A video transmission method is provided. The video transmission method includes providing a wireless transmission environment for transmitting a video, wherein the wireless transmission environment includes an application layer, a media access control (MAC) layer and a physical layer; detecting a delay bound and a frame error rate (FER) of the video in the wireless transmission environment; detecting a present packet error rate (PER) of a packet in the physical layer when the physical layer transmits an error report to the MAC layer; calculating an estimated PER; comparing the present PER and the estimated PER for providing a determined result; and calculating an optimal video rate of the video and an optimal payload length of the packet using a geometric programming scheme when the determined result indicates that a retransmission is required, wherein the geometric programming scheme is based on the delay bound and the FER.
