Abstract
The invention, which mainly relate to the broadcast television program manufacturing and broadcasting fields, provides a caption generator program list synchronous manufacturing method and system based on communication in a protocol way. The method comprises the following steps that: a broadcasting control system generates a program list file and carries out format encapsulation on the program list file according to a protocol format; the broadcasting control system sends the encapsulated program list to a caption generator; the caption generator carries out file parsing according to the protocol format and restores the program list file; and the caption generator generates a caption file according to the program list. In addition, the system consists of a broadcasting control unit, a protocol encapsulation unit, a protocol parsing unit and a caption generator unit. After the broadcasting control unit generates a program list file, the protocol encapsulation unit carries out format encapsulation on the program list file and the encapsulated program list file is sent to a caption generator; the caption generator unit receives the program list file; the protocol parsing unit carries out file parsing; and a caption program list file is manufactured according to the parsed program list file. Therefore, on the one hand, a problem of communication between a broadcasting control system and a caption generator can be solved; on the other hand, because of conversion of protocol formats, compatibility of different system from different factories can be realized, thereby providing a basis for establishment of communication between the playing system and the caption generator.
