Embodiments of the present invention disclose systems and methods for providing enhanced features using an ATC Overlay data link. The audio data does not need to undergo an operation of audio coding and decoding every time when the audio data passes through a control server, and the coding and decoding operations performed by the control server are reduced drastically. The subject movement is analyzed relative to the determined magnitude, direction of subject movement, and the current framing, to determine that the subject is properly framed by the current shot framing or whether modifications of the current shot framing are required to capture the moving subject, or to determine a new shot selection and new shot framing. The first mobile communication apparatus is in a standby period under an idle mode according to a wireless communication protocol; the second mobile communication apparatus is in an active period under the idle mode according to the wireless communication protocol and establishes a communication link with the control apparatus.
