Ship satellite vsat video bandwidth allocation information transmission system and method

The invention discloses a ship satellite VSAT video bandwidth allocation information transmission method which comprises the following steps: receiving a user side trigger signal, transmitting pre-sent information and creating a corresponding information level N; transmitting the message to be sent to an information monitoring unit, and enabling the information monitoring unit to generate a bandwidth occupancy rate M according to the information level; enabling the information monitoring unit to monitor whether the information level N is 1 or not, and if not, executing the next step; enablingthe information monitoring unit to monitor whether the information level N is 2 or not, and if not, executing the next step; and enabling the information monitoring unit to monitor whether the information grade N is 3 or not, enabling the data transmission unit to generate a real-time full-speed bandwidth sending speed K, calculating whether K*M/N is larger than 50 or not, and if yes, performing normal execution.
