Description
Technical field
The present invention relates to set-top box technique field, especially a kind of method of set top box quick obtaining DSM-CC application programs
And device.
Background technology
DSM-CC OC (object carousel) cause using directory object, file object and flow object, from broadcasting server to
The transmission of the group of the structuring of the object at broadcast reception end (client) becomes easy.Actual catalogue and content (object implementatio8)
It is all located on the server.Related object is constantly inserted into using object carousel agreement, DTV by the server
Mutually in the middle of compatible TS streams.Object carousel is a part for digital television business.The catalogue and file object of transmission comprising pair
The content of elephant, and the flow object transmitted is the reference data of other streams in the broadcast.The flow object be possibly comprised in one it is specific
The information on DSM-CC events broadcasted in stream.DSM-CC events can be broadcasted by general flow data, and can be used
To trigger DSM-CC applications.
But in broadcast reception end (client) data (directory object, file object and flow object) crawl, parsing
And processing is a very complicated process, traditional order crawl data and analysis mode can cause set top box to obtain
The efficiency of DSM-CC applications is not good, so as to influence client to obtain the time of DSM-CC applications, experiences not good.
Specifically, traditional digital receiver is when realizing that obtaining DSM-CC applies, often when DSM-CC applications start
When demand file, just start order captures DSI from TS streams, DII, the data such as DDB, when related data has all been captured
Bi Yihou, then carry out parsing datamation, traversal locating file and catalogue.If DSM-CC applications be by substantial amounts of file and
Catalogue is constituted, then the speed that related DSM-CC applications are obtained can be caused to slow down significantly, user can be also beaten greatly the Experience Degree of product
Discount, is so unfavorable for the popularization and sale of product.The purpose of the present invention is exactly that user can be fast on the set-top box for convenience
The fast efficient DSM-CC that gets is applied, and improves the competitiveness of set top box manufacturer.
The content of the invention
In view of this, it is necessary to which there is provided a kind of set top box quick obtaining DSM-CC application journeys in view of the shortcomings of the prior art
The method and apparatus of sequence.
The purpose that the present invention is is achieved through the following technical solutions：
A kind of method of set top box quick obtaining DSM-CC application programs, it comprises the following steps：
