Digital television field environment simulation method, terminal and computer readable medium

Abstract

The embodiment of the invention discloses a digital television field environment simulation method, a terminal and a computer readable medium. The method comprises the steps as follows: after startingup, a test terminal automatically records test process information which comprises a software database, code stream information of each frequency point and an operational process; and the test terminal generates a storage command when recognizing a running problem, and stores the test process information according to the storage command to form a test storage file which is used for transmitting back to a playback terminal and thus allowing the playback terminal to simulate a test field environment. According to the digital television field environment simulation method, terminal and computerreadable medium provided by the embodiment of the invention, the digital television field environment is simulated, the problem in field is accurately reproduced, the product development cost is reduced, and the product development efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to digital television technology, and in particular to a method for simulating a digital television field environment, a terminal, and a computer-readable medium. Background technique [0002] The digital TV system is an end-to-end system that processes signals digitally from program acquisition, program production, program transmission to the user end. Because the programs broadcast in different regions of different countries and different regions of the same country are different, the digital TV signals transmitted in each region are different, that is, the digital TV environment in each region is different and cannot be copied. [0003] At present, three schemes are usually used for digital TV terminal product development, specifically: first, send a large number of project technicians to different sites in various regions for product development and debugging; second, send a small number of testers to dif...

Problems solved by technology

[0004] In the first solution, a large number of project technicians are dispatched to the site for R&D and debugging, which greatly increases the cost of product development

In the second solution, the disadvantages of recording code streams are: first, the equipment for recording code streams is relatively expensive, and there is no guarantee that every project has the conditions to record code stream operations; second, the code stream files are very large, resulting in storage Difficult and extremely slow transmission, a few minutes of code stream sometimes takes a day to transmit, so usually only record the problem code stream when there is a running problem during the test process, but due to the sporadic nature of running problems, the recorded code stream cannot completely contain the problem The code stream cannot be reproduced by playing the recorded code stream; third, because of the configuration of the recording code stream device and the limitation of the code stream file storage and transmission, usually only one frequency point of the code stream is recorded, so at some switching frequency points The operation problems that appear in the system cannot be reproduced; fourth, the equipment for playing the code stream is relatively expensive, and usually cannot support multiple people to play the code stream at the same time, so that the operation problems can be reproduced; When the process is communicated, misunderstandings often occur, which reduces the efficiency of product development

In the third solution, the disadvantage of recording the video of the problem phenomenon is that usually only experienced technicians can guess the product problem by watching the video of the problem phenomenon, and after product debugging, it is impossible to test the product problem that has been fixed, which also reduces product development. efficiency
