Method and system for field simulation test of digital TV

Abstract

The invention relates to the technical field of digital televisions, and particularly relates to a simulation test method and a system for the digital television field. The method comprises the steps of receiving a field simulation test request from a client, wherein the field simulation test request comprises the to-be-tested area information; judging whether the code stream information of the to-be-tested area is stored in a server or not; if not, sending a collection instruction to code stream collection equipment in the to-be-tested area and controlling the code stream collection equipment to collect the code stream information of the to-be-tested area; receiving the code stream information collected by the code stream collection equipment and sending the code stream information to the client to enable the client to conduct the field simulation test. According to the invention, the code stream collection equipment in each area can be remotely controlled, and the real-time code stream information is acquired. Meanwhile, the field simulation test on digital televisions at different places is enabled, and the simulation test efficiency of digital televisions is improved.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a digital television on-site simulation test method and system. Background technique [0002] In order to ensure the reliability of the machine, most TV manufacturers will do the overall performance test before mass production. Other functions can generally be simulated and tested at the design location. For DTV (Digital TV, digital TV), due to various countries, Various regions, as well as different provinces and cities in the same country will also broadcast different programs, which makes the test of digital TV more troublesome; one way to test digital TV is to play the pre-recorded code stream through the code stream instrument, and output the digital TV The signal is re-connected to the TV for testing; the other is to go to the site and directly connect the antenna with digital signals to the digital TV for functional testing. This method can better reflect the pe...

[0002] In order to ensure the reliability of the machine, most TV manufacturers will do the overall performance test before mass production. Other functions can generally be simulated and tested at the design location. For DTV (Digital TV, digital TV), due to various countries, Various regions, as well as different provinces and cities in the same country will also broadcast different programs, which makes the test of digital TV more troublesome; one way to test digital TV is to play the pre-recorded code stream through the code stream instrument, and output the digital TV The signal is re-connected to the TV for testing; the other is to go to the site and directly connect the antenna with digital signals to the digital TV for functional testing. This method can better reflect the performance of the TV in real time, but because relevant personnel need to be sent to the site, usually It would be a waste of time and manpower

[0003] For the products that have been sold, there may also be some after-sales problems. Due to the different code streams in different regions, and even the code streams in some regions are non-standard signals, it will cause some serious bugs in the TV. At this time, engineers need to be sent to analyze on site. Processing or recording problematic code streams for analysis requires high labor costs
