Abstract
The invention provides an immediate addressing method of television and securities data, and the method comprises the steps that: a. the data is obtained from a transport stream; b. table ID and table extension ID of the data are obtained from the data; c. that whether the extension ID of the data and stock symbol to be searched for are corresponding to each other is judged, if not, the steps from a to c are repetitively executed, if corresponding, the data is decoded and recording data is obtained on the basis of recording length field of the data. In the addressing method of the invention, the data contains a plurality of mutually independent data projects while a plurality of data projects include at least one news ticker data project. The method can realize the immediate addressing of television and securities data.
Description
Technical field
The present invention relates to the application process of Digital Television, relate in particular to a kind of quick addressing method of TV securities data.
Background technology
Digital Television is universal day by day, application and effect that it can provide a lot of conventional television broadcast modes to realize.In the process that industry is used, need aspect data content, make a breakthrough, for the lifting of whole industry provides widely application foundation and effectively supports.
An example as digital television application, provide quotation information can satisfy the demand of certain customers on the one hand based on Digital Television, further reduce and use threshold, attract the more user who hangs down the operate learning ability to add stock tickers data broadcasting user's ranks, market data instability when another one aspect stock tickers data broadcasting has solved the unavoidable network congestion of the Internet quotation and market and blocks up, untimely problem, and the stability and the fail safe of quotation information transmission risen to high stability and fail safe from low-level the Internet grade television broadcasting grade.But the addressing system of traditional TV securities data and mode classification can not satisfy the needs of this area development.
Summary of the invention
For addressing the above problem, the invention provides a kind of quick addressing method of TV securities data, this method may further comprise the steps: a. obtains data from transport stream; B. from these data, obtain the Table I D and the table Extended ID of these data; C. judge whether above-mentioned table Extended ID is corresponding with the code of the stock that will search for.If not corresponding, then repeat above-mentioned steps a-c.If corresponding, then above-mentioned data decoded, and obtain record data according to the record-length field in these data.In addressing method of the present invention, above-mentioned data comprise separate a plurality of data items, and comprise a ticker information data items at least in these a plurality of data items.
According to an aspect of quick addressing method of TV securities data of the present invention, above-mentioned data items also comprises present quotation data items, timesharing tendency data items and day k line tendency data items.
According to a further aspect in the invention, above-mentioned ticker information data items is to select the information that provides by operator.
In addition, according to a further aspect in the invention, the encapsulation of the form of above-mentioned The data secret section PS.
In addition, according to a further aspect in the invention, above-mentioned record length is the record length of a stock certificate data, and above-mentioned record data comprise the data content of a stock.
In addition, in above-mentioned quick addressing method of TV securities data, after above-mentioned data being decoded and obtain record data, on a television indicator, show described record data by a top box of digital machine according to the record-length field in these data.
But equipment immediate addressing stock certificate datas such as the present invention's set-top box are to be implemented in digital broadcasting and the information issue on the Digital Television.In addition, owing to adopted secret section PS mode to encapsulate the data of being transmitted, accelerated the speed of addressing greatly.
Should be appreciated that the above generality of the present invention is described and the following detailed description all is exemplary and explanat, and be intended to the further explanation that the invention provides for as claimed in claim.
Description of drawings
Comprise that accompanying drawing is for providing the present invention further to be understood, they are included and are constituted the application's a part, and accompanying drawing shows embodiments of the invention, and play the effect of explaining the principle of the invention with this specification.In the accompanying drawing:
Fig. 1 shows flow chart according to one embodiment of the method for the invention.
Fig. 2 shows the example of secret section PS.
Embodiment
Now with embodiments of the present invention will be described by referring to the drawings in detail.Now will be in detail with reference to the preferred embodiments of the present invention, its example is shown in the drawings.In the case of any possible, in institute's drawings attached, will use identical mark to represent same or analogous part.In addition, although employed term is to select from public term among the present invention, but some mentioned terms may be that the applicant selects by his or her judgement in the specification of the present invention, and its detailed meanings illustrates in the relevant portion of the description of this paper.In addition, require not only by employed actual terms, but also will understand the present invention by the meaning that each term contained.
Fig. 1 shows an embodiment of quick addressing method of TV securities data of the present invention.As shown in Figure 1, at first, read information on services (ServiceInformation), obtain a Table I D (TableID) and a bag ID (PacketID) (step 101); Subsequently, the data (step 102) that acquisition is transmitted from the transport stream TS (Transport Stream) that transmits by network; Further from this extracting data Table I D and table Extended ID (TableIDExtention) (step 103); Subsequently, the code of judging above-mentioned table Extended ID and the stock that will search for whether corresponding (step 104).If not corresponding, then repeat above-mentioned steps 102 to step 104.If corresponding, then the data of this acquisition are decoded, extract a record length (RecordLength) field and obtain record data (RecordData).
About above-mentioned data, need classify for realizing immediate addressing.According to an embodiment, data are divided into four data projects: present quotation data, timesharing tendency data, day k line tendency data and ticker information.Wherein be data mode well known in the prior art, it can be provided separately or directly obtained from relevant Internet resources by operator.And the information that ticker information is wherein preferably provided by operator's selection.This sends platform for operator provides independent data.Above-mentioned four data projects are independent of each other.
Below provide a code example of above-mentioned data items:
Definition 0xFFFF is index and horse race lamp, 0x0000～0xFFFE is PageID (page or leaf ID), the PageID scope is that 0x000～0xFFF PageID definition has two kinds of situations: be directed to personal share: it is one page that n props up stock, and the counting of each page is PageID, and N can be a natural integer;
RecordList()
{
8 of numRecords (1 byte);
for(n＝0；n＜numRecords；n++)
{
16 of RecordLength (2 byte);
for(m＝0；m＜RecordLength；m++)
8 of RecordData (1 byte);
}
}
Wherein:
NumRecords: the stock number of this private section carrying;
RecordLength: the data record size that is a stock;
RecordData: be a stock certificate data content.
Example: have for one group of real time data:
RecordList
{
numRecords：3；
{//LineID＝0
RecordLength：330.
RecordData: " 000001 Index of Shanghai Stock Exchange 00001093.702...... "
}
{//LineID＝1
RecordLength：330.
RecordData: " 000002 A-share index 00001148.595...... "
}
{//LineID＝2
RecordLength：330.
RecordData: " 000003 B share index 00000065.733...... "
}
}
For present quotation, the timesharing tendency, K line tendency, its form of horse race lamp is as follows respectively:
