1. A method for audio and video control response and bandwidth adaptation based on network streaming applications, comprising:

  • transmitting a control command received by a stream communicator of the server to a stream controller of the server;

    the player can either discover the expiration of the buffered streaming data by itself and empty its buffer or flush the expired buffered data notified with the buffer expiration message sent by the communicator of the server;

    enabling the stream controller to control an input source of a video/audio capturer;

    estimating whether the amount of streaming data stored in the buffer is within a safe range;

    delivering the estimation result and bandwidth variation information detected by the server to a stream adaptor;

    determining whether the amount of the stream data stored in the buffer is less than a threshold value; and

    enabling the stream adaptor to adjust a timestamp scalar according to the estimation result and the bandwidth variation information if the amount of the stream data is less than the threshold value, thereby adjusting a consumption rate of the streaming data buffered in the player for re-accumulating streaming data of the buffer.
