1. An audio transmitting method, comprising:
transmitting, by a smart television, a first system time data packet to a control apparatus, wherein the first system time data packet comprises first system time of the smart television at which the smart television transmits the first system time data packet to the control apparatus;
receiving, by the smart television, a command for audio data transmission transmitted from the control apparatus; and
transmitting, by the smart television, an audio data to the control apparatus in response to the command for audio data transmission, wherein the audio data comprises second system time of the smart television at which the smart television transmits the audio data, such that the control apparatus calculates a network delay of transmission of the audio data between the smart television and the control apparatus according to the first system time and the second system time and determines whether to play the audio data according to the network delay;
wherein before the transmitting, by the smart television, the audio data to the control apparatus, the method further comprises:
determining, by the smart television, whether the audio data is invalid audio data by performing cyclic detection on a first byte and a last byte of a frame of the audio data;
in response to a byte of the frame of the audio data being not a preset character, determining the frame of the audio data as valid audio data;
in response to each byte of the frame of the audio data being the preset character, determining the frame of the audio data as invalid audio data;
in response to the audio data being invalid audio data, adding, by the smart television, indication information for indicating invalid audio data into the audio data, and compressing, by the smart television, the audio data with the indication information to generate an invalid audio data packet; and
in response to the audio data being valid audio data, determining, by the smart television, to transmit the valid audio data to the control apparatus.
