1. A remote control toy car wirelessly communicable with a client terminal and configured to support wireless real-time transmission of audio and video signals, the toy car comprising a microprocessor, a clock generation circuit, a program memory, a random access memory, a power conversion circuit, a power supply module, a video capturing circuit, a radio transceiving circuit and an audio circuit, wherein:

  • the microprocessor, coupled to the clock generation circuit, the program memory, the random access memory, the power conversion circuit, the video capturing circuit, the radio transceiving circuit and the audio circuit, is configured to execute one or more processes comprising;

    after power-up initialization of the microprocessor, activating the video capturing circuit and the audio circuit;

    according to instructions stored in the program memory, obtaining captured video data from the video capturing circuit and captured audio data from the audio circuit, followed by further processing, compressing and packetizing the captured video data and the captured audio data to yield first video data packets and first audio data packets, and storing the first video data packets and the first audio data packets in the random access memory;

    when the microprocessor receives via the radio transceiving circuit a request signal issued from the client terminal, retrieving the first video data packets and the first audio data packets from the random access memory according to the instructions stored in the program memory, and forwarding the first video data packets and the first audio data packets to the client terminal through the radio transceiving circuit, thereby allowing the client terminal to display images and generate audio sound in a real-time manner according to the first video data packets and the first audio data packets; and

    when the microprocessor receives via the radio transceiving circuit second audio data packets wirelessly sent from the client terminal, forwarding the second audio data packets to the audio circuit for processing in order to produce an audio output via a speaker;

    the clock generation circuit is configured to provide one or more clock signals required by the microprocessor;

    the power conversion circuit is used for providing power to the microprocessors and devices coupled thereto; and

    the power supply module, coupled to the power conversion circuit, is used for providing power to the power conversion circuit.
