The broadcast television program transmission system according to claim 1, wherein the determining module compares the corrected transmission pass rate V "with a preset transmission pass rate V0 when determining the stability of the data transmission of the base station, and determines the stability of the data transmission of the base station according to the comparison result,
when V is less than V0, the judging module judges that the stability of the data transmission of the base station does not meet the requirement;
when V is more than or equal to V0, the judging module judges that the stability of the data transmission of the base station meets the requirement.
8. The system of claim 1, wherein the adjusting module adjusts the data receiving process of the terminal in different ways according to the stability determination result of the data transmission of the base station during the adjustment, wherein,
when the stability of the data transmission of the base station meets the requirement, the adjusting module controls the terminal with data loss to accept the data sent by the base station again;
and when the stability of the data transmission of the base station does not meet the requirement, the adjusting module controls the terminals within the coverage range of the base station to accept the data sent by the base station again.
9. The broadcast television program transmission system according TO claim 1, wherein the check module is configured TO set a check period TO when calculating the check coefficient, and if it is determined that the stability of the base station data transmission does not meet the requirement, the check module sets L time nodes in the check period TO, where L > 1, and obtains the adjusted transmission pass rate Vk at each time node, and determines the stability of the base station data transmission again according TO the adjusted transmission pass rate Vk, and calculates a check coefficient Z, and sets Z = Lk/L, where Lk is the number of times that the determination result in the check period TO meets the requirement for stability.
10. The broadcast television program transmission system according to claim 9, wherein the verification module compares the calculated verification coefficient Z with a preset verification coefficient Z0 and performs verification according to the comparison result, wherein,
when Z is more than or equal to Z0, the check module fails to check and judges that the stability of the data transmission of the base station meets the requirement and external interference exists in the transmission process;
and when Z is less than Z0, the verification module successfully verifies and gives an alarm to prompt that the stability of the data transmission of the base station does not meet the requirement and the base station needs to be overhauled in time.
