Problems solved by technology
[0003] After the implementation of the standard, many flat-panel TV energy-efficiency test equipment have appeared one after another, but most of them only have TS stream output, or only component output, composite video output, and analog audio output.
However, usually multiple solutions are required on the market at the same time, which may require the purchase of different equipment, resulting in increased investment costs and a lot of inconvenience to the testing work

The invention relates to an energy efficiency testing signal generating device of a flat panel television. The device comprises a transport stream (TS) output device and a decoding deck device, wherein the decoding deck device is in communication with the TS output device and used for receiving command signals transported by the TS output device, and the decoding deck device controls output of analog signals which are identical to those output by the TS output device and synchronous with the TS output device so as to perform energy efficiency testing of the flat panel television. The signal generating device is simple, easy to operate, and capable of combining TS output and decoding deck output, simultaneously achieving digital asynchronous serial stream output, digital synchronous parallel stream output, component output, composite video output and audio left-right sound track output, and achieving energy efficiency testing of the flat panel television under the condition that low costs are input.
Description
technical field [0001] The invention relates to a signal generating device for testing the energy efficiency of a flat panel TV. Background technique [0002] Against the backdrop of the rapid development of the flat-panel TV industry, the national mandatory standard GB 24850-2010 "Limitable Values of Energy Efficiency and Energy Efficiency Levels of Flat-panel TVs" was formulated and released on June 30, 2010, and officially launched on December 1, 2010. implement. The formulation of the national standard "Flat Panel TV Energy Efficiency Limits and Energy Efficiency Grades" provides a scientific basis for the implementation of the "Energy Conservation Law of the People's Republic of China" in the flat panel TV industry. In addition to limiting the passive standby power of flat-panel TVs, this standard also divides the energy efficiency levels of flat-panel TVs. Among them, Level 1 has the highest energy efficiency and is the most efficient product; Level 2 is the energy...
