3. Terms

Electricity cost: The electricity cost of digital TV adapters in 10 years, according to the annual electricity consumption below. The electricity price is set at 0.5 RMB per kWh. Unit: RMB.

Annual electricity consumption: The electricity consumed by the digital TV adapters in one year. The same as TVs’ annual working time and stand-by mode time, digital TV adapters’ annual working time is set at 1080 hours, stand-by mode time is 842 hours. Unit: kWh.

On mode power: The power when digital TV adapters connect to the power supply and provide the main function. Unit: W.

Standby passive mode power: The power of standby passive mode that digital TV adapters connect to the power supply but don’t provide the main function. Digital TV adapters can’t enter this mode until receive an external excitation signal such as remote control. Digital TV adapters can return to on mode by remote control device or internal signal. Unit: W.

Energy efficiency grades: The mandatory grading system for energy using products to disclose the energy performance to the consumers. Grade 3 is the minimum energy efficiency requirement for the market access and grade 1 is the most energy efficient digital TV adapters. The following table shows the energy efficiency requirements in national energy efficiency standard of digital TV adapter.
