Abstract
The invention provides a method for a set top box to obtain a DSM-CC application program rapidly. The method comprises the following steps: after the set top box is powered on, utilizing MessageIDs of DSI, DII and DDB messages respectively to simultaneously capture and keep DSI data, DII data and DDB data in an TS flow; receiving a DSM-CC application request sent by a user; analyzing the DSI data and obtaining specific downloading position information of a file or directory; utilizing the downloading position information and obtaining corresponding DII data from the set top box; analyzing the DII data and obtaining specific module information; utilizing the specific module information and obtaining the DDB data from the internal storage of the set top box; analyzing the DDB data, and traversing to find and keep the required files or directory structures; and obtaining a full file and directory structure, and obtaining the whole relevant DSM-CC application. According to the method and device for the set top box to obtain the DSM-CC application program, the blocking, pause and waiting cases do not occur when the user is operating the DSM-CC application program.
Description
Technical field
The present invention relates to set-top box technique field, especially a kind of method and apparatus of Set Top Box quick obtaining DSM-CC application program.
Background technology
DSM-CC OC (object carousel) makes to utilize directory object, file object and flow object, and the structurized group's of the object from broadcasting server to broadcast reception end (client) transmission becomes easy.Actual catalogue and content (object realization) are all positioned on this server.This server constantly relevant object is inserted into use object carousel agreement, Digital Television is mutually in the middle of compatible TS stream.Object carousel is a part for digital television business.The content that the catalogue of transmission and file object comprise object, and the flow object of transmission is the reference data of other stream in broadcast.This flow object may be included in the information about DSM-CC event of broadcasting in a specific stream.DSM-CC event can be broadcasted by general flow data, and can be used for triggering DSM-CC application.
But the crawl of data in broadcast reception end (client) (directory object, file object and flow object), resolving and processing is a very complicated process, traditional order captures data and analysis mode, can cause Set Top Box to obtain the efficiency of DSM-CC application not good, thereby affect the time that client obtains DSM-CC application, experience not good.
Concrete, when traditional digital receiver obtains DSM-CC application in realization, often when DSM-CC application starts demand file, what just start order captures DSI from TS stream, DII, the data such as DDB, after the whole crawls of related data are complete, carry out again resolution data work, traversal locating file and catalogue.If DSM-CC application is to consist of a large amount of files and catalogue, the speed that can cause relevant DSM-CC application to be obtained slows down greatly, and user also can have a greatly reduced quality to the Experience Degree of product, is unfavorable for like this popularization and the sale of product.Object of the present invention be exactly for facilitate user can be in Set Top Box rapidly and efficiently get DSM-CC application, improve the competitiveness of Set Top Box manufacturer.
Summary of the invention
In view of this, be necessary for the deficiencies in the prior art, a kind of method and apparatus of Set Top Box quick obtaining DSM-CC application program is provided.
The object that the present invention is is achieved through the following technical solutions:
A method for Set Top Box quick obtaining DSM-CC application program, it comprises the following steps:
S1, after set-top-box opening, utilize the ID of Message separately of DSI, DII and DDB message to capture DSI data, DII data and the DDB data in TS stream simultaneously, and be saved to internal memory;

S3, analyze the DSI data grab, obtain the concrete download location information of this document or catalogue;
S4, utilize described download location information, from Set Top Box internal memory, obtain corresponding DII data;
The DII data that S5, analysis grab, obtain concrete module information;
S6, utilize described concrete module information, from Set Top Box internal memory, obtain the DDB data that obtain in S1;
The DDB data that S7, analysis S6 obtain, file or the bibliographic structure that will look for found and preserved to traversal;
S8, obtain file and bibliographic structure completely, get whole relevant DSM-CC application.
In described S5, described concrete module information, comprises addressing and the locating information of module.
After described S7, also comprise: judge whether to find and be saved in all files, as judgment result is that, be, enter S8; As the determination result is NO, get back to S4.
It is a kind of for realizing the device of said method that the present invention also provides, and it comprises:
Data capture module, it utilizes the ID of Message separately of DSI, DII and DDB message to capture DSI data, DII data and the DDB data in TS stream simultaneously, and is saved to internal memory for after set-top-box opening;
Receiver module, the DSM-CC application request that it sends for receiving user;
The first analysis module, it obtains the concrete download location information of this document or catalogue for analyzing the DSI data that grab;
The first acquisition module, it,, for utilizing described download location information, obtains corresponding DII information from Set Top Box internal memory;
The second analysis module, it,, for analyzing the DII data that grab, obtains concrete module information;
The second acquisition module, it obtains described data capture module and is stored in the DDB data in Set Top Box internal memory for utilizing described concrete module information from Set Top Box internal memory;
The 3rd analysis module, the DDB data that it gets for analyzing described the second acquisition module, file or the bibliographic structure that will look for found and preserved to traversal;
Application acquisition module, it gets whole relevant DSM-CC application for obtaining file and bibliographic structure completely.
The DII data that described the second analysis module analysis grabs, the concrete module information obtaining comprises addressing and the locating information of module.
The device of described Set Top Box quick obtaining DSM-CC application program, also comprise program file judge module, it is for analyzing at described the 3rd analysis module the DDB data that described the second acquisition module gets, traversal is found and is preserved after the file or bibliographic structure that will look for, judges whether to find and be saved in all files.
Described data capture module, specifically comprises:
