Description
Technical field
The present invention relates to the digital television techniques field, be meant a kind of method and apparatus that in digital TV data, adds ad data especially.
Background technology
Along with the development of Digital Electronic Technique, increasing digital technology is applied in the middle of the fields of society.
Application at digital TV field is more extensive, because definition, the picture quality of Digital Television are better than traditional simulated television, the development of Digital Television can progressively replace traditional simulated television technology.
Traditional simulated television abbreviates ATV as, existing four kinds of standards such as MAC that are mainly used in NTSC, PAL, the SECAM of ground-wave television broadcast and are used for satellite television broadcasting.The main distinction of four kinds of standards is the processing mode difference of colour signal.The video bandwidth of various standards is basic identical.
Digital television broadcasting is called for short DVB, both can be used for standard definition television broadcasting (SDTV), also can be used for high definition television broadcasting (HDTV).The end of the year 1996, the communication committee member of the United States Federal (FCC) has formulated relevant rules, stipulate that all must adopt digital technology at the HDTV of U.S. television set, but this and do not mean that all digital televisions all must be high definition, also have other possibility simultaneously.
Present simulated television technology is transmitting to the user in the process of TV data, and operator can add ad data etc. as required in TV data.In the simulated television technology, this technology that adds ad data in TV data is generally adopted by the operator of each TV station, and TV user can be watched advertising message in TV reception.
But because the structure of digital television and simulated television is different, and the technology difference of TV data transmission, operator can't be according under the situation of simulated television, exists to adopt identical technology that ad data is joined problem in the digital TV data.

Embodiment
For clearly demonstrating method and apparatus of the present invention, provide preferred embodiment below and be described with reference to the accompanying drawings.
Referring to Fig. 1, Fig. 1 is the flow chart of the embodiment of the invention one, in this embodiment, may further comprise the steps:
Step 101: obtain the content descriptors of digital TV contents data, acquisition time data and channel data in described content descriptors;
Obtain the process of the content descriptors (EIT) of digital TV contents data, can directly obtain by inquiry in the database; Or the digital TV contents data are analyzed obtain.The digital TV contents data here are meant the TV programme of finally playing on television set, content descriptors is also referred to as electronic program guides (EPG) information.
There is several data in the content descriptors, comprises all properties data of related content data, comprise time data in these data, represent the reproduction time of this content-data; Channel data is represented the channel that this content-data is play.Available this time data, channel data from these content descriptors.
Step 102: the time data and the channel data that obtain ad data;
Operator is edit advertisement information in advance, is made into ad data, in ad data, comprises time data, channel data of this ad data etc.Wherein, time data is the time period that this ad data will be play, and channel data is that this advertisement is play on which channel.Also can comprise in the ad data: literal link advertisement, picture do not have link advertisement, picture has link advertisement etc.; If have link in the advertisement, then need to indicate the address of this link and the position that institute's linked contents shows, wherein, the link of advertisement can be linked in the digital TV network that all TVs can have access to.
The order of above-mentioned steps 101 and step 102 also can be put upside down, and does not influence realization of the present invention.
Step 103: judge whether time data and channel data in described ad data and the described content descriptors exist common factor, if exist, then execution in step 104; If there is no, then finish.
For realizing the corresponding of ad data and content-data, can by judging in ad data and the described content descriptors whether have identical time data and channel data, if exist, then explanation need be play this ad data in the process of playing this content-data.Wherein, can there be the situation of the corresponding a plurality of content-datas of ad data possibility, also may has the situation of the corresponding a plurality of ad datas of a content-data.
Step 104: the described ad data that will meet predefine ad data descriptor is incorporated in the described digital TV contents data;
In the process that merges, can merge according to digital video broadcasting information (DVB-SI) standard, ad data will meet predefine ad data descriptor, predefine ad data descriptor also will meet the DVB standard, during merging, ad data is joined in the relevant position in the content-data according to the DVB standard.
Wherein, the descriptor of ad data is defined as follows:
