Embodiment
Purpose of the present invention aims to provide a kind of application data retrieving method of set-top box, utilize this method can realize that download and application to the application data of set-top box, user can be selected to expand or the function of upgrading set top box, enriched the application of set-top box, realize the differentiation of set-top box, personalization; Simultaneously, by the realization of selected down load application is provided to the user, also provide the development opportunity of developing new business at particular group for operator.
Please refer to shown in Figure 1, the schematic flow sheet of a preferred embodiment of the application data retrieving method of the set-top box that discloses for the present invention.Present embodiment comprises the steps:
Step s110: the user sets the application data that set-top box need be obtained;
Wherein, preserve the application data tabulation of the tie point that comprises some application datas in the set-top box, and set-top box provides the user to select the selection interface of tie point in the application data tabulation.The user sets the application data that need obtain by following manner:
The one, the user selects the tie point of the required application data correspondence of obtaining from described application data tabulation, such as, select personalized start-up picture, recreation and other application programs etc.;
Another is that the user is provided with the condition that the tie point of application data correspondence in the tabulation of described application data upgrades, and that is to say that the user selects the partial function of set-top box software is upgraded or expanded.
Step s120: according to user's selection, (NetworkInformation Table NIT), finds the frequency point information of described application data to set-top box at dominant frequency point search network information table;
Owing in digital television signal, utilize multiplex technique to make the corresponding multi-channel program of one road code stream.Simultaneously, a physical channel can only provide the road transport stream that comprises multi-channel program.Therefore, watch a certain road program wherein, also must (Transport Stream proposes the compressed package of this road program in TS), and then decodes from transport stream.As for how from numerous transport stream, choose one tunnel playing programs, in the transport stream (Transport Stream) of mpeg-2, program specific information PSI (Program SpecificInformation) is exactly how the heterogeneity of different programs of regulation and program is multiplexed into a unified code stream.With PSI is the formation that the basis can provide a code stream, thereby helps the user that program is selected.
Therefore, in this step, NIT provides some relevant information of multiple path transmission flow, physical network and Network Transmission, as be used for the information of parameter aspects such as tuning frequency information and coded system, modulation system, be used for identification, to find the frequency that can obtain described application data to multiple path transmission flow.
Behind the frequency that step s130: lock step s120 searches, at this frequency search program aid table (Program Association Table, PAT), find the described application data that can obtain in the current information stream Program Map Table (Program Map Table, PMT);
Wherein, in PAT, comprise be exactly with the packet identifier of the transmission bag at the corresponding pmt table of program transport streams place, every road (Packet Identifier, PID) information is by to its decoding, just can decipher single program transmission stream, also be the core place that PID changes, the transmission that transmits PAT is surrounded by its unique PID number, and any other bit stream must not re-use this number, again other is transmitted the information multiple connection at last and get up, form the part of a system-level transmission stream.
Step s140: resolve described Program Map Table (PMT), obtain the packet identifier (PID) of the packet of forming described application data;
Wherein, the PID of pmt table is provided by PAT and provides.Can obtain the information that comprises in one road program by pmt table, for example: this road program constitutes type (video, audio frequency, data) with these streams, the PID that each mobility is answered in the appointed program etc. by which stream.
Step s150: by resolving described Program Map Table (PMT), obtain the version information of described application data, and the version information of the application number of preserving with set-top box compares,, then continue next step if the former is the application data of redaction;
When this step is especially upgraded to the software function of set-top box at user's selection, judge upgraded version information, allow the user select the user-centered interface of whether upgrading.
More preferably, in the above-mentioned steps,, and provide the user to select whether to upgrade described application data,, then continue next step if the user selects to upgrade described application data with the comparative result prompting user of version information.
Step s160:, obtain corresponding packet according to described packet identifier;
Step s170: judge whether to finish and obtain described packet, if the data packet group of obtaining is synthesized described application data.
For digital television signal, at first need audio signal, vision signal and data-signal carry out ES (Elementary Stream) coding, in MPEG-2, be encoded into PES (PacketizedElementary Stream) bag, and then the PES bag converted to the transmission bag TP of certain-length.
Therefore, among the above-mentioned steps s170, set-top box is according to the descriptor of PES, and the packet combination with obtaining is reduced to described application data.
More preferably, in the above-mentioned steps, also comprise: described application data parity check; And preserve described application data.
Correspondingly, the present invention also discloses a kind of application data deriving means of set-top box.Please refer to shown in Figure 2ly, this device can be the separate unit in the set-top box, be used to provide the application data that the user selects to download after, the needed application data of download user from the network.This device 200 specifically comprises:
User's setting module 210 provides the user to set the application data that set-top box need be obtained;
Search module 220, be connected with described user's setting module 210, at dominant frequency point search network information table (NIT), find the frequency point information of described application data, and, find the Program Map Table (PMT) of the described application data that can obtain in the current information stream in this frequency search program aid table (PAT);
Parsing module 230 is connected with described search module 220, resolves described Program Map Table, obtains the packet identifier (PID) of the packet of forming described application data;
Version comparison module 240 by resolving described Program Map Table, obtains the version information of described application data, and the version information of the application number of preserving with set-top box is compared; If the former is the application data of redaction, then obtain described application data by described application data acquisition module.
Application data acquisition module 250 obtains corresponding packet according to described packet identifier, and according to the descriptor of PES, with the synthetic described application data of the data packet group of obtaining.
More preferably, device of the present invention also can comprise:
The parity check module is done parity check to the described application data of being obtained by described application data acquisition module; Memory module connects with application data acquisition module lotus root, preserves described application data.
To sum up, the present invention has following useful technique effect owing to adopted as above technical scheme:
1, the present invention can realize machine is pushed up by the function of user selection expansion or upgrading set top box is provided The application of STB has been enriched in the download of the application data of box and application, the differentiation of realization STB, Personalized;
2, simultaneously, the present invention also is operator by the realization of selected application data-downloading is provided to the user Development opportunity for particular group exploitation new business is provided.
