Abstract： In order to reduce the usage of the television remote control and realize low power consumption in the standby-awake scenario,，based on the analysis of the consumer electronics control(CEC) 1.4 protocol, the paper proposes an HDMI_CEC standby-awake software scheme by cooperating the CPU and MCU, and implements the detailed functions on the single board described in the scheme. Finally, the actual function was verified by the SL309 instrument. In the verification results, it fully meets the requirements of TV standby-awake. The scheme provides methods and ideas for TV standby wake in low power consumption scenarios.
