digit broadcasting system being used for.As previously mentioned, propose to be used for the multiple transmission standard of digital broadcasting, comprised DAB, DVB and DMB.The present invention will be described in the context of DVB system and execution mode thereof, but the present invention is not limited thereto.Therefore, it should be clearly understood that the present invention can be applied to the system of any kind, as long as they as described belowly are configured and operate.
The transmission of the preview data of serving according to the preview of preferred implementation of the present invention will be described now.
In aforementioned ESG data model, the preview data use is obtained one of information element (IE) of fragment and just " is switched and support " (Zapping Support) element, sends.
Switch and support it is that definition is used in the IE field of obtaining the transmission of fragment switch data.When the user in the DVB system during switching channels (channel), switch data is shown.Owing to before the channel output service data that changes, also need some seconds, during these seconds, tentation data be shown to the user.These data are commonly called switch data (zapping data).Switch data can be image, music or moving image.Typically, switching the support element utilizes the required session information of visit URI that the field of quoting (reference) of Session Description Protocol (SDP) is formed by the field of the universal resource identifier that switch data is provided (URI) with providing.
According to the present invention, switch and support that element is disposed like this, so that enable the transmission of preview data and switch data.Similar switch data, preview data can be image, music or moving image.Switch the link information of supporting element also to comprise the URI that indicates preview data and utilize required session information the quoting of visit URI SDP file.By this way, described terminal can be obtained preview data.
Be called as " outside the frequency band " (out of band) transmission at channel switch data that is different from the channel that is loaded with the ESG data or preview data (switching/preview data).Alternately, can send switching/preview data in the ESG data, this is called as " in the circuit " (inlined) transmission.If the size of switching/preview data is very big, then efficiency of transmission is low in the circuit, because it needs the outer physical resource of allocation.If the size of switching/preview data is very little, then transmission has reduced terminal and has quoted required step number of switching/preview data and time in the circuit.
To transmit in order supporting to use to switch in the circuit of supporting, to switch and support to be expanded to enable transmission switching/preview data in ESG stream.
Owing to switch to support it is the complex scenario of describing with extend markup language (XML), new signaling field is added to switch and supports to be included in classification of Data in the ESG data with indication.In this case, switch data and preview data can be included in the switching support of ESG data.The type of signaling field is not limited, thereby can enough any XML types describe.

Embodiment 2
Preview data uses the associated materials element to send, and this is basic ESG data.
In intended fragment, associated materials is quoted other media data.Specifically, associated materials is included in contents fragment 106, service fragment 102 and serves at least one of restrainting in the fragment 110.Associated materials is by the MediaLocator field of the position of the HowRelated field of the relation of indication between media data of quoting and respective segments, the media data quoted of indication and be used to represent that the Optional Field of advertising message forms.HowRelated and MediaLocator are compulsory for associated materials.
Can represent to transmit the two in outer transmission of frequency band and the circuit by enough associated materials.Associated materials comprises the signaling field of the classification of indication transmission data, or the classification of data that appointment in having field is transmitted.The type of signaling field is not limited, thereby can enough any XML types represent.For example, can state whether the data that indication is transmitted are attributes of preview data.
The existing field that terminal can mechanically be ended can be used to the classification of given transmission data.For example, existing field can be the HowRelated of associated materials.As shown in table 2, the type of HowRelated is ControlledTermType.For ControlledTermType, see also TVA standard " ETSI TS102822-3-1 ".
Table 2
| Field | Type |
| HowRelated | ControlledTermType |
If the classification of the data that HowRelated is transmitted by ControlledTermType indication, then the description of preview service can send with text.This sends text " preview data " in HowRelated.In this case, terminal determines simply that by its inter-process the data transmitted are texts, and does not know that the text represents preview data.The type of HowRelated is with Integer (integer) statement, and is as shown in table 3.
Table 3
| Field | Type |
| HowRelated | Integer |
If HowRelated uses " Integer " type to specify the classification of the data of being transmitted, described description can be adopted the form of integer.Just, the integer of indication " preview data " replaces text " preview data " itself.Terminal is determined the classification by the data of being transmitted of HowRelated performance by explain described integer according to pre-defined rule.For example, (Classification Scheme CS) is preset between transmitter and the terminal classification schemes, and wherein integer " 1 " is represented preview data, integer " 2 " expression logo (sign) data, and integer " 3 " expression ad data.Therefore, terminal determines according to HowRelated whether the data that sent by the associated materials element are preview datas.
The HowRelated in associated materials, any other field can be used to specify the classification of the data of being transmitted.And such field can adopt the type that is different from " Integer ", as long as it can discern the transmission of preview data.
The demonstration XML grammer of associated materials is given:
<RelatedMaterial>
<HowRelated
href＝″urn:dvb:ipdc:esg:cs:HowRelatedCS″>preview</HowRelated>
<MediaLocator>
<InlineMedia type＝″image/jpeg″>
<MediaData64>[base64 mime encoded picture]
</MediaData64>
</InlineMedia>
or
<MediaUri>cbms://foo.com/preview/123456</MediaUri>
</MediaLocator>
</RelatedMatrial>
Above-mentioned HowRelated grammer need comprise quoting of the Format Type of indicating HowRelated.For example, " urn:dvb:ipdc:esg:cs:HowRelatedCS " indicates quoting that the CS by DVB-IPDC (IP Data CastingIP data configuration) or DVB-CBMS (converging of broadcasting and mobile service) definition shows, and " HowRelatedCS " and CS table is formed according to DVB-IPDC (or DVB-CBMS) standard.The meaning of the specific integer that CS table appointment HowRelated can have.For the integer of setting in HowRelated, terminal can be quoted CS voting and decide integer and whether indicate preview data.
When above-mentioned XML syntactic representation string value " preview " during as HowRelated, HowRelated can be set to integer as mentioned above, such as " 1 " or " 2 ".MediaLocator provides preview data in the circuit or be provided for the link information of the preview data of transmission outside the frequency band in the MediaUri field in the InlineMedia field.At preview data is under the situation of InlineMedia form, it has multipurpose internet mail expansion (MIME) type that is called " image/jpeg ", and MediaData64 field indication preview data is " base64Binary " form by the MPEG7 definition.
MediaUri provides the link information that is placed in the preview data in predetermined DVB-IPDC (or DVB-CBMS) server, such as " cbms: //foo.com/preview/123456 ".
