The invention discloses an energy control system of video transmission in a hybrid wireless environment, pertaining to the technical field of video transmission control. The system of the invention comprises a sender and a receiver. The receiver receives video stream data, generates channel feedback information according to the received video stream data and then sends the channel feedback information to the sender. The sender comprises an information source coder, a channel coder, a modulator, a power amplifier and a channel feedback and control unit, wherein, the channel feedback and control unit receives the channel feedback information sent from the receiver and according to the average packet loss rate fed back from the channel, a coding mode and a packaging sequence are obtained. A packaging mode as well as the transmitting power and the transmitting time distribution mode of the power amplifier are obtained comprehensively according to the average packet loss rate and that whether a specific data packet is lost. The system of the invention is applicable to the video transmission with energy restriction in a wireless human body area network.
