STB Auto Test 

    In order to guarantee the reliability of IPTV service, every upgrade of set-top box and revision of EPG requires a test of service availability, which is a simple and repeated but huge work and consumes a lot of time and energy of operation and maintenance units。

   Systen Architecture: three-tier architectures—Hardware acquisition、service acquisition、Context of Use
   The video content screen is directly obtained from THE HDMI output of the STB by using a real STB, and the infrared control of the STB is carried out by simulating the actual operation of the user, so as to completely restore the user's real experience and realize the test of the set-top box boot/live broadcast/on-demand /EPG.

   Basic Principle—The Principle of Itest’s STB Auto Test is completely similar to that of manual testing
   The test process is shown in figure.The test environment consists of TV, remote control, STB and home gateway.The TV and the STB are connected with a video line and an audio line, and the connection between the STB and the home gateway is an Internet line. The testers conduct regression tests through the remote control operation.

  Core Competence------Automatic dialing and testing is carried out through remote control script. The script is formulated once and is effective for a long time
 

    Automatic test setting and result output: automatic test setting is carried out through script of remote control, and the script is formulated once, which is effective for a long time.Automatic output of test results to avoid human factors

   Context of Use—It can be used for STB version testing, delivery sampling testing, upgrade verification, long stability testing and other scenarios
   delivery sampling testing:Improve the terminal arrival test efficiency of branch company, and liberate the testing personnel of branch company
   upgrade verification:Solve the problem of cutover in the early morning for first-line operation and maintenance personnel, and reduce the pressure of first-line operation and maintenance.
   long stability testing:Improve the testing efficiency of STB stability.

   System UI—STB Auto Test UI

    Remote control: the platform can be remotely controlled by infrared
    Test scenario: Test all the built-in scripts in the scenario
    Scheme scheduling: Support multiple set-top boxes to issue tasks simultaneously
    Function verification track: Supports multiple set-top boxes to issue tasks simultaneously
    Test results: Test scenario data is summarized in one table
    Statistics: statistics of all cities and set-top box pass rate ranking
