Method and device for reading document of data broadcast system

Abstract

The invention relates to a method of reading document by the data broadcast system and its system for providing the digital TV broadcast service more quickly. The data broadcast document reading device with said invention stores the all documents extracted from the target band carrier into the stacked memory of JVM, and when the application program refers the application of transferring document, moving the pointer of relative document directly to the stacked memory of JVM, then executing relative document. Since avoiding searching for the document relative to the transferred document of application program from the target band carrier, but directly searching and transmitting in the JVM, so the speed of reading document is quick. In addition, the invention can significantly reduce the extra consumption coursed by searching for the relative document in the target band carrier when transferring the needed document of application program each time with present technique.

Description

technical field [0001] The present invention relates to data broadcasting systems. Specifically, the present invention relates to a method and device for rapidly reading files from data broadcasting. Background technique [0002] Generally speaking, a data broadcasting system consists of a radio and television bureau, a set-top box (set-top box) and a television set. The set-top box extracts files from the broadcast data stream provided by the radio and television bureau and plays them on the television. [0003] Here, the above-mentioned set-top box may also be set in a television. [0004] Digital broadcasting provides video and audio output with higher image quality and higher sound quality than previous analog broadcasting, and also provides various convenient functions such as data broadcasting and interactive communication. [0005] The digital broadcast protocol used in DVB-MHP basically supports all service providers and object carousel (OC: object carousel). The ...

Problems solved by technology

[0015] However, as mentioned above, the existing method of reading files must be called to the target carousel via the JVM whenever the application needs a file. The target carousel must analyze each module as an object every time. have to be transferred to the application via the JVM

Therefore, whenever the application program makes an application call, the target conveyor belt must search for the file to provide, which has considerable additional overhead, and there are also problems such as increasing the reading time

At the same time, this process of searching for files continues, and there are problems such as significantly reducing the running speed of the application program.
