Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] figure 1 It is a flow chart of the set-top box demultiplexer stress testing method in an embodiment, such as figure 1 As shown, the method includes the following steps:

[0032] S10: Define a global enable flag in the main thread, and set the data tables to be filtered, the PID of each data table, and the number of times each filter table PID needs to be filtered, and set the global enable flag to 1 when starting the test.

[0033] In order to enable the main thread to control the stress test, a global enable flag is defined in the main thread in this embodiment to control the start and en...

Abstract

The present invention relates to a set top box demultiplexer (demux) pressure testing method, system, and testing device. The method comprises: defining a global enable flag in a main thread, and configuring data tables to be filtered, a PID of each data table, and the number of times a PID of each filter table needs to be filtered; defining a group of global array variable tags in sub-threads so as to record the number of times the PID of each data table is filtered, the data table passing a pressure test if the number of times each data table PID is filtered satisfies a set range in comparison with the number of times the filter table needs to be filtered; the main thread detecting, according to a set cycle period, the number of times each data table PID in the sub-threads is filtered; and when the main thread detects that all of the data tables pass the stress test, immediately setting the global enable flag to 0 from 1, determining that the demux stress test has been passed, and ending the test. In this way, a test can be ended after the test has been passed, without waiting a fixed length of time, and the test result is accurate and highly credible, greatly satisfying testing requirements.

Description

technical field [0001] The invention relates to the field of digital television, in particular to a set-top box demultiplexer (demux) stress test method and system. Background technique [0002] During the production process of the set-top box, it is necessary to carry out a stress test on the demux (demultiplexer). The demultiplexer stress test currently uses the following methods to filter the data table: [0003] Set the main thread and sub-thread, set the data table to be filtered, the data table PID (process identifier) ​​and the number of times to be filtered in the main thread, and set the filter flag (filter.Enable) to 1, and then wait in the main thread Fixed duration (long enough, such as 5s, 30s, etc.), after the fixed duration is reached, set the filter flag (filter.Enable) to 0, that is, terminate the filtering of the data table. [0004] Define a global variable flag (pass_flag) in the child thread. During the waiting process of the main thread, if the demult...
