Abstract: The present disclosure provides a video encoding circuit and a wireless video transmission apparatus and method. The wireless video transmission apparatus includes a wireless transmitter circuit and a video encoding circuit. The wireless transmitter circuit is configured to transmit a video stream with a bit rate to a wireless transmission channel and provide a transmission state message according to a transmission state of the wireless transmission channel. The video encoding circuit is coupled to the wireless transmitter circuit to receive the transmission state message. The video encoding circuit is configured to perform an encoding operation on video data to generate the video stream to the wireless transmitter circuit and dynamically adjust the bit rate of the video stream delivered to the wireless transmitter circuit according to the transmission state message.
