Abstract
The invention provides a method, a system and a terminal of a digital television receiving terminal for displaying an advertising message, which are suitable for the technical field of digital televisions. In the invention, a front terminal of a digital television adds advertising service descriptors in a PSI/PI message or a private list, and advertising service data is transmitted by utilizing aTS stream. Then the digital television receiving terminal analyzes out the advertising service descriptors from the PSI/PI message or the private list, analyzes out the advertising service data from the fixed TS stream according to the advertising service descriptors and displays and outputs the advertising message according to the advertising service data. When the content of an advertisement isupdated, the advertising service data and a corresponding advertising service descriptor are edited and modified at the front terminal, and an updating process of the whole embedded software does notneed to be carried, thereby reducing the cost for updating the content of the advertisement and also achieving safer, more reliable and compact updating process of advertisement contents.

Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In an embodiment of the present invention, digital TV front-end is at program specific information/business information (Program Specification Information/Service Information, PSI/SI) add the advertising business descriptor or in the privately owned table, and (Transport Stream, TS) stream transmits advertisement traffic data to utilize transport stream.Receiving terminal for digital television then parses the advertising business descriptor from PSI/SI information or privately owned table, and parses advertisement traffic data according to the advertising business descriptor from TS stream, and according to this advertisement traffic data, shows providing advertisement information.Like this, when upgrading advertisement content, get final product by front-end edit modification advertisement traffic data and corresponding advertising business descriptor, just do not need renewal process to whole embedded software, thereby reduced the cost that ad content upgrades, the process that ad content is upgraded is safer, reliable.
Fig. 1 shows the method implementing procedure of the digital TV front-end advertising information that the embodiment of the invention provides, and details are as follows:
In step S101, in PSI/SI information or privately owned table, add the advertising business descriptor.
Wherein, the advertising business descriptor not only can be used as identifier, has also described network transmission parameter, data encapsulation parameter.The advertising business descriptor mainly comprises frequency and digital television business information, seeks the advertisement traffic data bag for convenience, also comprises the package identification symbol of advertisement traffic data.
In step S102, broadcast this PSI/SI information or privately owned table.
In an embodiment of the present invention, PSI/SI information can for network information table (Network InformationTable, NIT), the server description list (Service Description Table, SDT), Program Map Table (Program MapTable, PMT).Broadcasting PSI/SI information has dual mode, promptly can all broadcast PSI/SI at each frequency of Digital Television, and perhaps, only certain frequency is broadcast PSI/SI therein.
In step S103, broadcast the TS stream that carries advertisement traffic data.
Fig. 2 shows the method implementing procedure of the receiving terminal for digital television display ads information that the embodiment of the invention provides, and details are as follows:
In step S201, receive PSI/SI information or privately owned table.
In an embodiment of the present invention, PSI/SI information can be shown for NIT, SDT shows, pmt table.Front end is broadcast PSI/SI information dual mode, promptly can all broadcast PSI/SI at each frequency of Digital Television, and perhaps, only certain frequency is broadcast PSI/SI therein.According to the mode of broadcasting of front end, receive at current frequency, perhaps, receive PSI/SI information at a certain fixedly frequency (for example EPG frequency).For pmt table, then receive pat table at current frequency earlier, and analyze the table identifier of each professional PMT under the current frequency, thereby receive pmt table by pat table.And,, just can obtain privately owned table by the data flow that receives this table identifier often corresponding to a certain fixed table identifier and physics frequency for privately owned table.
In step S202, in PSI/SI information that judgement receives or the privately owned table whether the advertising business descriptor is arranged.When the advertising business descriptor, execution in step S203, otherwise finish whole flow process.
As embodiments of the invention, the advertising business descriptor may reside in the description circulation of privately owned table, during perhaps, NIT table, the SDT that is present in PSI/SI information shows, the descriptor of pmt table circulates.Judge that for convenience front end all is positioned over the advertising business descriptor in first descriptor circulation at every turn, thereby can whether have the advertising business descriptor to come rapid judgement whether advertising business is arranged by judging in first descriptor circulation.
In step S203,, from the TS data flow, parse advertisement traffic data according to the advertising business descriptor.
When in judging the NIT table, having the advertising business descriptor, then switch to the physical frequencies parameter corresponding physical frequency of advertising business descriptor.At this physics frequency, analyze pat table according to the advertising business descriptor, and find corresponding pmt table, thereby can find the package identification of advertising business correspondence to accord with, thereby can from TS stream, parse advertisement traffic data.
