Embodiment Construction

[0019] The generation method of the set-top box upgrade code stream of the present invention comprises steps:

[0020] a. In the file format of the descriptor of the set-top box upgrade code stream, the content of the descriptor is divided into conditions and fields, where the conditions include: conditional statement, conditional start character and conditional end character; the attributes of the field include: the associated file of this field Name, the associated field name of this field and the functional interface function of this field; and arrange the priority order of all description sub-files.

[0021] In the file format of the descriptor of the upgrade stream, each line is marked with a condition, a condition end character or a field; if the mark is a condition, the attributes of the line include a condition statement and a condition start character; if the mark If it is a conditional terminator, the row includes the attribute at the end of the latest conditional ra...

Abstract

The invention relates to a method for generating upgrade code streams of a set-top box. The method comprises the following steps of: a, dividing a descriptor into a condition and a field in a file format of the descriptor of an upgrade stream, wherein the condition comprises condition statements, a condition start mark and a condition end mark, and the attribute of the field comprises a relevant file name of the field, a relevant field name of the field and a functional interface function of the field; b, generating descriptor files according to the file format of the descriptor; generating an implementation function of each field interface function; and d, resolving each descriptor file to generate a data model, and running the implementation function according to the interface function in each resolved descriptor file so as to generate an upgrade code stream file packet. The method for generating the upgrade code streams of the set-top box can be compatible with various upgrade specifications, and by using the method, the problem of numerous generating tools of the upgrade code streams in the prior art is solved, the development cost is reduced, and the development and development tools of the upgrade code streams of the set-top box are unified and standardized.

Description

technical field [0001] The invention relates to a method for generating an upgrade code stream of a set-top box. Background technique [0002] With the development of the global digital TV industry, the digital TV set-top box has been popularized in every family and has become a household necessity. Accompanied by it, many digital TV operators have been born in the world. These operators have established their own operator specifications because of their different regions or different development concepts. With the development of digital TV, these specifications are also applied in a wider and wider range, and one of the specifications is the software upgrade specification of digital TV set-top boxes. The set-top boxes produced by digital TV set-top box manufacturers must meet the requirements of these upgrade specifications, and the set-top box manufacturers need to provide operators with upgrade code streams that meet the upgrade specifications, which are used to upgrade ...
