Method and device for modifying code stream file data for set-top box testing

Abstract

The invention provides a method for modifying data of code stream files used for set-top box testing. The method comprises the following steps: converting the original code stream files into section data structures: parsing the data packets of the original code stream files into a plurality of data tables, each Each of the data tables is converted into a section data structure and put into the corresponding global section data structure of the data table, wherein the data table that needs to be modified is defined as a target data table; the section data of the target data table The modification of the data content of the structure is a new section data structure; the generation of the new code stream file: the new section data structure is converted into a new data packet, and the new data packet is written into the data packet according to the sending interval of the target data table Describe the original code stream file to generate a new code stream file. The invention also provides a data modifying device for code stream files used for set-top box testing. Compared with related technologies, the method and device for modifying data of code stream files used for set-top box testing in the present invention have high testing efficiency and good accuracy.

Description

【Technical field】 [0001] The invention relates to the technical field of set-top box testing, in particular to a method and device for modifying data of code stream files used for set-top box testing. 【Background technique】 [0002] At present, in order to provide customized services to customers at the front end of an operator's digital TV network, set-top box designers are required to test these services of the set-top box when providing software that meets the requirements for the operator. During the test of the set-top box, multiple test items need to play code stream files for testing. [0003] However, some test items cannot be verified due to the limitation of the actual stream file, for example, the channel name is too long, the program name is too long, etc.; some test items are limited by the actual transmitted stream file, which will lead to low test efficiency and long test time , such as booking programs, etc. [0004] In related technologies, although a priv...

Problems solved by technology

[0003] However, some test items cannot be verified due to the limitation of the actual stream file, for example, the channel name is too long, the program name is too long, etc.; some test items are limited by the actual transmitted stream file, which will lead to low test efficiency and long test time , such as booking programs, etc.

[0004] In the related technology, although a private table can be inserted into the code stream file during the set-top box test, the existing data table in the code stream file cannot be changed, which seriously affects the test efficiency
